Omutindo guno gukoleddwa okusinziira ku mutindo gw'Abachina oguliwo kati ogw'eddagala erikolebwa mu bikozesebwa mu kusaanuusa n'okulongoosa ekikomo n'ekikomo, kwe kugamba GB/T468-1997 "Copper Wire Ingots for Electrical Use", GB/T3952-1998 "Copper Wire Billets for Electrical Use", GB/T467-1997 "Obulongoofu bwa waggulu-." Cathode Copper" ne "Standard Cathode Copper", ne GB/T5231-2001 "Processed Copper and Copper Alloys" Okusinziira ku "Chemical Composition and Product Shape", omutindo gw'eggwanga ogwasooka GB/5121-1996 "Enkola z'okwekenneenya eddagala ku Copper ne Copper Alloys" ne GB/T13293-1991 "Chemical Enkola z'okwekenneenya ekikomo kya Cathode eky'obulongoofu obw'amaanyi" zaali erongooseddwa mu nkola. Obukodyo obw’omulembe obw’okwekenneenya butwalibwa okudda mu kifo ky’enkola z’okwekenneenya ez’obutwa n’ez’obulabe, era okukola hydride - non-dispersive atomic fluorescence spectrometry ekozesebwa okudda mu kifo kya catalytic oscillopolarography okuzuula arsenic, antimony, selenium, tellurium, n’ebirala Enkola empya musanvu ez’okwekenneenya zaakolebwa ne ziddamu okuwandiikibwa, omuli n’okufulumya atomu ya plasma eya inductively coupled enkola y’okwekenneenya spectrometry n’enkola y’okwekenneenya mercury, n’ebirala.
