ISO 14372:2011 specifies a method for the relative ranking, by 24 h exposure to humid air and subsequent diffusible hydrogen testing, of manual metal arc electrode coatings related to their tendency to absorb moisture. This test method has limited potential applicability since it is unlikely to be capable of being scaled up for large volumes of testing.

<p> La présente méthode d'essai est destinée à permettre une classification fiable des enrobages d'électrodes utilisés en soudage manuel à l'arc avec électrode enrobée, en enrobages standards (ST) ou résistant à l'humidité (MR), par une exposition de 24 h à l'air humide suivie d'une détermination de la teneur en hydrogène diffusible. </p>
