1.1 These test methods cover those insulation products in specified Specification C 208 that are not singularly specified elsewhere as insulating formboard (see Specification C 532) and nail-base sheathing (see Specification D 2277). The requirements for the products' physical properties are specified in Specification C 208. The methods for the general insulation products' physical properties are given as follows:

1.2 Reference is provided to an established source for nomenclature and definitions.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.4 Several of the test methods contained in this document are referenced by material specifications other than cellulosic fiber insulating board. These include mineral fiber, perlite, polyisocyanurate, polystyrene and phenolic materials.
