ИСО 12137-2-1997 “Определение устойчивости красок и лаков к царапанию. – Часть 2: Способ рисования игл с заостренным кончиком”

ИСО 12137:2011 specifies a method for determining the abrasion resistance of a single coating or the upper layer of a multi-layer system of paint, varnish or related products using a curved (annular or ring-shaped) зонд. The test has been found to be useful in comparing the abrasion resistance of different coatings. It is useful for offering a range of coated panels that exhibit significant differences in abrasion resistance. ИСО 12137 does not specify a method for using a pointed pen; two are specified in ISO 1528-1 и ИСО 1528-2, соответственно. The choice between the three approaches will depend on the particular practical problem.
