Isishwankathelo:

I-UL 2054 Ed.3 yakhutshwa ngoNovemba 17, 2021. Njengelungu lomgangatho we-UL, i-MCM ithathe inxaxheba ekuhlaziyweni komgangatho, kwaye yenza iingcebiso ezifanelekileyo zokuguqulwa okwamkelwa emva koko.

Isiqulatho esiHlaziyiweyo:

Utshintsho olwenziweyo kwimigangatho lubandakanyeka ikakhulu kwimiba emihlanu, ecaciswa ngolu hlobo lulandelayo:

• Ukongezwa kwecandelo 6.3: Iimfuno ngokubanzi zokwakhiwa kweengcingo kunye neetheminali:

l Ucingo kufuneka lufakwe i-insulation, kwaye kufuneka luhlangabezane neemfuno ze-UL 758 ngelixa uqwalasela ukuba ubushushu obunokwenzeka kunye nombane odibana nawo kwipakethi yebhetri yamkelekile.

l Iintloko zocingo kunye neetheminali kufuneka ziqiniswe ngoomatshini, kwaye uqhagamshelwano lombane kufuneka lubonelelwe, kwaye kungabikho xinzelelo kwiitheminali kunye neetheminali.Ilothe kufuneka ikhuseleke, kwaye igcinwe kude kwincam ezibukhali kunye nezinye iindawo ezinokuthi zonakalise isigqubuthelo socingo.

• Uhlaziyo olwahlukeneyo lwenziwa kuMgangatho wonke;Amacandelo 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, Icandelo 23 isihloko, 24.1, Isihlomelo A.
• Ukucaciswa kweemfuno zeelebhile zokunamathela;Icandelo 29, 30.1, 30.2
• Ukongezwa kweemfuno kunye neendlela zoVavanyo lokuQiniseka kweMakisha
• UVavanyo lweMthombo waMandla oMnyiniweyo lube yimfuneko yokuzikhethela;7.1
• Ukucacisa ukuchasana kwangaphandle kuvavanyo kwi-11.11.

UVavanyo lweSekethe eMfutshane lwamiselwa ukuba lusebenzise ucingo lwekopolo kwisekethe emfutshane ye-anode elungileyo kunye nengalunganga kwicandelo le-9.11 lomgangatho wokuqala, ngoku luhlaziywe kusetyenziswa i-80±20mΩ izixhasi zangaphandle.

Isaziso esiKhethekileyo:

Inkcazo: T_max+T_amb+T_ma kuboniswe gwenxa kwicandelo 16.8 kunye ne-17.8 lomgangatho, ngelixa intetho echanekileyo kufuneka ibe ngu-T._max+T_amb-T_ma,ibhekisa kumgangatho wokuqala.
