The compulsory specification VC 9113 sets out detailed technical and administrative requirements for electric motors:
Scope of Coverage
The regulation applies to motors that:
- Have 2, 4, 6, or 8 poles. Acts
- Are rated for voltage above 50 V up to 1,000 V. Acts
- Have a power rating between 0.75 kW and 375 kW. Acts
- Include motors with non-standard flanges/shafts or geared variants. Acts
Exclusions
The specification does not cover:
- Single-speed motors with 10+ poles and multi-speed motors. Acts
- Motors with mechanical commutators (e.g., DC motors). Acts
- Motors fully integrated into machines. Acts

The intention behind these specific scope limitations is to focus regulatory effort on the most common and energy-impactful classes of electric motors used in industry and commercial applications.
