ASTM C303-98

Standard Test Method for Dimensions and Density of Preformed Block and Broad-Type Thermal Insulation

SCOPE
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.
