Daim Ntawv Pov Thawj American Standard Charging Pile (II) - Cov Kev Cai Nkag Mus Rau Kev Ua Lag Luam (OSHA / NRTL / ANSI)

Qhov sib txawv pom tseeb tshaj plaws ntawm daim ntawv pov thawj hauv Tebchaws Meskas thiab daim ntawv pov thawj hauv lwm thaj chaw yog qhov tsis muaj daim ntawv lo ua raws cai sib koom ua ke thiab tshwj xeeb.

Nyob rau hauv Suav teb, cov khoom lag luam uas ua raws li txoj cai yuav tsum muaj daim ntawv lo nrog lub cim 3C (China Compulsory Certification). Cov txhab nyiaj fais fab uas tsis muaj lub cim no tsis raug tso cai nqa saum dav hlau; Cov khoom xa tawm mus rau Tebchaws Europe yuav tsum muaj lub cim CE, uas muaj cov kev cai nruj rau cov ntawv, qhov loj me, thiab qhov chaw, txwv tsis pub lawv yuav tsis dhau kev tshuaj xyuas kev lis kev cai; Nyiv Pooj kuj muaj lub logo PSE (Product Safety of Electrical Appliances & Materials) sib xws, thaum Kaus Lim Qab Teb muaj lub logo KC.

Feem ntau, kev sau npe ua raws li txoj cai yog txiav txim los ntawm tsoomfwv los ntawm kev txiav txim siab ua ke thiab kev siv lub hwj chim ntawm kev tswj hwm los txhawb nws.

Nws yog qhov tseeb tias Tebchaws Meskas tsis muaj cov cai zoo li no.

NRTL National Laboratory hauv Tebchaws Meskas yog dab tsi?

Ua ntej, NRTL (Lub Chaw Kuaj Mob Uas Tau Txais Kev Pom Zoo Hauv Tebchaws) yog lub chaw kuaj mob uas tau txais kev pom zoo hauv tebchaws Meskas. Txawm hais tias nws muaj lub npe hu ua Lub Tebchaws, nws tsis yog lub koom haum hauv tebchaws tab sis yog lub koom haum ntiag tug. Txhua lub koom haum thiab lub chaw kuaj mob tuaj yeem thov los ua ib tug tswv cuab ntawm NRTL. Tsuas yog cov kev cai ntawm 29 CFR 1910.7 xwb thiaj li yuav tsum tau ua tiav, nrog rau cov kev cai tshwj xeeb suav nrog:

• ✔ Muaj peev xwm sim thiab soj ntsuam seb cov khoom siv puas ua tau raws li cov qauv kev sim tsim nyog;
• ✔ Siv kev tswj xyuas txaus rau kev txheeb xyuas cov khoom lag luam tau ntawv pov thawj thiab ua kev tshuaj xyuas tom qab ntawm kev tsim khoom tiag tiag;
• ✔ Tsis muaj kev ywj pheej kiag li ntawm tus neeg siv (piv txwv li tus tswv ntiav haujlwm raug txwv los ntawm cov kev cai ntawm cov khoom siv kuaj) thiab txhua tus neeg tsim khoom lossis tus neeg muab khoom ntawm cov khoom tau ntawv pov thawj;
• ✔ Tsim cov txiaj ntsig tshawb nrhiav thiab cov txheej txheem zoo rau kev daws cov lus tsis txaus siab thiab kev tsis sib haum xeeb;

Tam sim no, raws li daim ntawv teev cov chaw kuaj mob uas tau tshaj tawm rau ntawm lub vev xaib OSHA, tag nrho muaj 22 lub chaw kuaj mob tau txais cov ntawv pov thawj NRTL. Yeej, cov chaw kuaj mob thiab cov ntawv pov thawj paub zoo nyob rau hauv daim ntawv teev npe NRTL, xws li UL thiab CSA, uas yog cov chaw kuaj mob tseem ceeb hauv North America.

Lus Cim:Yuav tsum nco ntsoov tias cov chaw kuaj mob uas tau txais daim ntawv pov thawj NRTL tej zaum yuav tsis muaj peev xwm lees paub qee yam khoom. Peb kuj yuav tsum xyuas seb lub chaw kuaj mob puas muaj peev xwm tsim cov qauv rau cov khoom no.

(2) OSHA thiab NRTL

Cov qauv uas NRTL chav kuaj teev tseg, uas cuam tshuam txog cov chaw them hluav taws xob, yog UL 2202 thiab UL 2594. Kuv tau kuaj xyuas txhua tus thiab pom tias cov chaw kuaj mob tseem ceeb hauv khw muaj peev xwm tsim tau ob tus qauv no.

Rau kev xa tawm cov chaw them hluav taws xob, nws tsuas yog tsim nyog nrhiav lub chaw kuaj mob uas muaj daim ntawv pov thawj NRTL, OSHA los xyuas qhov ntau thiab tsawg ntawm cov peev xwm, dhau lawv qhov kev xeem thiab kev lees paub, thiab muab lawv lub logo rau nws kom muag hauv zos hauv Tebchaws Meskas.

Daim ntawv pov thawj uas ua los ntawm cov tsev kawm ntawv UL siv lub logo UL, daim ntawv pov thawj uas ua los ntawm T Ü VS Ü D cov tsev kawm ntawv siv lub logo octagonal tshwj xeeb, thiab daim ntawv pov thawj uas ua los ntawm T Ü V Rheinland siv lub logo North American ntawm Rheinland. Los ntawm kev pom ntawm txoj cai, tsis muaj qhov sib txawv tseem ceeb hauv lawv daim ntawv lo, vim tias lawv txhua tus tau lees paub los ntawm OSHA.

Yog li ntawd, cov chaw tsim khoom them nqi hluav taws xob muaj kev ywj pheej xaiv lub koom haum pov thawj uas haum rau lawv, thiab tsis tas yuav xaiv UL. Muaj ntau tus neeg ntseeg yuam kev tias UL yog daim ntawv pov thawj nkag mus rau Tebchaws Meskas, tab sis qhov tseeb, UL tsuas yog lub koom haum kuaj thiab ntawv pov thawj ntiag tug thiab tsis muaj cai tswjfwm kev tswj hwm.

(3) NFPA 70

Cov khoom siv hluav taws xob hauv Tebchaws Meskas tsis yog tsuas yog yuav tsum ua raws li daim ntawv pov thawj ntawm NRTL cov chaw soj nstuam uas tau lees paub xwb, tab sis kuj yuav tsum ua raws li cov lus qhia tshwj xeeb - NFPA 70.

NFPA 70 (Lub Koom Haum Tiv Thaiv Hluav Taws Hauv Tebchaws), Kuj tseem hu ua NEC (National Electrical Code), lub npe Suav yog qhov peb paub zoo - American Electrical Code. Hauv Tebchaws Meskas, yuav luag txhua tus kws ua hluav taws xob muaj lub laptop.

Puas yog nws txawv heev uas cov cai hluav taws xob hauv Tebchaws Meskas muaj tib lub npe li National Fire Protection Commission?

NFPA (Lub Koom Haum Tiv Thaiv Hluav Taws Hauv Tebchaws), Txawm hais tias hu ua Lub Koom Haum Tiv Thaiv Hluav Taws Hauv Tebchaws, nws kuj yog ib lub koom haum tsis yog tsoomfwv. Ib yam li pab koomtes basketball NBA thiab pab koomtes football NFL hauv Tebchaws Meskas, lawv yog cov koom haum pej xeem ua lag luam. Lub koom haum NFPA tau tsim muaj xyoo 1896 nrog lub hom phiaj ntawm kev sib koom ua ke ntawm txoj kab uas hla thiab cov kav dej ntawm cov khoom siv tiv thaiv hluav taws hauv zos - cov tshuab txau dej tsis siv neeg.

(4) Cov Lus Qhia Luv Luv

Cia peb sau cov ntsiab lus uas peb nyuam qhuav tham txog. Yog tias cov khoom siv chaw nres tsheb them hluav taws xob raug xa tawm mus rau Tebchaws Meskas:

• ● Cov khoom nws tus kheej, DC piles yuav tsum ua raws li UL 2202 cov kev cai, thiab AC piles yuav tsum ua raws li UL 2594 cov kev cai;
• ● Kev teeb tsa thiab kev txuas hluav taws xob yuav tsum ua raws li cov cai ntawm NFPA 70 625 hauv Tebchaws Meskas;
• ● Kev kuaj thiab daim ntawv pov thawj yuav tsum ua raws li NRTL cov chaw soj nstuam uas tau lees paub, xws li UL/CSA/T Ü VS Ü D, thiab lwm yam;

Daim duab qhia ntxaws ntxaws yog raws li nram no:

Thaum kawg, yuav tsum tau hais tias daim ntawv pov thawj UL tsis yog tib txoj kev nkag mus rau hauv kev lag luam hauv Tebchaws Meskas. Kev kuaj thiab daim ntawv pov thawj los ntawm lwm lub koom haum kuj ua raws li cov cai thiab kev cai lij choj ntawm Tebchaws Meskas.

Tau kawg, UL yog ib lub koom haum pov thawj hom lag luam qub heev hauv Tebchaws Meskas, nrog kev lees paub thoob tebchaws siab. Kev tau txais daim ntawv pov thawj UL yuav ua rau lub koob npe nrov ntawm kev ua lag luam nce ntxiv. Tus nqi yog raws li tau hais ua ntej, ob qho tib si tus nqi thiab lub voj voog tsis zoo heev.

Yog li ntawd, qhov kev xaiv tshwj xeeb ntawm lub tsev kawm ntawv pov thawj rau cov tuam txhab ua pile hauv tsev yuav tsum muaj kev sib npaug thiab sib npaug ntawm lawv cov peev nyiaj, kev tso khoom, thiab cov kev xav tau ntawm cov neeg yuav khoom Asmeskas.
