Standar iki dirumusake miturut standar Cina saiki kanggo komposisi kimia produk peleburan lan pangolahan paduan tembaga lan tembaga, yaiku GB/T468-1997 "Copper Wire Ingots for Electrical Use", GB/T3952-1998 "Copper Wire Billets for Electrical Use", GB/T467{9}}}19{9}}} Cathode Copper" lan "Standard Cathode Copper", lan GB/T5231-2001 "Processed Copper and Copper Alloys" Adhedhasar "Chemical Composition and Product Shape", standar nasional asli GB/5121-1996 "Chemical Analysis Methods for Copper and Copper Alloys" lan GB/T1999 Methods Higherity. Cathode Copper" direvisi kanthi sistematis. Techniques analitis majeng diadopsi kanggo ngganti cara analitis beracun lan mbebayani, lan generasi hidrida - non-dispersive spektrometri fluoresensi atom digunakake kanggo ngganti oscillopolarography katalitik kanggo netepake arsenik, antimon, selenium, tellurium, etc. metode, lsp.
