There are of course the existing IEC (or UL / Nema) standards for LV or MV switchgear assemblies, which end-users should ask as a minimum requirement in my opinion, to ensure a good level of safety of people, reliability of the switchboard along its life duration ... but not all end-users require this minimum compliance today, as far as I know, it depends a lot on country and application you are talking about. Just as an example, for LV switchboard you can refer to the IEC60439-1, which is in the process of being replaced by the new IEC61439-2 (see this link to know more). For medium voltage switchboards, you can refer to IEC 62271-2xx standards (HV assemblies) Generally speaking, these acceptance criteria / tests should be listed by the end-user or designer in their specification file.
