ASTM C1104/C1104M-13a Standard Test Method for Determining the Water Vapor Sorption of Unfaced Mineral Fiber InsulationASTM C1104/C1104M-13a 测定表面未加工的矿纤维绝缘材料水蒸气吸收性的试验方法1. ASTM C1104/C1104M标准适用范围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
