4. Kev ntsuas kev ua haujlwm sealing
Sau lub khob thermos nrog 50% ntawm qhov ntim ntawm cov dej kub siab tshaj 90 ℃, kaw nws nrog lub hau qub (plug), thiab viav vias nws nce thiab nqis 10 zaug ntawm qhov zaus ntawm 1 zaug / thib ob thiab amplitude ntawm 500mm los xyuas rau cov dej ntws
5. Kev tshuaj xyuas cov khoom sib khi thiab cov dej kub tsis zoo
Nws yog ib qho tsim nyog los xyuas kom meej tias cov khoom siv xws li cov hlua khi thiab cov hlua khi siv cov khoom noj khoom haus silicone thiab tsis muaj ntxhiab tsw.
6. Ua raws li cov qauv thoob ntiaj teb
EU kev ua lag luam yuav tsum tau ua raws li CE daim ntawv pov thawj, suav nrog kev tshuaj xyuas cov khoom lag luam, kev ntsuas thermal rwb thaiv tsev, kev ntsuas kev ua haujlwm txias, thiab lwm yam.
Tebchaws Asmeskas kev lag luam yuav tsum ua raws li FDA cov qauv los xyuas kom meej cov khoom muaj kev nyab xeeb ntawm stainless hlau thermos khob
7. Ua raws li kev kos npe thiab daim ntawv lo
Tom qab tau txais daim ntawv pov thawj CE, koj yuav tsum tau muab cov cim CE rau cov khoom siv thermos thiab xyuas kom meej tias cov ntim khoom sab nraud thiab daim ntawv lo ntawm cov khoom ua raws li cov cai thiab cov qauv.
