Environmental qauv
Raws li tib neeg txoj kev ua neej nyob txuas ntxiv txhim kho, cov kev xav tau ntawm cov khoom lag luam kuj tseem nce ntxiv. Ntau thiab ntau cov kev cai thiab cov qauv tshwm sim hauv txhua qhov chaw ntawm lub neej. Hauv kev lag luam tooj liab, muaj ntau yam qauv uas txwv cov khoom siv tooj liab.
1. EU cov qauv kev zam
Thaum Lub Ib Hlis 27, 2003, European Parliament thiab European Council tau tshaj tawm Cov Lus Qhia 2002/95/EC, uas yog "Kev txwv tsis pub siv qee yam khoom siv phom sij hauv hluav taws xob thiab hluav taws xob", hu ua RoHS Cov Lus Qhia. Cov ntsiab lus tseem ceeb yog: txij thaum Lub Xya Hli 1, 2006, kev siv rau 6 yam phom sij xws li txhuas, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) thiab polybrominated diphenyl ethers (PBDE) yuav raug txwv hauv cov khoom siv hluav taws xob tshiab thiab hluav taws xob. ntawm kev ua lag luam. Tom qab tso tawm RoHS cov lus qhia, nws tau dhau los ua txoj cai lij choj hauv EU txij lub Ob Hlis 13, 2003; ua ntej Lub Yim Hli 13, 2004, EU cov tswvcuab tau hloov dua siab tshiab rau lawv tus kheej txoj cai / kev cai; Lub Ob Hlis 13, 2005, European Commission tau tshuaj xyuas qhov kev qhia ntawm cov lus qhia thiab txiav txim siab txog kev tsim cov thev naus laus zis tshiab los tsim cov npe ntawm cov khoom txwv tsis pub ntxiv; Tom qab Lub Xya Hli 1, 2006, EU kev ua lag luam yuav raug txwv tsis pub muag cov khoom lag luam uas muaj cov ntsiab lus ntau dhau ntawm cov tshuaj no.
Cov kev txwv tshwj xeeb yog raws li nram no: Cadmium thiab nws cov tebchaw<100ppm Lead and its compounds <1000ppm Mercury and its compounds <1000ppm Hexavalent chromium compounds <1000ppm Polybrominated biphenyls (PBB) <1000ppm polybrominated diphenyl ether (PBDE) <1000ppm
Txawm li cas los xij, tooj liab alloy muaj kev zam hauv tus qauv no. Raws li Tshooj 6 (c) ntawm cov lus zam ntawm EU Cov Lus Qhia 2011/65 / EU, cov ntsiab lus ntawm tooj liab alloy yog<40000ppm, because lead brass needs to add lead to improve cutting performance, and the lead content is proportional to cutting performance before it does not exceed 3%.
2. Cov qauv kev tiv thaiv ib puag ncig
Vim qee qhov kev xav tau tshwj xeeb, qee qhov tooj dag yuav tsum tau nyob rau hauv kev sib cuag nrog tib neeg mus ntev lossis muaj cov txheej txheem tshwj xeeb
Cov neeg siv khoom yuav muaj cov kev cai tshwj xeeb rau cov ntsiab lus ntawm tooj dag Nws yuav tsum ua kom tau raws li EU ROSH tus qauv, uas yog qis dua 1000ppm hauv cov ntawv sau saum toj no.
Lub sijhawm no, lub npe ntawm tooj dag hloov pauv los ntawm cov hlau lead uas ua tau raws li EU tus qauv zam rau ib puag ncig tus phooj ywg (daj) tooj dag.
3. Sony tus qauv
Raws li qhov yuav tsum tau muaj ntawm SS00259, plaub tsab ntawm 2005 Sony technical standard, cov ntsiab lus ntawm cov khoom ua tiav semi-tiav, resistors thiab lwm yam khoom siv precision yuav tsum qis dua 100pmm. Lub sijhawm no, cov ntsiab lus txhuas feem ntau yog vim cov hlau lead seem uas tsis tau ntxuav los ntawm lub qhov cub. Lub sijhawm no, cov khoom siv tooj dag yuav tsis nquag ntxiv cov hmoov txhuas, tab sis siv qee cov khoom siv los hloov cov hmoov txhuas los txhim kho kev ua haujlwm ntawm kev txiav. Lub sijhawm no, cov tooj dag tuaj yeem hu ua tsis muaj txhuas thiab ib puag ncig zoo tooj liab.
