This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

1. Scope
1.1 Thistestmethodcoversthedeterminationoftheamountofwaterabsorbedbyleatherat23 62°Cbyimmersionunderstatic
conditions. It may be used on all types of leather. This test method does not apply to wet blue.
1.2
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.

2.1 ASTM Standards:
D1517 Terminology Relating to Leather
D1610 Practice for Conditioning Leather and Leather Products for Testing
3. Terminology
3.1 For definitions of leather terms used in this test method refer to Terminology D1517.
4. Summary of Test Method
4.1 In this test method the amount of water absorbed by a leather specimen is measured at room temperature with all surfaces
exposed to water.
5. Significance and Use
5.1 This test method is used to determine compliance with specifications for water absorption of upper leather. The significance
of the test method is limited by the static conditions employed, and the results do not reflect the water absorption under dynamic
conditions of flexing.
6. Apparatus
6.1 Beaker, 1000 mL.
6.2 Balance, sensitive to 0.01 g.

6.3 Blotting Paper .
7. Test Specimen
7.1 The test specimen shall be a square of leather approximately 4 by 4 in. (102 by 102 mm).
7.2 Unless otherwise specified in the detail specification, one specimen from each test unit of sample shall be tested.
7.3 Prior to testing, the specimen shall be conditioned according to Practice D1610.

8. Procedure
8.1 Weigh the specimen to the nearest 0.01 g and record the mass as W .
1
8.2 One to three specimens shall be completely immersed in a 1000 mL beaker of distilled water at 23°C 6 2°C. This should
be done in such a manner that the surface of the specimens do not touch each other.
8.3 After 1 h 61 min immersion, the specimens shall be removed from the beaker and the surface water from each removed
by lightly blotting the specimen with blotting paper prior to weighing.
8.4The specimen shall then be weighed immediately and the mass recorded as
8.4 Blotting paper that has been cut to the same size as the leather test specimen shall be used. A 4 by 4 in. (102 by 102 mm)
non-water absorbing, rigid flat plate shall be placed on a level surface. Two died squares of blotting paper shall be stacked upon
the rigid flat plate. One test specimen shall be removed from the container and placed, grain up on top of the blotting squares. Two
more blotting paper squares shall be placed upon the first specimen. A second specimen shall be removed from the container an
