ASTM C1104/C1104M-19

Standard Test Method for Determining the Water Vapor Sorption of Unfaced Mineral Fiber Insulation

SIGNIFICANCE AND USE
5.1 The sorption of water can result in an increase in weight and a resultant potential degradation of the properties of the insulation.
SCOPE
1.1 This test method covers the determination of the amount of water vapor sorbed by mineral fiber insulation exposed to a high-humidity atmosphere. This test method is applicable only to fibrous base material and binder. The results obtained by this test method cannot be used in describing faced products, since the facing is not tested by using this test method.  
1.2 The water vapor sorption characteristics of materials may be affected by conditions such as elevated temperatures or chemical exposures. Values obtained as a result of this test method may not adequately describe the water vapor sorption characteristics of materials subjected to these conditions.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 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.

3.1 Definitions of Terms Specific to This Standard:
3.1.1 The term sorption has been adopted for this test method, since mineral fiber insulation may absorb water within its bulk
when viewed macroscopically, while it adsorbs water onto individual fibers on a microscopic scale.
(1) sorption—refers to the taking up and holding of matter by other matter by various processes such as absorption and
adsorption.
(2) absorption—refers to the taking up of matter in-bulk by other matter; for example, the penetration of substances into the
bulk of another solid or liquid.
(3) adsorption—refers to surface retention or adhesion of an extremely thin layer of molecules to the surfaces of solids or
liquids with which they are in contact.
