International Standards rau PPR Yeeb Fittings
ISO Standards
Lub koom haum International rau Standardization (ISO) tau tsim ntau yam qauv ntsig txog PPR yeeb nkab fittings. TS EN ISO 15874 Cov qauv tseem ceeb tshaj plaws, npog cov kav dej ua los ntawm polypropylene. Cov qauv no qhia txog qhov yuav tsum tau ua rau PPR kav thiab fittings, nrog rau qhov ntev, cov ntaub ntawv, kev ua tau zoo, thiab cov qauv kev sim. Kev ua raws li ISO 15874 kom ntseeg tau tias PPR fittings yog tsim los rau cov qauv zoo thiab cov qauv zoo.
DIN Standards
Lub koom haum German rau Standardization (DIN) muab cov qauv ntxiv rau PPR yeeb nkab fittings. DIN 8077 thiab DIN 8078 yog cov qauv tseem ceeb rau qhov ntev thiab cov kev xav tau zoo ntawm PPR kav thiab fittings. Cov qauv no tau lees paub dav dav thiab feem ntau hais txog kev lag luam nyob sab Europe, kom ntseeg tau tias cov khoom ua tau raws li cov qauv ntsuas zoo.
National Standards
ASTM Txuj
Hauv Tebchaws Meskas, American Society for Testing and Materials (ASTM) muab cov qauv rau ntau yam khoom siv, suav nrog PPR. ASTM F2389 yog tus qauv tseem ceeb rau kev ntsuas siab-rated polypropylene (PP) piping systems. Nws suav nrog cov khoom siv tshwj xeeb, qhov ntev, thiab kev ua haujlwm, kom ntseeg tau tias PPR fittings siv hauv Teb Chaws Asmeskas ua tau raws li cov qauv nruj thiab kev nyab xeeb.
BS Standards
British Standards (BS) kuj tseem cuam tshuam rau PPR yeeb nkab fittings. BS 6920, piv txwv li, ntsuas qhov tsim nyog ntawm cov khoom tsis yog xim hlau siv rau kev sib cuag nrog dej npaj rau tib neeg noj. Kev ua raws li tus qauv no ua kom ntseeg tau tias PPR fittings muaj kev nyab xeeb rau kev siv dej haus, qhov tseem ceeb rau cov kav dej.
Daim Ntawv Pov Thawj
WRAS Certification
Daim Ntawv Qhia Txog Kev Tswj Dej (WRAS) daim ntawv pov thawj yog qhov tseem ceeb rau txhua yam khoom siv kav dej siv hauv UK. PPR yeeb nkab fittings nrog WRAS kev pom zoo tau raug kuaj thiab ntawv pov thawj raws li UK cov cai tswj dej. Daim ntawv pov thawj no ua kom ntseeg tau tias cov fittings tsis paug cov dej thiab tsim nyog rau kev siv hauv cov dej haus.
NSF daim ntawv pov thawj
Cov ntawv pov thawj National Sanitation Foundation (NSF) yog qhov tseem ceeb rau cov khoom siv hauv cov dej haus hauv North America. NSF / ANSI 14 thiab NSF / ANSI 61 yog cov qauv tsim nyog rau cov kav dej yas. PPR fittings nrog NSF ntawv pov thawj tau raug sim rau kev noj qab haus huv thiab kev ua haujlwm, kom ntseeg tau tias lawv muaj kev nyab xeeb rau kev siv hauv cov dej haus.
Kev Tswj Xyuas Kev Tswj Xyuas Zoo
ISO 9001 Cov
ISO 9001 daim ntawv pov thawj yog ib qho kev lees paub thoob ntiaj teb rau cov txheej txheem kev tswj hwm zoo. Cov neeg tsim khoom ntawm PPR yeeb nkab fittings nrog ISO 9001 ntawv pov thawj qhia lawv txoj kev cog lus los tswj cov txheej txheem tsim khoom zoo thiab kev txhim kho txuas ntxiv. Cov ntawv pov thawj no ua rau cov neeg siv khoom paub tseeb tias cov fittings raug tsim nyob rau hauv kev tswj xyuas zoo.
ISO 14001 Daim Ntawv Pov Thawj
ISO 14001 daim ntawv pov thawj muaj feem xyuam rau kev tswj hwm ib puag ncig. PPR haum cov tuam txhab nrog cov ntawv pov thawj no tau cog lus los txo qis lawv qhov cuam tshuam ib puag ncig. Daim ntawv pov thawj no tseem ceeb zuj zus vim tias kev ruaj khov ua ib qho tseem ceeb hauv kev tsim kho thiab cov kav dej.
Xaus
PPR yeeb nkab fittings yuav tsum ua raws li ntau yam qauv thiab ntawv pov thawj los xyuas kom meej tias lawv zoo, kev nyab xeeb, thiab kev ua tau zoo. Cov qauv thoob ntiaj teb xws li ISO 15874, cov qauv hauv tebchaws xws li ASTM F2389, thiab cov ntawv pov thawj los ntawm lub cev zoo li WRAS thiab NSF ua lub luag haujlwm tseem ceeb hauv kev lees paub qhov kev ntseeg tau ntawm PPR fittings. Tsis tas li ntawd, cov ntawv pov thawj kev tswj xyuas zoo xws li ISO 9001 thiab ISO 14001 ntxiv txhim khu kev ntseeg tau thiab kev lag luam lees paub ntawm cov khoom no. Kev nkag siab thiab ua raws li cov qauv no thiab cov ntawv pov thawj yog qhov tseem ceeb rau cov tuam txhab, cov neeg cog lus, thiab cov neeg siv kawg kom ntseeg tau tias kev ua tiav ntawm fernco kav dej PPR yeeb nkab fittings hauv cov kav dej.
