Keeb Kwm thiab Hnub Ua Haujlwm
1. GB31241-2014 tau luam tawm rau lub Kaum Ob Hlis 5th, 2014;
2. GB31241-2014 tau raug coj los siv rau lub Yim Hli 1st, 2015.;
3. Thaum Lub Kaum Hli 15th, 2015, Certification and Accreditation Administration tau tshaj tawm ib qho kev daws teeb meem ntawm cov qauv xeem ntxiv GB31241 rau cov khoom tseem ceeb "roj teeb" ntawm cov khoom siv suab thiab video, cov khoom siv thev naus laus zis thiab cov khoom siv hauv xov tooj. Qhov kev daws teeb meem tau teev tseg tias cov roj teeb lithium siv rau hauv cov khoom saum toj no yuav tsum tau sim sim raws li GB31241-2014, lossis tau txais daim ntawv pov thawj cais.
Nco tseg: GB 31241-2014 yog tus qauv tsim nyog hauv tebchaws. Tag nrho cov khoom siv roj teeb lithium muag hauv Suav teb yuav tsum ua raws li tus qauv GB31241. Cov qauv no yuav raug siv rau hauv cov qauv qauv tshiab rau kev kuaj xyuas lub tebchaws, lub xeev thiab hauv zos.
▍ Scope of Certification
GB31241-2014Lithium ion hlwb thiab cov roj teeb siv hauv cov khoom siv hluav taws xob portable - Cov kev xav tau ntawm kev nyab xeeb
Cov ntaub ntawv pov thawjFeem ntau yog rau cov khoom siv hluav taws xob hauv xov tooj ntawm tes uas tau teem sijhawm tsawg dua 18kg thiab tuaj yeem nqa tau los ntawm cov neeg siv feem ntau. Cov piv txwv tseem ceeb yog raws li hauv qab no. Cov khoom siv hluav taws xob portable uas tau teev tseg hauv qab no tsis suav nrog txhua yam khoom, yog li cov khoom lag luam tsis tau teev tseg tsis tas yuav nyob sab nraud ntawm tus qauv no.
Cov cuab yeej siv tau: Cov roj teeb lithium-ion thiab cov roj teeb uas siv rau hauv cov khoom siv yuav tsum tau ua raws li cov qauv kev cai.
| Electronic khoom qeb | Cov qauv nthuav dav ntawm ntau hom khoom siv hluav taws xob |
| Portable cov khoom siv hauv chaw ua haujlwm | phau ntawv, pda, thiab lwm yam. |
| Cov khoom siv sib txuas lus txawb | xov tooj ntawm tes, xov tooj cordless, Bluetooth headset, walkie-talkie, thiab lwm yam. |

▍ Vim li cas MCM?
● Kev lees paub Kev Tsim Nyog: MCM yog CQC qhov chaw kuaj pom muaj ntawv pov thawj thiab CESI kuaj pom zoo. Daim ntawv tshaj tawm xeem tuaj yeem thov ncaj qha rau CQC lossis CESI daim ntawv pov thawj;
● Kev pab txhawb nqa: MCM muaj ntau yam khoom siv kuaj GB31241 thiab tau nruab nrog ntau tshaj 10 tus kws tshaj lij los ua qhov kev tshawb fawb tob txog kev sim tshuab, ntawv pov thawj, kev kuaj xyuas lub Hoobkas thiab lwm cov txheej txheem, uas tuaj yeem muab tau ntau dua thiab kho tau raws li GB 31241 daim ntawv pov thawj cov kev pabcuam thoob ntiaj teb. cov neeg siv khoom.
Nrog ntau qhov xwm txheej tshwm sim los ntawm lithium-ion roj teeb tshwm sim, Cov neeg muaj kev txhawj xeeb ntau dua txog cov roj teeb thermal khiav tawm, vim tias thermal khiav tawm hauv ib lub xov tooj yuav kis tau cua sov mus rau lwm lub hlwb, ua rau kaw tag nrho cov roj teeb.
Kev lig kev cai peb yuav ua kom thermal khiav tawm los ntawm cua sov, pinning lossis overcharging thaum kuaj. Txawm li cas los xij, cov txheej txheem no tsis tuaj yeem tswj xyuas cov thermal khiav hauv lub xov tooj ntawm tes, thiab lawv tuaj yeem siv tau yooj yim thaum kuaj cov roj teeb. Tsis ntev los no tib neeg tab tom tsim txoj hauv kev tshiab los ua kom thermal khiav tawm. Qhov kev sim Propagation nyob rau hauv tshiab IEC 62619: 2022 yog ib qho piv txwv, thiab nws tau kwv yees tias txoj kev no yuav siv dav rau yav tom ntej. Kab lus no yog los qhia qee txoj hauv kev tshiab uas tab tom tshawb fawb.
Laser hluav taws xob yog kom sov ib cheeb tsam me me nrog lub zog siab laser mem tes. Cov cua sov yuav ua rau hauv cov khoom siv. Laser hluav taws xob yog dav siv nyob rau hauv cov cheeb tsam ntawm cov khoom siv, xws li vuam, txuas thiab txiav. Feem ntau muaj ntau hom laser raws li hauv qab no:
Muaj CT scan ntawm lub xov tooj ntawm tes uas tsis tau tshwm sim, nws tuaj yeem pom tias tsis muaj cov qauv tsim tshwj tsis yog lub qhov ntawm qhov chaw. Nws txhais tau tias laser yog kev taw qhia, thiab lub zog siab, thiab qhov chaw cua sov yog qhov tseeb. Yog li ntawd, laser yog ib txoj hauv kev zoo rau kev kuaj. Peb tuaj yeem tswj tau qhov sib txawv, thiab suav cov tswv yim thiab cov khoom siv hluav taws xob kom raug. Meanwhile laser muaj qhov zoo ntawm cua sov thiab pinning, zoo li cua sov ceev, thiab ntau tswj tau. Laser muaj ntau yam zoo xws li:
