For additional precau-tionary statements, see Section 12.1.5 This standard does not purport to address all of thesafety con

8、cerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Materials and Manufacture6.1 Perlite is a generic term for a naturally occurringsiliceous mineral which is mined, crushed, sieved and dried toproduce a crude perlite ore. The crude ore, in the form

16、 ofparticles of varying size, weighing 60 to 75 lb/ft3(960 to 1200kg/m3), is expanded in high-temperature furnaces to densitiesin the range from 2.0 to 11.0 lb/ft3(32 to 176 kg/m3). As anaturally occurring mineral, it is classified as an elementarybuilding material. It is noncombustible as determine

17、d by TestMethod E136.7. Physical Requirements7.1 The physical requirements listed in this section aredefined as inspection requirements (see Practice C390). Theinsulation shall conform to the following requirements:Bulk density, lb/ft3(kg/m3) 211 (32176)Grading (particle size):Percentage retained, m

22、d flame under controlled condition, but does not byitself incorporate all factors required for fire risk assessment ofmaterials, products or assemblies under actual conditions.9.3.3 ProcedureHold a 0.02 to 0.03 lb (9 to 14g) speci-men of the perlite insulation in a suitable fixture (such as 6 by6 by
