ISO 9239, ASTM E648, NFPA 253 thiab ASTM D 2859 yog cov qauv sib txawv ntawm daim ntawv thov thiab cov txheej txheem kev sim hauv kev ntsuas hluav taws thiab cov khoom siv kev nyab xeeb, thiab muaj qee qhov kev sib raug zoo ntawm lawv, tab sis lawv tsis sib npaug lossis lwm yam.
ISO 9239 Kev Tswj Xyuas Kev Lag Luam
Scope ntawm daim ntawv thov: ISO 9239 cuam tshuam nrog kev sim ntawm cov ntaub pua tsev rau lawv cov lus teb rau hluav taws, tshwj xeeb tshaj yog kev txiav txim siab ntawm lawv tus cwj pwm kub siv txoj kev tshav kub kub. Nws muaj feem xyuam rau ntau yam ntaub ntawv hauv pem teb, xws li ntoo flooring, yas ntoo flooring, roj hmab flooring, txhua hom ntaub pua plag, thiab lwm yam.
Cov ntsiab lus ntawm tus qauv: ISO 9239 muaj ntau qhov chaw, ntawm qhov ISO 9239-1 feem ntau yog siv rau kev txiav txim siab ntawm tus cwj pwm combustion ntawm cov ntaub pua plag hauv qab qhov kev txiav txim ntawm qhov chaw tshav kub.
ASTM E 648 Cov Lus Qhia
Scope ntawm Daim Ntawv Thov: ASTM E648 yog tus qauv luam tawm los ntawm American Society for Testing and Materials (ASTM) rau kev txiav txim siab qhov hluav taws kub ntawm cov txheej txheem hauv pem teb (xws li panels, vuas thiab npog) thaum raug tshav kub kub.
Test Method: Cov txheej txheem suav nrog cov kauj ruam rau kev npaj cov qauv, kev teeb tsa kev sim ntsuas, ntsuas hluav taws xob thiab cov ntaub ntawv txheeb xyuas los ntsuas qhov ua tau zoo ntawm cov khoom siv hauv pem teb los ntawm kev suav cov hluav taws xob tseem ceeb.
Kev sib raug zoo ntawm kev sib raug zoo: ASTM E648 zoo ib yam li ISO 9239 raws li cov hom phiaj kev xeem, ob qho tib si tsom rau kev ua haujlwm ntawm cov khoom siv hauv pem teb, tab sis cov qauv kev sim thiab cov kev qhia tshwj xeeb yuav txawv. Qee qhov xwm txheej, ob tus qauv yuav raug xa mus rau ib leeg lossis siv ua ntxiv.
PAB 253
Scope ntawm Daim Ntawv Thov: NFPA 253 yog tus qauv muab los ntawm National Fire Protection Association (NFPA), tshwj xeeb tshaj yog rau qhov tseem ceeb radiant flux testing of floor coverings, kuj siv cov radiant heat source method.
Benchmarking: NFPA 253 muaj qee qhov sib tshooj nrog ISO 9239 thiab ASTM E648 hais txog kev sim txheej txheem thiab kev siv thaj chaw, ob qho tib si ntsuas kev ua haujlwm ntawm cov ntaub pua tsev hauv hluav taws. Txawm li cas los xij, NFPA 253 tuaj yeem tsom mus rau kev soj ntsuam kev ua tau zoo hauv qhov xwm txheej hluav taws kub tiag tiag thiab muaj cov kev xav tau tshwj xeeb.
ASTM D 2859 (Tshooj 2859)
Scope: ASTM D 2859 hais txog kev ntsuas hluav taws kub ntawm cov ntaub pua tsev hauv tsev thiab piav qhia txog txoj hauv kev rau kev txiav txim siab qhov flammability ntawm cov ntaub pua tsev tiav thaum raug rau qhov hluav taws kub nyob rau hauv cov chaw kuaj mob.
Benchmarking: ASTM D 2859 yog tsom rau kev ntsuas qhov hluav taws kub ntawm cov ntaub pua plag hauv pem teb ntau dua li ISO 9239, ASTM E648, thiab NFPA 253. Txawm hais tias txoj kev xeem yuav txawv, lawv txhua tus tau tsim los xyuas kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom hauv hluav taws.
Hauv cov ntsiab lus, ISO 9239, ASTM E648, NFPA 253 thiab ASTM D 2859 muaj lawv tus kheej cov yam ntxwv thiab kev siv dav hauv kev kuaj hluav taws thiab khoom siv kev nyab xeeb. Muaj qee qhov kev sib raug zoo ntawm lawv, tab sis lawv tsis sib npaug los yog lwm txoj hauv kev. Hauv kev siv tswv yim, cov qauv xeem tsim nyog yuav tsum raug xaiv rau kev ntsuam xyuas raws li cov kev xav tau tshwj xeeb thiab hom khoom siv.
