Dimensional measurements of various test specimens  are also required   by the specific test method. Density measurements of the product insulation  are useful in determining compliance of a product with specification limits,   and in providing a relative gage of product weights. For any one kind of  insulation,  some important physical and mechanical properties, such as thermal  conductivity,  heat capacity, strength, etc., bear a specific relationship  with its density. In order to design  for equipment supports, check the material for the x201C;as  received densityx201D; where the moisture content of the product as received  and then installed may consequential.1.1 This test method covers determination of the dimensions and density of block and board insulation as defined in Terminology C 168.1.2 The values stated in the SI system are to be regarded as the standard.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.【中国标准分类号】: Q25【国际标准分类号】: 91_100_60【页数】: 4P.;A4【正文语种】:
