ASTM D2322-10

Standard Test Method for Resistance of Shoe Upper Leather to Artificial Perspiration

SIGNIFICANCE AND USE
This test method gives an indication of the serviceability of shoe upper leather in actual wear.
SCOPE
1.1 This test method covers the determination of the effect of perspiration on shoe upper leather. The leather is subjected to treatment with a formulation of artificial perspiration specific for breakdown of leather. Resistance to grain cracking as measured in accordance with Test Method D2210 and area loss are used as the criterion of deterioration. The artificial perspiration may also affect the flexibility of the leather. However, these effects have not been fully evaluated as criteria of deterioration in this test method. 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 and health practices and determine the applicability of regulatory limitations prior to use.
