Isingeniso ku
I-ETL isifinyezo se-Electrical Testing Laboratories.Ilabhorethri ye-ETL yasungulwa umsunguli waseMelika u-Thomas Edison ngo-1896 futhi ijabulela idumela eliphezulu e-United States nasemhlabeni.Njenge-UL ne-CSA, i-ETL ingahlola futhi ikhiphe umaki wesitifiketi se-ETL ngokuya nge-UL. izinga elijwayelekile noma lethu likazwelonke, futhi lingahlola futhi likhiphe uphawu lwesitifiketi esiyinhlanganisela ngokwezinga le-UL noma izinga lethu likazwelonke kanye nezinga le-CSA noma izinga laseCanada. Igama elithi "thina" elingezansi kwesokudla libonisa ukuthi lisebenza e-United States, " c" kwesokunxele esingezansi kukhombisa ukuthi sisebenza e-Canada, futhi ukuba no-"thina" kanye no-"c" kusebenza kuwo womabili la mazwe. Noma yimuphi umkhiqizo kagesi, womshini noma ngomshini womshini onophawu lwe-ETL ubonisa ukuthi umkhiqizo uhlangabezane nezimfuneko eziphansi ze- amazinga ajwayelekile okuphepha komkhiqizo e-United States nase-Canada futhi ahlolelwe ukuhlangabezana namazinga afanele okuphepha komkhiqizo; futhi kusho ukuthi imboni yokukhiqiza iyavuma ukwamukelaukuhlolwa ngezikhathi ezithile okuqinile ukuze kuqinisekiswe ukuhambisana kwekhwalithi yomkhiqizo, ongathengiswa kokubili e-United States nase-Canada.I-ETL idinga futhi ukuthi iziza zayo zokukhiqiza zihlolwe, futhi umfakisicelo uyavuma ukwenza ukuhlolwa kokulandelela ngezikhathi ezithile kwawo. tshala emva kwalokho ukuze uqinisekise ukuthi umkhiqizo uhlala uhlangabezana nale mfuneko.
Inqubo yokufaka isicelo sesitifiketi se-ETL
Njengamanje kunezindlela ezimbili zesitifiketi se-ETL, uhlobo olulodwa kungombiko wokuhlolwa kwe-CB, futhi angafaka isicelo ngokuqondile ekuletheni imibhalo edingekayo zimi kanje: 1. Ifomu lesicelo 2. Ikhophi yesitifiketi sokuhlola se-CB (isicelo esiqondile asidingi) 3 Ikhophi yombiko wokuhlolwa we-CB (ukusebenza okuqondile akudingeki) 4. 5. Isampula yeminye imiphumela yokuhlolwa efanele kanye nedatha yomkhiqizo, njengamamanuwali omkhiqizo, izithombe, uhlu lwezingxenye, nokunye.(uma umbiko we-CB kuphumelele, ukuhlolwa kokungafani kuzodingeka)
Okuqukethwe okuhlobene nesitifiketi se-ETL
Isitifiketi se-ETL siyadingeka ukuze kuthekeliswe e-United States nase-Canada.Umaki we-ETL ubonisa ukuthi umkhiqizo uphumelele ukuhlolwa kokugunyazwa kwe-NRTL e-United States kanye ne-SCC e-Canada.I-Intertek ingenye yezinhlangano ezimbalwa zokunikeza izitifiketi eziqashelwa i-OSHA ne-SCC. I-Shenzhen anbo inobudlelwano obuseduze ne-Intertek, engasiza imikhiqizo yakho ithole isitifiketi se-ETL futhi ikunikeze ngamasevisi aphelele.Ukuqashelwa kophawu lwe-ETL kulingana nomaka we-UL noma i-CSA futhi kuhlangabezana nezindinganiso zokuphepha ezifanele.Ukuba nefulegi lekholomu ye-ETL yomkhiqizo kusho ukuthi uhlangabezane nezimfuneko eziphansi zezindinganiso zokuphepha komkhiqizo.Ngaphezu kwalokho, uphawu lwe-ETL luphinde lubonise ukuthi indawo yokukhiqiza yomkhiqizi ihlangabezana nezimfuneko ezithile ezijwayelekile, futhi icwaninga ngokulandela ukucwaninga kwefekthri kokulandelela ukuze kuqinisekiswe ukufana.I-ETL isineminyaka engaphezu kuka-100 ikhona. iminyaka.Izinhlamvu ezintathu ze-ETL zimfushane ze-Electrical Testing Labs eyasungulwa umsunguli uMnu. Edison ngo-1896.I-ETL imele ukuqamba okusha, okunomthelela, ukuzimela.nt nokuhlola umkhiqizo ovulekile kanye nolwazi olucebile. Isitifiketi se-ETLus (thina kuphela, akukho c) : Isitifiketi se-cETL (kuphela c, akukho nathi) : Isitifiketi se-cETlus (kuphela c, no us) : Isitifiketi se-cETlus (kuphela c, no us) : cETlus isitifiketi (kuphela c, no us) : Isitifiketi se-cETlus (kuphela c, no us)Uma unazo zombili, uthola izikhathi ezi-4 ngonyaka.
