Call to order. The meeting was called to order at 9:10 a.m. on January 20, 2015 by Technical Committee (TC) Chair, Dr. Christina Baxter. 2. Welcome & Introductions. Dr. Baxter welcomed everyone to the Second Draft meeting for NFPA 1991 and the First Draft meeting for NFPA 1992 and NFPA 1994. Members and guests introduced themselves and their affiliation. Dr. Baxter thanked everyone for their participation in this meeting to address the public comments received on the first draft of NFPA 1991 and public input on NFPA 1992 and NFPA 1994. She outlined the plan for this meeting. 3. Approval of Minutes. The minutes from the NFPA 1991 First Draft meeting held on September 30 – October 1, 2014 in Dallas/Fort Worth were approved by the TC. 4. NFPA Staff Report and Discussion of Document Revision Process. The NFPA Staff Liaison, Mr. Dave Trebisacci, provided general information on NFPA procedures and timelines in an opening presentation. He addressed NFPA antitrust and patent policies to be adhered to as well as composition and balance of the TC. Mr. Trebisacci stated that the Hazmat TC is in balance. All principal members should designate an alternate member if they have not already done so. NFPA 1991 - Mr. Trebisacci noted that NFPA 1991 is in the fall 2015 cycle and is expected to be on the NFPA Standards Council agenda for approval in November 2015. If approved, NFPA 1991 will carry a 2016 cover date. NFPA 1992 and NFPA 1994 - Additionally, Mr. Trebisacci reminded the TC that NFPA 1992 and NFPA 1994 are in the fall 2016 revision cycle. The Public Input stage of the revision process closed January 5, 2015. A second draft meeting will need to be held between November 2015 and January 2016.

5. Actions on Public Comments to NFPA 1991. Actions that can be taken on the comments are to (1) Accept, (2) Reject, but see related SR, (3) Reject and (4) Reject, but hold. It was noted that any public comments that are determined to be a hold will automatically become Public Input for the next revision to NFPA 1991. Dr. Baxter discussed her review of the comments received and noted that 75% of the comments could be addressed in certain groupings. Issue groupings addressed were: Encapsulating Vs. Non-Encapsulating, Cumulative Permeation vs. Breakthrough Time, MIST vs. SF6, Visor Impact, Flame – Melt vs. Drip, Field of Vision, Single Layer, Flame – Break Open Resistance. During the October 2014 TC meeting, the committee developed an approach which merged the cumulative permeation and breakthrough time measurements. Changes were made throughout the document to address the approach for all chemical permeation testing. Endpoints were finalized. Based on round robin testing conducted since October 2014, values for the MIST performance requirements were established to address the gap left from elimination of the SF6 test. It was agreed that the appropriate respiratory protection for NFPA 1991 is NIOSH certified CBRN SCBA that is also certified to NFPA 1981. Revised criteria was incorporated from public comments for cut resistance and puncture resistance. The new ASTM F2913 will be used for slip resistance testing. New tests for visor high mass resistance and puncture resistance replace old methods. Replacement methods for testing footwear toes and footwear soles and heels were added. The TC decided to move all proposed requirements for non-encapsulating ensembles to a new Class 1 contained in NFPA 1994. Therefore, NFPA 1991 will not contain any non-encapsulating ensemble performance or test requirements. A master response was created to address the substantiation for this action. Suit closure systems were discussed in great detail, and it was decided to include an Annex item to address limitations of current closure technology to educate the end users. Currently the technology does not exist for testing of closures. Inclusion of a test for flame break open resistance was put on hold to allow for manufacturer garment testing and test laboratory validation. Storage life will now be required to be stated in years with the date of manufacture as a basis. A field of view performance requirement was finalized. It was decided that testing across laboratories needs to be conducted with test garments “as worn” to incorporate a test in the next revision to address prediction of body burn. A standard table format was finalized for reporting compliance information as part of technical data requirements.

6. NFPA 1992 Public Input Review. Following extensive discussion, the TC agreed to the importance of maintaining the ability to certify ensemble elements. Language relating to requirements, including definitions, for hoods will be incorporated throughout the standard. In discussing the intent to have NFPA 1992 address materials that are known or suspected human carcinogens, it was decided to include language in the Annex and call attention to the need to conduct a risk assessment for selection/use based upon the hazard. With regard to the definition of bootie, it was generally agreed to change this to emphasize the use of a bootie is intended to be worn inside of a boot. Other high level issues addressed include the potential addition of Evaporative Resistance as an indicator of breathability, incorporation of a new chemical battery, non-encapsulating language, changes to requirements relating to permeation vs. penetration resistance in 7.1.3, the Overall Heat Transfer Performance Test, a fatigue procedure for suit closure assemblies, incorporation of changes relating to visors per NFPA 1991 and specification of the respirator during certification testing. A proposed list of chemicals was developed for section 8.4.4.1 for use in the chemical penetration resistance testing. 7. NFPA 1994 Public Input Review. Discussion occurred on the scope section of the standard to ensure the HazMat operations are addressed in the standard. It was suggested that the title may need to be revised as well. It was also mentioned that garments have been submitted for Class 4, and, therefore, requirements for this class should be maintained. 8. Next Meeting. The next meetings of the Hazmat PC&E TC will be held as teleconferences on January 30, February 4, 6, 13, 16 and 17, 2015. 9. Adjournment. There being no further business before the TC, the meeting adjourned. Respectfully submitted by: Patricia Gleason Secretary NFPA Haz Mat PC&E TC

30 January 2015 Teleconference 0900 – 1200 NFPA 1991 A review of NFPA Table 5.3.1.2 was completed for inclusion in NFPA 1991. There were no other comments from the TC to address. NFPA 1992 The draft, proposed chemical battery prepared at the TC meeting in San Diego was reviewed and modified for inclusion as a committee comment. Testing laboratories will need to provide further input on any testing issues or safety concerns with the proposed list of chemicals, especially Nitric Acid. Manufacturers will also need to conduct preliminary testing to provide the TC feedback on their results. Language was provided to clarify tests in Section 8 for hoods and interfaces to incorporate in NFPA 1991 & NFPA 1992 as needed. Public Inputs were reviewed by the TC in sequential order and updated sections were discussed. 4 February 2015 Teleconference 0900 – 1200 NFPA 1991 Chapters 5, 6, 7 & 8 were sent to the TC for a final review prior to today’s meeting. Clean-up edits were completed by the TC. NFPA 1992 Issues were addressed regarding protective hood elements in sections 6.7. and 7.7. The TC agreed to move forward with changes to the shower test in 8.2 and the overall integrity test in 8.3. Various options were discussed for chemical penetration resistance in 8.4. Additional language was added to address testing closure assemblies with fatigue, testing hood materials after flexing and abrading and testing interface gasket materials. Ten chemicals were kept in the table in 8.4.4.1. Nitric Acid was deleted and Sodium Hydroxide was added. It was suggested that the CAS No.’s and concentrations be listed. The annex will provide explanatory information on how the chemicals were chosen. NFPA 1994 A review of Public Inputs was initiated to allow for consistent actions to be taken as a result of decisions made for NFPA 1991 and NFPA 1992.

6 February 2015 Teleconference 0900 – 1200 NFPA 1994 A table was provided as the basis for review of Public Inputs remaining to be addressed. The TC discussed the Scope and modifications to the title and Chapter 1. The proposed title is Protective Ensembles for First Responders to Hazardous Materials and CBRN Terrorism Incidents. It was decided that a table should be included in the Annex to specify what each of the Haz Mat standards address to compare the property that is evaluated, the test method and measurement used and the performance criteria for each standard. A draft will be provided for the next conference call. For section 5.1.1.9 it was decided to add the total heat loss (THL) Value to the label and break out into 3 components for consistency, i.e. THL, conductive transfer resistance (RCT) and evaporative resistance (RET). A First Revision will be drafted for 6.2.7 for the TC to review. A First Revision will also be drafted for 6.4.10 to address the booties v socks issue. 13 February 2015 Teleconference 0900 – 1200 NFPA 1991 An additional review of NFPA 1991 found errors in 7.3 and 7.5 which were discussed and corrected per the agenda for this call. NFPA 1994 Chapter 8 Public Inputs were reviewed with the goal of maintaining consistency across the project. Concentrations and PAD locations for the MIST test were revised accordingly. Modifications to the liquid tight integrity test were completed. Additionally, more details were provided on the analytical techniques used in permeation testing to correlate with NFPA 1991. Interface gasket material references were incorporated. For the particle inward leakage test it was determined four specimens of any size and two test subjects will be used. Discussion on a new DoD TOP aerosol method for this test concluded with additional information should be provided to the TC prior to further action. It was noted that the full test method will be needed for the second revision step in the cycle. It was decided that correlation testing should occur between certification labs due to high reactivity issues in test conditions and repeatability issues with the test method used for certain challenge chemicals referenced in 8.7.6.3. Necessary language can be drafted based on results. A table will be added to the Annex to explain concentrations used for the various Classes. With regard to elimination of flexing requirements in 8.7.13.4 & .5, the Testing Task Group was requested to explore viable methods for flexing.

It was generally agreed that total heat loss of the certified ensemble is an important performance attribute, and ensemble testing using a thermal mannequin will be incorporated into the draft. The ensemble shall include all elements which were required to meet the protection requirements of the standard such as, but not limited to, garment, respirator, gloves, and boots. It was decided to include Requirements for Total heat loss of the certified ensemble for Classes 2 (when claiming breathability only), 3 & 4 including all elements which were required to meet the protection requirements of the standard. The manufacturer will select one representative certified ensemble configuration for this testing. 16-17 February 2015 Teleconference 0900 – 1200 NFPA 1992 Additional corrections were made to NFPA 1992 in sections 5.1.7, 6.4.4.1, 6.5.5.1 and 7.1.25, 7.6.3 for consistency with NFPA 1991. NFPA 1994 The TC reviewed the 21 chemicals from NFPA 1991 and TIC’s to be incorporated in the Class 1 battery. The TC discussed the need for operationally relevant chemicals and the challenge to obtain consistent data. Following extensive discussion a revised table was drafted. Also discussed were the inclusion of several optional tests including audible signature (NIJ), color (NIJ) and flash fire.

Statement of Problem and Substantiation for Public Comment

CC Note: The following CC Note No. 1992-2015 appeared in the First Draft Report and should be considered by the Committee at the Second Draft Meeting.

Substantiation: There are existing provisions within the standard that prohibit the use of tape as means for providing interfaces between elements of the ensemble, including the respirator facepiece for non-encapsulating ensembles, and other portions of the ensemble such as closures and areas of overlap. However, these provisions only appear as part of reference test methods and not part of the language with the body of the standard.

First Revision No. 109-NFPA 1992-2015 [Section No. 5.2.3]


1 of 1 8/11/2015 1:23 PM


Consideration should be given to whether external fittings and exhaust valves should be evaluatedfor fitting pull out strength, mounting strength, or inward leakage as they are for NFPA 1994. Therespective requirements and test methods are found in 7.1.1.3, 7.1.1.4, and 7.1.1.5 for theperformance requirements and sections 8.6, 8.24, and 8.25 for test methods in NFPA 1994.


Currently, NFPA 1992 does not address any specific requirements for external fittings are exhaust valves though they could be used in these ensembles.

Consistent with the new edition of NFPA 1991, a table with specific attributes should be developedfor reporting the compliance data is part of the Technical Data Package.


A minimum presentation format is needed to ensure that manufactures consistently report the required compliance data required to be part of the Technical Data Package. In NFPA 1991, a specific table was developed and implemented as part of an analogous requirement. These same requirements should be provided for NFPA 1992 especially since some manufacturers seem to believe that reporting information that simply shows greater than the minimum requirement is an adequate basis for representing this information.

Reversion to Previous Procedures in Sections 8.1.5 and 8.1.6

The procedures provided in Sections 8.1.5 and 8.1.6 should be reinstated to the original language providedin the 2012 edition of the NFPA 1992 standard.


While the committee removed the referenced sections due to their impracticality of being performed in conjunction with liquid penetration resistance testing, these conditioning methods were also applied to the overall liquid integrity evaluations of both gloves and footwear and therefore should be retained.

Public Comment No. 8-NFPA 1992-2015 [ New Section after 3.3 ]

Sock – a component of the footwear which is an extension of the garment leg or a separate itemand that covers the entire foot and is worn inside additional foot protective items.


Bootie is frequently misunderstood by end-users, sales people and consultants. As used in this standard a bootie is worn inside other foot protection. In other applications, booties are worn as outer footwear. To avoid confusion among users of this standard, the term “bootie” should be replaced with “sock” which are generally understood as intended to be worn inside outer footwear.

3.3.4 Bootie.

A sock-like extension of the garment or suit leg or a separate sock that covers the entire foot and isintended to be worn inside a protective outer boot.


The definition of the term "biootie" in this standard deals with foot protection worn inside a boot. A large number of users, sales people and consultants do not interpret this tem in this way and may assume that a bootie can be worn as outer footwear. The term "sock" is clearly understand by a great majority of potential users, sales people and consultants as intended to be worn inside outer footwear. The term "bootie" in this standard should be replaced by the term "sock" or "protective sock" to mitigate this potential misunderstanding.

The committee response to FR24 infers that the committee accepted this justification during public input.

A component of an

Material

An exposed material that is not otherwise used as a garment material which provides an interface betweencomponents of the ensemble or ensemble element that provides an interface using an elastomericmaterial. , other than seams, and if applicable the interface between the respirator facepiece and theensemble or ensemble elements..


1. A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Gaskets allow "less-than-perfect" mating surfaces on machine parts where they can fill irregularities. (Wikipedia). Not all interfaces involve a material between two other materials. And the phrase interface gasket is redundant in that a gasket lies within an interface.

2. Interface materials do not have to be made from elastomers

3. The appendix item and the content of the standard also include the interface between the garment and the respirator, when applicable, even though the respirator is not a component or element of compliant ensemble. That distinction should not be buried in the annex.

4. The standard should address exposed interface materials.

5. Seam tape is an interface material already addressed in the standard.

(10) Total heat loss (THL), evaporative resistance (Ret), and insulation value (Rct) as The language"Breathable (see manufacturer's Technical Data Package)" as required by 6.1.5 6


It is proposed that this information be provided in the manufacturer’s Technical Data Package along with other data demonstrating the compliance of the product to the standard. Instead of the THL value, recommendation is made that the words “Breathable (see manufacturer’s Technical Data Package)” be placed on the label. This approach for formatting this information provides a more suitable format for indicating breathable of the garment.

New Paragraph after 5.1.2.2

5.1.2.3

For garments where the integrity of the interfaces between the respirator and hood or suit, between glovesand garment sleeve, and between the footwear and garment legs, has not be evaluated as specified in7.4.1 or 7.5.1, the following warning shall be provided as part of the product label:

"WARNING

THE INTEGRITY OF THE INTERFACES OF THIS GARMENT WITH THE RESPIRATOR, GLOVES, ANDFOOTWEAR HAS NOT BEEN EVALULATED ACCORDING TO THE REQUIERMENTS OF NFPA 1992.USE OF THIS GARMENT IN A LIQUID EXPOSURE ENVIRONMENT MAY RESULT IN LIQUIDPENETRATION THROUGH THESE INTERFACES."


NFPA 1992 permits the certification of individual elements that include garments; however, the overall liquid splash protection provided to the individual wearer is dependent on the integration of garments with a respirator, gloves, and footwear. Since there is no requirement to evaluate the overall liquid penetration resistance of garments with these items, and users need to be aware that the interfaces have not been evaluated.

8.4.9.1

Samples for conditioning shall be whole gloves or glove materials representative of glove construction.

8.4.9.2

Samples shall first be conditioned by flexing as specified in 8.1.3 .

8.4.9.3

Following flexing, a A new sample shall be cut from the flexed whole glove or glove material sample thatmeasures 75 mm × 230 mm (3 in. × 9 in.). The new sample should provide homogeneity across the entirearea.

8.4.9.4 3

The new samples shall then be conditioned by abrading as specified in 8.1.4.

8.4.9.5 4

Following abrasion, only one specimen for penetration resistance testing shall be taken from each samplesubjected to abrasion.

8.4.9.6 5

The penetration test specimen shall be taken from the exact center of the abraded sample so that thecenter of the penetration test and the center of the abraded sample coincide.


The committee recognized that the earlier edition flexing procedures for both gloves and footwear do not yield the intended results because the nature the samples prevents flexing portions of either gloves or footwear that provide adequate specimens for both abrasion and liquid penetration resistance testing. As no specific replacement flexing criteria have been developed, is recommended that these two sections be deleted. The proposed change removes the flexing procedure as a preconditioning technique for gloves.

8.4.10.2

Samples for conditioning shall be whole footwear items or footwear materials representative of the footwearupper construction.

8.4.10.3

Samples shall first be conditioned by flexing as specified in 8.1.3 .

8.4.10.4

Following flexing, new New samples shall be taken in areas from the footwear upper where the greatestflexing occurred, usually at the footwear quarter or vamp, or footwear material measuring 75 mm × 230mm (3 in. × 9 in.). An attempt shall be made to choose new samples areas that are homogeneous.

8.4.10.5 4

The new samples shall then be conditioned by abrading as specified in 8.1.4.

8.4.10.6 5

Following abrasion, only one specimen for penetration resistance testing shall be taken from each samplesubjected to abrasion.

8.4.10.7 6

The penetration test specimen shall be taken from the exact center of the abraded sample so that thecenter of the penetration test and the center of the abraded sample coincide.


The committee recognized that the earlier edition flexing procedures for both gloves and footwear do not yield the intended results because the nature the samples prevents flexing portions of either gloves or footwear that provide adequate specimens for both abrasion and liquid penetration resistance testing. As no specific replacement flexing criteria have been developed, is recommended that these two sections be deleted. The proposed change removes the flexing procedure as a preconditioning technique for footwear.

A.8.4.4.1


87 of 89 11/24/2015 11:55 AM

Liquid penetration resistance testing assesses whether liquids will pass through a material or seam underspecified conditions of exposure. Chemicals will penetrate materials and seams because either thechemical has low surface tension that allows the liquid chemical to seep through holes or pores in thematerial or seam, or due to degradation of the chemical interacting with the material that can causedeterioration of the material to the extent that creates physical penetration pathways for liquid passage.

The chemicals for chemical penetration resistance testing are chosen from ASTM F1001, Standard Guidefor Selection of Chemicals to Evaluate Protective Clothing Materials, and other relevant chemicalsaccording to the following factors:

(1) Chemicals were included from the ASTM F1001 list if the chemical was a low-volatility liquid with avapor pressure less than 5 mm Hg at 20°C.

(2) Liquid chemicals from the ASTM F1001 list that have vapor pressures above 5 mm Hg at 20°C but donot have a skin notation and are not classified as a human carcinogen according to ACGIH’sThreshold Limit Values For Chemical Substances and Physical Agents and Biological ExposureIndices or the NIOSH Pocket Guide to Chemical Hazards

(3) Substitute chemicals were chosen for relatively volatile chemicals that were of the same generalchemical classification but with a lower vapor pressure than the comparable ASTM F1001 liquidchemical that also did not have a skin notation as indicated in A.8.4.4.1(2). These substitutions includemethyl isobutyl ketone for acetone and butyl acetate for ethyl acetate. Less volatile chemicals areeasier to observe if the chemical penetrates the material.

(4) Some chemicals were chosen on the basis of their known degradation effects on a wide range ofelastomeric and polymeric materials used in various forms of protective clothing.

(5) Fuel C, a mixture of equal volumes of toluene and iso-octane, was chosen to represent a broad rangeof hydrocarbons.

(6) Sodium hypochlorite was chosen as a chemical representative of harsh disinfectant that can causedegradation of different clothing materials that could lead to lead to liquid penetration of materials orseams.

(7) Nitric acid was chosen to represent a different type of corrosive inorganic acid.

(8) Isopropanol, while having a relatively high vapor pressure, was selected on the basis of its lowsurface tension.

Table A.8.4.4.1 summarizes important characteristics and reasoning for the selection of the chemicals.

REORGANIZATION OF CHAPTER 7 CRITERIA TO ADDRESS RUGGEDIZED REQUIREMENTS

It is proposed to establish a higher level a ruggedized performance for each class of ensemble with theexception of class 1 that already is set at this higher level. The principal to be applied is to createruggedized requirements in two parts:

(1) higher levels of physical properties should be specified for the garment and glove materials that areconsistent with either the current proposed Class 1 criteria such as burst strength and puncturepropagation tear resistance for garment materials; and

(2) more rigorous flexing and abrasion preconditioning should be performed on garment materials usingthe current Gelbo flex and Wyzenbeek abrasion procedures at 10 times their current specified number ofcycles.

For Classes 2, 3, and 4, there would be a standard and a ruggedized category of ensemble performance.Additional changes are needed in the scope and purpose of the standard.


The Correlating Committee has directed the Technical Committee to encompass additional categories of ruggedized Class 2 protection originally provided as part of NFPA 1971-2013, ruggedized Class 3 protection originally provided as part of NFPA 1951-2013, and ruggedized Class 4 protection originally provided as NFPA 1999-2013. The proposed hierarchy is an approach to address the specific requirements to differentiate between existing standard ensembles and or ruggedized ensembles that are capable of multiple uses or more extreme environments. Information gained from investigation of physical requirements for law enforcement CBRN ensembles are appropriate starting point for these criteria.

Expanded Technical Data Package

Consistent with the new edition of NFPA 1991, a table with specific attributes should be developedfor reporting the compliance data is part of the Technical Data Package.


A minimum presentation format is needed to ensure that manufactures consistently report the required compliance data required to be part of the Technical Data Package. In NFPA 1991, a specific table was developed and implemented as part of an analogous requirement. These same requirements should be provided for NFPA 1992 especially since some manufacturers seem to believe that reporting information that simply shows greater than the minimum requirement is an adequate basis for representing this information.

Reversion to the prior Particle Inward Leakage Test

It is proposed to return the language of section 8.5 to the original language in the 2012 edition ofNFPA 1994 with the exception that additional assays of individual test subjects can be performedin the event of results that cannot be easily interpreted.


An extensive rewrite of the Particle Inward Leakage Test found in Section 8.5 because up until the time of the First Draft meeting, testing according to these procedures had not been performed. Since that meeting, relatively large number of tests (approximately 32) have been performed using the 2012 edition language and the concerns related to being able to interpret results as passing or failing performance have not materialized. Nevertheless, it is proposed that a provision be provided as part of the testing using some of the newly proposed language to provide a means of refereeing any portions of the black undergarments that may show the potential for fluorescent particle presence.

Addition of Moisture Vapor Transmission Test for Class 4 Ensembles

Adopt the MVTR test method and criteria from NFPA 1999 for an alternative means of characterizing thestress relief and breathability of NFPA 1994 Class 4 ensemble garment materials.


Very light materials could be considered as offerings for NFPA 1994 Class 4 performance. As was demonstrated in the Temporary Interim Amendment for NFPA 1999 wear single use garments were evaluated for total heat loss, difficulties encountered for conducting these tests with very lightweight materials required consideration of a different approach for characterizing material breathability. The approach used in NFPA 1999 should be considered as a potential alternative test for evaluating material breathability.

Bootie is frequently misunderstood by end-users, sales people and consultants. As used in this standard a bootie is worn inside other foot protection. In other applications, booties are worn as outer footwear. To avoid confusion among users of this standard, the term “bootie” should be replaced with “sock” which is generally understood as intended to be worn inside outer footwear.

To avoid confusion among users of this standard, the term “bootie” should be replaced with “sock” which is generally understood as intended to be worn inside outer footwear.

3.3.46 Interface Gasket.

A component of an ensemble or ensemble element that provides an interface using an elastomeric material

Material

An exposed material that is not otherwise used as garment material which provides an interfacebetween components of the ensemble and ensemble elements, other than seams, and if applicablebetween the respirator facepiece and the ensmble or ensemble elements .


1. A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Gaskets allow "less-than-perfect" mating surfaces on machine parts where they can fill irregularities. (Wikipedia). Not all interfaces involve a material between two other materials. And the phrase interface gasket is redundant in that a gasket lies within an interface.

2. Interface materials do not have to be made from elastomers

3. The appendix item and the content of the standard also include the interface between the garment and the respirator, when applicable, even though the respirator is not a component or element of compliant ensemble. That distinction should not be buried in the annex.

4. The standard should address exposed interface materials

5. Seam tape is an interface material but already covered

Three decades of experience after having created the standard battery of chemicals in ASTM F 1001 combined with its application in a variety of standards for investigating the broad chemical resistance of protective clothing materials has revealed that there is some redundancy and chemicals within the list that do not yield useful information in predicting the overall chemical resistance of materials. The proposed deletion of chemicals helps to keep the number of evaluations to a more manageable level while still serving to provide an adequate assessment of overall performance.

NEW TEST METHOD IN SECTION 8

8.35 Total Evaporative Resistance Test.

8.35.1 Application. This test method shall apply to the suit based composite designated as breathable.

8.35.2 Samples.

8.35.2.1 Samples shall be conditioned at a temperature of 25°C ± 7°C (77°F ± 13°F), and a relativehumidity of 65 percent ± 5 percent, for at least 4 hours.

8.35.2.2 The minimum sample size shall be 51 cm × 51 cm (20 in. × 20 in.).

8.35.3 Specimens.

8.35.3.1 Specimen size shall be the size required to cover the sweating guarded hot plate.

8.35.3.2 Evaporative resistance testing shall be conducted on at least three specimens.

8.35.3.3 Specimens shall consist of all layers in the protective garment composite, arranged in the orderand orientation as worn and shall not include any reinforcement materials.

8.35.4 Apparatus.

8.35.4.1 The test apparatus shall be as specified in ASTM F 1868, Standard Test Method for Thermal andEvaporative Resistance of Clothing Materials Using a Sweating Hot Plate .

8.35.4.2 The dimensions for the sweating guarded hot plate shall be a 25.4 cm (10 in.) test plate with a12.7 cm (5 in.) guard surrounding the test plate.

8.35.5* Procedure.

Testing shall be conducted in accordance with ASTM F 1868, Standard Test Method for Thermal andEvaporative Resistance of Clothing Materials Using a Sweating Hot Plate , using Part B, with the followingmodifications:

(1) The isothermal method shall be used.

(2) The specimen shall be placed on the test plate with the side normally facing the human body towardthe test plate.

(3) For multiple layers the layers shall be arranged in the order and orientation as worn.

(4) Each layer shall be smoothed by hand to eliminate wrinkles or bubbles in each layer and, if necessary,secure the edges.

(5) Once the test is started, no further adjustments to the specimen shall be made.

8.35.6 Report.

8.35.6.1 The total evaporative resistance ( R et ) of each sample shall be recorded and reported.

8.35.6.2 The average total evaporative resistance ( R et ) of all tested samples shall be recorded and

reported.


8.35.7.1 Pass or fail determination shall be based on the average reported total evaporative resistance ( R

et ) measurement of all specimens tested.

8.35.7.2 If an individual result from any test set varies more than ±10 percent from the average result, theresults from the test set shall be discarded and another set of specimens shall be tested.


The measurement of Ret actually differs from the measurement of the apparent evaporative resistance is determined in evaluation of total heat loss (THL). The primary difference is that Ret is measured isothermally whereas apparent evaporative resistance for THL is measured with an environment to plate temperature difference of 10°C. The proposed change provides a new test method for the measurement of Ret.
