TPCH muri Amerika irekura umurongo ngenderwaho wa PFAS na Phthalates

Ugushyingo 2023, amabwiriza ya TPCH yo muri Amerika yasohoye inyandiko ngenderwaho kuri PFAS na Phthalates mubipakira. Iyi nyandiko ngenderwaho itanga ibyifuzo byuburyo bwo gupima imiti ijyanye no gupakira ibintu bifite uburozi.

Muri 2021, amabwiriza azaba arimo PFAS na Phthalates bigenzurwa kandi bibuza gukoresha nkana mugupakira no gutanga isoko. Hagati aho, buri gihugu cyahinduye amategeko ariho cyangwa gishyiraho amategeko n'amabwiriza mashya abuza ibintu bifite ubumara kandi byangiza mu gupakira. Vuba aha, leta nyinshi zabujije ikoreshwa rya PFAS mu gupakira ibiryo.
Iyi nyandiko iyobora itanga uburyo bwo gupima PFAS, nka fluoride yose. Niba ibirimo fluor byose biri munsi ya 100ppm kandi byujuje ubuziranenge bwo kugenzura ubuziranenge, ibicuruzwa birashobora gufatwa nkaho bidashoboka kongera nkana ibintu bya PFAS. Niba ibirimo fluor byose biri hasi cyane (nko munsi ya 100ppm), ibindi byemezo birashobora gukorwa hamwe nuwabitanze. Inyandiko ngenderwaho ishimangira ko gukorera mu mucyo ari ngombwa mu kubahiriza, kandi birasabwa gukoresha gahunda ikurikira kugira ngo hemezwe niba PFAS ishaka kongeraho:
1) Baza abatanga isoko kugirango bamenyekanishe ibintu byuzuye;
Saba abatanga isoko gutanga amakuru yuzuye;
2) Saba abatanga gufunga niba imiti ya PFAS yongeyeho;
Saba abatanga isoko kwerekana niba ibintu bya PFAS byongeweho;
3) Shakisha igice cya gatatu cyemeza ibikoresho byawe
Ushakisha ibyemezo byabandi.
TPCH itanga igitekerezo cyo gukoresha SW 846 uburyo 8270 mugutegura icyitegererezo hamwe nuburyo bwa EPA 3541 mugupakira ibikoresho bipima uburyo bwo gupima Phthalates. Ibikurikira nurutonde rwa phalite ikunze gusesengurwa nuburyo bwo gupima hejuru:

Laboratwari ya BTF ni ikigo cyipimisha cyemewe n’ikigo cy’igihugu cy’Ubushinwa gishinzwe kwemeza ibipimo ngenderwaho (CNAS), nimero: L17568. Nyuma yimyaka yiterambere, BTF ifite laboratoire ihuza amashanyarazi, laboratoire itumanaho idafite umugozi, laboratoire ya SAR, laboratoire yumutekano, laboratoire yizewe, laboratoire yo gupima batiri, gupima imiti nizindi laboratoire. Ifite amashanyarazi meza, guhuza radio, umutekano wibicuruzwa, kwizerwa kubidukikije, gusesengura ibintu, ROHS / REACH nubundi bushobozi bwo gupima. Laboratwari ya BTF ifite ibikoresho byumwuga kandi byuzuye, itsinda ryinzobere mu gupima no gutanga impamyabumenyi, hamwe nubushobozi bwo gukemura ibibazo bitandukanye byo gupima no gutanga ibyemezo. Twubahiriza amahame ngenderwaho y "" ubutabera, kutabogama, ubunyangamugayo, no gukomera "kandi dukurikiza byimazeyo ibisabwa na sisitemu yo gucunga laboratoire ya ISO / IEC 17025 na kalibrasi yo gucunga ubumenyi. Twiyemeje guha abakiriya serivisi nziza. Niba ufite ikibazo, nyamuneka twandikire igihe icyo aricyo cyose.
