1.1 This test method covers the determination of the ability of rubber to withstand the environmental effects of high humidity. This is accomplished by examination of the material after removal from the moisture-laden environment. It is designed for testing specimens of rubber materials cut from standard sheets prepared in accordance with Practice D3182.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 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. (For specific precautionary statements, see Note 1.)

1.4 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.

4.1 Rubber and rubber products for certain applications must withstand the environmental effect of high humidity and resist the deterioration of physical properties under these conditions with time. This test method allows performance properties to be determined under the accelerated conditions of high humidity and elevated temperature.

4.2 In view of climatic variations in service conditions, this method may not give results correlating exactly with service performance. However, the test method yields comparative data on which to base judgment as to service quality and it is useful in research and development work.

4.3 This test method is not applicable to coated fabrics; its use for materials other than rubber has not been established.
