JIS 3444 STK290 Cov Hlau Hlau Khoom Yeeb Nkab Kev Siv Txoj Kev
Txoj kev tsim khoom yuav tsum muaj raws li hauv qab no:
A) cov raj yuav tsum yog tsim los ntawm kev sib xyaw ua ke ntawm lub raj tsim kev tsim qauv raj thiab cov txheej txheem ua tiav qhia nyob rau hauv cov lus 1.
B) cov tubes yuav ua tau siv coated steel ntawv lossis coated steel sawb, yog tias yog li thov los ntawm tus neeg yuav khoom.
c) Bevel kawg tau ua tiav tej zaum yuav tau siv nyob rau hauv tus neeg yuav khoom ntiag tug, uas tus neeg yuav khoom yuav tsum ua raws li cov khw muag khoom thiab tus neeg yuav khoom. Txawm li cas los xij, yog tias tsis muaj kev tshwj xeeb ntawm cov duab, nws yuav tsum raws li Daim Duab1.
