This document specifies a method for the estimation of the average grain size of copper and copper alloy products by ultrasound. This document can be applied for seamless round tubes as well as for flat products. This method can be used in place of test methods according to EN ISO 2624, mentioned in the relevant product standards. As reference method and in case of doubt the intercept procedure or planimetric procedure will be used.
