Welding consumables. Determination of moisture resistance of manual metal arc welding electrodes by measurement of diffusible hydrogen1 Scope This International Standard 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.
