Good day to all,
Could you please clarify if IEC 61439 recognizes Aluminium as a conductor?
If yes then what are the temperature rise criteria limits defined for aluminium to aluminium joints?
Thanks!

The IEC61439-1; edition 3 was published in May 2020 which recognizes Aluminium as conductor with well defined temperature rise criteria limits - 55K for untreated Aluminium to Aluminium Joints
However there will be no significant impact on the existing solutions that are complying to earlier edition 2 except on the temperature rise criteria's for Aluminium conductor. A maximum temperature-rise of 55 K for bare (uncoated) Aluminium busbars and conductors (Al-Al joint) shall not exceed, to ensure safety & performance of the solution over a prolonged duration of service.
Also attaching excerpts of IEC 61439 Ed. 3, Table 6 - Temperature-rise limits (9.2) for your ready reference.
Thanks,
