significance And Use:

scope:

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.

1.2 This guide involves blowing a sample of loose-fill insulation into a test frame of known volume, measuring the weight of the insulation captured and calculating the blown density.

1.3 This guide is intended for pneumatically-applied loose-fill mineral fiber insulation designed for use in horizontal open attic spaces.

1.4 This guide is intended for product design and product auditing by manufacturers of loose-fill insulation. This guide is adaptable as a plant quality control procedure.

1.5 This guide does not predict the aged density of the mineral fiber loose-fill insulation.

1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
