Amapayipi e-polyethylene asesetshenziswe amakhasimende ethu ekunikezeni amanzi okuphuza kusukela asungulwa ngawo-1950.Imboni yepulasitiki ithathe umthwalo omkhulu wokuqinisekisa ukuthi imikhiqizo esetshenziswayo ayilithinti kabi izinga lamanzi.

Uhlu lokuhlola olwenziwa kumapayipi e-PE ngokuvamile luhlanganisa ukunambitheka, iphunga, ukubukeka kwamanzi, nokuhlolwa kokukhula kwezilwanyana ezincane zasemanzini.Lolu wuhlu olubanzi kakhulu lokuhlola olusetshenziswa njengamanje ezintweni zamapayipi esintu, njengezinsimbi nosimende nemikhiqizo efakwe usimende, emazweni amaningi ase-Europe.Ngakho-ke kukhona ukuqiniseka okukhulu kokuthi ipayipi le-PE lingasetshenziselwa ukuhlinzekwa kwamanzi aphuzekayo ngaphansi kwezimo eziningi zokusebenza.

Kunokwehluka okuthile kumithetho kazwelonke enjalo nezindlela zokuhlola ezisetshenziswa phakathi kwamazwe aseYurophu.Imvume yokufaka isicelo samanzi aphuzwayo inikeziwe kuwo wonke amazwe.Ukugunyazwa kwemizimba elandelayo kuyabonwa kwamanye amazwe aseYurophu futhi ngezinye izikhathi nasemhlabeni jikelele:

I-UK Drinking Water Inspectorate (DWI)

I-Germany Deutsche Verein des Gas-und Wasserfaches (DVGW)

Inkampani Netherlands KIWA NV

France CRECEP Centre de Recherche, d'Expertise et de

I-Contrôle des Eaux de Paris

Izinhlanganisela zamapayipi e-PE100 kufanele zenziwe ukuze zisetshenziswe ekufakweni kwamanzi aphuzekayo.Ngaphezu kwalokho ipayipi le-PE100 lingakhiqizwa kusukela kunhlanganisela eluhlaza okwesibhakabhaka noma emnyama enemigqa eluhlaza okwesibhakabhaka ekhomba ukuthi ifanele ukusetshenziswa ezindaweni zokugezela zamanzi.

Olunye ulwazi mayelana nokugunyazwa ukusetshenziswa kwamanzi aphuzwayo lungatholakala kumkhiqizi wamapayipi uma kudingeka.

Ukuze kuhambisane nemithethonqubo kanye nokuqinisekisa ukuthi zonke izinto ezisetshenziswa lapho kuthintana namanzi okuphuza ziphathwa ngendlela efanayo, i-EAS European Approval Scheme iyathuthukiswa, ngokusekelwe kuKhomishini YaseYurophu.

I-Directive 98/83/EC.Lokhu kwenganyelwe yiqembu labaLawuli baManzi baseYurophu, i-RG-CPDW - Iqembu Labalawuli Bemikhiqizo Yokwakha Ngokuthintana Namanzi Okuphuza.Kuhloswe ukuthi i-EAS iqale ukusebenza ngo-2006 ngefomu elilinganiselwe, kodwa kubonakala kungenakwenzeka ukuthi isetshenziswe ngokugcwele kuze kube idethi yakamuva kakhulu lapho izindlela zokuhlola sezisetshenziswa kuzo zonke izinto zokusebenza.

Amapayipi epulasitiki amanzi okuphuza ahlolwe ngokuqinile yiZwe ngalinye eliyiLungu le-EU.Inhlangano yabahlinzeki bezinto zokusetshenziswa (iPlastiki Europe) sekunesikhathi eside ikhuthaza ukuthi kusetshenziswe amapulasitiki okuxhumana nokudla uma kufakwe isicelo samanzi okuphuza, ngoba imithetho yokuxhumana nokudla iqinile kakhulu ekuvikeleni impilo yabathengi nokusebenzisa ukuhlolwa kobuthi njengoba kudingwa kumhlahlandlela weKomidi Lesayensi Yekhomishini YaseYurophu. for Food (enye yamakomiti e-EU Food Standards Agency).I-Denmark, isibonelo, isebenzisa umthetho wokuxhumana nokudla futhi isebenzisa indlela yokuphepha eyengeziwe.Izinga lamanzi okuphuza laseDenmark lingelinye elinzima kakhulu eYurophu.
