Description / Abstract:
This International Standard specifies a method for determining,
using a curved (loop-shaped or ring-shaped) stylus, the mar
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 mar
resistance of different coatings. It is most useful in providing
relative ratings for a series of coated panels exhibiting
significant differences in mar resistance.
This International Standard does not specify a method using a
pointed stylus, two of which are specified in ISO 1518-1 and ISO
1518-2, respectively. The choice between the three methods will
depend on the particular practical problem.
