Cov dej haus nyab xeeb yog qhov tseem ceeb rau txhua lub tsev thiab kev lag luam. Yog li, nws yog ib qho tseem ceeb uas koj tuaj yeem yooj yim qhia koj cov khoom siv kav dej ua raws li cov cai.
WRAS, uas sawv cev rau Cov Txheej Txheem Qhia Txog Dej, yog cov ntawv pov thawj uas qhia tau tias ib yam khoom ua tau raws li cov qauv siab uas tau teev tseg los ntawm cov cai dej.
Cov Txheej Txheem Kev Pom Zoo Dej yog ib lub koom haum ywj pheej UK ntawv pov thawj rau cov khoom siv thiab cov kav dej, pab cov lag luam thiab cov neeg siv khoom xaiv cov khoom ua raws li cov dej nyab xeeb.
Daim ntawv pov thawj WRAS suav nrog cov ntaub ntawv pov thawj thiab cov khoom pov thawj.
1. Cov ntaub ntawv pov thawj
Kev soj ntsuam ntawm cov ntaub ntawv pov thawj suav nrog tag nrho cov ntaub ntawv uas tuaj rau hauv kev sib cuag nrog dej, xws li cov kav dej, faucets, valve Cheebtsam, cov khoom siv roj hmab, plastics, thiab lwm yam. Cov ntaub ntawv uas yuav siv tau rau hauv kev tsim cov khoom muaj feem xyuam yuav tsum ua raws li British BS6920 los yog BS5750 PART Standards.Yog cov ntaub ntawv tsis yog xim hlau ua raws li cov kev cai ntawm BS6920: 2000 (qhov tsim nyog ntawm cov khoom tsis yog xim hlau rau kev siv dej hauv kev sib cuag nrog tib neeg raws li lawv cov kev cuam tshuam rau cov dej zoo), lawv tuaj yeem raug lees paub los ntawm WRAS.
Kev kuaj cov khoom xav tau los ntawm WRAS yog raws li hauv qab no:
A. Cov ntxhiab thiab saj ntawm cov dej nyob rau hauv kev sib cuag nrog cov khoom yuav tsis hloov
B. Cov tsos ntawm cov khoom nyob rau hauv kev sib cuag nrog dej yuav tsis hloov
C. Yuav tsis ua rau kev loj hlob thiab yug me nyuam ntawm cov kab mob hauv dej
D. Cov hlau tsis muaj tshuaj lom yuav tsis ua rau nag lossis daus
E. Yuav tsis muaj lossis tso cov tshuaj uas cuam tshuam rau pej xeem kev noj qab haus huv
Kev ntsuam xyuas cov ntaub ntawv yuav tsum tau ntawv pov thawj, txwv tsis pub kev kuaj tshuab tsis tuaj yeem ua tiav ntawm tag nrho cov khoom. Los ntawm kev dhau qhov kev ntsuam xyuas qib, cov neeg siv khoom uas xav kom cov khoom ua tau raws li cov qauv tsim nyog tuaj yeem ntseeg tau tias cov khoom yuav tsis ua rau cov dej siv, kev tsim txom, kev siv tsis raug, lossis kev ua qias tuaj - plaub txoj cai ntawm dej.
2. Cov khoom pov thawj
Cov khoom siv kho tshuab ntawm cov khoom raug kuaj raws li ntau yam European thiab Askiv cov qauv thiab cov cai tswj xyuas cov lus qhia tshwj xeeb raws li cov khoom lag luam.
Npauj npaim li qub thiab kos li qub raug kuaj raws li EN12266-1, Resilient seated li qub nrog xoom leakage ntawm ob qho tib si kev ntsuas kev ua haujlwm siab thiab Hydrostatic siab kuaj.
