Ipayipi eliyinhlanganisela yesampula yokulandelela ukushisa iyidivayisi ehambisa amasampula yokulandelela ukushisa ukuze kuqoqwe izinto ezisetshenziswayo epayipini. Ikakhulukazi yakhiwe ipayipi elingaphakathi kanye nepayipi elingaphandle. Ipayipi elingaphakathi lisetshenziselwa ukudlulisa izinto, kanti ipayipi langaphandle lisetshenziselwa ukushisa nokugcina ukushisa.

Izici ezibalulekile zeshubhu eliyinhlanganisela yokulandela umkhondo wokushisa zihlanganisa:

1, Ukulandelela ukushisa nokugcinwa kokushisa: ipayipi elingaphandle liyashisa futhi livale into engaphakathi kwepayipi ngokusebenzisa izinto zokushisisa ezifana netheyiphu yokushisisa kagesi, ukuze kuvinjwe okokusebenza ukuthi kuqiniswe noma kupholiswe phakathi nenqubo yokudlulisa.

2, Ukusampula nokuhlaziya: Kunembobo yesampula kushubhu yangaphakathi, engasampula futhi ihlaziye okokusebenza ukuze kulawulwe ikhwalithi nokucubungula amapharamitha wento.

3, Ukumelana nezinga lokushisa eliphezulu: Ipayipi eliyinhlanganisela yesampula yokufudumeza lingakwazi ukujwayela indawo yokushisa ephezulu futhi lilungele ukuqoqwa nokuthuthwa kwezinga lokushisa eliphezulu.

4, Ukumelana nokugqwala: Ipayipi eliyinhlanganisela yesampula yokushisisa lenziwe ngezinto ezimelana nokugqwala, ezikwazi ukujwayela ukuqoqwa nokuthuthwa kwezinto ezonakalisayo ezihlukahlukene.

Ngokujwayelekile, ishubhu eliyinhlanganisela yesampula yokulandelela ukushisa iyithuluzi lesampula lokulandelela ukushisa elisebenzayo, eliphephile futhi elihlala isikhathi eside, elisetshenziswa kakhulu embonini yamakhemikhali, i-petroleum, imithi, ukudla kanye neminye imikhakha.
