ASTM D1622 Standard Test Method for Apparent Density of Rigid Cellular Plastics

The ASTM D1622 standard covers the density of cellular plastic. Density can be evaluated as apparent overall density (includes creating skins) or pronounced core density (removing skins forming). This test method also applies to spray foam materials.

ASTM D1622 Standard Test Method for Apparent Density of Rigid Cellular Plastics

If the material to be tested contains forming coatings, the apparent overall density or the apparent core density, or both, is determined. If the material does not have forming coatings, the term general density does not apply.

Before proceeding with this test method, reference should be made to the specification of the material being tested. Any test specimen preparation, conditioning, size, or test parameter or combination covered in the applicable ASTM material specification shall take precedence over those specified in this test method. If there are no relevant ASTM material specifications, the default conditions in this method apply.

When density or apparent density is used to refer to a cellular plastic, it will be interpreted, without further qualification, as follows:

Density-to be interpreted as apparent overall density if the material is to be used with solid shaping skins.

If the density-forming skins are removed or removed before the material is used, it will be interpreted as the apparent core density.

Values ​​stated in SI units or inch-pound units should be considered separately as standard. The values ​​specified in each system may not be exactly equivalent; therefore, each system will be used independently of the other system. Combining values ​​from the two systems may result in non-compliance with the standard.

This standard is not meant to address all safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to determine appropriate safety and health practices prior to use and to determine the applicability of regulatory restrictions.
