PFHxA e tla kenyeletsoa taolong ea taolo ea REACH

Ka la 29 Hlakola, 2024, Komiti ea Europe ea Ngoliso, Tlhahlobo, Lilaesense le Thibelo ea Lik'hemik'hale (FINYELLANG) o khethile ho amohela tlhahiso ea ho thibela perfluorohexanoic acid (PFHxA), matsoai a eona, le lintho tse amanang le eona ho Appendix XVII ea molao oa REACH.
1. Mabapi le PFHxA, matsoai a eona, le lintho tse amanang le tsona
1.1 Boitsebiso ba lintho tse bonahalang
Perfluorohexanoic acid (PFHxA) le matsoai a eona le lintho tse amanang le eona li bua ka:
Metsoako e nang le lihlopha tsa perfluoroapentyl tse hokahantsoeng le liathomo tsa khabone tsa C5F11 tse otlolohileng kapa tse nang le makala.
Ho ba le lihlopha tse otlolohileng kapa tse nang le makala tsa C6F13 perfluorohexyl
1.2 Ho sa kenyeletsoe lintho tse latelang:
C6F14
C6F13-C (=O) OH, C6F13-C (=O) OX ′ kapa C6F13-CF2-X ′ (moo X ′=sehlopha sefe kapa sefe se sebetsang, ho kenyeletsoa letsoai)
Ntho efe kapa efe e nang le perfluoroalkyl C6F13- e hokahaneng ka kotloloho le liathomo tsa sebabole
1.3Litlhokahalo tse fokolang
Ka thepa e tšoanang:
PFHxA le kakaretso ea eona ea letsoai: ＜ 0.025 mg/kg
Kakaretso ea lintho tse amanang le PFHxA: ＜ 1 mg/kg
2. Sebaka sa ho laola
Lefulo la ho tima mollo le leholi la mollo le tsepamisitse maikutlo bakeng sa ntoa ea mollo ea sechaba, koetliso le liteko: likhoeli tse 18 kamora hore melaoana e kene tšebetsong.
Bakeng sa tšebeliso ea sechaba: masela, letlalo, boea, lieta, motsoako oa liaparo le lisebelisoa tse amanang le tsona; Litlolo; Pampiri ea ho ikopanya le lijo le khateboto: Likhoeli tse 24 ho tloha ka letsatsi la tšebetso la melaoana.
Masela, letlalo, le boea lihlahisoa tse ling ntle le liaparo le lisebelisoa tse amanang le tsona bakeng sa tšebeliso ea sechaba: Likhoeli tse 36 ho tloha ka letsatsi la ho qala ha melao.
Foam e loantšang mollo oa sefofane le foam ea ho loantša mollo e tsepamisitse maikutlo: likhoeli tse 60 ka mor'a hore melaoana e kene tšebetsong.
PFHxAs ke mofuta oa motsoako oa perfluorinated le polyfluoroalkyl (PFAS). Lintho tsa PFHxA li nkuoa li na le phehello le metsi. Li sebelisoa haholo liindastering tse ngata, tse kang pampiri le pampiri (lisebelisoa tsa ho ikopanya le lijo), masela a kang thepa ea ho itšireletsa, masela a ntlo le liaparo, le foam ea mollo. Leano la EU la nts'etsopele ea moshoelella bakeng sa lik'hemik'hale le beha leano la PFAS ka pele le setsing. Khomishene ea Europe e ikemiselitse ho felisa li-PFAS kaofela butle-butle le ho lumella ts'ebeliso ea tsona maemong ao ho netefalitsoeng hore e ke ke ea nkeloa sebaka ebile e le bohlokoa sechabeng.
BTF Test Lab e na le litsi tsa tlhahlobo tse hloahloa le tse felletseng, sehlopha se nang le boiphihlelo ba litsebi tsa tlhahlobo le setifikeiti, le bokhoni ba ho rarolla mathata a fapaneng a rarahaneng a liteko le a setifikeiti. Re latela melao-motheo e tataisang ea "ho hloka leeme, ho hloka leeme, ho nepahala le ho tiea" 'me re latela ka tieo litlhoko tsa tlhahlobo ea ISO/IEC 17025 tsamaiso ea taolo ea laboratori ea tlhahlobo bakeng sa tsamaiso ea mahlale. Re ikemiselitse ho fa bareki tšebeletso ea boleng bo holimo. Haeba u na le lipotso, ka kopo ikutloe u lokolohile ho ikopanya le rona ka nako efe kapa efe.
