Tus qauv specifications feem ntau siv rau braided hoses yog GB/T 23448-2009 los yog JC 886-2001. Txij li cov hoses no feem ntau yog siv rau kev sib txuas ntawm cov dej hauv cov khoom siv tu cev lossis cov dej haus-qhov twg cov dej, tom qab dhau los ntawm lub hose, tuaj rau hauv kev sib cuag nrog tib neeg cov tawv nqaij los yog noj ncaj qha-cov khoom siv rau hauv lub raj (uas yog nyob rau hauv kev sib cuag nrog cov dej qhov chaw) yog qhov tseem ceeb heev.
Cov qauv hauv teb chaws tam sim no thiab Ministry of Construction cov qauv tswj hwm tias cov khoom siv hauv lub raj yuav tsum ua raws li GB / T 17219-1998, * Tus Qauv rau Kev Ntsuam Xyuas Kev Nyab Xeeb ntawm Cov Khoom Siv thiab Cov Khoom Siv Tiv Thaiv hauv Kev Siv Dej Haus thiab Kev faib Khoom *, txhawm rau xyuas kom meej tias cov dej hauv av tseem tsis muaj paug.
Hauv Tebchaws Europe, Lub Tebchaws Yelemees tau tsim cov kev cai nruj tshwj xeeb ntawm cov hoses braided-tshwj xeeb yog cov kev txuas nrog cov khoom siv dej haus-tsim kom cov raj sab hauv tau txais W270 microbiological toxicity test. Raws li qhov yuav tsum tau ua nruj me ntsis, cov khoom siv raw li PVC thiab EPDM tsis suav tias yog ua raws. Yog li ntawd, cov ntaub ntawv hauv lub raj tshiab kawg uas tau siv dav hauv European lag luam feem ntau yog silicone lossis PEX-B tubing. Muab tus nqi siab ntawm silicone tubing, PEX-B tubing tau tshwm sim los ua qhov tseem ceeb tshaj plaws rau yav tom ntej ntawm European lag luam- ib qho qauv uas tseem txuas ntxiv mus rau lwm lub tebchaws tsim, suav nrog cov hauv North America.
