EN10210 yog dab tsi?

Cov txheej txheem European no qhia txog cov txheej txheem kev xa khoom rau kub tiav hollow seem ntawm cov ntawv ncig, square, duab plaub lossis elliptical thiab siv rau cov ntu hollow tsim kub, nrog lossis tsis muaj kev kho cua sov tom qab.

EN 10210 zoo ib yam rau BS EN 10210, tshwj tsis yog tias nws siv rau ntau lub tebchaws. Tag nrho cov kev cai hauv qab no kuj tseem siv tau rau BS EN 10210.
