1.1 These test methods are applicable to granular loose fill insulation materials such as vermiculite and perlite. They may be used for other insulation materials with similar flow and settling properties.

1.2 Method A will be used to determine bulk density.

1.3 Method B will be used to determine design density and, with Method A, can be used to calculate percent loss of volume due to settling.

1.4 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.


Method A will be used primarily as a manufacturing quality control and field test method without the need for conditioning. For more accurate research purposes, conditioning shall be specified.

Method B will be used, when specified, to determine the density at which insulation properties such as thermal resistance and placement coverage are to be determined.
