1.1.2 This standard applies to apparatus with a rated supply voltage not exceeding
—250 V a.c. single phase or d.c. supply;
—433 V a.c. in the case of apparatus for connection to a supply other than single-phase.
1.1.3 This standard applies to apparatus for use at altitudes not exceeding 5000 m above sea level, primarily in dry locations and in regions with moderate or tropical climates.
For apparatus with protection against splashing water, additional requirements are given in annex A.
For apparatus to be connected to telecommunication networks, additional requirements are given in annex B.
For apparatus intended to be used in vehicles, ships or aircraft, or at altitudes exceeding 5000 m above sea level, additional requirements may be necessary.
Note: See Table A.2 of GB/T 16935.1.
Requirements, additional to those specified in this standard, may be necessary for apparatus intended for special conditions of use.
1.1.4 For apparatus designed to be fed from the mains, this standard applies to apparatus intended to be connected to a mains supply with transient overvoltages not exceeding overvoltage category II according to GB/T 16935.1.
For apparatus subject to transient overvoltages exceeding those for overvoltage category II, additional protection may be necessary in the mains supply of the apparatus.
