I-TPCH eUnited States ikhupha izikhokelo zePFAS kunye nePhthalates

NgoNovemba ka-2023, umgaqo we-TPCH wase-US ukhuphe uxwebhu lwesikhokelo kwi-PFAS kunye ne-Phthalates kwi-package. Olu xwebhu lwesikhokelo lubonelela ngeengcebiso malunga neendlela zokuvavanya iikhemikhali ezithobela ukupakishwa kwezinto eziyityhefu.

Ngo-2021, imimiselo iya kubandakanya i-PFAS kunye ne-Phthalates phantsi kolawulo kwaye ithintele ukusetyenziswa kwabo ngabom ekupakisheni kunye nokubonelela kwayo. Okwangoku, urhulumente ngamnye wenze uhlengahlengiso kwimithetho ekhoyo okanye wenze imithetho emitsha kunye nemimiselo yokuthintela izinto ezinobuthi kunye neziyingozi ekupakisheni. Kutshanje, amazwe amaninzi akuthintele ukusetyenziswa kwezinto ze-PFAS kwipakethe yokutya.
Olu xwebhu lwesikhokelo lubonelela ngeendlela zovavanyo ezicetyiswayo zePFAS, ezinje ngefluoride iyonke. Ukuba umxholo opheleleyo we-fluorine ungaphantsi kwe-100ppm kwaye udibana nemigangatho yolawulo lomgangatho, imveliso inokuqwalaselwa njengento enokuthi ingongezi ngabom izinto zePFAS. Ukuba umxholo wefluorine uwonke uphantsi kakhulu (ofana nongaphantsi kwe-100ppm), uqinisekiso olongezelelweyo lunokwenziwa kunye nomthengisi. Uxwebhu olusisikhokelo lugxininisa ukuba ukubeka elubala kubalulekile ekuthotyelweni, kwaye kuyacetyiswa ukuba kusetyenziswe esi sicwangciso silandelayo ukuqinisekisa ukuba iPFAS ijonge ukongeza:
1) Cela ababoneleli ngenkcazelo epheleleyo ngezinto eziphathekayo;
Funa ababoneleli ukuba babonelele ngokubhengezwa kwemathiriyeli ebanzi;
2) Cela ababoneleli ukuba bavale ukuba iikhemikhali zePFAS zongezwa;
Funa ababoneleli ukuba bachaze ukuba ingaba izinto zePFAS zongeziwe na;
3) Khangela isiqinisekiso somntu wesithathu kwizinto zakho
Ukukhangela isatifikethi somntu wesithathu.
I-TPCH icebisa ukusebenzisa i-SW 846 indlela ye-8270 yokulungiswa kwesampulu kunye ne-EPA indlela ye-3541 yokupakisha uvavanyo lwemathiriyeli malunga nendlela yokuvavanya i-Phthalates. Olu lulandelayo luluhlu lwe-phthalates oludla ngokuhlalutywa ngezi ndlela zovavanyo zingentla:

ILebhu yoVavanyo lwe-BTF liziko lovavanyo elivunyiweyo yiNkonzo yeSizwe yoQinisekiso lwaseTshayina yoVavanyo lokuThobela (CNAS), inombolo: L17568. Emva kweminyaka yophuhliso, i-BTF inelabhoratri ehambelana ne-electromagnetic, ilabhu yonxibelelwano engenazingcingo, ilebhu yeSAR, ilebhu yokhuseleko, ilebhu yokuthembeka, ilebhu yovavanyo lwebhetri, uvavanyo lwekhemikhali kunye nezinye iilabhoratri. Inonxibelelwano olugqibeleleyo lwe-electromagnetic, amaza onomathotholo, ukhuseleko lwemveliso, ukuthembeka kokusingqongileyo, uhlalutyo lokusilela kwezinto, i-ROHS/REACH kunye nobunye ubuchule bokuvavanya. ILebhu yoVavanyo lwe-BTF ixhotyiswe ngamaziko ovavanyo abuchwephesha kunye apheleleyo, iqela elinamava ovavanyo kunye neengcali zesatifikethi, kunye nokukwazi ukusombulula uvavanyo oluntsonkothileyo kunye neengxaki zesiqinisekiso. Sithobela imigaqo ekhokelayo "yobulungisa, ukungakhethi buso, ukuchaneka, kunye nokungqongqo" kwaye silandela ngokungqongqo iimfuno ze-ISO/IEC 17025 yovavanyo kunye nenkqubo yolawulo lwelebhu yokulinganisa kulawulo lwezenzululwazi. Sizimisele ukubonelela abathengi ngeyona nkonzo iphakamileyo. Ukuba unayo nayiphi na imibuzo, nceda uzive ukhululekile ukuqhagamshelana nathi nangaliphi na ixesha.
