Over deze norm
1.1 This 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.
1.2 Abrasive damage is visually judged and numerically quantified by calculating the difference in haze percentage in accordance with Test Method D1003 between an abraded and unabraded specimen.
1.3 CS-10F wheels manufactured between October 2002 and September 2004 have been found to give different results than historical values. Comparisons of data using these wheels should be made with caution. Results using wheels made after September 2004 have agreed with those obtained before October 2002.
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
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.
