(Test Method)Standard Test Method for Abrasiveness of Ink-Impregnated Fabric Printer Ribbons and Other Web Materials
Standard Test Method for Abrasiveness of Ink-Impregnated Fabric Printer Ribbons and Other Web Materials
SIGNIFICANCE AND USE
This test method differentiates between web materials on the basis of their ability to cause wear on surfaces with which they come in contact. This test method can also be used to evaluate the wear resistance of different materials against such web materials.
SCOPE
1.1 This test method covers the determination of the abrasiveness of ink-impregnated fabric printer ribbons and other web materials by means of a sliding wear test.
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.

3.1 Definitions of Terms Specific to This Standard:
3.1.1 abrasive wear coeffıcient (for a ribbon)—a measure of the ability of the ribbon to wear surfaces with which it comes in
contact. The larger the value, the greater the ability to cause wear. The abrasive wear coefficient determined by this method is
directly proportional to the volume of material removed from the steel sphere in the test.
