Standard Test Method for Determination of Abrasion and Smudge Resistance of Images Produced from Business Copy Products (Crockmeter Method)
1.1 This test method describes a procedure for determining the amount of image transferred onto the surface of a white cloth by rubbing.
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.
1.5 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.
