This document specifies a test method for determining the resistance of vitreous and porcelain enamel coatings to abrasion by rubbing, grinding or other mechanical effects.

This document specifies two low voltage tests for detecting and locating defects that extend to the basis metal in vitreous and porcelain enamel coatings. Method A (electrical) is applicable to the rapid detection and determination of the general location of defects. Method B (optical), based on colour effects, is applicable to the more precise detection of defects and their exact locations. Both…

Le présent document spécifie deux essais à basse tension permettant de détecter et de localiser les défauts s'étendant jusqu'au métal de base sur les revêtements en émail vitrifié. La méthode A (électrique) s'applique à la détection rapide et la détermination de la localisation globale des défauts. La méthode B (optique), basée sur des effets de couleur, s'applique à la…
