Within the deep text of IEC 60439-1 (specifically regarding construction), the standard defined "Forms of Internal Separation." This is a granular feature often referenced by switchgear engineers:
The original standard focused on defining the technical parameters, environmental limits, construction rules, and testing parameters for electrical distribution panels, motor control centers (MCCs), and main switchboards. IEC 60439-1:1999
The defining characteristic of the IEC 60439-1 standard was its binary categorization of manufacturing compliance:
