METHODS OF TEST FOR PAINTS AND VARNISHES : PART E17 : DETERMINATION OF MAR RESISTANCE USING A CURVED STYLUS (ISO 12137-1:1997)
1.1 This part of Malaysian Standard is one of a series of standards dealing with the
sampling and testing of paints, varnishes and related products.
It 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
multi coat system. MS 133 : Part E18 specifies a method using a pointed stylus. The choice
between the two methods will depend on the particular practical problem.
1.2 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
