Standard Guide for Abrasion Resistance of Textile Fabrics (Uniform Abrasion)

SCOPE
1.1 This guide covers the determination of the resistance to abrasion of a wide range of textile materials using the uniform abrasion testing instrument. Fabrics of all types including carpets, garments and nonwovens may be tested under this method.
Note 1-- Other procedures for measuring the abrasion resistance of textile fabrics are given in: Test Methods D3884, D3885, D3886, D4157, D4966, and AATCC Test Method 93.
1.1.1 Provisions are provided for testing specimens in dry and wet conditions. Four options for evaluation are included:
Option 1--Fabric RuptureOption 2--Mass LossOption 3-Thickness LossOption 4--Breaking Strength Loss
1.1.2 Provision is provided for testing specimens in the wet state.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as the standard. Within the text, the inch-pound units are shown in parentheses. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
1.3 This guide 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.

machine is used more extensively and a greater variety of
textiles have been tested. These anomalous results are fre-
quently very fruitful in the attainment of more durable and
satisfactory fabrics. As a rule they are not attributable to a
faulty operation of the testing machine or carelessness of the
operator. These results should not be discarded but should be
studied very intensively, for an understanding of the factors
which cause such anomalous results adds immeasurably to a
better understanding to this complex problem and to its more
intelligent application.
5.2 Test Method D 4158 for the determination of the abra-
sion resistance of textile fabrics, uniform abrasion method,
may be used for the acceptance testing of commercial ship-
ments of textile fabrics but caution is advised since technicians
may fail to get good agreement between results on certain
fabrics. Comparative tests as directed in 5.2.1 may be desir-
able.
5.2.1 In case of a dispute arising from differences in
reported test results when using Test Method D 4158 for
acceptance testing of commercial shipments, the purchaser and
the supplier should conduct comparative tests to determine if
there is a statistical bias between their laboratories. Competent
statistical assistance is recommended for the investigation of
bias. As a minimum, the two parties should take a group of test
