ASTM F2496-05(2011)e1

1.1 This practice describes procedures to obtain subjective, but comparative data for scratch hardness and scrape adhesion of coatings and color images produced by printers, copies and other reprographic devices.

1.2 This method simulates conditions where the surface of various substrates such as paper, film, cloth, and so forth may be subject to failure under mechanical force.

1.3 This test method covers the determination of the scratch hardness and scrape adhesion of coatings. Results are expressed in terms of force-to scratch coatings on substrates used in printing.

1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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.
