Lub tswv yim ntawm Nplaim Retardant Rating

Flame retardant rating testing yog ib txoj hauv kev siv los ntsuas cov khoom muaj peev xwm tiv taus cov nplaim taws. Cov qauv zoo xws li UL94, IEC 60695-11-10, thiab GB / T 5169.16. Nyob rau hauv tus qauv UL94,Kev sim rau Flammability ntawm cov ntaub ntawv yas rau cov khoom siv hauv cov khoom siv thiab cov khoom siv, nplaim retardant kev ntsuam xyuas tau muab faib ua 12 qib raws li qhov kev ntsuas qhov nruj thiab daim ntawv thov: HB, V-2, V-1, V-0, 5VA, 5VB, VTM-0, VTM-1, VTM-2, HBF, HF1, thiab HF2.

Feem ntau, feem ntau siv cov nplaim hluav taws kub nyhiab ntawm V-0 txog V-2, nrog V-0 qhia txog qhov ua tau zoo tshaj plaws ntawm cov nplaim hluav taws.

1.1 Cov ntsiab lus ntawm Plaub Nplaim Retardant Ratings
