I. Kev Npaj Ua Qauv
1.Txoj kev kuaj tus neeg sawv cev: Cov qauv yuav tsum raug txiav los ntawm cov khoom sib txawv ntawm cov kaus mom los nag (xws li lub sab sauv, ncej, thiab hauv ob sab phlu) thiab cov khoom sib txawv kom ntseeg tau tias cov txiaj ntsig tau sawv cev ntawm tag nrho cov khoom.
2.Precise Dimensions thiab Quantity: Txiav cov qauv kuaj nruj me ntsis raws li qhov ntev (xws li qhov ntev thiab qhov dav) teev nyob rau hauv tus qauv, thiab npaj kom muaj nuj nqis txaus (feem ntau tsawg kawg yog 5 cov qauv siv tau rau ib pawg) kom txo tau qhov yuam kev.
3.Preprocessing: Ua ntej kuaj, cov qauv yuav tsum conditioned nyob rau hauv tus txheej txheem kub thiab av noo ib puag ncig (xws li, kub 20 ± 2 degree, txheeb ze humidity 65 ± 4%) rau tsawg kawg yog 24 teev kom tshem tawm ib puag ncig cuam tshuam.
II. Test Ib puag ncig thiab kev ua haujlwm
1.Strict Environmental Control: Ua qhov kev ntsuam xyuas nyob rau hauv lub siab tsis muaj cua combustion xeem chamber kom ruaj khov huab cua.
2.Flame Calibration: Siv cov pa roj carbon monoxide (xws li methane, propane) thiab kho cov nplaim taws qhov siab thiab siv kom tau raws li cov qauv kev cai.
3.Standardized Kev Ua Haujlwm: Xyuas kom meej tias cov nplaim taws ua haujlwm ntawm txoj haujlwm tau teev tseg kom raug thiab ruaj khov (piv txwv li, qhov nruab nrab ntawm cov hauv qab hauv txoj kev ntsug), thiab nruj me ntsis sau lub sijhawm.
III. Kev nyab xeeb thiab cov ntaub ntawv
1.Full-Kev Tiv Thaiv Txheej Txheem: Cov neeg ua haujlwm yuav tsum hnav cov cuab yeej tiv thaiv thiab ua haujlwm hauv lub hood fume los yog qhov chaw nruab nrog lub tshuab pa.
2.Kev soj ntsuam thiab cov ntaub ntawv: Ntxiv nrog rau kev sau cov ntaub ntawv tseem ceeb, cov xwm txheej xws li dej ntws, pa taws, tsw ntxhiab, thiab qhov shrinkage yuav tsum tau soj ntsuam thiab sau tseg.
3.Standardized pov tseg: Tom qab kev sim, cov qauv kuaj yuav tsum raug tua kom tiav, thiab cov seem yuav tsum muab pov tseg kom zoo.
Thaum ua qhov kev ntsuam xyuas kev sib tsoo ntawm cov khau nag los nag (feem ntau yog cais raws li "cov khau roj hmab"), qhov kev ceev faj tseem ceeb yog ua raws li lub teb chaws tus qauv. Raws li lub teb chaws tus qauv GB / T 35497-2017 《Test Methods for Flame Retardant Properties of Materials Used in Rubber Shoes》.
