Lo mgangatho uqulunqwe ngokuhambelana nemigangatho yangoku yaseTshayina yokwakhiwa kweekhemikhali zobhedu kunye nobhedu lwe-alloy yokunyibilikisa kunye neemveliso zokucubungula, ezizezi, i-GB/T468 - ngo-1997 "Iingots ze-Copper Wire zokusetyenziswa koMbane", GB/T3952{7}}1998 "Iibhilithi zocingo lwe-Copper zokusetyenziswa koMbane", i-GB/T4 "Ucoceko oluphezulu{10}} lweCathode Copper" kunye ne "Standard Cathode Copper", kunye ne-GB/T5231-2001 "I-Copper esetyenziweyo kunye ne-Copper Alloys" Ngokusekelwe kwi-"Chemical Composition and Product Shape", imigangatho yesizwe yokuqala ye-GB/5121-1996 "IiNdlela zokuHlalutya kweMichiza/-Iindlela ze-Alloys 319 zeCopper kunye ne-T19 ye-Alloys ye-319 ye-GB kunye ne-T19 ye-Alloys 19 GB "IiNdlela zokuHlalutywa kweMichiza kwi-High-Purity Cathode Copper" zahlaziywa ngokucwangcisiweyo. Iindlela zokuhlalutya eziphucukileyo ziyamkelwa ukuba zithathe indawo yeendlela zokuhlalutya eziyityhefu neziyingozi, kunye nokuveliswa kwehydride - i-non-dispersive atomic fluorescence spectrometry isetyenziselwa ukutshintsha i-oscillopolarography ye-catalytic yokumisela i-arsenic, i-antimony, i-selenium, i-tellurium, njl. indlela yokuhlalutya kunye nendlela yohlalutyo lwe-mercury, njl.
