Umgangatho weSizwe waseTshayina i-GB/T 222-2025: “Intsimbi kunye nee-Alloys – Ukuphambuka okuvumelekileyo kwiMichiza yeeMveliso eziGqityiweyo” kuza kuqala ukusebenza ngoDisemba 1, 2025.

I-GB/T 222-2025 ethi “Intsimbi kunye nee-Alloys - Ukuphambuka okuVumelekileyo kwiMichiza yeeMveliso eziGqityiweyo” iza kuqala ukusebenza ngomhla woku-1 kweyoMnga, 2025, ithatha indawo yemigangatho yangaphambili ye-GB/T 222-2006 kunye ne-GB/T 25829-2010.

Umxholo oPhambili woMgangatho
1. Ububanzi: Bugubungela ukuphambuka okuvumelekileyo kwimilo yeekhemikhali kwiimveliso ezigqityiweyo (kuquka iibhilethi) zentsimbi engeyiyo i-alloy, intsimbi engaphantsi kwe-alloy, intsimbi ye-alloy,yenziwe ngentsimbi eshayinayo, intsimbi engatshisiyo, ii-alloys eziguquguqukayo ezingamelani nokugqwala, kunye nee-alloys ezishushu kakhulu.

 
2. Utshintsho Olukhulu Lobuchwephesha:
Ukongezwa kohlulo lokuphambuka kwesalfure okuvumelekileyo kwintsimbi engeyiyo i-alloy kunye nentsimbi engaphantsi kwe-alloy.
Ukongezwa kohlulo lokuphambuka okuvumelekileyo kwesalfure, ialuminiyam, initrogen, kunye necalcium kwiintsimbi zealloy.
Kongezwe ukuphambuka okuvumelekileyo kokwakheka kweekhemikhali kwii-alloys eziqinileyo zokugqwala kunye nee-alloys ezishushu kakhulu.

3. Ishedyuli yokuphunyezwa
