Standard Test Method for Resistance of Colored Leather to Bleeding
SIGNIFICANCE AND USE
Bleed resistance is considered to be an important characteristic in leather used to make lined and unlined items that may come in contact with water.
SCOPE
1.1 This test method covers the determination of the resistance of colored leather to bleeding. This test method does not apply to wet blue.
1.2 This test method is intended for use on finished upper leather for shoes or similar end use, or the leather article such as shoe, handbag, etc.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 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.
