Safety of transformers, reactors, power supply units and combinations thereof - Particular requirements and tests for constant voltage transformers and power supply units for constant voltage1 Scope Replacement: This part of IEC 61558 deals with the safety of constant voltage transformers for general applications and power supply units for constant voltage for general applications. Constant voltage transformers incorporating electronic circuits are also covered by this standard. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here onward, the term transformer covers constant voltage

It assists the fire engineering community in formulating fire-fighting strategies for the protection of buildings and complements the guidance provided in BS 5306-0 Fire protection installations and equipment on premises
