ASTM C520粒状疏松的填充隔热材料密度的标准试验方法

ASTM C520 Standard Test Methods for Density of Granular Loose Fill Insulations
ASTM C520 粒状疏松的填充隔热材料密度的标准试验方法

ASTM C520 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.
ASTM C520 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.

ASTM C520标准适用范围
1.1 These test methods are applicable to granular loose fill insulation materials such as vermiculite and perlite. They are used for other insulation materials with similar flow and settling properties.
1.2 Method A shall be used to determine bulk density.
1.3 Method B shall be used to determine design density and, with Method A, is 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.
