This test method describes a procedure for determining the amount of image transferred onto the surface of a white cloth by rubbing.
Formerly under the jurisdiction of Committee F05 on Business Imaging Products, this test method was withdrawn in January 2020 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
1.2 The test method can be employed to evaluate the abrasion and smudge resistance of business imaging products produced by impact printers, thermal transfer printers, and non-impact printers or copiers.
1.3 The test method can be used to evaluate the amount of material removed from the sample (smudge or crock). Testing focuses on determining the amount of material deposited on the crockmeter cloth or redeposited in a new location on the sample. The test method can also be employed to measure performance characteristics for a product. The user should select test equipment which is appropriate for measuring the abrasion to the samples. Samples are tested before and after rubbing and comparisons of results made. In this test method product performance evaluations are optional.
1.4 Other test methods employing the Sutherland rub tester, Taber Abrader and Gavarti GA-C.A.T. can be employed to evaluate the smudge and abrasion characteristics. Results by these units are not necessarily equivalent to those obtained with the Crockmeter.
