Downloaded from https://www.everyspec.com MIL-STD-2031 (SH) APPENDIX E LARGE SCALE PRESSURIZABLE FIRE TE!!T 10. SCOPE 10.1 Scope. This method describes a procedure to test materials in their intended application in a simulated submarine environment under a controlled laboratory fire exposure. The results from the test method shall be used to veriv material performance under the effects of an enclosed environment and relative location within the submarine. Tim test shall provide data for fire growth, smoke generation, and combustion product toxicity in a large-scale pressurized environment. The test data shall also be used to mnfirm small scale test results.

NPODS), 5801 Tabor Avenue, Philadelphia, PA 19120-5099.) 30. EQUIPMENT 30.1 Chamber. A large (10,000 cubic feet or greater) cylindrical chamber with hemispherical sections on the ends, capable of being pressurized to 618 kilopaseal (kPa) (897 lb/in2) and withstanding 230 (450 shall be used. The chamber shall be of sufficient diameter to allow mock-up of at least two separate levels of a submarine Figure 4 provides umfiguration and dimensions for the Naval Research Laboratory’s pressurizable chamber - Fn I. The chamber should have the following capabilities: a. A pressure rated access door at least 3 feet wide by 6 feet high to provide entry for reconfiguration materials and test materials
