It applies to assemblies intended for distribution of electrical energy in systems (up to 1,000 V AC or 1,500 V DC). This includes: If you are searching for an , you

The standard mandates specific information to be provided by the manufacturer (e.g., rated voltage, IP rating) in the documentation. Summary of Verification Methods This public link is valid for 7 days

The standard describes verification of temperature‑rise for assemblies. This can be carried out by testing, but under defined boundary conditions, alternatives such as calculation (based on IEC TR 60890) are also permitted. For the verification of dielectric properties, the standard requires impulse voltage withstand verification, which is mandatory either by test or by design rules. The test is not required when clearances in the assembly are 1.5 times the specified value.
