UL 2054 Ed.3 idatulutsidwa pa Novembara 17, 2021. Monga membala wa muyezo wa UL, MCM idatenga nawo gawo pakuwunikanso mulingowo, ndipo idapereka malingaliro omveka pakusintha komwe kudakhazikitsidwa pambuyo pake.

Zomwe Zasinthidwa:

Zosintha zomwe zidapangidwa pamiyezo zimakhudzidwa makamaka ndi zinthu zisanu, zomwe zimafotokozedwa motere:

• Kuonjezera ndime 6.3: Zofunikira zonse pamapangidwe a mawaya ndi ma terminals:

l Waya uyenera kukhala wotsekereza, ndipo uyenera kukwaniritsa zofunikira za UL 758 poganizira ngati kutentha komwe kungachitike ndi magetsi omwe amapezeka mu batire paketi ndizovomerezeka.

l Mawaya a mitu ndi matheminali azilimbikitsidwa mwamakina, ndipo kulumikizidwa kwamagetsi kuyenera kuperekedwa, ndipo pasakhale zovuta zolumikizirana ndi ma terminals. Mtsogoleriyo uyenera kukhala wotetezeka, ndipo ukhale kutali ndi m'mbali zakuthwa ndi mbali zina zomwe zingawononge makina oteteza waya.

• Zosintha zosiyanasiyana zimapangidwa mu Standard Standard; Ndime 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, Gawo 23 mutu, 24.1, Zowonjezera A.
• Kufotokozera zofunikira za zolemba zomatira; Ndime 29, 30.1, 30.2
• kuwonjezera zofunika ndi njira za Mark Durability Test
• Made Limited Power Source Test kukhala chofunikira; 7.1
• Anafotokozera kukana kwakunja mu mayeso mu 11.11.

Mayeso a Short Circuit adanenedwa kuti agwiritse ntchito waya wamkuwa kupita kufupi ndi ma anode abwino komanso oyipa pa gawo 9.11 la muyezo woyambirira, tsopano adasinthidwanso ngati kugwiritsa ntchito 80 ± 20mΩ zopinga zakunja.

Chidziwitso Chapadera:

Mawu akuti: T_max+T_amb+T_ma adawonetsedwa molakwika mu gawo 16.8 ndi 17.8 la muyezo, pomwe mawu olondola ayenera kukhala T._max+T_amb-T_ma,ponena za muyezo woyambirira.
