IEC 61641 applies to a wide range of enclosed electrical equipment, including:

This indicates that a new edition is expected in the near future, which may contain further significant technical changes or even a conversion from a Technical Report (TR) to a Technical Specification (TS). For anyone writing a long-term specification, it is worth keeping an eye on the development of this new edition.

While both address internal arcs, high-voltage standards (e.g., IEC 62271-200 for metal-enclosed switchgear) have different requirements and test methodologies. They often focus on different types of internal arc classifications (like IAC or A-FL) and are not directly interchangeable with IEC 61641, which is specifically tailored for low-voltage assemblies.
