1. Ukuqalisa
I-TUV Certification Aluminium Foil imele ukuhlangana okubalulekile kwekhwalithi yezinto, isiqiniseko sokuphepha, kanye nokuthobela imithetho ekukhiqizeni kwesimanje.
I-aluminium foil yinto esetshenziswa yonke indawo ukupakisha ukudla, Amakhemikhali, izimoto, Ama-Electronics, kanye nokufakwa kwezimboni.
Ngenkathi i-aluminium ngokwayo ingenawo amakhemikhali futhi iyisivimbelo esihle kakhulu, yayo ukusebenza ekugcineni kwezinhlelo zokusebenza kuncike ekukhethweni kwe-alloy, ukujiya, ukuphela kwendawo, nokulawula amaphutha.
Ngenani eliphezulu, ukuphepha-okubalulekile, noma izimakethe zokuthekelisa, isitifiketi somuntu wesithathu iba yinto esemqoka.
Isitifiketi se-TUV sinikeza ukuqinisekiswa okuzimele kokuthi umkhiqizo we-aluminium foil uhlangabezana nekhwalithi eqinile nemibandela yokulawula..
Iqinisekisa abathengi, abalawuli, kanye nabasebenzisi bokugcina ukuthi impahla iyini ezinokwethenjelwa ngomshini, iphephile ukusetshenziswa okuhlosiwe, futhi ithobela izindinganiso zemvelo nezamazwe ngamazwe.
2. Yini i-TUV Certification?
Isizinda Somlando kanye Nobukhona Bomhlaba
I-TUV, short for Inhlangano Yokuhlola Ubuchwepheshe (Inhlangano Yokuhlola Ubuchwepheshe), yasungulwa ngo 1872 eJalimane ukuqinisekisa ukuphepha kuma-boilers we-steam kanye nokusebenza kwezimboni.
Namuhla, I-TUV isebenza njenge-a ukuhlolwa okwaziwa emhlabeni wonke, ukuhlola, kanye nesiphathimandla sokunikeza izitifiketi, namagatsha eYurophu, E-Asia, kanye naseNyakatho Melika.
Izitifiketi zayo zibonwa ku:
- iyuniyani yase-Europe (Ukuhambisana ne-CE, Umthetho wokuxhumana nokudla kwe-EU)
- I-united states (Ukuhambisana ne-FDA, Izindinganiso ze-ASTM)
- E-Asia (I-CCC yaseChina, Japan JIS ukuqashelwa)
Ukuba khona komhlaba wonke kwe-TUV kuqinisekisa ukuthi i-aluminium foil eqinisekisiwe ingahlangana izidingo zokulawula zamazwe ngamazwe, ukunciphisa izinqubo zokungenisa/ukuthekelisa kanye nokuthuthukisa ukwamukelwa kwemakethe.
Izimiso Eziyinhloko Zesitifiketi se-TUV
- Ukungakhethi: Ukuhlola okuzimele nokungachemi, mahhala ethonyeni lomkhiqizi.
- Ukuqina: Ukuhlolwa nokuhlolwa kwamabhuku kulandela imigomo eqinile, nemikhawulo eqinisekiswe ngokwesayensi.
- Ukucaca: Qedela ukubika, imibhalo elandelekayo, kanye nokuxhumana okucacile kwemiphumela.
Lezi zimiso ziqinisekisa ukuthi Isitifiketi se-TUV sinjalo ethembekile futhi ethenjwa kabanzi ezimbonini lapho ikhwalithi nokuphepha kungeke kube sengozini.
