1.1 This practice presents a laboratory guide to determine the thermal resistance of loose-fill building insulations installed in side walls behind netting at mean temperatures between –10 and 35°C (14 to 95°F).
1.2 This practice applies to a wide variety of loose-fill thermal insulation products including fibrous glass, rock/slag wool, or cellulosic fiber materials and any other insulation material that can be installed pneumatically. It does not apply to products that change their character after installation either by chemical reaction or the application of binders, adhesives or other materials that are not used in the sample preparation described in this practice, nor does it consider the effects of structures, containments, facings, or air films.
1.3 Since this practice is designed for reproducible product comparison, it measures the thermal resistance of an insulation material which has been preconditioned to a relatively dry state. Consideration of changes of thermal performance of a hygroscopic insulation by sorption of water is beyond the scope of this practice.
1.4 The sample preparation techniques outlined in this practice do not cover the characterization of loose-fill materials intended for open applications.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 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.
1.7 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.
