Basic Mandatory National StandardGB 8624-2012 Classification for Burning Behavior of Building Materials and ProductsUnified "Benchmark": Qhia cov qhab nia kev sib koom ua ke rau txhua yam khoom siv hauv tsev (xws li cov ntawv hollow).Raws li tus qauv yuav tsum tau ua, txhua yam khoom muaj feem xyuam yuav tsum ua raws li nws cov kev ntsuas ntsuas. Nws ua lub hauv paus tseem ceeb rau cov qauv khoom.
Cov Khoom Siv Tshwj Xeeb
General Standards (xws li GB/T XXXXX)
Kev lag luam Standards (piv txwv li, JG/T 116)
Khoom "Specification Manual": Rau cov ntawv tshwj xeeb ntawm cov ntawv hollow (xws li polycarbonate PC hollow sheets), nws qhia tag nrho cov kev cai, thiab cov ntaub ntawv GB 8624 kom paub meej cov nplaim hluav taws kub. Los ntawm kev xa mus thiab tso siab rau GB 8624, lawv ua ke tsim cov khoom lag luam tiav.
Tub ntxhais: Yuav tsum tau National Standard GB 8624
Qhov no yog ib qho tseem ceeb thiab yuav tsum tau muab faib ua tus qauv rau kev combustion kev ua tau zoo ntawm tag nrho cov khoom siv tsev (xws li hollow sheets). Nws tsis qhia meej yuav ua li cas los tsim cov khoom siv tshwj xeeb, tab sis txhais tau tias "kev sib koom ua ke".
Kev faib tawm: Raws li qhov nyuaj ntawm combustion, cov ntaub ntawv feem ntau muab faib ua plaub qib los ntawm siab tshaj mus rau qis tshaj: Qib A (tsis yog-combustible), Qib B1 (nplaim-retardant), Qib B2 (combustible), thiab Qib B3 (flammable). Cov feem ntau hu ua "flame-cov ntawv hollow retardant" feem ntau yog xa mus rau cov khoom uas ua tau raws li qib B1 lossis siab dua.
Muaj nuj nqi: Rau ib daim ntawv hollow uas thov kom muaj nplaim taws -cov khoom siv hluav taws xob, kev ntsuas thiab ntsuas ntawm nws cov nplaim taws- kev ua haujlwm tsis zoo yuav tsum tau ua raws li tus qauv no. Piv txwv li, tus qauv qhia tias cov neeg muab khoom siv yuav tsum tau muab daim ntawv pov thawj qib kev sib xyaw ua ke uas tau muab los ntawm lub koom haum thib peb - tog xeem.
