This document specifies a method for determining@ using a pointed stylus loaded with a continuously increasing load@ the scratch resistance of a single coating of a paint@ varnish or related product@ or the upper layer of a multicoat system. This test has been found to be useful in comparing the scratch resistance of different coatings. It is most useful in providing relative ratings for a series of coated panels exhibiting significant differences in scratch resistance. NOTE Neither this document nor ISO 1518?1 specifies a method using a curved stylus@ which is specified in ISO 12137. The choice between the three methods will depend on the particular practical problem.
