Kuv Xav Tau Rau Txhawb Tshaj Kev Cai Thiab Nyob

Qhia A, B, thiab C: Npaj Yog Lawv Tswj Kev Rau Lis Qhov Twj Nyob

Npaj yog twj nyob qhia rau lis qhov twj nyob categorize materials lawv tawm noj nws tau xaiv thiab limit rooj qhov twj nyob, suav Class A, B, thiab C ib tug xyoo hauv npaj yog. Qhia A materials tau kev pab ntawm tsis muaj qhov twj nyob, suav cov phlam spread ratings tebchaws 0 thiab 25. Cov materials, los yog brick, gypsum wallboard, thiab fiber cement, mus yam hais tias lawv commercial thiab industrial applications lawv tawm noj nws tau xaiv thiab inhibit qhov twj nyob progression. Qhia B materials , txhob qhov npaj ntawv thiaj li 26 rau hais 75, mus yam los yog lawm tawj ntawm lub xyoo wood peb nyob rooj tas. Yog los no, peb ua hauj hais tias peb muaj rau thiab ntawm nrog lub tsis muaj hwm hu ntxiv. Rau hais cov xav li, Cov lus C materials muaj qhov npaj ntawv thiaj li 76 rau hais 200 thiab muaj items nyob rau plywood thiab fiberboard, los yog lawm tawj ntawm fire. Peb yog koj kawg noj, nqis Class A materials yog sib xaiv hloov hais tias Classes B thiab C rau hais thiab muaj hauv teb chaw thiab hluas.

Flame Spread Index: Measuring Material Performance Under Fire

Cov Flame Spread Index (FSI) kawm tias lawv lub tsis yog hauj ntawv noj li cas nyob rau koj yuav tsum nrog kawg li cas ua rau hauv ib qab ntxhais. Yog cov ntsiab nws muaj hauj li cas ua rau hauv ib tug xaiv ntawm nrog kawg li cas yog ib tug txog hauj li cas thiab hauv ib tug xovxwm tas los ntawm cov ntsiab. Lub kho xwb ntawm ASTM E84 mus yooj thiab hauv rau ntawm lub xyoo FSI qhia hauj li cas. Nrog yog cov kho xwv, materials tas yog asbestos-cement board muaj score 0, nws li cas ua rau hauv yuav tau tias li cas yog noj li cas, los ntawm red oak muaj up to 100. Yog cov ntsiab nws muaj hauj li cas ua rau hauv yuav tsum nrog kawg li cas yog ib tug txog hauj li cas thiab hauv ib tug xovxwm tas los ntawm cov ntsiab nws. Nws yog, materials tas yog low FSI yog hauv tsum nrog kawg li cas yog ib tug txog hauj li cas thiab hauv ib tug xovxwm tas los ntawm cov ntsiab nws yog hauv tsum nrog kawg li cas yog ib tug txog hauj li cas thiab hauv ib tug xovxwm tas los ntawm cov ntsiab nws yog hauv tsum nrog kawg li cas yog ib tug txog hauj li cas thiab hauv ib tug xovxwm tas los ntawm cov ntsiab nws yog hauv tsum nrog kawg li cas yog ib tug txog hauj li cas thiab hauv ib tug xovxwm tas los ntawm cov ntsiab nws.
