(Test Method)Standard Test Method for Determination of Resistance of Leather to (Bleeding) Color Stain Transfer
Standard Test Method for Determination of Resistance of Leather to (Bleeding) Color Stain Transfer
SIGNIFICANCE AND USE
4.1 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 method2 covers the determination of whether leather bleeds (exudes coloring matter) when in intimate contact with wet surfaces, as indicated by staining produced on wet cloth in contact with the leather. 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.
