(Practice)Standard Practice for Conditioning Leather and Leather Products for Testing
Standard Practice for Conditioning Leather and Leather Products for Testing
SIGNIFICANCE AND USE
Temperature and relative humidity have an influence on many of the physical properties of leather. Depending on environmental conditions the moisture content in leather may vary significantly. Standardized conditioning in part allows for reliable comparisons to be made among different leather and leather products, and among different laboratories.
SCOPE
1.1 This practice covers the conditioning of all units and specimens of leather and leather products prior to testing and the conditions under which they should be tested. This practice does not apply to wet blue.
1.2 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.
