1/ Specimens of type IV cloth shall be 8 inches by 10 inches.
2/ Only one specimen shall be tested.
3/ Except that the specimen shall be observed for an additional 30 seconds after burner flame
turn off. If the tip of the flame passes beyond the top edge of the specimen at any time
during the 42 seconds after the burner is turned on, the specimen shall be reported as a test
failure. Five specimens shall be tested in the warp direction and the results reported
individually as "pass" or "fail".
4.4 Methods of inspection.
4.4.1 Breaking strength.
4.4.1.1 ASTM-D-5035 (1C-E or 1C-T).
4.4.1.2 The specimens shall be cut from each test sample unit at the same time as the
specimens for initial test and shall be marked to insure proper identification. The specimens
shall be subjected to the accelerated weathering procedure specified in 4.4.2. After
completion of the procedure, the two specimens shall be subjected to the following
conditions:
a. Two (2) hours at 180o + 5oF
b. 40 (+ 8) hours at 70 o + 2oF at a relative humidity of 65 +2%.
Each specimen shall then be tested for breaking strength as specified in 4.4.1.1.
