ð15Þ FOREWORD*

In 1911, The American Society of Mechanical Engineers established the Boiler and Pressure Vessel Committee to for-mulate standard rules for the construction of steam boilers and other pressure vessels. In 2009, the Boiler and PressureVessel Committee was superseded by the following committees:

(a) Committee on Power Boilers (I)(b) Committee on Materials (II)(c) Committee on Construction of Nuclear Facility Components (III)(d) Committee on Heating Boilers (IV)(e) Committee on Nondestructive Examination (V)(f) Committee on Pressure Vessels (VIII)(g) Committee on Welding, Brazing, and Fusing (IX)(h) Committee on Fiber-Reinforced Plastic Pressure Vessels (X)(i) Committee on Nuclear Inservice Inspection (XI)(j) Committee on Transport Tanks (XII)(k) Technical Oversight Management Committee (TOMC)Where reference is made to “the Committee” in this Foreword, each of these committees is included individually and

collectively.The Committee’s function is to establish rules of safety relating only to pressure integrity, which govern the

construction** of boilers, pressure vessels, transport tanks, and nuclear components, and the inservice inspection of nu-clear components and transport tanks. The Committee also interprets these rules when questions arise regarding theirintent. The technical consistency of the Sections of the Code and coordination of standards development activities of theCommittees is supported and guided by the Technical Oversight Management Committee. This Code does not addressother safety issues relating to the construction of boilers, pressure vessels, transport tanks, or nuclear components, orthe inservice inspection of nuclear components or transport tanks. Users of the Code should refer to the pertinent codes,standards, laws, regulations, or other relevant documents for safety issues other than those relating to pressure integ-rity. Except for Sections XI and XII, and with a few other exceptions, the rules do not, of practical necessity, reflect thelikelihood and consequences of deterioration in service related to specific service fluids or external operating environ-ments. In formulating the rules, the Committee considers the needs of users, manufacturers, and inspectors of pressurevessels. The objective of the rules is to afford reasonably certain protection of life and property, and to provide a marginfor deterioration in service to give a reasonably long, safe period of usefulness. Advancements in design and materialsand evidence of experience have been recognized.

This Code contains mandatory requirements, specific prohibitions, and nonmandatory guidance for construction ac-tivities and inservice inspection and testing activities. The Code does not address all aspects of these activities and thoseaspects that are not specifically addressed should not be considered prohibited. The Code is not a handbook and cannotreplace education, experience, and the use of engineering judgment. The phrase engineering judgement refers to tech-nical judgments made by knowledgeable engineers experienced in the application of the Code. Engineering judgmentsmust be consistent with Code philosophy, and such judgments must never be used to overrule mandatory requirementsor specific prohibitions of the Code.

The Committee recognizes that tools and techniques used for design and analysis change as technology progressesand expects engineers to use good judgment in the application of these tools. The designer is responsible for complyingwith Code rules and demonstrating compliance with Code equations when such equations are mandatory. The Codeneither requires nor prohibits the use of computers for the design or analysis of components constructed to the

Therefore, this Foreword may contain material that has not been subjected to public review or a con-sensus process. In addition, it does not contain requirements necessary for conformance to the Code.

requirements of the Code. However, designers and engineers using computer programs for design or analysis are cau-tioned that they are responsible for all technical assumptions inherent in the programs they use and the application ofthese programs to their design.The rules established by the Committee are not to be interpreted as approving, recommending, or endorsing any pro-

prietary or specific design, or as limiting in any way the manufacturer's freedom to choose any method of design or anyform of construction that conforms to the Code rules.The Committee meets regularly to consider revisions of the rules, new rules as dictated by technological development,

Code Cases, and requests for interpretations. Only the Committee has the authority to provide official interpretations ofthis Code. Requests for revisions, new rules, Code Cases, or interpretations shall be addressed to the Secretary in writingand shall give full particulars in order to receive consideration and action (see Submittal of Technical Inquiries to theBoiler and Pressure Vessel Standards Committees). Proposed revisions to the Code resulting from inquiries will be pre-sented to the Committee for appropriate action. The action of the Committee becomes effective only after confirmationby ballot of the Committee and approval by ASME. Proposed revisions to the Code approved by the Committee are sub-mitted to the American National Standards Institute (ANSI) and published at http://go.asme.org/BPVCPublicReview toinvite comments from all interested persons. After public review and final approval by ASME, revisions are published atregular intervals in Editions of the Code.The Committee does not rule on whether a component shall or shall not be constructed to the provisions of the Code.

The scope of each Section has been established to identify the components and parameters considered by the Committeein formulating the Code rules.Questions or issues regarding compliance of a specific component with the Code rules are to be directed to the ASME

Certificate Holder (Manufacturer). Inquiries concerning the interpretation of the Code are to be directed to the Commit-tee. ASME is to be notified should questions arise concerning improper use of an ASME Certification Mark.When required by context in this Section, the singular shall be interpreted as the plural, and vice versa, and the fem-

inine, masculine, or neuter gender shall be treated as such other gender as appropriate.

STATEMENT OF POLICY ON THE USE OF THE CERTIFICATIONMARK AND CODE AUTHORIZATION IN ADVERTISING

ASME has established procedures to authorize qualified organizations to perform various activities in accordancewith the requirements of the ASME Boiler and Pressure Vessel Code. It is the aim of the Society to provide recognitionof organizations so authorized. An organization holding authorization to perform various activities in accordance withthe requirements of the Code may state this capability in its advertising literature.

Organizations that are authorized to use the Certification Mark for marking items or constructions that have beenconstructed and inspected in compliance with the ASME Boiler and Pressure Vessel Code are issued Certificates ofAuthorization. It is the aim of the Society to maintain the standing of the Certification Mark for the benefit of the users,the enforcement jurisdictions, and the holders of the Certification Mark who comply with all requirements.

Based on these objectives, the following policy has been established on the usage in advertising of facsimiles of theCertification Mark, Certificates of Authorization, and reference to Code construction. The American Society of MechanicalEngineers does not “approve,” “certify,” “rate,” or “endorse” any item, construction, or activity and there shall be no state-ments or implications that might so indicate. An organization holding the Certification Mark and/or a Certificate ofAuthorization may state in advertising literature that items, constructions, or activities “are built (produced or per-formed) or activities conducted in accordance with the requirements of the ASME Boiler and Pressure Vessel Code,”or “meet the requirements of the ASME Boiler and Pressure Vessel Code.”An ASME corporate logo shall not be usedby any organization other than ASME.

The Certification Mark shall be used only for stamping and nameplates as specifically provided in the Code. However,facsimiles may be used for the purpose of fostering the use of such construction. Such usage may be by an association ora society, or by a holder of the Certification Mark who may also use the facsimile in advertising to show that clearly spe-cified items will carry the Certification Mark. General usage is permitted only when all of a manufacturer’s items areconstructed under the rules.

STATEMENT OF POLICY ON THE USE OF ASME MARKING TOIDENTIFY MANUFACTURED ITEMS

The ASME Boiler and Pressure Vessel Code provides rules for the construction of boilers, pressure vessels, and nuclearcomponents. This includes requirements for materials, design, fabrication, examination, inspection, and stamping. Itemsconstructed in accordance with all of the applicable rules of the Code are identified with the official Certification Markdescribed in the governing Section of the Code.

Markings such as “ASME,” “ASME Standard,” or any other marking including “ASME” or the Certification Mark shall notbe used on any item that is not constructed in accordance with all of the applicable requirements of the Code.

Items shall not be described on ASME Data Report Forms nor on similar forms referring to ASME that tend to implythat all Code requirements have been met when, in fact, they have not been. Data Report Forms covering items not fullycomplying with ASME requirements should not refer to ASME or they should clearly identify all exceptions to the ASMErequirements.

ð15Þ SUBMITTAL OF TECHNICAL INQUIRIES TO THE BOILER ANDPRESSURE VESSEL STANDARDS COMMITTEES

1 INTRODUCTION

(a) The following information provides guidance to Code users for submitting technical inquiries to the committees.See Guideline on the Approval of New Materials Under the ASME Boiler and Pressure Vessel Code in Section II, Parts Cand D for additional requirements for requests involving adding new materials to the Code. Technical inquiries includerequests for revisions or additions to the Code rules, requests for Code Cases, and requests for Code Interpretations, asdescribed below.

(1) Code Revisions. Code revisions are considered to accommodate technological developments, address administra-tive requirements, incorporate Code Cases, or to clarify Code intent.

(2) Code Cases. Code Cases represent alternatives or additions to existing Code rules. Code Cases are written as aquestion and reply, and are usually intended to be incorporated into the Code at a later date. When used, Code Casesprescribe mandatory requirements in the same sense as the text of the Code. However, users are cautioned that notall jurisdictions or owners automatically accept Code Cases. The most common applications for Code Cases are:

(-a) to permit early implementation of an approved Code revision based on an urgent need

(-b) to permit the use of a new material for Code construction

(-c) to gain experience with new materials or alternative rules prior to incorporation directly into the Code

(3) Code Interpretations. Code Interpretations provide clarification of the meaning of existing rules in the Code, andare also presented in question and reply format. Interpretations do not introduce new requirements. In cases whereexisting Code text does not fully convey the meaning that was intended, and revision of the rules is required to supportan interpretation, an Intent Interpretation will be issued and the Code will be revised.

(b) The Code rules, Code Cases, and Code Interpretations established by the committees are not to be considered asapproving, recommending, certifying, or endorsing any proprietary or specific design, or as limiting in any way the free-dom of manufacturers, constructors, or owners to choose any method of design or any form of construction that con-forms to the Code rules.

(c) Inquiries that do not comply with these provisions or that do not provide sufficient information for a committee’sfull understanding may result in the request being returned to the inquirer with no action.

2 INQUIRY FORMAT

Submittals to a committee shall include:

(a) Purpose. Specify one of the following:

(1) revision of present Code rules

(2) new or additional Code rules

(3) Code Case

(4) Code Interpretation

(b) Background. Provide the information needed for the committee’s understanding of the inquiry, being sure to in-clude reference to the applicable Code Section, Division, edition, addenda (if applicable), paragraphs, figures, and tables.Preferably, provide a copy of the specific referenced portions of the Code.

(c) Presentations. The inquirer may desire or be asked to attend a meeting of the committee to make a formal presen-tation or to answer questions from the committee members with regard to the inquiry. Attendance at a committee meet-ing shall be at the expense of the inquirer. The inquirer’s attendance or lack of attendance at a meeting shall not be abasis for acceptance or rejection of the inquiry by the committee.

INTRODUCTION

1 GENERAL

The use of fiber-reinforced plastics for the manufacture of pressure vessels presents unique materials considerationsin the design, fabrication, and testing of these vessels. Metallic vessels, being made from materials which are normallyisotropic and ductile, are designed by using well-established allowable stresses based on measured tensile and ductilityproperties. In contrast, fiber-reinforced plastics are usually anisotropic and the physical properties are dependent uponthe fabrication process, the placement and orientation of the reinforcement, and the resin matrix. It is the purpose of thisIntroduction to describe in a general way the criteria that were used in preparing Section X, Fiber-Reinforced PlasticPressure Vessels. A list of standards referenced in this Section is provided in Table 1.1.

2 MATERIALS

It is not possible to fabricate a reinforced plastic pressure vessel of a single basic material for which there is an ASTMspecification. The vessel parts are made up of various basic materials, such as fiber reinforcement and resin, which arejoined in the presence of a catalyst to create a composite material that is formed into a vessel or vessel part by a specifiedprocess. The composite material will often have directional properties which shall be considered in design. General spe-cifications for the basic materials (fiber reinforcement and resin) are stated, as are requirements for determination ofelastic properties for the composite material (laminate) produced. Elastic properties of specific laminates used in vesselfabrication are required when mandatory rules are used for vessel design. Metallic materials, when used in conjunctionwith reinforced fiber laminates, are required to meet ASME Boiler and Pressure Vessel Code specifications, Section VIII,Division 1. That Section must be used for the design, fabrication, quality control, and inspection of such metallic parts.However, for hydrostatic leakage testing, these metallic materials that complete the vessel are required to meet SectionX requirements.

3 DESIGN

3.1 GENERAL3.1.1 Adequacy of specific designs shall be qualified by one of the following methods:1

(a) Class I Design — qualification of a vessel design through the pressure testing of a prototype.

(b) Class II Design — mandatory design rules and acceptable testing by nondestructive methods.

(c) Class III Design— qualification of a vessel design through the pressure testing of a prototype, other specified testsof prototypes, mandatory design rules and acceptance testing by nondestructive methods.

3.1.2 Class I designs based on the qualification of a prototype vessel require that the minimum qualification pres-sure of the prototype be at least six2 times the design pressure. The maximum design pressure is limited to 150 psi(1 MPa) for bag-molded, centrifugally cast, and contact-molded vessels; 1,500 psi (10 MPa) for filament-wound vessels;and 3,000 psi (20 MPa) for filament-wound vessels with polar boss openings.

3.1.3 Class II designs based on mandatory design rules and acceptance testing must comply with Article RD-11 andArticle RT-6. The maximum design pressure allowed under this procedure shall be as specified in RD-1120.

3.1.4 Class III designs include the qualification of a prototype with the minimum qualification pressure of the pro-totype to be at 2.25 times the design pressure for carbon fiber vessels, and 3.5 times the design pressure for glass fibervessels. Hybrid designs using more than one type of fiber are covered in 8-400.7. The maximum design pressure is lim-ited to 15,000 psi (103 MPa). The minimum design pressure shall be not less than 3,000 psi (20.7 MPa).

1 These three methods shall not be intermixed.2 An exception to this six times factor is applicable to vessels per (Filament Winding — Polar Boss Openings Only).

3.2 LOW MODULUS CHARACTERISTICS

Fiber-reinforced plastic laminates may have a modulus of elasticity as low as 1.0 × 106 psi (6 900 MPa), comparedwith that of ferrous materials which may be of the order of 30 × 106 psi (2.1 × 105 MPa). This lowmodulus characteristicrequires careful consideration of vessel profile in order to minimize bending and avoid buckling. Spherical heads or el-liptical heads having an ellipse ratio not greater than 2:1 are suggested. Spherical heads are suggested when the materialhas isotropic properties. Elliptical heads are preferred when the material has anisotropic properties.

3.3 FATIGUE3.3.1 Like metallic materials, the composite material (laminate) of fiber-reinforced plastic vessels, when stressed at

sufficiently low levels, exhibits good fatigue life. However, its low modulus of elasticity provides a higher strain per unitof stress than metals used for metallic vessels.

3.3.2 Section X, therefore, requires that a Class I design that is qualified by testing of a prototype vessel be pressurecycled 100,000 times over a pressure range of atmospheric to the design pressure; after this, the test vessel must with-stand a hydrostatic qualification test not less than six times the design pressure. An exception to this 100,000 cycle re-quirement is applicable to vessels per RG-404.2 (Filament Winding — Polar Boss Openings Only). That classification ofvessels is designed for a 5:1 factor of safety which requires cycling from atmospheric to the design pressure for 33,000cycles; after this, the test vessel must withstand a hydrostatic qualification test not less than five times the designpressure.

3.3.3 Class II vessels qualified using mandatory design rules and acceptance testing are not required to be subjectedto the above cyclic and qualification pressure test criteria.

3.3.4 Section X requires that a Class III design qualification include testing of a prototype vessel that is pressurecycled for “N” cycles as prescribed in 8-700.5.4.1 over a pressure range of 10% of design pressure to 100% of designpressure without leakage or rupture; then followed by additional cycles until the vessel leaks or a total of 2 times“N” cycles have been reached.

3.4 CREEP, STRESS-RUPTURE, AND TEMPERATURE EFFECTS

Fiber-reinforced plastic composite material (laminate) is not subject to creep or failure due to low stress-to-rupturecharacteristics as are some other materials. The material does, however, lose ultimate strength as the temperature isincreased and gains strength but becomes more brittle as the temperature is lowered. Its low thermal conductivityand ablative properties are other factors significantly affecting the behavior of this material in the event of fire or otherhigh-temperature environment. The maximum design, operating, and test temperatures of Class I vessels are set asfollows:

(a) 150°F (65°C) for design temperatures less than or equal to 150°F (65°C);(b) 250°F (120°C) or to within 35°F (19°C) of the glass transition temperature (whichever is lower) for design tem-

peratures in excess of 150°F (65°C).The maximum design, operating, and test temperatures of Class II vessels are limited to an inside wall temperature of

250°F (120°C) or to within 35°F (19°C) of the glass transition temperature of the resin (whichever is lower). The max-imum design temperature of Class III vessels shall be 35°F (19°C) below the maximum use temperature of the resin asdocumented in the Manufacturing Specifications, but in no case shall it exceed 185°F (85°C). The minimum design tem-perature of Class I, Class II, and Class III vessels shall be −65°F (−54°C) (see RD-112).

3.5 FABRICATION3.5.1 Many processes are used in the fabrication of fiber-reinforced composite materials (laminates). Class I vessels

are limited to four processes, namely, filament winding, bag molding, contact molding, and centrifugal casting. Class IIvessels are limited to two processes, namely, filament winding and contact molding.

3.5.2 The fabrication of more than one Class I vessel may be required to comply with the requirements for qualify-ing a design using the prototype vessel3 method. Once a specific design has been qualified, the quality of subsequentvessels of the same dimension and design is to be assured by carefully controlled fabrication procedures and rigid Qual-ity Control Programs.

3.5.3 Every Class II vessel must be acceptance tested as specified in Article RT-6. Such tests must be documented ashaving met the acceptance criteria of Article RT-6 and shall become part of the Fabricator’s Design Report.

3.5.4 Class III vessels are limited to filament-wound construction with polar loss openings.

3 Prototype vessels used to qualify a design shall not be stamped with the Certification Mark.

3.6 INSPECTION

3.6.1 The general philosophy of Section VIII, Division 1, regarding inspection during fabrication is continued in thisSection. Familiarity with the laminate production processes and the nature of vessel imperfections is required of theInspector. Reliance is placed upon careful auditing of the Fabricator’s Quality Control Program, close visual inspectionof completed vessels by both Fabricator personnel and the Inspector, and acceptance testing where required by thisSection.

3.6.2 This Section requires that all laminate and secondary bonding work be without use of pigments, fillers, orresin putty mixtures except as permitted by the Procedure Specification used in fabricating the vessel or vessel part.

3.7 LINERS

Liners may be used in Section X vessels as a barrier between the laminate and the vessel contents. Such liners shall notbe considered part of the structural component of the vessel.

3.8 UNITS

3.8.1 Either U.S. Customary, SI, or any local customary units may be used to demonstrate compliance with all re-quirements of this Edition (e.g., materials, design, fabrication, examination, inspection, testing, certification, and over-pressure protection).

3.8.2 In general, it is expected that a single system of units shall be used for all aspects of design except where un-feasible or impractical. When components are manufactured at different locations where local customary units are dif-ferent than those used for the general design, the local units may be used for the design and documentation of thatcomponent. Similarly, for proprietary components or those uniquely associated with a system of units different than thatused for the general design, the alternate units may be used for the design and documentation of that component.

3.8.3 For any single equation, all variables shall be expressed in a single system of units. When separate equationsare provided for U.S. Customary units and SI units, those equations must be executed using variables in the units asso-ciated with the specific equation. Data expressed in other units shall be converted to U.S. Customary units or SI units foruse in these equations. The result obtained from execution of these equations may be converted to other units.

3.8.4 Production, measurement and test equipment, drawings, welding procedure specifications, welding proce-dure and performance qualifications, and other fabrication documents may be in U.S. Customary, SI, or local customaryunits in accordance with the fabricator’s practice. When values shown in calculations and analysis, fabrication docu-ments, or measurement and test equipment are in different units, any conversions necessary for verification of Codecompliance and to ensure that dimensional consistency is maintained, shall be in accordance with the following:

(a) Conversion factors shall be accurate to at least four significant figures.

(b) The results of conversions of units shall be expressed to a minimum of three significant figures.

3.8.5 Material that has been manufactured and certified to either the U.S. Customary or SI material specification(e.g., SA-516M) may be used regardless of the unit system used in design. Standard fittings (e.g., flanges, elbows, etc.)that have been certified to either U.S. Customary units or SI units may be used regardless of the units system used indesign.

3.8.6 Conversion of units, using the precision specified in para. 20, shall be performed to assure that dimensionalconsistency is maintained. Conversion factors between U.S. Customary units and SI units may be found in the Nonman-datory Appendix, Guidance for the Use of U.S. Customary and SI units in the ASME Boiler and Pressure Vessel Code.Whenever local customary units are used, the Manufacturer shall provide the source of the conversion factors whichshall be subject to verification and acceptance by the Authorized Inspector or Certified Individual.

3.8.7 All entries on a Manufacturer’s Data Report and data for Code required nameplate marking shall be in unitsconsistent with the fabrication drawings for the component using U.S. Customary, SI, or local customary units. It is ac-ceptable to show alternate units parenthetically. Users of this Code are cautioned that the receiving Jurisdiction shouldbe contacted to ensure the units are acceptable.

CROSS-REFERENCING AND STYLISTIC CHANGES IN THE BOILERAND PRESSURE VESSEL CODE

There have been structural and stylistic changes to BPVC, starting with the 2011 Addenda, that should be noted to aidnavigating the contents. The following is an overview of the changes:

Subparagraph Breakdowns/Nested Lists Hierarchy

• First-level breakdowns are designated as (a), (b), (c), etc., as in the past.• Second-level breakdowns are designated as (1), (2), (3), etc., as in the past.• Third-level breakdowns are now designated as (-a), (-b), (-c), etc.• Fourth-level breakdowns are now designated as (-1), (-2), (-3), etc.• Fifth-level breakdowns are now designated as (+a), (+b), (+c), etc.• Sixth-level breakdowns are now designated as (+1), (+2), etc.

Footnotes

With the exception of those included in the front matter (roman-numbered pages), all footnotes are treated as end-notes. The endnotes are referenced in numeric order and appear at the end of each BPVC section/subsection.

Submittal of Technical Inquiries to the Boiler and Pressure Vessel Standards Committees

Submittal of Technical Inquiries to the Boiler and Pressure Vessel Standards Committees has been moved to the frontmatter. This information now appears in all Boiler Code Sections (except for Code Case books).

Cross-References

It is our intention to establish cross-reference link functionality in the current edition and moving forward. To facil-itate this, cross-reference style has changed. Cross-references within a subsection or subarticle will not include the des-ignator/identifier of that subsection/subarticle. Examples follow:

• (Sub-)Paragraph Cross-References. The cross-references to subparagraph breakdowns will follow the hierarchy ofthe designators under which the breakdown appears.– If subparagraph (-a) appears in X.1(c)(1) and is referenced in X.1(c)(1), it will be referenced as (-a).– If subparagraph (-a) appears in X.1(c)(1) but is referenced in X.1(c)(2), it will be referenced as (1)(-a).– If subparagraph (-a) appears in X.1(c)(1) but is referenced in X.1(e)(1), it will be referenced as (c)(1)(-a).– If subparagraph (-a) appears in X.1(c)(1) but is referenced in X.2(c)(2), it will be referenced as X.1(c)(1)(-a).

• Equation Cross-References. The cross-references to equations will follow the same logic. For example, if eq. (1) ap-pears in X.1(a)(1) but is referenced in X.1(b), it will be referenced as eq. (a)(1)(1). If eq. (1) appears in X.1(a)(1) butis referenced in a different subsection/subarticle/paragraph, it will be referenced as eq. X.1(a)(1)(1).

INTENTIONALLY LEFT BLANK

PART RGGENERAL REQUIREMENTS

ARTICLE RG-1SCOPE AND JURISDICTION

RG-100 SCOPE

(a) Section X establishes the requirements for the fabri-cation of fiber‐reinforced thermosetting plastic pressurevessels for general service, sets limitations on the permis-sible service conditions, and defines the types of vesselsto which these rules are not applicable.

(b) To assure that vessels fabricated according to theserules will be capable of safely withstanding the operatingconditions specified by the Design Specification, thisSection:

(1) gives minimum requirements for the materials offabrication;

(2) specifies test procedures for determining lami-nate mechanical properties;

(3) Defines three methods of design qualification:

(-a) Class I Design — nondestructive qualificationtest

(-b) Class II Design—mandatory design rules andacceptance testing by nondestructive evaluation (NDE)methods

(-c) Class III Design— qualification of a vessel de-sign through the destructive test of a prototype

(4) suggests nonmandatory design procedures forClass I vessels;

(5) provides mandatory design procedures and ac-ceptance testing for Class II vessels;

(6) defines the general methods of fabrication whichmay be used;

(7) limits the types of end closures, connections, andattachments which may be employed and the means usedto join them to the vessels;

(8) stipulates the procedures to be used in provingthat prototype vessels will withstand specified operatingand test conditions;

(9) establishes rules under which fabricating proce-dures used for fabricating Class I and Class III prototypeand production vessels are qualified, and defines what de-viations from such procedures necessitate requalification;

(10) sets forth requirements to assure that no essen-tial variation in qualified fabrication procedures hasoccurred;

(11) establishes rules for acceptance testing, inspec-tion, and reporting;

(12) gives requirements for stamping and marking.(c) For vessels fabricated in accordance with these

rules, the provisions of Section X shall apply over anyother sections of the Code. When metallic componentsare part of fiber‐reinforced plastic vessels, they shall meetthe provisions of Section VIII, Division 1.

(d) The fabricator shall establish the effective Code edi-tion, addenda and Code Cases for pressure vessels and re-placement parts in accordance with MandatoryAppendix 9.
