4.5.2 Lot tests. In addition to the production tests specified (see 4.5.1), the compression load
deflection test specified (see 4.6.8) and the fuel retention test interval, whichever occurs first. The test
results shall be submitted to the qualifying activity for review.
4.5.2.1 Rejection and retest. Failure of any of the test specimens to conform to the applicable
requirements in see 3.6 and table I shall require a retest of the property which failed on an additional set
of test specimens from the same test section. Additional testing will be authorized by the qualifying
activity in order to isolate the extent of defective material. In the event of failure of any of the retested
specimens, the material represented by those specimens shall be rejected.
4.5.3 Process control tests. In addition to the production and lot tests, the following tests shall be
conducted on production material at 12-month intervals, and the results shall be forwarded to the
qualifying activity:
a. Tensile stress test (see 4.6.5)
b. Tear resistance test (see 4.6.6)
c. Fuel and water retention tests (see 4.6.10.1)
d. Flammability tests (see 4.6.11)
e. Volume swell in JP-4 for types IV and V (see 4.6.13)
f. Fluid immersion in JP-4 at 75°F (23.9°C) for 4 weeks (types IV and V) (see 4.6.17)
g. Hydrolytic stability tests for types I, II, and III at 160°F for 6 weeks (see 4.6.18)
h. Hydrolytic stability tests for type IV and V at 200°F for 6 weeks (see 4.6.18.1)
4.5.3.1 Process control samples and data. The following samples, if requested, and production data
shall be forwarded to the qualifying activity along with the process control test data:
a. Retention test specimens (4.6.10) and porosity (air pressure drop) test specimens (4.6.4).
b. Samples from the process control bun, size 20x20 inches by the bun height.
c. If requested, a copy of the production test data on all baffle material produced during the
previous 12 months.
