Downloaded from https://www.everyspec.com . . MI I.-STD-2O3I(SH) 40.S Test data. The test di~ti] l’rorn the eight TCS shall bc recrmicd as a continuous function of time. 50. 50.1 Report contents. Test repot-ls shall include lhc following: a. Sufficient nomenclature and code markings to identi& the material evaluated and the manufacturer b. Time to smoke or fire gases (if they occur) are evolved from the non-fire side of the material specimen c. Time to burn-through material test specimen as evident by flame on the non-fire side. If bum-through does not occur within the 60 minutes, the time shall be reported as “>60 minutesH. d.

The time that the material specimen continues to burn on either side following removal of lhe propane burner source e. Tabular and graphic representations of the temperature profiles in 5 minute intetvals for the three vertically mounted TCS and the TC mounted behind the center mounted TC. The temperature profile shall be recorded continuously and include temperatures during the test and for a period of 1 hour after the burner is removed f. Smoke generation (initial occurrence, amount+ color,. etc.) g. Visual inspection of fire damage to include any swelling, contraction, cracking, bulging, melting or dripping, separation of plies and effective material thickness remaining h.

Visual record shall be obtained, for example video camera, to record the test set-up before starting the test, light-off of the propane burner with flame impingement on the material specimen, significant material destruction or fire gases on the fire side, and initial bum-through of the material specimen. 19
