Raws li kev txhim kho hauv zej zog, ntau thiab ntau tus neeg tau txais kev pab los ntawm ntau lub khw saib xyuas cov neeg hauv tsev neeg kev noj qab haus huv thiab kev nyab xeeb thaum xaiv cov khoom siv ntoo yas sib xyaw.Ntawm ib sab, peb tsom mus rau cov khoom sib xyaw nws tus kheej kom paub tseeb tias nws yog cov khoom ntsuab thiab muaj kev nyab xeeb thiab ntawm qhov tod tes, peb mob siab txog yog tias nws tuaj yeem tiv thaiv peb ntawm lwm yam kev puas tsuaj xws li hluav taws.
Hauv EU, kev faib hluav taws xob ntawm cov khoom tsim kho thiab cov khoom siv hauv tsev yog EN 13501-1: 2018, uas tau lees txais hauv txhua lub tebchaws EC.
Txawm hais tias qhov kev faib tawm yuav raug lees txais thoob plaws Tebchaws Europe, nws tsis tau txhais hais tias koj yuav siv tau ib yam khoom nyob rau hauv tib qhov chaw los ntawm lub teb chaws mus rau lub teb chaws, raws li lawv cov kev thov tshwj xeeb tej zaum yuav txawv, qee qhov xav tau B theem, thaum qee qhov yuav xav tau cov khoom siv. mus txog qib A.
Yuav kom paub meej ntxiv, muaj cov flooring thiab cladding seem.
Rau hauv pem teb, tus qauv xeem feem ntau ua raws EN ISO 9239-1 los txiav txim qhov kev tso tawm hluav taws xob tseem ceeb thiab EN ISO 11925-2 Kev Tshaj Tawm = 15s kom pom cov nplaim taws kis qhov siab.
Thaum rau cladding, qhov kev ntsuam xyuas tau ua raws li EN 13823 los soj ntsuam cov peev txheej ntawm cov khoom lag luam rau kev tsim hluav taws kub, nyob rau hauv qhov teeb meem hluav taws kub simulating ib qho hluav taws kub nyob ze ntawm cov khoom.Ntawm no yog ob peb yam, xws li hluav taws kev loj hlob tus nqi, pa luam yeeb loj hlob tus nqi, tag nrho cov pa luam yeeb thiab kub tso nyiaj thiab lwm yam.
Tsis tas li ntawd, nws yuav tsum tau ua raws li EN ISO 11925-2 Kev Tiv Thaiv = 30s zoo li kev sim hauv pem teb yuav tsum tau kuaj xyuas cov nplaim taws kis qhov siab.
Teb chaws USA
Rau Asmeskas kev lag luam, qhov kev thov tseem ceeb thiab kev faib tawm rau hluav taws kub retardant yog
International Building Code (IBC):
Chav Kawm A: FDI 0-25; SDI 0-450;
Chav Kawm B: FDI 26-75; SDI 0-450;
Chav Kawm C: FDI 76-200; SDI 0-450;
Thiab kev xeem raug ua raws li ASTM E84 los ntawm Tunnel apparatus.Flame Spread Index thiab Smoke Development Index yog cov ntaub ntawv tseem ceeb.
Tau kawg, rau qee lub xeev, xws li California, lawv muaj lawv qhov kev thov tshwj xeeb ntawm cov pov thawj ntawm sab nrauv hluav taws kub.Yog li no yog tsim los nyob rau hauv lub lawj nplaim taws kuaj raws li California Referenced Standards Code (Tshooj 12-7A).
AUS BUSHFIRE ATTACK LEVEL (BAL)
AS 3959, Tus Qauv no muab txoj hauv kev los txiav txim siab qhov kev ua haujlwm ntawm cov khoom siv sab nraud thaum raug tshav kub kub, hlawv embers thiab hlawv cov khib nyiab.
Muaj 6 qhov kev tua hluav taws tua hluav taws hauv tag nrho.
Yog tias koj xav paub ntau ntxiv txog txhua qhov kev xeem lossis kev thov kev lag luam, thov koj xav tiv tauj peb.
