ASTM D1622-03

Standard Test Method for Apparent Density of Rigid Cellular Plastics

SIGNIFICANCE AND USE
If the material to be tested includes forming skins, the apparent overall density, or the apparent core density, or both, shall be determined. If the material does not have forming skins, the term overall density is not applicable.  
This test method is also applicable to spray foam materials.  
Before proceeding with this test method, reference shall be made to the specification of the material being tested, if available. Any test specimen preparation, conditioning, dimensions, or testing parameters, or combination thereof, covered in the materials specification shall take precedence over those mentioned in this test method. If there are no material specifications, then the default conditions in this method apply.
SCOPE
1.1 The values stated in SI units are to be regarded as the standard. The values given in brackets are for information only.
1.2 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.
Note 1—ISO 845 is technically equivalent to this test method.
