ASTM C303 – Standard Test Method for Dimensions and Density of Preformed Block and Board–Type Thermal Insulation
Description:
Significance and Use
5.1 Dimensional measurements of the product thermal insulation are essential in determining compliance of a product with specification limits. Dimensional measurements of various test specimens are also required by the specific test method.
5.2 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 “as received density” where the moisture content of the product as received and then installed has the potential to be consequential.
Scope
1.1 This test method covers determination of the dimensions and density of block and board insulation as defined in Terminology C168.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
