Paints and varnishes - Scratch test using a spring-loaded pen (ISO 22557:2019)

This document specifies a method for determining the resistance of a coating to scratches introduced by a usually hand-held loaded stylus.
The test can be carried out using a point stylus (method A) or using a disc stylus (method B).
Both methods are generally applicable and can be used in the field as well as on curved surfaces. Method A can also be applied on small test specimens (minimum dimensions 30 mm × 50 mm).
The test can be carried out as a "pass/fail" test (test requirement I) or as a classification test (test requirement II).

Peintures et vernis - Essai de rayage manuel avec un stylo d’essai de dureté (ISO 22557:2019)

Le présent document spécifie une méthode pour déterminer la résistance d'un revêtement aux rayures provoquées par un stylet, généralement portatif, sur lequel une charge est appliquée.
L'essai peut être réalisé avec un stylet à pointe (méthode A) ou un stylet à disque (méthode B).
Les deux méthodes sont généralement applicables, et il est possible de les utiliser sur le terrain ainsi que sur des surfaces courbes. La méthode A peut également être utilisée sur de petites éprouvettes (dimensions minimales: 30 mm × 50 mm).
L'essai peut être mis en œuvre sous la forme d'un essai de conformité/non-conformité (exigence d'essai I) ou d'un essai de classification (exigence d'essai II).
