BSI has published BS EN 60950-1:2006+Amendment 1:2010, Information technology equipment. Safety. General requirements*. It is the British Standard that covers the general safety requirements of a wide range of information technology equipment. BS EN 60950 Part 1 has been extensively revised to include amendments relating to changes in the Low Voltage Directive (LVD).
BS EN 60950-1 aims to help reduce the risks of fire, shock or injury to people coming into contact with IT equipment and to enable manufacturers to meet the needs of the European Low Voltage Directive. The standard aims to cover all foreseeable hazards, so it also takes into account hazards relating to heat, energy, mechanical, radiation and chemicals.
Included within the scope of BS EN 60950-1 are items of equipment with which office workers and members of the public are very familiar, such as cash dispensers, money processing machines, personal computers, visual display units, printers, photocopiers, shredding machines, calculators, dictation equipment, point-of-sale terminals and other retail equipment
A wide range of telecommunication equipment will also follow the requirements of this standard, such as base-stations, billing equipment terminals and facsimile machines.
To cover such a diverse range of equipment, the standard's primary focus is to outline the safety guidance. It then presents the various requirements, and follows these with the test methods that manufacturers can use to ensure that the equipment meets the requirements.
BS EN 60950-1 applies to mains-powered and battery-powered information technology equipment, including electrical business equipment and associated equipment, with a rated voltage not exceeding 600V.
It applies to information technology equipment that is:
- Designed for use as telecommunication terminal equipment and telecommunication network infrastructure equipment, regardless of the source of power
- Designed and intended to be connected directly to, or used as infrastructure equipment in, a cable distribution system, regardless of the source of power
- Designed to use the AC mains supply as a communication transmission medium
In addition, BS EN 60950-1 applies to components and subassemblies intended for incorporation in information technology equipment.
BS EN 60950-1 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.
Compared with the previous edition, BS EN 60950-1:2006+Amendment 1:2010 contains a number of important changes, including:
- Requirements for batteries enhanced
- Voltage texts for cable distribution systems clarified
- Alternative procedure for motor test added
- Requirements added to limit power output of data ports for additional equipment
- Definitions added
- More detailed requirements regarding clearance and shock hazard for DC mains supplies
- Tests clarified for limited power sources
- Tests clarified for mechanical strength
- Rules clarified for single-pole isolators
- More detail given to determine minimum rated operating voltage for surge suppressors
- Requirements clarified for VDRs in primary circuits
- Test procedure modified for wall-mounted equipment
- SELV circuit and TNV circuit requirements for separation aligned
- Overcurrent protective devices to be specified if required externally
- Requirements and text procedure modified for protective bonding conductors
