TS EN ISO 14644-1 Cov chav huv huv piav qhia txog huab cua huv npaum li cas los ntawm kev ntsuas qhov concentration ntawm cov khoom hauv huab cua. Qhov qis dua tus lej ISO, qhov tsawg dua tau tso cai rau hauv huab cua. ISO Class 1 yog qhov kev faib tawm huv tshaj plaws, thaum ISO Class 9 tso cai rau qhov siab tshaj particle concentration.
Lub tswv yim suab yooj yim, tab sis kev faib chav huv tuaj yeem ua rau tsis meej pem thaum koj xub pom cov ntsiab lus xws liISO 5, ISO 7, ISO 8, Class 100, lossis 0.5 µmnyob rau hauv ib tug specification.
Qhov tseem ceeb yog kom nkag siab tias tus lej ntsuas tau li cas.
TS EN ISO 14644-1: 2015 faib cov huab cua huv raws li qhov xav tau ntawm cov pa hauv huab cua ntawm qhov loj me me. Tus qauv txiav txim siab cov neeg particle nrog qhov loj me los ntawm0.1 µm 5 µmthiab siv cov khoom siv huab cua los txiav txim siab qhov sib npaug ntawm cov khoom sib npaug los yog loj dua li qhov loj me. Nws tsis cais cov khoom los ntawm seb lawv puas siv tau, lom neeg, tshuaj lom neeg, lossis lwm yam.
Dab tsi yog ISO Cleanroom Class Measure?
Ib chav kawm ISO cleanroom yog qhov tseem ceeb aparticle concentration txwv rau huab cua.
Rau txhua chav kawm ISO, tus qauv ntsuas qhov siab tshaj plaws ntawm cov khoom tso cai rau hauv ib lub cubic meter ntawm huab cua ntawm qhov loj me me.
Piv txwv li, ibISO Class 5cleanroom tso cai rau ntau tshaj3,520 particles ib cubic meter ntawm ntau dua los yog sib npaug rau 0.5 µm.
IbISO Class 7cleanroom tso cai mus txog352,000 particles per cubic meter ntawm ntau dua lossis sib npaug li 0.5 µm.
IbISO Class 8cleanroom tso cai mus txog3,520,000 particles ib cubic meter ntawm ntau dua los yog sib npaug rau 0.5 µm.
Qhov txawv yog qhov tseem ceeb. Ntawm qhov loj dua lossis sib npaug rau 0.5 µm qhov pib, ISO 8 tso cai 1,000 npaug ntawm cov particle concentration tso cai los ntawm ISO 5.
Qhov no muab txoj cai tseem ceeb tshaj plaws rau koj nyeem ISO kev faib tawm:
Qhov qis dua tus lej ISO, qhov tsawg dua qhov tso cai rau huab cua los particle concentration.
Qhov "Ntau dua lossis sib npaug rau 0.5 µm" txhais li cas?
Lub cimNtau dua lossis sib npaugtxhais tau tias "sib npaug los yog loj dua."
Yog li ntawd,Ntau tshaj lossis sib npaug li 0.5 µmtxhais tau hais tias cov khoom txee yog suav cov khoom uas yog 0.5 micrometers lossis loj dua, tsis suav cov khoom uas yog 0.5 µm.
Tib lub hauv paus ntsiab lus siv rau ntau dua lossis sib npaug ntawm 0.1 µm, Ntau dua lossis sib npaug 0.2 µm, Ntau dua lossis sib npaug rau 0.3 µm, Ntau dua lossis sib npaug rau 1 µm thiab Ntau dua lossis sib npaug li 5 µm.
Rau ISO Class 5, piv txwv li, qhov txwv ntawm Ntau dua lossis sib npaug ntawm 0.5 µm yog 3,520 qhov ib lub cubic meter, thaum qhov txwv ntawm Ntau dua lossis sib npaug rau 1 µm tsuas yog 832 qhov ib lub cubic meter.
Tus naj npawb tso cai yuav me dua li qhov particle - qhov loj me pib nce vim qhov kev ntsuas yog raws li qhov sib npaug ntawm qhov siab tshaj qhov pib.

Tsis yog txhua qhov particle - qhov loj me yog siv rau txhua chav ISO. Qhov loj me me ntawm cov khoom siv yog nyob ntawm cov chav kawm thiab cov lus qhia kev faib tawm raws li ISO 14644-1.
Dab tsi ISO Class yog Cleaner?
Tus lej qis ib txwm txhais tau hais tias qhov kev txwv nruj dua particle concentration.
Kev sib raug zoo tuaj yeem pom tau yooj yim:
ISO 5 → ISO 6 → ISO 7 → ISO 8
Raws li koj txav los ntawmISO 5 rau ISO 8, qhov tso cai pa particle concentration nce.
Piv txwv li:
|

Qhov no yog vim li cas hais tias chav tsev yog "ISO 8" tsis txhais hais tias nws huv dua li "ISO 5" chav. Qhov opposite yog muaj tseeb:ISO 5 muaj qhov nruj dua cov pa particle txwv.
Dab tsi yog qhov txawv ntawm ISO 5, ISO 7 thiab ISO 8?
Peb cov chav kawm no feem ntau ntsib hauv chav huv huv.
ISO Class 5
ISO 5 tso cai mus txog3,520 particles Ntau tshaj los yog sib npaug rau 0.5 µm ib cubic meter.
Nws sawv cev rau ib puag ncig nruj tswj hwm huab cua ntau dua li ISO 7 lossis ISO 8.
Lub sij hawm lausChav Kawm 100feem ntau txuam nrog rau qib no.
ISO Class 7
ISO 7 tso cai mus txog352,000 particles Ntau tshaj los yog sib npaug rau 0.5 µm ib cubic meter.
Nws tsis muaj kev txwv tsawg dua li ISO 5 tab sis huv dua li ISO 8.
Tus qubChav Kawm 10,000terminology feem ntau cuam tshuam nrog ISO 7.
ISO Class 8
ISO 8 tso cai mus txog3,520,000 particles Ntau tshaj los yog sib npaug rau 0.5 µm ib cubic meter.
Nws tso cai rau cov particle concentration ntau dua li ISO 5, 6, lossis 7 thiab yog li sawv cev rau qib qis dua ntawm kev huv huv.
Puas yog Class 100 zoo ib yam li ISO 5?
Chav Kawm 100 yog cov lus qub ntawm Tsoom Fwv Teb Chaws Standard 209E terminology feem ntau txuam nrog ISO Class 5.
Cov qub Tsoom Fwv Teb Chaws Standard 209E siv cov lus xws li Class 100, Class 1,000, Class 10,000 thiab Class 100,000. TS EN ISO 14644-1 Kev faib tawm txoj hauv kev nrog cov txheej txheem thoob ntiaj teb raws li cov pa hauv huab cua hauv cubic meters

Qhov no yog vim li cas tus neeg muag khoom tseem tuaj yeem piav qhia txog cov khoom lag luam lossis chaw ua haujlwm li "Class 100" txawm hais tias cov chav huv huv tam sim no tau sau ua ISO 5.Rau cov ntaub ntawv kev tshaj lij tam sim no, nws yog qhov zoo dua los qhia cov ntaub ntawv hais txog kev huv huv.ISO 14644-1 Kev faib tawmkom meej meej es tsis txhob cia siab rau cov laus terminology xwb.
ISO 14644-1 Tsis Qhia Koj Dab Tsi?
Ib chav kawm ISO piav qhia txog huab cua uas muaj qhov sib npaug. Nws uatsis yogmuab cov lus piav qhia tag nrho ntawm txhua yam mob hauv chav huv.
ISO 14644-1 tsis qhia koj:
- Txawm hais tias cov pa hauv huab cua yog cov kab mob uas siv tau
- Seb tus txheej txheem yog sterile
Qhov tseeb huab cua- hloov pauv yuav tsum muaj rau chav
Qhov kub los yog av noo yuav tsum tau
Ua tiav HVAC tsim
Qhov chaw huv huv ntawm cov khoom siv lossis cov khoom
Kev ua kom huv huv huv - txheej txheem tswj
Cov no yog cov kev txiav txim siab cais los ntawm lwm cov kev cai, cov qauv lossis cov txheej txheem tshwj xeeb.
Qhov kev sib txawv no tseem ceeb vimtus lej ISO yuav tsum tsis txhob raug kho raws li kev txhais ua tiav ntawm chav huv huv.
Piv txwv li, ISO 14644-1 tshwj xeeb hais tias nws tsis tuaj yeem siv los ua tus yam ntxwv ntawm lub cev, tshuaj lom neeg, hluav taws xob, siv tau lossis lwm yam xwm txheej ntawm huab cua.
Vim li cas tus lej ISO tseem ceeb
Cov chav kawm ISO muab ib txoj hauv kev los piav txog qhov huv ntawm huab cua.
Es tsis txhob hais tias ib chav yog "ntxhiab heev" thiab lwm qhov yog "tsawg dua huv," qhov kev faib tawm muab cov ntsuas particle concentration txwv.
Qhov ntawd ua rau cov chav kawm ISO muaj txiaj ntsig zoo thaum sib piv cov kev cai huv huv, tshuaj xyuas cov txiaj ntsig kev xeem, tsim cov chaw tswj hwm, thiab sib txuas lus tshwj xeeb ntawm cov tuam txhab thiab cov neeg yuav khoom.
Txoj hauv kev zoo tshaj plaws kom nco qab qhov system yog yooj yim:
ISO 1 yog qhov kev faib tawm huv tshaj plaws. ISO 9 yog qhov nruj tshaj plaws. Tus lej qis dua, cov pa tawm tsawg dua raug tso cai.
Thaum koj pomISO 5, ISO 7 lossis ISO 8, tsis txhob saib tsuas yog hauv chav kawm tus lej xwb. Kuj saib covKev ntsuas particle loj, qhov tso cai concentration, thiab cov kev sim ntsuas.
Thaum peb cov ntsiab lus meej meej, ISO 14644-1 kev faib tawm yuav nkag siab yooj yim dua.
