Chitsimikizo cha American Standard Charging Pile (II) – Zofunikira pa Kupeza Msika (OSHA/NRTL/ANSI)

Kusiyana koonekeratu pakati pa satifiketi ku United States ndi satifiketi m'madera ena ndi kusowa kwa chizindikiro chogwirizana komanso chodziwika bwino chotsata malamulo.

Ku China, zinthu zovomerezeka ziyenera kukhala ndi chizindikiro chovomerezeka cha 3C (China Compulsory Certification). Mabanki amagetsi opanda chizindikirochi saloledwa kunyamulidwa m'ndege; Zinthu zomwe zimatumizidwa ku Europe ziyenera kukhala ndi chizindikiro cha CE, chomwe chili ndi zofunikira kwambiri pa zilembo, kukula, ndi malo, apo ayi sizingadutse kuyang'aniridwa kwa kasitomu; Japan ilinso ndi chizindikiro chofanana cha PSE (Product Safety of Electrical Appliances&Materials), pomwe South Korea ili ndi chizindikiro cha KC.

Kawirikawiri, kulemba zilembo zotsatizana kumatsimikiziridwa ndi boma kudzera mu kupanga zisankho mogwirizana komanso kugwiritsa ntchito mphamvu zoyang'anira kuti zilimbikitse.

Mwachionekere, United States ilibe malamulo otere.

Kodi NRTL National Laboratory ku United States ndi chiyani?

Choyamba, NRTL (Nationally Recognised Testing Laboratory) ndi labotale yodziwika bwino ku United States. Ngakhale ili ndi dzina la National, si bungwe la dziko koma bungwe lachinsinsi. Bungwe lililonse ndi bungwe loyesa lingapemphe kuti likhale membala wa NRTL. Zofunikira zokha za 29 CFR 1910.7 ziyenera kukwaniritsidwa, ndi zofunikira zinazake kuphatikizapo:

• ✔ Kutha kuyesa ndikuwunika ngati zida zikukwaniritsa miyezo yoyenera yoyesera;
• ✔ Kukhazikitsa ulamuliro wokwanira pa kuzindikira zinthu zovomerezeka ndikuchita kafukufuku wotsatira pa kupanga kwenikweni;
• ✔ Wodziyimira pawokha kwa wogwiritsa ntchito (monga olemba ntchito omwe akukakamizidwa ndi zofunikira pa zida zoyesera) komanso wopanga kapena wogulitsa aliyense wa zinthu zovomerezeka;
• ✔ Pangani zotsatira zofufuza bwino komanso njira zothanirana ndi madandaulo ndi mikangano;

Pakadali pano, malinga ndi mndandanda wa labotale womwe wafalitsidwa patsamba lovomerezeka la OSHA, ma labotale 22 onse apeza ziyeneretso za NRTL. Kwenikweni, mabungwe odziwika bwino oyesa ndi kupereka satifiketi ali pamndandanda wa NRTL, monga UL ndi CSA, omwe ndi mabungwe oyesera akuluakulu ku North America.

Zindikirani:Tiyenera kudziwa kuti ma laboratories omwe ali ndi ziyeneretso za NRTL sangakhale ndi chitsimikizo cha chinthu china. Tiyeneranso kuwona ngati labotale ili ndi kuthekera kopanga miyezo ya chinthuchi.

(2) OSHA ndi NRTL

Miyezo yomwe yatchulidwa ndi labotale ya NRTL, yomwe imakhudza malo ochajira, ndi UL 2202 ndi UL 2594. Ndafufuza aliyense ndipo ndapeza kuti ma labotale akuluakulu pamsika amatha kupanga miyezo iwiriyi.

Pa kutumiza kunja malo ochapira, ndikofunikira kupeza labotale yokhala ndi ziyeneretso za NRTL, OSHA kuti ione kuchuluka kwa luso, kupititsa mayeso awo ndi kuvomerezedwa, ndikuyika chizindikiro chawo kuti chigulitsidwe m'deralo ku United States.

Chitsimikizo chochitidwa ndi mabungwe a UL chimagwiritsa ntchito logo ya UL, chitsimikizo chochitidwa ndi mabungwe a T Ü VS Ü D chimagwiritsa ntchito logo yapadera ya octagonal, ndipo chitsimikizo chochitidwa ndi T Ü V Rheinland chimagwiritsa ntchito logo ya Rheinland North America. Kuchokera pamalingaliro olamulira, palibe kusiyana kwakukulu pakulemba kwawo, chifukwa onse amadziwika ndi OSHA.

Chifukwa chake, opanga ma charger mulu ali ndi ufulu wosankha bungwe lopereka satifiketi lomwe limawayenerera, ndipo palibe chifukwa chosankha UL. Anthu ambiri amakhulupirira molakwika kuti UL ndiye chiyeneretso chovomerezeka ku United States, koma kwenikweni, UL ndi bungwe loyesa ndi kupereka satifiketi lachinsinsi ndipo lilibe ufulu wovomerezeka wovomerezeka.

（3） NFPA 70

Zinthu zamagetsi ku United States sizimangofunika kukwaniritsa satifiketi ya ma laboratories ovomerezeka a NRTL, komanso ziyenera kutsatira zomwe zafotokozedwa - NFPA 70.

NFPA 70 (National Fire Protection Association), yomwe imadziwikanso kuti NEC (National Electrical Code), dzina lachi China ndi lomwe timalidziwa bwino - American Electrical Code. Ku United States, pafupifupi mainjiniya onse amagetsi ali ndi laputopu.

Kodi sizodabwitsa kuti code yamagetsi ku United States ili ndi dzina lomwelo la National Fire Protection Commission?

NFPA (National Fire Protection Association), Ngakhale kuti imatchedwa National Fire Protection Association, ndi bungwe lomwe si la boma. Monga momwe zilili ndi NBA basketball ligi ndi NFL football ligi ku United States, ndi mabungwe aboma amalonda. Bungwe la NFPA linakhazikitsidwa mu 1896 ndi cholinga chogwirizanitsa mapaipi amadzi ndi mainchesi amadzi a zida zodzitetezera ku moto zakomweko - makina odzithira okha.

Chidule cha (4)

Tiyeni tifotokoze mwachidule zomwe takambirana. Ngati zinthu zogulira zinthu zotumizidwa ku United States:

• ● Chogulitsacho chokha, ma DC piles ayenera kutsatira zofunikira za UL 2202, ndipo ma AC piles ayenera kutsatira zofunikira za UL 2594;
• ● Kukhazikitsa ndi kulumikiza mawaya kuyenera kutsatira zofunikira za NFPA 70 625 ku United States;
• ● Kuyesa ndi kupereka satifiketi kuyenera kutsatira ma laboratories ovomerezeka a NRTL, monga UL/CSA/T Ü VS Ü D, ndi zina zotero;

Chithunzi chatsatanetsatane ndi ichi:

Pomaliza, ziyenera kutsindika kuti satifiketi ya UL si njira yokhayo yolowera mumsika wa ku US. Kuyesa ndi satifiketi kuchokera ku mabungwe ena kumatsatiranso malamulo ndi malangizo aku US.

Zachidziwikire, UL ndi bungwe lakale kwambiri lopereka satifiketi ya mtundu ku United States, lomwe likuvomerezedwa kwambiri mdziko lonse. Kupeza satifiketi ya UL kudzawonjezera mbiri ya msika. Mtengo wake ndi monga tafotokozera kale, mtengo wake komanso nthawi yake sizosangalatsa kwenikweni.

Chifukwa chake, kusankha kwa bungwe lovomerezeka la mabizinesi am'nyumba kuyenera kukhala koyenera komanso koyenera pakati pa bajeti yawo, malo omwe zinthu zili, ndi zofunikira za ogula aku America.
