ASTM D1813-13(2017)

Standard Test Method for Measuring Thickness of Leather Test Specimens

SIGNIFICANCE AND USE
3.1 This test method shall be used where precise dimensions are necessary for calculation of properties expressed in physical units. It is not intended to replace practical thickness measurements based on commercial portable tools, nor is it implied that thickness measurements made by the two procedures will agree exactly.
SCOPE
1.1 This test method covers the measurement of the thickness of leather test specimens in which the dimensions of the specimens are used directly in determining the results of tests for physical properties. This test method does not apply to wet blue.  
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.
