▍Siyini Isitifiketi se-TISI?
I-TISI ifushane nge-Thai Industrial Standards Institute, exhumene noMnyango Wezimboni waseThailand. I-TISI inomthwalo wemfanelo wokwenza amazinga asekhaya kanye nokubamba iqhaza ekwakhiweni kwamazinga omhlaba kanye nokwengamela imikhiqizo kanye nenqubo yokuhlola efanelekayo ukuze kuqinisekiswe ukuthotshelwa okujwayelekile nokuqashelwa. I-TISI yinhlangano egunyazwe uhulumeni elawulayo yesitifiketi esiyimpoqo e-Thailand. Futhi inomthwalo wemfanelo wokwakhiwa nokuphathwa kwamazinga, ukugunyazwa kwelebhu, ukuqeqeshwa kwabasebenzi nokubhaliswa kwemikhiqizo. Kuyaphawulwa ukuthi awukho umgwamanda wokunikeza izitifiketi oyimpoqo ongekho ngaphansi kukahulumeni e-Thailand.
Kunesitifiketi sokuzithandela nesiyimpoqo eThailand. Amalogo e-TISI (bona uMdwebo 1 no-2) avunyelwe ukusetshenziswa lapho imikhiqizo ihlangabezana nezindinganiso. Emikhiqizweni engakamiswa, i-TISI iphinde isebenzise ukubhaliswa komkhiqizo njengendlela yesikhashana yokuqinisekisa.
▍ Ububanzi Bokugunyazwa Okuphoqelekile
Isitifiketi esiyimpoqo sihlanganisa izigaba eziyi-107, izinkambu eziyi-10, okuhlanganisa: izinto zikagesi, izesekeli, okokwelashwa, izinto zokwakha, izimpahla zabathengi, izimoto, amapayipi e-PVC, iziqukathi zegesi ye-LPG kanye nemikhiqizo yezolimo. Imikhiqizo engaphezulu kwalo mkhakha iwela ngaphakathi kwesikhala sokuzithandela sokuthola izitifiketi. Ibhethri iwumkhiqizo wesitifiketi oyimpoqo esitifiketini se-TISI.
Izinga elisetshenzisiwe:I-TIS 2217-2548 (2005)
Amabhethri asetshenzisiwe:Amaseli esibili namabhethri (aqukethe i-alkaline noma amanye ama-electrolyte angewona ama-asidi - izimfuneko zokuphepha zamaseli esibili avaliwe, namabhethri enziwe ngawo, ukuze asetshenziswe ezinhlelweni eziphathwayo)
Igunya lokukhishwa kwelayisensi:I-Thai Industrial Standards Institute
▍Kungani i-MCM?
● I-MCM ibambisana nezinhlangano zokuhlolwa kwemboni, ilabhorethri kanye ne-TISI ngokuqondile, ekwazi ukunikeza isisombululo esingcono kakhulu sokunikeza izitifiketi kumakhasimende.
● I-MCM inesipiliyoni seminyaka engu-10 esichichimayo embonini yebhethri, ekwazi ukuhlinzeka ngosekelo lobuchwepheshe oluchwepheshile.
● I-MCM inikeza isevisi yenqwaba yesitobhi esisodwa ukuze isize amakhasimende angene ezimakethe eziningi (hhayi kuphela i-Thailand efakiwe) ngempumelelo ngenqubo elula.
UL 1973:2022 yashicilelwa ngomhla zingama-25 kuNhlolanja. Le nguqulo isekelwe kokusalungiswa kweziphakamiso ezimbili ezikhishwe ngoMeyi nango-Okthoba ka-2021. Izinga elishintshiwe landisa ububanzi balo, okuhlanganisa umsizi wesistimu yamandla wemoto (isb. ukukhanya nokuxhumana). Faka okuthi 7.7 Transformer: i-transformer yesistimu yebhethri izogunyazwa ngaphansi kwe-UL 1562 futhi UL 1310 noma amazinga afanelekile. Amandla kagesi aphansi angagunyazwa ngaphansi kuka-26.6. Isibuyekezo 7.9: Izifunda Ezivikelayo Nokulawula: isistimu yebhethri izohlinzeka ngeswishi noma i-breaker, ubuncane bayo obudingekayo ukuze kube ngu-60V esikhundleni sika-50V. Isidingo esingeziwe somyalelo we-overcurrent fuse.
Faka Okungu-18 Okugcwele Okuchichimayo Ngaphansi Kokukhishwa: Hlola ikhono lesistimu yebhethri ngokulayishwa ngokweqile ngaphansi kokukhipha. Kunezimo ezimbili zokuhlolwa: eyokuqala igcwele ngokweqile ngaphansi kokukhipha lapho igagasi liphakeme kunesilinganiso esiphezulu samanje sokukhipha amanzi kodwa siphansi kunokwamanje sokuvikela okudlulele kwe-BMS; eyesibili iphakeme kune-BMS ngaphezu kokuvikela kwamanje kodwa iphansi kuneleveli 1 yamanje yokuvikela.
