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:
