Cov ntsiab lus ntawm cov kev hloov pauv tseem ceeb vs EN 388: 2003
- Abrasion: daim ntawv abrasion tshiab yuav raug siv rau ntawm qhov kev sim
- Kev cuam tshuam: txoj kev sim tshiab (ua tsis tiav: F lossis dhau rau thaj chaw thov kev tiv thaiv kev cuam tshuam)
- Txiav: tshiab EN ISO 13997, tseem hu ua TDM-100 xeem txoj kev. Kev xeem txiav yuav raug muab qhab nia nrog tsab ntawv A rau F rau cov hnab looj tes tiv thaiv
- Lub cim tshiab nrog 6 qib kev ua haujlwm
Vim li cas ib txoj kev txiav txiav tshiab?
Lub Coup Test khiav mus rau hauv cov teeb meem thaum kuaj cov ntaub ntawv xws li high-perform mance fabrics raws li cov ntaub ntawv iav fiber los yog stainless hlau, tag nrho cov uas muaj ib tug dulling nyhuv ntawm cov hniav. Yog li ntawd, qhov kev ntsuam xyuas tuaj yeem ua rau muaj qhov tsis raug, muab qhov kev txiav txiav uas tsis yog qhov qhia tau tseeb ntawm qhov kev txiav tawm tiag tiag ntawm cov ntaub. Txoj kev xeem TDM-100 yog tsim los ua kom zoo dua simulate qhov xwm txheej hauv ntiaj teb xws li kev sib tsoo lossis kev sib tsoo.
Rau cov ntaub ntawv uas tau pom tias npub cov hniav thaum lub sij hawm pib qhov kev xeem ua ntu zus hauv Coup Test, EN388: 2016 tshiab, yuav hais EN ISO 13997 qhab nia. Los ntawm qib A mus rau qib F.
