ASTM D1814 – Standard Test Method for Measuring Thickness of Leather Units
Description:
Significance and Use
4.1 This test method is designed for the routine measurement of the thickness of leather units as a means of production control and determining conformance to specifications. It utilizes a secondary type of gage that is capable of rapid measurement.
Scope
1.1 This test method covers the measurement of the thickness of units of all types of leather. It is not suitable for measuring the thickness of test specimens.
1.2 The thickness of leather units may be reported in millimetres, ounces, or irons. Ounces are generally used when referring to the thickness of shoe upper leather. Irons are generally used when referring to the thickness of sole leather. (One ounce equals 1/64 in. or 0.0156 in. or 0.396 mm. One iron equals 1/48 in. or 0.0208 in. or 0.53 mm.)
1.3 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.
