ATPV yog arc flash tiv thaiv tus nqi ntsuas hauvcal / cm². Nws qhia txog qhov xwm txheej thermal zog ntawm qhov arc - ntsuas cov ntaub ntawv muab 50% qhov tshwm sim ntawm kev ncav cuag qhov pib thib ob -degree hlawv, hauv qab ASTM F1959/F1959M arc kuaj.
Rau PPE kev yuav khoom, qhov ntsuas qhov ntsuas ntawm cov tsoos tsho yuav tsum yogsib npaug los yog siab tshaj qhov suav qhov xwm txheej zoglos ntawm qhov chaw kawm arc flash. Ib khaub ncaws ntsuas8 cal/cm²tsis yog qhov hloov pauv rau a25 cal / cm²daim ntawv lo ua haujlwm, txawm tias ob qho tib si yog nplaim taws- tiv taus. OSHA cov lus qhia tseem hais tias cov tswv ntiav haujlwm yuav tsum xaiv PPE raws li suav qhov xwm txheej zog rau cov teeb meem arc flash.
ATPV Lub ntsiab lus hauv cal/cm²: Tus naj npawb tiag tiag tswj
ATPV sawv rauArc Thermal Performance Tus nqi. Nws tsis yog qhov hnyav ntawm cov ntaub, tsis yog cov nplaim hluav taws sib kis, thiab tsis yog qhov kev thov dav dav "fireproof". Nws yog ntsuas qhov ntsuas kub tiv thaiv tus nqi raws li kev ntsuas hluav taws xob arc raug.
Hauv cov ntsiab lus ntawm kev yuav khoom, ATPV teb ib lo lus nug ncaj qha:
Lub zog arc flash ntau npaum li cas tuaj yeem ua rau cov ntaub lossis cov ris tsho no nqus tau ua ntej tus neeg hnav ntsib 50% qhov tshwm sim thib ob -degree hlawv pib?
ASTM F1959 / F1959M yog siv los txiav txim qhov ntsuas arc ntawm cov ntaub ntawv khaub ncaws lossis cov txheej txheem txheej txheej. Yog tias cov khoom tawg tau qhib ua ntej mus txog qhov chaw kub hnyiab, tus nqi tshaj tawm yuav yogEBTtsis yog ATPV; ob qho tib si yog qhov kev ntsuas arc, tab sis hom tsis ua haujlwm txawv.
ATPV vs. EBT Raws li ASTM F1959/F1959M
| Lub sij hawm | Chav tsev | Qhov Nws Qhia | Lub ntsiab lus ntawm kev yuav khoom |
|---|---|---|---|
| ATPV | cal / cm² | Thermal zog theem txuas mus rau hlawv qhov pib pib | Npuag thaiv arc cua sov mus txog qhov ntsuas ntsuas |
| EBT | cal / cm² | Lub zog breakopen pib | Npuag qhib ua ntej qhov chaw kub hnyiab mus txog |
| Arc Rating | cal / cm² | Qhov qhia qis dua ntawm ATPV thiab EBT | Siv tus nqi no rau kev xaiv PPE |
| Teeb meem Zog | cal / cm² | Xam qhov chaw txaus ntshai ntawm kev ua haujlwm nrug | PPE arc ntsuam xyuas yuav tsum tau raws li los yog tshaj tus nqi no |
Ib qho kev yuav khoom yuam kev yog khoFR khaub ncawsthiabarc- ntsuas khaub ncawsraws li interchangeable. FR npuag tus kheej- tua tom qab hluav taws kub; arc-rated ntaub tau raug sim rau thermal zog tiv thaiv nyob rau hauv hluav taws xob arc raug. Arc flash PPE specifications yuav tsum thov lub arc ntsuam xyuas nyob rau hauvcal / cm², tsis tsuas yog "FR paj rwb" lossis "flame-tiv taus tiav."
Txoj Cai HRC 1–4 thiab tam sim no PPE Qeb Mapping
Ntau tus neeg yuav khoom tseem siv "HRC" hauv RFQs, tab sis tam sim no NFPA 70E hom lus feem ntau sau uaArc Flash PPE Qeb. Qeb-raws li kev yuav khoom tseem muaj txiaj ntsig thaum lub vev xaib siv PPE qeb cov lus es tsis yog qhov xwm txheej ntsuas hluav taws xob. Kev lag luam cov ntsiab lus ntawm NFPA 70E piav qhia plaub pawg PPE nrog qhov tsawg kawg nkaus arc ntsuam xyuas ntawm4, 8, 25, thiab 40 cal / cm².
Arc Flash PPE Qeb 1–4: Yam tsawg kawg nkaus Arc Rating thiab Hom tsoos tsho
| Lub sij hawm qub | Tam sim no Buyer Language | Yam tsawg kawg nkaus Arc Rating | Common Garment System | Hom Khoom Taw Qhia |

Rau arc flash PPE kev sib tw, xa qhov xwm txheej lub zog tus nqi, lub hom phiaj arc ntsuam xyuas, hom tsoos tsho, yuav tsum tau ntxuav, thiab cov ntsiab lus cuam tshuam.
Thov OEM FR Clothing Quotekom tau txais lub Hoobkas- cov khoom siv sab nraud thiab kev tshuaj xyuas kev tsim kho ua ntej bulk sampling.
ATPV Procurement Risk: Cov Khaub Ncaws yog ib qho system, tsis yog ntaub xwb
Arc flash PPE ua tsis tiav thaum ib qho khoom siv nyob rau hauv - qhia. Cov neeg yuav khoom feem ntau tsom rau lub plhaub npuag thiab tsis quav ntsej luas, xov, daim ntawv lo, kaw, hnab tshos, thiab daim kab xev. Hauv ib qho arc- cov ris tsho ntsuas, qhov tsis muaj zog tshaj plaws tuaj yeem txiav txim siab qhov ua tau zoo.
FR Cov Khaub Ncaws Cov Khaub Ncaws Uas Yuav Tsum Ua Raws Li Cov Khoom Siv Hluav Taws Xob
| Cheebtsam | Yam tsawg kawg ntawm Kev Tshawb Fawb | Risk yog Ignored |

Cov Lus Ceeb Toom Kawg rau ATPV-Rated FR Clothing
ATPV yog tus lej tswj kev yuav khoom. Nws txuas hluav taws xob kev ntsuas kev pheej hmoo, FR fabric engineering, tsoos tsho tsim, xaiv luas, ntxuav durability, thiab cov ntaub ntawv muab khoom siv rau hauv ib qho kev txiav txim siab.
Rau PPE distributors thiab cov neeg yuav khoom lag luam, cov khoom lag luam raug yog:
Tau txais kev kawm arc flash lossis PPE qeb yuav tsum tau ua.
Txhais qhov tsawg kawg nkaus arc ntsuas hauvcal / cm².
Xaiv cov ntaub thiab tsoos tsho system.
Txheeb xyuas FR trims, daim kab xev xaim, xov, zipper, thiab daim ntawv lo.
Pom zoo ua ntej - qauv tsim khoom.
Tshawb xyuas cov khoom xa tuaj ntau tiv thaiv cov ntaub ntau, qhov ntev, luas, daim ntawv lo, thiab cov ntaub ntawv ntim khoom.
Rau OEM FR khaub ncaws yuav khoom, xa koj lub hom phiaj ATPV ntsuam xyuas, ntaub GSM, hom khaub ncaws, xav tau daim kab xev, ntxuav tus qauv, qhov ntau thiab tsawg, thiab xaj kom muaj nuj nqis.

FAQ
Q: Dab tsi ATPV Rating Yuav tsum Cov Neeg Yuav Khoom Qhia Rau Arc Flash PPE?
A: Qhia qhov ntsuas arc sib npaug lossis siab dua qhov ntsuas qhov xwm txheej ntawm lub vev xaib arc flash daim ntawv lo. Yog tias daim ntawv qhia pom tias 8.6 cal / cm², siv PPE ntsuas saum toj no 8.6 cal / cm², tsis yog 8.6 cal / cm² garment.
Q: Lub Hoobkas Tuam Tshoj puas tuaj yeem tsim ATPV-Rated FR khaub ncaws rau OEM xaj?
A: Yog, yog tias RFQ suav nrog lub hom phiaj ATPV, cov ntaub ntawv muaj pes tsawg leeg, tsoos tsho style, FR trims, yuav tsum tau ntxuav, thiab cov ntaub ntawv xeem yuav tsum tau ua. Cov neeg yuav khoom yuav tsum thov ASTM F1959 / F1959M arc rating cov ntaub ntawv thiab paub meej tias daim ntawv tshaj tawm npog cov ntaub nkaus xwb lossis tag nrho cov tsoos tsho.
Q: Puas yog Reflective Tape tso cai rau Arc Flash FR khaub ncaws?
A: Yog, tab sis nws yuav tsum yog FR- tau txais daim kab xev xaim pom zoo rau cov ntaub ntawv siv tsoos tsho. Daim kab xev ntsuas tus qauv yuav yaj, tshem tawm, lossis ua tsis tiav thaum raug tshav kub. Qhia meej FR reflective daim kab xev, FR xov, thiab tsoos tsho-qib ntsuas thaum xav tau kev pom kev pom.
