Indlela Yokuqinisekisa Ukuthi Amathangi Amanzi Ahambisana ne-NSF/ANSI 61: Umhlahlandlela Wokuphumelela
Ukuqinisekisa ukuthi ithangi lakho lamanzi lihambisana ne-NSF/ANSI 61 akuyona nje into yokubeka ibhokisi; kuyisidingo esibalulekile sempilo yomphakathi. Ngoba i-NSF/ANSI 61 yindinganiso yohlelo lonke, ukuqinisekisa ukuhambisana kwamaphaneli ensimbi wedwa akwanele. Ukuze uqinisekise ukuthi ithangi lakho lihlangabezana nenqanaba, kufanele usebenzise isu le-"System-Wide Compliance" elihlanganisa isikhumba, izinto zokubopha, izimpawu, kanye nezinsimbi zangaphakathi.
1. Yamukela Indlela Yokuqinisekisa "Yohlelo Lonke"
Ukwehluleka kokuhambisana okuvame kakhulu kwenzeka lapho onjiniyela bekhetha "ithangi eliqinisekisiwe" kodwa basebenzise izingxenye ezingezona eziqinisekisiwe. I-NSF/ANSI 61 isebenza kuzo zonke izinto ezithinta amanzi.
Lapho ukhetha noma uthenga ithangi lakho, kufanele uqinisekise ukuthi izinto ezilandelayo ziqinisekisiwe ngazinye:
● Izinto Zokuvikela: Ukugqoka kwangaphakathi (i-Glass-Fused-to-Steel, i-Fusion-Bonded Epoxy, noma i-Stainless Steel) kufanele kuqinisekiswe ngaphansi kwesigaba "se-Barrier Materials" sendinganiso.
● Izimpawu Zokubopha Nezikhwebu: Lezi yizindawo eziyinhloko zokuhluleka. Qinisekisa ukuthi izikhwebu zenjoloba noma ze-elastomer ezisetshenziselwa ukuvala izimbobo zamaphaneli ziqinisekisiwe yi-NSF 61.
● Izikulufo/Iziciko Zama-bolt: Uma kusetshenziswa ama-bolt angaphakathi, qinisekisa ukuthi enziwe ngezinto eziqinisekisiwe noma ambozwe ngeziciko zepulasitiki eziqinisekisiwe yi-NSF ukuze kuvinjelwe ukugqwala nokuvuza endaweni yokuxhuma.
2. Inqubo Yokuthenga Yokuhambisana Izinyathelo Ezi-4
Ukuqinisekisa ukuthi iphrojekthi yakho ihlala ihambisana kusukela kumdwebo wokwakha kuze kube ukuhlolwa kokugcina, landela le nqubo eqinile:
Isinyathelo 1: Ukucaciswa Kokuphathwa
Esicelweni Sakho Sokunikezwa (RFP), gcizelela ngokuthi: "Uhlelo lonke lokugcina, okubandakanya amapheneli, izimpawu, izinto zokubopha, nezikulufu, kumelwe kufakazelwe ku-NSF/ANSI 61, Isigaba 5 (Izinto Zokuvimbela)." Ungamukeli ulimi oluthi "luhambisana" noma "lufanele"—funa Isitifiketi Sokufakwa ohlwini.
Isinyathelo 2: Ukuqinisekiswa Kokufakwa ohlwini
Ungathembeli ezitatimendeni zomkhiqizi. Sesha isizindalwazi sezimikhiqizo ze-NSF International ukuze uqinisekise ukufakwa ohlwini komkhiqizi.
● Isenzo: Hlola ukuthi imodeli yomkhiqizo ethile kanye nokusetshenziswa okuhlosiwe (amanzi okuphuza) kusebenza.
● Hlola: Qinisekisa ukuthi usuku lokuphelelwa yisikhathi kohlu lusesikhathini.
Isinyathelo 3: Ukuqinisekiswa Kokufakwa
Umkhiqizo ohambisanayo ungaba ongahambisanayo ngenxa yokufakwa okungalungile.
● Abafaki Abagunyaziwe: Sebenzisa osonkontileka abaqeqeshwe umenzi we-tank ngqo.
● Gwema Ukufaka Okunye: Qinisekisa ukuthi umfaki akashintshi izinto zokubopha noma uwoyela ongagunyaziwe ezivela eceleni ngesikhathi sokwakhiwa.
Isinyathelo 4: Inhlanzeko Nokugcinwa (ITM)
Ukuhambisana ne-NSF/ANSI 61 kuyimfuneko "yokuhamba kwesikhathi". Uma ingaphandle langaphakathi lonakaliswa ukuhlanza okungalungile, ikhwalithi yamanzi ingase yehle. Landela izindinganiso ze-AWWA (American Water Works Association) zokuhlanza nokubulala amagciwane, uqinisekise ukuthi izinto zokubulala amagciwane ezine-NSF certified kuphela ezisetshenziswa ekuhlanzweni.
3. Ukuqhathanisa: Indlela Eqinisekisiwe vs. Engaqinisekisiwe
Isigaba Sokuhambisana | Ukuhambisana Kwesistimu Yonke (Kunconyiwe) | Indlela Yengxenye-Yengxenye (Ingozi Ephakeme) |
Procurement | Dingeka "Isitifiketi Sokufakwa ohlwini" kuzo zonke izingxenye. | Cabanga ukuthi "Ithangi Elifakazelwe yi-NSF" yanele. |
Ukuqinisekiswa Kwezinto | Hlola isizindalwazi samagobolondo, izimpawu, nezikulufu. | Hlola kuphela impahla eyinhloko yepheneli. |
Ukufakwa | Izinhlelo ezigunyazwe umkhiqizi, ezivalwe ngesitifiketi. | Ukuguqulwa endaweni ngezinto zokubopha ezingafakazelwanga. |
Isimo Esisemthethweni | Ilungele ukuhlolwa; ihambisana namakhodi endawo. | Ingozi yomthwalo; ukuvalwa kohlelo okungenzeka. |
4. Imibuzo Evame Ukubuzwa (FAQ)
Umbuzo: Uma amaphaneli ami anesitifiketi se-NSF 61, ingabe ithangi lonke liyadlula?
A: Cha. Uma izikhwebu ezisetshenziswa phakathi kwamaphaneli zingaqinisekisiwe, uhlelo lonke luzohluleka ukuhlolwa. Njalo qinisekisa isitifiketi sezinto ezakhiwe (izimpawu, ama-bolt, izikhwebu).
Q: Ngingasebenzisa amathangi amanzi e-NSF 61 ukuze Kuvikelwe Umlilo?
A: Ngokuvamile, cha. Amathangi okuvikela umlilo alawulwa yi-NFPA 22. Noma ithangi lomlilo lingaba ne-NSF 61 certified, ithangi elenzelwe ukuvikela umlilo kuphela lihlale lisebenzisa izinto zangaphakathi ezingafakazelwanga ezifanele amanzi okuphuza. Ungalokothi uhlanganise lezi zinhlelo ngaphandle kokuqinisekisa isimo esiqondile sezinto ezisetshenzisiwe.
Umbuzo: Ngingaludinga ukuphinda ngiqinisekise ukuhambisana kangaki?
A: Awudingi ukuphinda uqinisekise umklamo wethangi uma usufakiwe, inqobo nje uma ungawenzisi izinguquko. Kodwa-ke, uma wenza ukulungiswa okubandakanya izinto ezintsha zokubopha, izendlalelo, noma amaphaneli, lezo zinto ezintsha ezithile kufanele zihambisane ne-NSF 61.
Isiphetho
Ukuqinisekisa ukuthi ithangi lakho lamanzi lihambisana ne-NSF/ANSI 61 kuphathelene nemibhalo enemininingwane kanye nokuqondisa okuhlelekile. Ngokuhoxa ekuqinisekisweni kwe-"ingxenye eyodwa" nokwamukela Ukuhambisana Kwesistimu Yonke, ususa isikweletu futhi uqinisekisa ukuphepha kwesikhathi eside kokuhlinzekwa kwamanzi okuphuzwayo esikhungweni sakho.
Ngabe njengamanje uphatha iphrojekthi yokuthenga uhlelo olusha lokugcina amanzi, noma ngabe uhlola ithangi elikhona? Ukwazi isigaba sakho samanje kungangisiza nginikeze ulimi oluqondile lwemibhalo lwe-RFP yakho.
