5.1 Coating on substrates can be damaged by abrasion during manufacturing and service. This test method has been useful in evaluating the abrasion resistance of coatings. Ratings produced by this test method have correlated well with ratings produced by the falling abrasive values in Test Methods D968.
5.2 For some materials, abrasion tests utilizing the Taber Abraser may be subject to variation due to changes in the abrasive characteristics of the wheel during testing. Depending on abrading type and test specimen, the wheel surface may change (that is, become clogged) due to the adhesion of debris generated during the test and must be refaced at more frequent intervals as agreed upon by the interested parties. To determine if more frequent refacing is required, plot the total weight loss every 50 cycles. If a significant negative change in slope is observed prior to 500 cycles, the point at which the slope changes determines the refacing frequency.View Less
1.1 This test method covers the determination of the resistance of organic coatings to abrasion produced by the Taber Abraser on coatings applied to a plane, rigid surface, such as a metal panel.
1.2 The values stated in SI units are to be regarded as the standard, with the exception of mils when determining coating thickness.
1.3 This standard is similar in content (but not technically equivalent) to ISO 7784-2.
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.
