ASTM D1044-24 PDF

1.1This test method describes a procedure for estimating the resistance of transparent plastics to one kind of surface abrasion by measuring the change in optical properties.

1.2Abrasive damage is numerically quantified by calculating the difference in haze percentage in accordance with Test Method D1003 between an abraded and unabraded specimen.

1.3The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

Note 1:This test method is equivalent in the measurement of resistance to abrasion of ISO 3537, Section 8 and ISO 15082, Section 11, but is not equivalent in any other measurement or section. This test method is not equivalent to ISO 9352, and results cannot be directly compared between the two methods.

Note 2:This test method is similar to SAE J3097 / ANSI Z26.1, Test 12.

Note 3:Prior attempts to employ the Taber Abraser for volume loss determinations of various plastics2 have been unsuccessful because of excessively large coefficients of variation attributed to the data. Insufficient agreement among the participating laboratories has rendered the use of volume loss procedure inadvisable as an ASTM test method.

Note 4:For determining the resistance to abrasion of organic coatings by weight loss, reference is made to Test Method D4060, which uses more aggressive CS-10 or CS-17 abrasive wheels.

1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
