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 kucutshungulwa 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.
