▍ WERCSmart REGISTRATION yog dab tsi?

WERCSmart yog lub npe luv ntawm World Environmental Regulatory Compliance Standard.

WERCSmart yog lub tuam txhab sau npe cov khoom lag luam tsim los ntawm US tuam txhab hu ua The Wercs. Nws yog lub hom phiaj los muab kev saib xyuas kev nyab xeeb ntawm cov khoom lag luam rau cov khw muag khoom loj hauv Asmeskas thiab Canada, thiab ua kom cov khoom yuav khoom yooj yim dua. Hauv cov txheej txheem ntawm kev muag, thauj, khaws cia thiab pov tseg cov khoom ntawm cov khw muag khoom thiab cov neeg tau txais kev tso npe, cov khoom lag luam yuav ntsib cov teeb meem nyuaj ntxiv los ntawm tsoomfwv, xeev lossis cov cai hauv zos. Feem ntau, Daim Ntawv Qhia Txog Kev Nyab Xeeb (SDSs) muab nrog rau cov khoom lag luam tsis suav nrog cov ntaub ntawv tsim nyog uas cov ntaub ntawv qhia tau hais tias ua raws li cov cai thiab cov cai. Thaum WERCSmart hloov cov ntaub ntawv cov khoom mus rau qhov ua raws li cov cai thiab cov cai.

▍ Scope ntawm cov khoom sau npe

Cov khw muag khoom txiav txim siab txog kev sau npe rau txhua tus neeg muag khoom. Cov pawg hauv qab no yuav tsum tau sau npe rau kev siv. Txawm li cas los xij, cov npe hauv qab no tsis tiav, yog li kev txheeb xyuas ntawm kev sau npe yuav tsum tau nrog koj cov neeg yuav khoom tau pom zoo.

◆ Txhua yam khoom muaj tshuaj lom neeg

◆ OTC khoom thiab khoom noj khoom haus ntxiv

◆ Cov Khoom Siv Kho Tus Kheej

◆ Cov khoom siv roj teeb

◆ Cov khoom lag luam nrog Circuit Boards lossis Electronics

◆ Teeb Teeb

◆ Ua Cov Roj

◆ Cov zaub mov xa los ntawm Aerosol lossis Bag-On-Valve

▍ Vim li cas MCM?

● Kev txhawb nqa cov neeg ua haujlwm: MCM tau nruab nrog ib pab neeg tshaj lij uas kawm SDS cov cai thiab cov cai ntev. Lawv muaj kev paub tob txog kev hloov ntawm cov cai thiab cov cai thiab tau muab kev tso cai SDS kev pab rau ib xyoo caum.

● Cov kev pab cuam kaw-loop: MCM muaj cov neeg ua haujlwm tshaj lij sib txuas lus nrog cov neeg soj ntsuam los ntawm WERCSmart, ua kom cov txheej txheem kev sau npe thiab pov thawj zoo. Txog tam sim no, MCM tau muab kev pabcuam rau npe WERCSmart rau ntau dua 200 tus neeg siv khoom.

UL 1973: 2022 tau luam tawm thaum Lub Ob Hlis 25th. Cov qauv no yog ua raws li ob lub tswv yim tawm tswv yim tawm thaum lub Tsib Hlis thiab Lub Kaum Hli 2021. Cov qauv hloov kho nthuav dav, suav nrog lub zog pab tsheb (xws li teeb pom kev zoo thiab kev sib txuas lus).
Append 7.7 Transformer: transformer rau roj teeb system yuav tsum tau ntawv pov thawj raws li UL 1562 thiab UL 1310 lossis cov qauv tsim nyog. Tsawg voltage tuaj yeem lees paub hauv qab 26.6.
Hloov tshiab 7.9: Kev Tiv Thaiv Circuits thiab Kev Tswj: roj teeb lub cev yuav tsum muab hloov lossis tawg, qhov tsawg kawg nkaus yuav tsum yog 60V tsis yog 50V. Ntxiv kev xav tau rau kev qhia rau overcurrent fuse
Hloov kho 7.12 Cells (roj teeb thiab electrochemical capacitor): Rau rechargeable Li-ion hlwb, yuav tsum tau kuaj nyob rau hauv annex E, yam tsis xav txog UL 1642. Cells kuj yuav tsum tau soj ntsuam yog tias ua tau raws li qhov kev thov ntawm kev nyab xeeb tsim, xws li cov khoom thiab txoj hauj lwm ntawm insulator, kev them nyiaj ntawm anode thiab cathode, thiab lwm yam.
Append 18 Overload Under Discharge: Ntsuas lub peev xwm ntawm cov roj teeb uas muaj peev xwm tshaj tawm hauv qab tso tawm. Muaj ob txoj hauv kev rau kev sim: thawj zaug yog nyob rau hauv overload nyob rau hauv kev tso tawm nyob rau hauv uas tam sim no siab tshaj qhov ntsuas qhov siab tshaj tawm tam sim no tab sis qis dua tam sim no ntawm BMS overcurrent tiv thaiv; qhov thib ob yog siab tshaj BMS tshaj kev tiv thaiv tam sim no tab sis qis dua qib 1 tiv thaiv tam sim no.
