Cov qauv kev nyab xeeb thoob ntiaj teb cov khoom ua si

ISO (International Organization for Standardization) yog ib lub koom haum thoob ntiaj teb rau Standardization (ISO koom haum koom haum). Kev tsim qauv ntawm cov qauv thoob ntiaj teb feem ntau yog ua los ntawm ISO technical committees. Tom qab ua tiav, daim qauv qauv yuav tsum tau nthuav tawm ntawm cov tswv cuab ntawm Pawg Neeg Saib Xyuas Kev Xaiv Tsa, thiab tsawg kawg 75% ntawm cov pov npav yuav tsum tau txais ua ntej nws tuaj yeem raug tshaj tawm raws li tus qauv thoob ntiaj teb. Cov txheej txheem thoob ntiaj teb ISO8124 tau tsim los ntawm ISO / TC181, Pawg Neeg Ua Haujlwm ntawm Cov Khoom Ua Si Kev Nyab Xeeb.

a

ISO8124 suav nrog cov hauv qab no, lub npe dav dav yog cov khoom ua si kev nyab xeeb:

Part 1: Mechanical and Physical Performance Safety Standard
ISO8124 Cov qauv tshiab tshaj plaws ntawm ntu ntawm tus qauv no yog ISO 8124-1: 2009, hloov kho xyoo 2009. Cov kev cai hauv ntu no siv rau txhua yam khoom ua si, uas yog, txhua yam khoom lossis cov khoom tsim los yog qhia meej lossis npaj rau kev ua si los ntawm menyuam yaus hnub nyoog qis dua 14 xyoos.

Tshooj lus no qhia txog cov qauv tsim nyog rau cov yam ntxwv ntawm cov khoom ua si, xws li sharpness, loj, zoo, clearance (piv txwv li, suab, me me qhov chaw, ntse thiab ntse npoo, pob khawm clearance), raws li zoo raws li cov qauv siv tau rau ntau yam tshwj xeeb ntawm cov khoom ua si. (xws li, siab tshaj plaws kinetic zog ntawm projectiles nrog inelastic xaus, yam tsawg kawg nkaus lub kaum sab xis ntawm tej yam khoom ua si caij).

Tshooj lus no qhia txog cov khoom ua si uas yuav tsum tau ua thiab kev sim rau txhua pawg hnub nyoog ntawm cov menyuam yaus txij thaum yug txog rau 14 xyoo.

Qhov no tseem xav tau cov lus ceeb toom tsim nyog thiab cov lus qhia ntawm qee yam khoom ua si lossis lawv ntim khoom. Cov ntawv ntawm cov lus ceeb toom thiab cov lus qhia no tsis tau teev tseg vim hais tias cov lus sib txawv ntawm cov teb chaws, tab sis cov kev cai dav dav tau muab rau hauv Daim Ntawv Ntxiv C.

Tsis muaj ib yam dab tsi hauv nqe lus no tau qhia los npog lossis suav nrog qhov muaj feem cuam tshuam ntawm cov khoom ua si tshwj xeeb lossis hom khoom ua si uas tau txiav txim siab. Piv txwv 1: Ib qho piv txwv ntawm kev raug mob ntse yog kev sib deev ntawm rab koob. Kev puas tsuaj koob tau raug lees paub los ntawm cov neeg yuav khoom ntawm cov khoom ua si xaws, thiab kev raug mob ntse raug ceeb toom rau cov neeg siv los ntawm kev kawm ib txwm muaj, thaum cov cim ceeb toom raug cim rau ntawm cov khoom ntim.
Piv txwv 2: Cov koob txhaj tshuaj lom neeg kuj muaj kev siv cuam tshuam thiab lees paub kev puas tsuaj (xws li: tsis muaj kev ruaj ntseg thaum siv, tshwj xeeb tshaj yog rau cov pib tshiab) nrog cov yam ntxwv ntawm kev puas tsuaj (ntse ntug, clamping kev puas tsuaj, thiab lwm yam), raws li ISO8124 tus qauv no. ntawm cov kev xav tau yuav tsum raug txo kom tsawg kawg nkaus.

Ntu 2: Flammability
Daim ntawv tshaj tawm tam sim no ntawm ntu no ntawm ISO8124 yog ISO 8124-2: 2007, hloov kho xyoo 2007, uas qhia meej txog cov khoom siv hluav taws xob uas txwv tsis pub siv rau hauv cov khoom ua si thiab cov kev cai rau cov nplaim taws ntawm cov khoom ua si tshwj xeeb thaum raug hluav taws xob me me. Txoj Cai 5 ntawm ntu no teev cov txheej txheem xeem.

Ntu 3: Kev tsiv teb tsaws ntawm cov ntsiab lus tshwj xeeb
Qhov tseeb version ntawm qhov no ntawm ISO8124 yog ISO 8124-3: 2010, hloov kho rau lub Tsib Hlis 27, 2010. Qhov no tsuas yog tswj cov ntsiab lus hlau hnyav ntawm cov khoom siv hauv cov khoom ua si. Qhov hloov tshiab tsis hloov cov kev txwv tshwj xeeb ntawm tus qauv, tab sis ua rau cov kev hloov kho hauv qab no ntawm qee qib tsis yog txheej txheem:
1) Tus qauv tshiab qhia meej txog ntau yam ntawm cov khoom ua si uas yuav tsum tau sim, thiab nthuav dav ntau yam ntawm cov txheej txheej saum npoo tau sim raws li thawj tsab,
2) Tus qauv tshiab ntxiv cov ntsiab lus ntawm "daim ntawv thiab board",
3) Tus qauv tshiab tau hloov pauv qhov kev xeem reagent rau kev tshem tawm cov roj thiab siv quav ciab, thiab cov reagent hloov pauv tau ua raws li qhov tseeb ntawm EN71-3,
4) Tus qauv tshiab ntxiv tias qhov tsis paub meej yuav tsum tau txiav txim siab thaum txiav txim siab seb qhov kev tshuaj xyuas ntau npaum li cas,
5) Tus qauv tshiab tau hloov kho qhov siab tshaj qhov nqus tau ntawm antimony los ntawm 1.4 µg / hnub rau 0.2 µg / hnub.

Cov kev txwv tshwj xeeb rau ntu no yog raws li hauv qab no:
Nyob rau yav tom ntej, ISO 8124 yuav ntxiv ntau qhov chaw, raws li: tag nrho cov ntsiab lus tshwj xeeb hauv cov khoom ua si; Kev txiav txim siab ntawm phthalic acid plasticizers hauv cov ntaub ntawv yas, xws li

b

polyvinyl chloride (PVC).
