    ASTM D7255

    Significance and Use

    The resistance of leather to abrasion, as measured on a testing machine in the laboratory, is generally only one of several factors contributing to wear performance or durability as experienced in the actual use of the material. While abrasion resistance (often stated in terms of the number of abrasion cycles) and durability (defined as the ability to withstand deterioration or wear out in use, including the effects of abrasion) are frequently related, the relationship varies with different end uses and different factors may be necessary in any calculation of predicted durability from specific abrasion data. This test method provides a comparative ranking of material performance, which can be used as an indication of relative end-use performance.

    The resistance of leather to abrasion may be affected by factors including test conditions, type of abradant, pressure between the specimen and abradant, mounting or tension of the specimen, and type, kind, or amount of finishing materials.

    Abrasion tests utilizing the rotary platform, double-head tester may be subject to variation due to changes in the abradant during specific tests. Depending on abradant type and test specimen, the wheel surface may change (that is, become clogged) due to the pick up of finishing or other materials from test specimens and must be cleaned at regularly defined intervals.

    The measurement of the relative amount of abrasion may also be affected by the method of evaluation and may be influenced by the judgment of the operator.

    1. Scope

    1.1 This test method covers the determination of the abrasion resistance of leather using the rotary platform, double-head tester (RPDH).

    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 to determine the applicability of regulatory limitations prior to use.
