ISO 21546-2019 涂料和清漆--用線(xiàn)性磨損試驗器(瓦罐計)測定耐磨擦性 Paints and varnishes — Determination of the resistance to rubbing using a linear abrasion tester (crockmeter)

This document specifies a method for determining the resistance of a coating to rubbing by means of a loaded abrasive material which is linearly moved over the surface to be tested.
The method can also be applied to different material surfaces, such as plastics and metals.st edition 2019-02 Paints and varnishes — Determination of the resistance to rubbing using a linear abrasion tester (crockmeter) Peintures et vernis — Détermination de la résistance à la rayure avec un abrasimètre linéaire Reference number ISO 21546:2019(E) ？ ISO 2019 ISO 21546:2019(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2019 All rights reserved.
