Заменен
Standard Test Method for Apparent Density of Rigid Cellular Plastics — 4 стр.
Значение и использование

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.
