Kutulutsidwa kwa UL 2054 kope lachitatu
Kutulutsidwa kwaMtengo wa UL2054kope lachitatu,
Mtengo wa UL2054,
▍Kodi cTUVus & ETL CERTIFICATION ndi chiyani?
OSHA (Occupational Safety and Health Administration), yogwirizana ndi US DOL (Department of Labor), ikufuna kuti zinthu zonse zogwiritsidwa ntchito kuntchito ziyenera kuyesedwa ndi kutsimikiziridwa ndi NRTL zisanagulitsidwe pamsika. Miyezo yoyezetsa yogwiritsidwa ntchito ikuphatikiza miyezo ya American National Standards Institute (ANSI); Miyezo ya American Society for Testing Material (ASTM), Miyezo ya Underwriter Laboratory (UL), ndi miyezo ya bungwe lozindikiritsa fakitale.
▍OSHA, NRTL, cTUVus, ETL ndi UL matanthauzo ndi ubale
OSHA:Chidule cha Occupational Safety and Health Administration. Ndi mgwirizano wa US DOL (Department of Labor).
Mtengo wa NRTL:Chidule cha Nationally Recognized Testing Laboratory. Ndiwoyang'anira kuvomerezeka kwa labu. Mpaka pano, pali mabungwe oyesa 18 omwe avomerezedwa ndi NRTL, kuphatikiza TUV, ITS, MET ndi zina zotero.
cTUVus:Chizindikiro cha TUVRh ku North America.
Mtengo wa ETL:Chidule cha American Electrical Testing Laboratory. Idakhazikitsidwa mu 1896 ndi Albert Einstein, woyambitsa waku America.
UL:Malingaliro a magawo a Underwriter Laboratories Inc.

▍Chifukwa chiyani MCM?
● Thandizo Lofewa kuchokera ku qualification ndi teknoloji:Monga labu yoyesa mboni ya TUVRH ndi ITS ku North America Certification, MCM imatha kuyesa mitundu yonse ndikupereka ntchito zabwinoko posinthana ukadaulo maso ndi maso.
● Thandizo lolimba laukadaulo:MCM ili ndi zida zonse zoyezera mabatire akuluakulu, ang'onoang'ono komanso olondola (mwachitsanzo, galimoto yamagetsi yamagetsi, mphamvu zosungiramo zinthu, ndi zinthu zamagetsi zamagetsi), zomwe zimatha kupereka ntchito zonse zoyezera batire ndi ziphaso ku North America, zomwe zimakwaniritsa miyezo. UL2580, UL1973, UL2271, UL1642, UL2054 ndi zina zotero.
Mtengo wa UL2054Ed.3 idatulutsidwa pa Novembara 17, 2021. Monga membala wa mulingo wa UL, MCM idatenga nawo gawo pakuwunikanso mulingowo, ndipo idapereka malingaliro omveka pakusintha komwe kudakhazikitsidwa pambuyo pake.
Zosintha zomwe zidapangidwa pamiyezo zimakhudzidwa makamaka ndi zinthu zisanu, zomwe zimafotokozedwa momveka bwino motere:Kukonzanso kosiyanasiyana kumapangidwa mu Mulingo wonse; Ndime 2 – 5, 6.1.2 – 6.1.4,
6.5.1, 8.1, 8.2, 11.10, 12.13, 13.3, 14.7, 15.2, 16.6, mutu wa Gawo 23, 24.1, Zowonjezera A. Kufotokozera zofunikira za zolemba zomatira; Gawo 29, 30.1, 30.2.Kuwonjezera zofunika ndi njira za Mark Durability Test .Made Limited Power Source Test ndi chosankha; 7.1.Anafotokozera kukana kwakunja muyeso mu 11.11. Mayeso a Short Circuit adanenedwa kuti agwiritse ntchito waya wamkuwa kupita kufupipafupi kwa ma anode abwino ndi oipa pa gawo la 9.11 la chikhalidwe choyambirira, tsopano linasinthidwa ngati kugwiritsa ntchito 80 ± 20m.
Ω zotsutsa zakunja.
Kuwonjeza ndime 6.3: Zofunikira zonse pamapangidwe a mawaya ndi ma terminals: Waya uyenera kukhala wotchingidwa, ndipo uyenera kukwaniritsa zofunikira za UL 758 poganizira ngati kutentha komwe kungathe kuchitika mu paketi ya batri ndizovomerezeka. zikhazikitsidwe mwamakina, ndipo kulumikizidwa kwamagetsi kuyenera kuperekedwa, ndipo pasakhale zovuta zolumikizirana ndi ma terminals. Mtsogoleriyo uyenera kukhala wotetezeka, ndipo ukhale kutali ndi mbali zakuthwa ndi mbali zina zomwe zingawononge makina oteteza waya.
