Historical (view previous versions of standard)
Significance and Use
4.2 Thermal resistance (and conductivity) of loose-fill mineral fiber insulation depends on density and thickness. The resulting blown density data is useful in developing an expression for apparent thermal conductivity as a function of density. This will in turn aid the manufacturer in developing coverage information for packages of loose-fill insulation.
4.3 The blown density obtained in this method is for the thickness of the test only. The relationship of blown density with thickness can be determined by repeating the procedures outlined here using different thicknesses.
4.4 These procedures are not the same as the test method described in Test Method C1374. Depending on the test conditions utilized, the blown density may, or may not, represent the installed density values obtained by using Test Method C1374.
1.1 This guide describes two alternate procedures for determining blown density at a predetermined thickness or a range of thicknesses expected in field applications of mineral fiber loose-fill insulation.
1.6 This standard does not purport to address all 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 to determine the applicability of regulatory limitations prior to use.
