BSI has just published a new revision to a major IT equipment safety standard.


BS EN 60950-1:2006 Information technology equipment. Safety. General requirements applies to mains-powered or battery-powered information technology equipment, including electrical business equipment and associated equipment, with a rated voltage not exceeding 600 V. 

It applies to information technology equipment:

  • Designed to use the AC mains supply as a communication transmission medium.
    In addition, this standard applies to components and subassemblies intended for incorporation in information technology equipment.

BS EN 60950-1:2006 specifies requirements intended to reduce risks of fire, electric shock or injury for the operator and layman who may come into contact with the equipment and, where specifically stated, for a service person. It is intended to reduce such risks with respect to installed equipment, whether it consists of a system of interconnected units or independent units, subject to installing, operating and maintaining the equipment in the manner prescribed by the manufacturer.
