ASTM C 1104/C 1104M Standard Test Method for Determining the Water Vapor Sorption of Unfaced Mineral Fiber Insulation
ASTM C 1104/C 1104M 测定未覆面矿物纤维绝缘材料蒸汽吸收率标准试验方法
 
The sorption of water can result in an increase in weight and a resultant potential degradation of the properties of the insulation.

1. 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. Within the text, the inch-pound units are shown in parentheses. The values stated in each system are not exact equivalents, therefore, each system must be used independently of the other.
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.
