I-GB/T 222-2025 “Insimbi Nengxubevange - Ukuchezuka Okuvumelekile Ekuhlanganiseni Kwekhemikhali Kwemikhiqizo Eqediwe” kuzoqala ukusebenza ngomhla ka-1 Disemba 2025, esikhundleni samazinga wangaphambilini we-GB/T 222-2006 kanye ne-GB/T 25829-2010.
Okuqukethwe Okubalulekile Kwezinga
1. Ububanzi: Imboza ukuchezuka okuvumelekile ekwakhekeni kwamakhemikhali emikhiqizweni eqediwe (kuhlanganise namabhilidi) ensimbi engeyona ingxubevange, insimbi ye-alloy ephansi, insimbi yengxubevange,insimbi engagqwali, insimbi ekwazi ukumelana nokushisa, ama-alloys angakwazi ukugqwala, nama-alloys asezingeni eliphezulu.
2. Izinguquko Ezinkulu Kwezobuchwepheshe:
Izigaba ezingeziwe zokuchezuka kwesibabule okuvumelekile kwensimbi engeyona ingxubevange nensimbi ye-alloy ephansi.
Izigaba ezingeziwe zokuchezuka okuvumelekile kwesibabule, i-aluminium, i-nitrogen, ne-calcium kuzinsimbi ze-alloy.
Kungezwe ukuchezuka okuvumelekile kokwakheka kwamakhemikhali kuma-alloys aqinile amelana nokugqwala nama-alloys okushisa okuphezulu.
3. Uhlelo Lokuqalisa
