ASTM D8365-20

5.1?The procedure is primarily intended to evaluate corrosion produced by leather in contact with metals or metal objects that are used in construction and production of upholstery, briefcases, watches, jewelry, gun holsters, knife sheaths and any other circumstances where leather is in direct contact with various metal hardware and under circumstances where metal corrosion is a serious factor. A high relative humidity and increased temperature is used for the purpose of accelerating the results.

5.2?The relative corrosion severity rating system is provided in order to allow a numerical classification of the test results and to eliminate the necessity for elaborate weight loss measurements. Pitting corrosion, which is rated 4extensive (severe) corrosion, may involve only a negligible weight loss.

1.1?This test method covers the qualitative determination of corrosion produced by leather in contact with metal. This test method does not apply to wet blue or wet white.

1.2?The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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.

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.
