TPCH muUnited States inoburitsa nhungamiro yePFAS nePhthalates

MunaNovember 2023, mutemo weUS TPCH wakabudisa gwaro rekutungamira paPFAS nePhthalates mukurongedza. Gwaro iri regwaro rinopa kurudziro panzira dzekuyedza makemikari anoenderana nekurongedza zvinhu zvine chepfu.

Muna 2021, mirau ichasanganisira PFAS nePhthalates iri pasi pehutongi uye inorambidza kushandiswa kwavo nemaune mukurongedza uye neketani yekugovera. Zvichakadaro, nyika imwe neimwe yakaita zvigadziriso kumitemo iripo kana kudzika mitemo mitsva nemirau yekurambidza zvinhu zvine chepfu uye zvinokuvadza mukurongedza. Munguva pfupi yapfuura, nyika zhinji dzakarambidza kushandiswa kwezvinhu zvePFAS mukurongedza chikafu.
Gwaro iri regwaro rinopa nzira dzekuyedza dzinokurudzirwa dzePFAS, senge yakazara fluoride. Kana iyo yakazara fluorine yemukati iri pazasi 100ppm uye inosangana nemhando yekudzora zviyero, chigadzirwa chinogona kutariswa sechingangove chisiri nemaune kuwedzera PFAS zvinhu. Kana iyo yakazara fluorine yemukati yakadzikira (senge pazasi 100ppm), imwe simbiso inogona kuitwa nemutengesi. Gwaro rekutungamira rinosimbisa kuti kubuda pachena kwakakosha pakuteerana, uye zvinokurudzirwa kushandisa chirongwa chinotevera kuratidza kana PFAS ichida kuwedzera:
1) Bvunza vatengesi kuti vaburitse zvizere zvinhu;
Inoda kuti vatengesi vape ruzivo rwakakwana rwezvinhu;
2) Bvunza vatengesi kuti vavhare kana PFAS makemikari akawedzerwa;
Inoda kuti vatengesi vataure kana zvinhu zvePFAS zvawedzerwa;
3) Tsvaga yechitatu bato certification yezvinhu zvako
Kutsvaga wechitatu-bato certification.
TPCH inopa zano rekushandisa SW 846 nzira 8270 yemuenzaniso kugadzirira uye EPA nzira 3541 yekurongedza zvinhu kuyedza nezve nzira yekuyedza yePhthalates. Inotevera rondedzero yemaphthalates anowanzo kuongororwa nepamusoro nzira dzekuyedza:

BTF Testing Lab inzvimbo yekuyedza yakatenderwa neChina National Accreditation Service yeConformity Assessment (CNAS), nhamba: L17568. Mushure memakore ebudiriro, BTF ine electromagnetic inoenderana murabhoritari, isina waya yekutaurirana murabhoritari, SAR rabhoritari, kuchengetedza marabhoritari, kuvimbika marabhoritari, marabhoritari yekuyedza bhatiri, kuongororwa kwemakemikari uye mamwe marabhoritari. Iine yakakwana electromagnetic inoenderana, redhiyo frequency, kuchengetedzwa kwechigadzirwa, kuvimbika kwezvakatipoteredza, kuongororwa kutadza kwezvinhu, ROHS / REACH uye humwe hunyanzvi hwekuyedza. BTF Testing Lab yakashongedzerwa nehunyanzvi uye yakakwana yekuyedza zvivakwa, timu ine ruzivo yekuyedza uye nyanzvi dzezvitupa, uye kugona kugadzirisa kwakasiyana kwakaoma kuyedzwa uye matambudziko etifiketi. Isu tinoomerera kune inotungamira misimboti ye "kurongeka, kusarerekera, kurongeka, uye kuomarara" uye tinonyatso kutevedzera zvinodiwa ne ISO/IEC 17025 yekuyedza uye calibration laboratory manejimendi system yekutonga kwesainzi. Takazvipira kupa vatengi basa remhando yepamusoro. Kana uine mibvunzo, ndapota inzwa wakasununguka kutibata nesu chero nguva.
