Ifomu loku-oda kumele lifake izinto ezingu-11 ezilandelayo:
1. Ubuningi (izinyawo, amamitha noma inani lezinduku)
2. Igama lezinto (ipayipi eliyi-alloy yensimbi engenamthungo)
3. Amazinga (angu-16 esewonke: P1, P2, P22, P11, P22, P91)
4. Indlela yokukhiqiza (ukuqeda okushisayo noma ukudweba okubandayo)
5. Sebenzisa enye yalezi zincazelo ezilandelayo: 1), inombolo yochungechunge yobukhulu bodonga lwe-NPS kanye nepayipi, 2), ububanzi bangaphandle kanye nobukhulu bodonga obujwayelekile, 3), ububanzi bangaphandle kanye nobukhulu bodonga obuncane, 4), ububanzi bangaphakathi kanye nobukhulu bodonga obujwayelekile, 5), imiyalelo yoku-oda ububanzi bangaphakathi kanye nobukhulu bodonga obuncane
6. Ubude (buhlukaniswe ngobude obungaguquki kanye nobude obunganqunyelwe)
7. Qeda ukucubungula.
8. Izidingo zokukhetha (umfutho wamanzi kanye nokuphambuka kwesisindo okuvumelekile).
9. Imibiko yokuhlola edingekayo (bheka i-A530).
10. Inombolo ejwayelekile. 11 Izidingo ezikhethekile noma yiziphi izidingo ezengeziwe zokuzikhethela.
Izinto zokwakha kanye nokukhiqiza
1. Amapayipi ensimbi ajwayelekile angaqedwa ngokushisa noma ngokudonswa kubanda, futhi adlule ekushiseni kokugcina okudingekayo ngokwezinga elijwayelekile.
2. Insimbi yezinga le-P2 ne-P12. Lawa mazinga amabili ensimbi kufanele akhiqizwe kusetshenziswa inqubo yokuncibilikisa okusanhlamvu okuqinile. Uma kunezidingo ezikhethekile zobukhulu bokusanhlamvu noma inqubo yokususa i-oxidation, kufanele kuvunyelwane ngazo ngumthengi kanye nomenzi wensimbi.
3. Ukwelashwa ngokushisa
1. Ngaphandle kwensimbi ye-PSC, P23, P91, P92, P122 kanye ne-P911 futhi njengoba kuchaziwe, wonke amazinga amapayipi ajwayelekile kufanele aphinde afudunyezwe futhi anikezwe esimweni esifakwe ngokuphelele, esifakwe isothermal noma esilinganiselwe nesilinganiselwe. Uma enikezwa esimweni esilinganiselwe nesilinganiselwe, izinga lokushisa eliphansi lokushisa lensimbi ye-P5, P5B, P9, P21 kanye ne-P22 kufanele libe ngu-675°C. Izinga lokushisa eliphansi lokushisa lensimbi ye-P1, P2, P11, P12 kanye ne-P15 kufanele libe ngu-650 ℃
2. Ukwelashwa kokugcina kokushisa kwensimbi ye-P92 kanye ne-P911 kufanele kube okujwayelekile okungenani okungu-1040 ℃ kanye nokushisa okungenani okungu-730 ℃.
