Intshayelelo kwi
I-ETL sisishunqulelo seLebhu zoVavanyo loMbane. Ilabhoratri ye-ETL yasekwa ngumqambi waseMelika uThomas Edison ngo-1896 kwaye uyonwabela udumo oluphezulu e-United States nakwihlabathi jikelele.Njenge-UL kunye ne-CSA, i-ETL inokuvavanya kwaye ikhuphe uphawu lwesiqinisekiso se-ETL ngokwe-UL. umgangatho okanye wethu umgangatho wesizwe, kwaye inokuvavanya kwaye ikhuphe uphawu lwesiqinisekiso esiyintlanganisela ngokomgangatho we-UL okanye kuthi umgangatho wesizwe kunye nomgangatho weCSA okanye umgangatho waseKhanada. "Thina" kwicala elisezantsi lasekunene libonisa ukuba lisebenza eUnited States, " c" emazantsi ekhohlo ibonisa ukuba iyasebenza eKhanada, kwaye ukuba no "thina" kunye no "c" kuzo zombini ezi zizwe zisebenza kuwo omabini la mazwe.Nayiphi na imveliso yombane, oomatshini okanye i-electromechanical enophawu lwe-ETL ibonisa ukuba imveliso ihlangabezane neemfuno ezisezantsi zombane. imigangatho yokhuseleko lwemveliso eyaziwa ngokubanzi eUnited States naseKhanada kwaye ivavanyiwe ukuhlangabezana nemigangatho yokhuseleko lwemveliso efanelekileyo; kukwathetha ukuba umzi-mveliso uyavuma ukufumanaUkuhlolwa okungqongqo ngamaxesha athile ukuqinisekisa ukuhambelana komgangatho wemveliso, enokuthengiswa kuzo zombini eUnited States naseCanada.ETL ikwafuna ukuba iindawo zayo zokuvelisa ziye zahlolwa, kwaye umenzi-sicelo uyavuma ukwenza uhlolo olulandelelweyo lwamaxesha ngamaxesha. tyala emva koko ukuqinisekisa ukuba imveliso ihlala ihlangabezana nale mfuneko.
Inkqubo yesicelo sesiqinisekiso se-ETL
Okwangoku kukho iindlela ezimbini zesatifikethi se-ETL, olunye uhlobo lwengxelo yovavanyo lwe-CB, lunokuthi lufake isicelo ngokuthe ngqo ukungenisa amaxwebhu afunekayo ngolu hlobo lulandelayo: 1. Ifom yesicelo 2. Ikopi yesatifikethi sovavanyo lwe-CB (isicelo esithe ngqo asifuni) 3 Ifotokopi yengxelo yovavanyo lweCB (isicelo esithe ngqo akufuneki senze) 4. 5. Isampuli yezinye iziphumo zovavanyo ezifanelekileyo kunye nedatha yemveliso, njengeencwadana zemveliso, imifanekiso, uluhlu lwamacandelo, njalo njalo. lupasisiwe, uvavanyo lokungafani luya kufuneka)
Umxholo onxulumene nesatifikethi se-ETL
Isatifikethi se-ETL siyadingeka ukuze kuthunyelwe ngaphandle e-United States naseCanada.Uphawu lwe-ETL lubonisa ukuba imveliso iphumelele uvavanyo lokuvunywa kwe-NRTL e-United States kunye ne-SCC e-Canada.Intertek yenye yezigqeba ezimbalwa zokuqinisekisa eziqatshelwe yi-OSHA kunye ne-SCC. I-Shenzhen anbo inobudlelwane obusondeleyo ne-Intertek, enokunceda imveliso yakho ifumane isatifikethi se-ETL kwaye ibonelele ngeenkonzo ezibanzi.Uphawu lwe-ETL lulingana nophawu lwe-UL okanye lwe-CSA kwaye luyahlangabezana nemigangatho yokhuseleko efanelekileyo.Ukuba neflegi yekholamu ye-ETL yemveliso kuthetha ukuba ifikelele kwiimfuno ezincinci zemigangatho yokhuseleko lwemveliso.Ukongezelela, i-logo ye-ETL ikwabonisa ukuba indawo yokuvelisa umenzi ihlangabezana noluhlu oluthile lweemfuno ezisemgangathweni, kwaye iphonononga uphicotho oluthe gqolo lwefektri yokulandelela ukuqinisekisa ukuba consistency.ETL ibikho ngaphezu kwe-100. iminyaka.Iileta ezintathu ze-ETL zimfutshane kwiiLebhu zoVavanyo loMbane eyasekwa ngumqambi uMnu Edison ngo-1896.ETL imele izinto ezintsha, ezinempembelelo, ezizimeleyo.nt kwaye uvule uvavanyo lwemveliso kunye namava atyebileyo.Isiqinisekiso se-ETLus (thina kuphela, akukho c): isatifikethi se-cETL (kuphela c, akukho kuthi): isatifikethi se-cETlus (kuphela c, akukho kuthi): isatifikethi se-cETlus (kuphela c, akukho kuthi): cETlus isiqinisekiso (kuphela c, akukho kuthi) : isiqinisekiso se-cETlus (kuphela c, hayi thina)Ukuba unazo zombini, ufumana amaxesha ama-4 ngonyaka.
