Uhlolojikelele:

I-UL 2054 Ed.3 yakhululwa ngo-November 17, 2021. Njengelungu lezinga le-UL, i-MCM yabamba iqhaza ekubuyekezweni kwezinga, futhi yenza iziphakamiso ezinengqondo zokuguqulwa okwamukelwa kamuva.

Okuqukethwe Okubuyekeziwe:

Izinguquko ezenziwe kumazinga zihileleke kakhulu nezici ezinhlanu, ezibekwe kanjena:

• Ukwengezwa kwesigaba 6.3: Izidingo ezijwayelekile zokwakheka kwezintambo namatheminali:

l Intambo kufanele ivalwe, futhi kufanele ihlangabezane nezidingo ze-UL 758 kuyilapho kucatshangwa ukuthi izinga lokushisa elingaba khona kanye ne-voltage okutholwe kuyo ephaketheni lebhethri kwamukelekile.

l Amakhanda ezintambo namatheminali kufanele aqiniswe ngomshini, futhi kuxhunywe ugesi, futhi akumele kube nokushuba kwesimo ezintweni ezixhunywayo namatheminali.Umthofu kufanele uphephe, futhi ugcinwe kude nemiphetho ebukhali nezinye izingxenye ezingase zilimaze isivikeli sezintambo.

• Ukubuyekezwa Okuxubile kwenziwa kulo lonke Izinga;Izigaba 2 – 5, 6.1.2 – 6.1.4, 6.5.1, 8.1, 8.2, 11.10, 12.13, 13.3, 14.7, 15.2, 16.6, Isihloko seSigaba 23, 24.1, Isithasiselo A.
• Ukucaciswa kwezidingo zamalebula okunamathela;Isigaba 29, 30.1, 30.2
• Ukwengezwa kwezidingo nezindlela zokuhlolwa kokuqina kwe-Mark
• Ukuhlolwa Kwemithombo Yamandla Alinganiselwe kwaba yimfuneko yokuzikhethela;7.1
• Kucaciswe ukumelana kwangaphandle ekuhlolweni ngo-11.11.

Ukuhlolwa Kwesifunda Esifushane kwashiwo ukuthi kusetshenziswe intambo yethusi kuma-anode omfushane avumayo kanye nenegethivu esigabeni 9.11 sendinganiso yasekuqaleni, manje isibuyekezwe njengokuthi kusetshenziswa izinqamuleli zangaphandle ezingu-80±20mΩ.

Isaziso Esikhethekile:

Incazelo: T_ubuningi+T_amb+T_ma kuboniswe ngokungalungile esigabeni 16.8 no-17.8 sezinga, kuyilapho isisho esifanele kufanele sibe ngu-T_ubuningi+T_amb-T_ma,ebhekise ezingeni lokuqala.
