BS 1139 Cov Lus Cim Yuav Tsum Tau

Cov raj yuav tsum tau cim los ntawm kev zoo siab ntawm lub sijhawmtsis siab tshaj 1,5 m.

Qhov siab ntawm cov cim yuav tsum yog yam 4mm thiab impression ntawmtsawg kawg yog 0, 2 mm tob.

Lub cim yuav qhia

- lub npe lossis cov cim lag luam ntawm cov chaw tsim khoom siv raj;

- tus lej EN "39",

- tsab ntawv "A" lossis "B" rau cov ntsiab lus silicon raws li qhov tsim nyog;

- lub nominal phab ntsa thickness "4", uas yuav tsum tsis txhob muab tso rau tam sim ntawd nyob ib sab ntawm tus naj npawb "39".

Tom qab daim ntawv thov txheej tiv thaiv yuav tsum tau siv lub cim ntxiv rau cov hlab ntawm lub sijhawm tsis pub tshaj 1,5 m uas qhia lub npe lossis cov cim lag luam ntawm cov txheej txheem.
