: The method typically utilizes a smoke density chamber (NBS Smoke Chamber) where a specimen is exposed to a radiant heat source, often in both flaming and non-flaming modes. ADS-13 Connection : The "13" in your query may refer to Aeronautical Design Standard ADS-13
. This standard was primarily used to measure the smoke-obscuring properties of solid materials used in aircraft interiors when they burn or smolder.
: This standard was eventually withdrawn by ASTM without a direct replacement, as the industry shifted toward astm f814 83 pdf 13
, which mandates fire protection standards for compartment interiors. Test Apparatus
: It provides a laboratory procedure for determining the specific optical density of smoke generated by solid aerospace materials and assemblies, including insulated wire, in thicknesses up to 1 inch (25.4 mm). Application : The method typically utilizes a smoke density
Пожаровзрывобезопасность/Fire and Explosion Safety Key Details of ASTM F814
, which is the standard test method for specific optical density of smoke generated by solid materials. : This standard was eventually withdrawn by ASTM
Пожаровзрывобезопасность/Fire and Explosion Safety Related Technical Context Aviation Regulations : This test method is closely tied to Federal Aviation Regulation (FAR) 25.853
