20、ectrometry methods (A to F) for the determination of alloying elements and impurities in copper and copper alloys in the form of unwrought, wrought and cast products. A complementary method, for the analysis of Copper-tin-lead alloys, is described in Annex B (informative). The precision criteria con
21、cerning this method do not reach the suitable level, for all the elements specified (zinc and phosphorus, namely).
