适用范围：1.1.1 This standard is applicable to information technology equipment, including electrical business equipment and associated equipment, with a rated voltage not exceeding 600 V.This standard specifies requirements intended to ensure safety for the operator and layman who may come into contact with the equipment and, where specifically stated, for service personnel.This standard is intended to ensure the safety of installed equipment, whether it consists of a system of interconnected units or independent units, subject to installing, operating and main-taining the equipment in the manner prescribed by the manufacturer.For equipment intended to be used in vehicles, on board ships or aircraft, in tropical countries, or at elevations greater than 2000 m, other requirements may be necessary.For equipment subject to transient overvoltages exceeding those for Installation Category II according to IEC Publi-cation 664: Insulation Co-ordination within Low-voltage Systems including Clearances and Creepage Distances for Equipment, additional protection might be necessary in the mains supply to the equipment.For equipment intended for use where ingress of water is possible, additional requirements may be necessary; for guidance on such requirements, and on relevant testing, see Appendix J.Examples of equipment which is within the scope of this standard are:— Data and text processing equipment, personal computers, visual display units, data preparation equipment, data terminal equipment, data circuit terminating equipment, typewriters, calculators, accounting and book-keeping machines, cash registers, point of sale terminals, paper tape readers and punchers, staplers, duplicators, copying machines, erasers, pencil sharpeners, mail processing machines, document shredding machines, magnetic tape handiers, motor-operated filés, dictation equipment, micrographic ofTice equipment, monetary processing machines, electrically operated drawing machines (plotters), paper trimmers (punchers, cutting machines, separators), paper jogging machines, postage machines and teleprinters.This list is not intended to be comprehensive, and equipment that is not listed is not necessarily excluded from the scope.Equipment complying with the relevant requirements in this standard is considered suitable for use with process control equipment, automatic test equipment and similar systems requiring information processing facilities. This standard does not include requirements for performance or functional characteristics of the equipment.Attention is drawn to the fact that the telecommunications authorities of some countries may impose additional requirements on information technology equipment which is to be connected to their networks. Those requirements generally concern the protection of the networks as well as the users of the equipment. It is assumed that adequate transient surge protection has been provided by the authorities.
