We have completed Kst testing in the 20-liter sphere for the dust samples identified as:

Sample No.

(Lab Marked) Identification Estimated Composition

1 DHDPS >95% Dihydroxy diphenyl sulfone

2 Veradel 3000 MP >95% Polyether sulfone-membrane grade

3 Veradel PESU >95% Polyether sulfone

The testing was performed as requested by Paul Higgins (FM Global/Chemical Ops.) on December 5, 2013.Thesample was not received until January 30, 2014.

The results of testing are summarized in Table 1. Table 2 lists the material properties of the dust sample. Table 3lists the results of any additional testing undertaken as a result of the initial testing or as requested, and Table 4lists the results of combustibility testing. A photograph of each sample is included in the Appendix.

Dust explosibility characteristics are very dependant on dust properties, such as particle size, moisture content anddust chemistry (i.e., what the dust is made of), so it is very important to be certain that past data are trulyrepresentative of current materials. If there are changes in the composition of the dust or the process by which it iscreated, retesting the dust is recommended.

Where results in this report are based on samples that have been sieved to remove particles larger than 500microns (rather than particles larger than 75 microns, i.e., fines only), a deflagration involving material with a higherpercentage of fines could be more severe than the test data indicate.

The samples were tested as less than 500 microns rather than fines only, as requested, since the sieve analysisindicated there were essentially no fines.

Standard Dust Tests

Kst TestingKst testing is performed in a 20-liter sphere using two 5 kJ chemical igniters. The test is performed in accordancewith ASTM E1226, which recommends that the dust sample consist of fines only (i.e., particles smaller than 75microns) and that the moisture content not exceed 5%. If the as-received sample has a moisture content greaterthan 5% it is dried to meet the test criteria. If as-received testing is requested on the request form, all particleslarger than 500 microns will normally be removed to approximate as-received testing. Kst testing can sometimes be

performed on dust samples with particles exceeding 500 microns by special arrangement with the lab.

Nst TestingNst is a nominal estimate of Kst, based on limited testing. The value of Nst can be used with DustCalc the same asKst, but one must bear in mind that the true Kst could actually be somewhat higher (because the Nst is only anestimate based on limited testing).

Screening TestingScreening testing is performed in a 20-liter sphere using two 5 kJ chemical igniters. This test is only a scan over abroad concentration range for explosibility and should not be used as vent design criteria. Concentrations used are1000, 2000 and 3000 g/m

3. The test is performed in accordance with ASTM E1226, which recommends that the

dust sample consist of fines only (i.e., particles smaller than 75 microns) and that the moisture content not exceed5%. If the as-received sample has moisture content greater than 5% it is dried to meet the test criteria. If as-received testing is requested on the request form, all particles larger than 500 microns will normally be removed toapproximate as-received testing. Screening testing can sometimes be performed on dust samples with particlesexceeding 500 microns by special arrangement with the lab.

OverdrivenOverdriven testing is performed when one of the following things occurs:

1. Testing is requested on the request form.2. Pmax is less than 4.0 bar.

Overdriven testing is performed in the 20-liter sphere at the most reactive concentration (i.e., concentration thatgave the maximum dP/dt during Kst testing), using one 5 kJ Sobbe igniter as the ignition source. If no reaction isobserved (dP/dt = 0 and Pm = 0), the sample can be considered overdriven. If the sample is found to beoverdriven, it can be considered hard to ignite.

Hard to IgniteHard-to-ignite testing is performed when one of the following things occurs:

1. Testing is requested on the request form.2. Minimum combustion time is longer than 80 milliseconds. 3. Pmax is less than 4.0 bar and the sample is not overdriven (see below).

Hard-to-ignite testing is performed in the 20-liter sphere at the most reactive concentration (i.e., the concentrationthat gave the maximum dP/dt during Kst testing) using four 100 J electric matches as the ignition source. If noreaction is observed (dP/dt = 0 and Pm = 0), the sample can be considered hard to ignite.

Minimum Explosible Concentration (MEC)Minimum explosible concentration testing is performed when requested on the request form. The testing isperformed in accordance with ASTM E1515 in the 20-liter sphere using one 5 kJ chemical igniter as the ignition

source.

CombustibilityThe sample is tested for combustibility by applying a match flame to a small mound of the sample. The reaction isobserved. Another mound of sample is then subjected to the flame of a propane torch. The reaction is againobserved.
