Tus txheej txheem rau surge (kev tiv thaiv xob laim) yog dab tsi? Cov txiaj ntsig kev xeem raug txiav txim li cas?
Kev ntsuas hluav taws xob (kev tiv thaiv xob laim) yog: IEC6100-4-5, cov qib raws li hauv qab no

CEEB TOOM: X tuaj yeem yog ib theem, saum toj, hauv qab lossis nyob nruab nrab ntawm lwm qib. Cov qib no tuaj yeem teev nyob rau hauv cov qauv khoom. taw qhia.
Muaj plaub yam kev txiav txim rau kev xeem xeem:
1) Hluav taws xob tsis muaj kev cuam tshuam;
2) Kev ua haujlwm hluav taws xob qee zaus muaj kev ua haujlwm tsis sib xws, tab sis nws tuaj yeem teb tau;
3) Tsis txhob ua haujlwm, thiab nws tuaj yeem rov qab tau tom qab rov pib dua tom qab fais fab tuag;
4) Kev puas tsuaj.
