1.Umlinganiselo ogqwesileyo wokuphindaphinda kunye nomgca
2.Ukuthembeka okulungileyo kunye nokusebenza okuchasene nokuphazamiseka
3.Uxinzelelo oluhle lokutywina ukukwazi ukutywinwa
4.I-tube yokulinganisa ilahleko yoxinzelelo oluphantsi
5.Ubukrelekrele obuphezulu kunye noLondolozo lwasimahla
Imitha yokuqukuqela ye-Electromagnetic luhlobo lwemitha yesantya esinokuchaneka okuphezulu kunye nokuthembeka kwaye isetyenziswa ngokubanzi kwipetroleum, ubunjineli bemichiza, intsimbi, ukutya, umbane, iphepha, unyango lwamanzi, unikezelo lwamanzi, unikezelo lobushushu, ukhuseleko lokusingqongileyo kunye namanye amashishini.
Ukukhethwa kwemitha yombane yombane kufuneka kucace ngolu hlobo lulandelayo:
(1) Umlinganiselo ophakathi kufuneka ube lulwelo oluqhubayo, kuba igesi, i-oyile, izinyibilikisi zendalo kunye nezinye izinto ezingeyo-conductive azinakulinganiswa.
(2) Uluhlu lokulinganisa lwemitha yokuhamba yombane kufuneka lunikwe umenzi xa kuodolwa imodeli kunye neenkcukacha, kwaye umenzi kufuneka alinganise kolu luhlu lokulinganisa ukuqinisekisa ukuchaneka komlinganiselo wesixhobo.
(3) Umsebenzisi uya kubonelela ngeeparamitha kwitheyibhile yokukhetha, njengomlinganiselo ophakathi, iiparamitha zenkqubo, izinga lokuhamba kunye nobushushu bokusebenza kunye noxinzelelo, kumenzi, kwaye ukhethe imitha yokuhamba efanelekileyo ngokwezi parameters.
(4) Ukhetho lohlobo olukhethekileyo lokuhamba kwexesha lokuhamba kwe-electromagnetic, umsebenzisi ngokwendawo yokufaka isiguquli kumgama woluvo, abeke phambili ubude beemfuno zocingo kumzi-mveliso.
(5) Ukuba umsebenzisi kufuneka afake izincedisi, ezifana ne-flange exhasayo, i-pad ring pad, iibholiti, amantongomane, i-washers kunye nezinye iimfuno ezongezelelweyo, zinokubekwa phambili xa zi-odola.
