Significance and Use | ||||||||||||||||||||
5.1 Coatings, particularly the high gloss coatings used on automobiles, boats, toys, etc., are subject to a wide variety of conditions (for example, wiping, cleaning, and exposure) that can mar their surface. The ability of these coatings to maintain their appearance is an important product attribute. These test methods provide a way to estimate the ability of high gloss coatings to resist mar damage. 5.2 These test methods do not provide fundamental values. However they are suitable for estimating the ability of high gloss coatings to resist mar. 5.3 Since the susceptibility of coatings to marring varies widely, the number of cycles that are needed to cause “relevant” mar damage also varies. Usually, 2 to 50 cycles are sufficient. |

1. Scope | ||||||||||||||||||||
1.1 This test method covers procedures for evaluating the relative mar resistance of high gloss coatings. Two test methods are included. Test Method A uses a device that contains a rotating specimen holder and two abrasive wheels. Test Method B uses a device that contains a reciprocating specimen holder and a single wheel that has been fitted with abrasive paper. Either method can be used to evaluate the dry abrasion mar resistance of coatings applied to planar, rigid surfaces. Each test method provides good discrimination between highly mar resistant coatings. 1.2 The values stated in SI units
are to be regarded as standard. No other units of measurement are
included in this standard.
1.3 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. |
