Lokho i-NSF/ANSI 61 Ekuqinisekisa Ngempela
I-NSF/ANSI 61 icashunwa kumashidi edatha amaningi amathangi, kodwa ayiqondwa kahle kabanzi. Akusona isilinganiso samandla noma isiqinisekiso samanzi ahlanzekile.
I-NSF/ANSI 61 iqinisekisa ukuthi izinto ezithintana namanzi okuphuza azikhiphi ukungcola okungase kulimaze impilo yomuntu, ngaphezu kwemikhawulo echaziwe yokukhipha, ayiqinisekisi ukusebenza kwesakhiwo noma ikhono lokwelapha.
I-NSF/ANSI 61 (Izingxenye Zohlelo Lwamanzi Okuphuza, Imithelela Yezempilo) iyindinganiso Kazwelonke yaseMelika ehlola umthelela wezempilo wezinto ezithinta amanzi aphuzwayo, ngokukala ukungcola okungase kukhiphe ngaphansi kwezimo ezichaziwe.
Izici Eziyinhloko, Izingxenye Nezinhlobo
Ukugxila emthelelayezempilo: Kunciphisa ukufuduka kwezinsimbi, izinto eziphilayo nezinye izinto emanzini ngaphezu kwemingcele ephephile.
Ububanzi bezinto: Ama-coating, amathangi, amapayipi, izixhumi, nezingxenye ezimanzi konke kuqinisekiswa njengendlela yokwakheka.
Ukuhlolwa kokukhipha: Amasampula achayeka emanzini ngaphansi kwezimo ezimisiwe zokushisa nokuthintana; i-leachate iyalinganiswa.
Lokho okungeyona: Akusona isakhiwo, i-hydraulic noma indinganiso yokwelapha, futhi akusona ukugunyazwa okuphelele kwengxenye yonke yethangi.
Izicelo Nezimo Zokusetshenziswa
Kudingeka noma kubhekiselwa kuthangi lamanzi aphuzwayo, amapayipi nezingxenye ezimakethe eziningi (ikakhulukazi eNyakatho Melika), futhi kulindeleke kakhulu emishinini yamanzi okuphuza ethunyelwa kwamanye amazwe.
Ukucatshangelwa Kwezobuchwepheshe
Isitifiketi sisebenza ngokwakheka ngakunye nangengxenye ngayinye emanzi, ngakho uqweqwe lwe-enamel yethangi, noma yiluphi ulwelwesi, izivalo kanye nezinto zokuxhuma ngakunye kudinga isimo saso se-NSF/ANSI 61 ukuze isimangalo siphelele. Izinga lisebenzisa imikhawulo yokukhipha, hhayi ukuphasa/ukwehluleka 'kobumsulwa', futhi lisebenza emiphumeleni yezempilo yento, hhayi ekutheni ithangi liyamelana nokugqwala noma ligcina ingcindezi.
Ku-tanki eline-glass-lined, i-enamel formulation kanye nama-wetted seals yizinto ezibuyekezwayo. Abathengi kufanele bacele isitifiketi sangempela esisho i-formulation, hhayi isitatimende esijwayelekile, futhi bakhumbule ukuthi izinga likhuluma ngemiphumela yezempilo, hhayi impilo yesakhiwo.
Izinzuzo Nezithiyo
Izinzuzo:
Inikeza isisekelo esingachemi, somuntu wesithathu ukukhombisa ukuthi izinto ezithinta amanzi okuphuza ziphephile, kwenza kube lula ukuhambisana nokuthenga kumaphrojekthi amanzi okuphuza.
Izithiyo:
Akuhlanganisi ubuqotho besakhiwo, ukumelana nokugqwala noma ukusebenza kokwelapha, futhi isitifiketi sokwakheka okukodwa asihlanganisi ngokuzenzakalelayo okunye noma yonke inhlanganisela. Izinto ezilinganayo zesifunda (njenge-WRAS e-UK, i-ACS e-France) zingase zisebenze esikhundleni salokho.

Izinqubo Ezingcono Kakhulu Nendlela Yokukhetha
Cela isitifiketi sangempela esibiza ukwakheka okumanzi, qinisekisa ukuthi zonke izingxenye ezithinta amanzi aphuzwayo (okokumboza, izivalo, izinto zokuxhuma) zifakiwe, futhi hlanganisa i-NSF/ANSI 61 nezindinganiso zesakhiwo nokumboza okufanele zihlangatshezwe yithangi. Hlola okulingana kwesifunda lapho i-NSF ingeyona imfuneko yendawo.
I-NSF/ANSI 61 iqinisekisa ukuthi izinto ezithinta amanzi okuphuza azikhiphi ukungcola okuyingozi ngaphezu kwemikhawulo ebekiwe, akusona isiqinisekiso sesakhiwo noma sokusebenza. Cela isitifiketi esiqondene nokwakheka futhi usihlanganise nezinye izindinganiso ezidingekayo zethangi.
Imibuzo Evame Ukubuzwa (FAQ)
Yini i-NSF/ANSI 61 eyihlola ngempela?
Kukala ukungcola (izinsimbi, izinto eziphilayo) izinto ezingase zikhiphele emanzini okuphuza ngaphansi kwezimo ezichaziwe zokushisa nokuthintana, ngokuqhathaniswa nemikhawulo yokukhishwa esekelwe empilweni.
Ingabe i-NSF 61 iqinisekisa itanki lonke?
Cha. Iqinisekisa izinto ezimanzi kanye nama-formulation, njenge-coating, ama-seals kanye nama-fittings, ngazinye, hhayi isakhiwo setanki elihlanganisiwe noma ukusebenza kwalo.
Ingabe i-NSF 61 iyizinga lekhwalithi noma amandla?
Cha. Kuyindinganiso yemiphumela yezempilo kuphela yokuthintana namanzi aphuzwayo. Amandla esakhiwo, ukumelana nokugqwala kanye nekhono lokwelapha kuhlanganiswa kwezinye izindinganiso ngokuphelele.
Ngabe ngidinga i-NSF 61 ngaphandle kweNyakatho Melika?
Kudingeka kakhulu lapho, kodwa amaphrojekthi amaningi okuthumela ngaphandle ayilindele. Ezinye izimakethe zisebenzisa okufanayo njenge-WRAS (UK) noma i-ACS (France); hlola imfuneko yendawo.
Ngingasiqinisekisa kanjani isimangalo somhlinzeki se-NSF 61?
Cela isitifiketi esisho ukwakheka okuqondile okumanzi kanye nengxenye, futhi uqinisekise ukuthi ingxenye ngayinye ethinta amanzi okuphuza isohlwini, hhayi nje isitatimende esijwayelekile esithi 'kuqinisekiswe yi-NSF'.
