(Test Method)Standard Test Method for Measuring Thickness of Leather Units
Standard Test Method for Measuring Thickness of Leather Units
SIGNIFICANCE AND USE
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 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.
