Bojra dhe llaqe - Përcaktimi i qëndrueshmërisë së gërvishtjes - Pjesa 2: Metoda e ngarkesës së ndryshueshme (ISO 1518-2:2011)

Paints and varnishes - Determination of scratch resistance - Part 2: Variable-loading method (ISO 1518-2:2011)

Scope

ISO 1518-2:2011 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.
Neither ISO 1518-1 nor ISO 1518-2 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.
