Gas detector yog ib qho cuab yeej uas ntsuas tus nqi ntawm cov roj uas muaj nyob hauv cov huab cua ib puag ncig. Txhawm rau kom ntseeg tau tias cov lag luam tsim khoom muaj kev nyab xeeb, nws tau dav siv hauv kev lag luam tshuaj lom neeg, metallurgy, cov yeeb nkab hauv av, hluav taws xob hluav taws xob, tshuaj, thiab lwm yam kev lag luam. Yog li ntawd, peb yuav tsum xaiv cov khoom muaj npe nrov uas ua raws li lub teb chaws cov txheej txheem thaum peb yuav cov cuab yeej ntsuas roj. Yuav ua li cas peb thiaj txiav txim siab seb cov khoom puas tsim nyog lossis tsis, thiab peb yuav ua li cas thiaj li txiav txim siab ntawm kev yuav cov khoom lag luam?
Feem ntau hais lus, cov cuab yeej siv hluav taws xob tsim nyog yuav tsum tau lees paub los ntawm lub xeev. Tom ntej no, kuv yuav qhia koj seb yuav tsum muaj ntawv pov thawj dab tsi rau cov khoom siv roj.
1.3C ntawv pov thawj
Lub npe tag nrho ntawm 3C ntawv pov thawj yog "cov khoom pov thawj yuav tsum tau ua", lub npe Askiv yog Tuam Tshoj Compulsory Certification, thiab cov lus Askiv luv yog CCC. Nws yog kev soj ntsuam cov khoom lag luam raws li tsoomfwv Suav ua raws li cov cai thiab cov kev cai txhawm rau tiv thaiv tus kheej kev nyab xeeb thiab kev nyab xeeb hauv tebchaws ntawm cov neeg siv khoom thiab ntxiv dag zog rau kev tswj xyuas cov khoom zoo.
Lub logo 3C feem ntau yog muab tso rau ntawm qhov chaw ntawm cov khoom, los yog nias rau ntawm cov khoom los ntawm molding. Yog tias koj saib ze, koj yuav pom ntau lub oval "CCC" cov cim. Muaj ib qho random code tom qab txhua 3C logo, thiab txhua tus lej random muaj cov chaw tsim khoom thiab cov khoom lag luam sib raug. Thaum muab daim ntawv pov thawj cov khoom yuav tsum tau, lub chaw muab ntawv pov thawj kev tswj xyuas tau nkag mus rau cov khoom sib xws rau hauv lub computer database, thiab cov neeg siv khoom tuaj yeem nug cov cai los ntawm National Quality Certification Center.
Nws yuav tsum raug sau tseg tias 3C cim tsis yog lub cim zoo, tab sis tsuas yog daim ntawv pov thawj kev nyab xeeb yooj yim xwb. Uas yog hais tias, qhov no yog qhov yuav tsum tau daim ntawv pov thawj ntawm lub xeev, tsis muaj daim ntawv pov thawj no, nws tsis raug tso cai muag ntawm lub khw.
2. Cov ntaub ntawv pov thawj tawg
Cov ntaub ntawv pov thawj tawg yog ib qho kev sim niaj hnub siv los txiav txim siab seb lub tshuab ntsuas roj puas ua tau raws li qhov yuav tsum tau ua ntawm cov qauv pov thawj tawg, hom kev sim thiab hloov kho. Yog tias nws ua tau raws li qhov yuav tsum tau ua, daim ntawv pov thawj tawg-pov thawj sib thooj yuav raug muab. Thaum ua ntawv thov rau daim ntawv pov thawj tawg, lub tshuab ntes roj yuav tsum muab ntau cov ntaub ntawv tseem ceeb xws li daim ntawv pov thawj kev tsim nyog rau kev lag luam, daim ntawv pov thawj kev pov hwm kev lag luam, cov ntaub ntawv qhia, thiab cov qauv rau kev tshuaj xyuas cov ntawv pov thawj tawg. Yog li ntawd, peb yuav tsum tau xyuam xim xyuas seb puas muaj pov thawj tawg thaum xaiv lub ntsuas roj. Certificate of Qualification.
3. Daim ntawv tso cai rau kev tsim cov cuab yeej ntsuas thiab daim ntawv pov thawj tsim nyog rau kev teeb tsa thiab kho cov khoom siv hluav taws xob tawg.
Ob daim ntawv pov thawj no tsis yog rau lub tshuab ntes roj nws tus kheej, tab sis rau cov ntawv pov thawj ntawm cov chaw tsim khoom ntawm cov khoom siv roj. Thaum yuav khoom, peb yuav tsum nug cov chaw tsim khoom seb lawv puas muaj ob daim ntawv pov thawj no. Ob daim ntawv pov thawj no txiav txim siab seb lub khw muag khoom puas tuaj yeem tsim lossis kho thiab txhim kho cov cuab yeej ntsuas roj ntsig txog.
4. Daim ntawv tshuaj ntsuam xyuas
Thaum kawg, muaj daim ntawv tshuaj ntsuam xyuas txog lub tshuab ntsuas roj. Daim ntawv tshaj tawm tshuaj xyuas yuav tsum zoo dua yog daim ntawv tshuaj ntsuam xyuas los ntawm lub teb chaws tso cai ntsuas ntsuas lub tuam tsev. Nws muaj ntau yam tsis sib xws, kev ua haujlwm thiab cov ntaub ntawv ntxaws ntxaws ntawm lub ntsuas roj, uas tuaj yeem pab peb kom kawm sai txog cov cuab yeej no.
Thaum muas lub ntsuas roj, peb yuav tsum tsom mus xyuas seb cov khoom puas muaj cov ntawv pov thawj plaub no, kom tsis txhob yuav cov khoom cuav thiab cov khoom tsis zoo, uas yuav ua rau muaj teeb meem tsis tsim nyog rau kev tsim khoom lag luam.
