Scope 1 IEC 60364-1 gives the rules for the design@ erection@ and verification of electrical installations. The rules are intended to provide for the safety of persons@ livestock and property against dangers and damage which may arise in the reasonable use of electrical installations and to provide for the proper functioning of those installations. IEC 60364-1 applies to the design@ erection and verification of electrical installations such as those of a) residential premises; b) commercial premises; c) public premises; d) industrial premises; e) agricultural and horticultural premises;?f) prefabricated buildings; g) caravans@ caravan sites and similar sites; h) construction sites@ exhibitions@ fairs and other installations for temporary purposes; i) marinas; j) external lighting and similar installations (see@ however @11.3e)); k) medical locations; l) mobile or transportable units; m) photovoltaic systems; n) low-voltage generating sets. NOTE?? ??Premises?? covers the land and all facilities including buildings belonging to it. IEC 60364-1 covers a) circuits supplied at nominal voltages up to and including 1 000 V a.c. or 1 500 V d.c.; ??? For a.c.@ the preferred frequencies which are taken into account in this standard are 50??? Hz@?60?Hz and 400 Hz. The use of other frequencies for special purposes is not excluded. b) circuits@ other than the internal wiring of apparatus@ operating at voltages exceeding 1 000 V and derived from an installation having a voltage not exceeding 1 000 V a.c.@ for example@ discharge lighting@ electrostatic precipitators;????c) wiring systems and cables not specifically covered by the standards for appliances; d) all consumer installations external to buildings; e) fixed wiring for information and communication technology@ signalling@ control and the like (excluding internal wiring of apparatus); f) the extension or alteration of the installation and also parts of the existing installation affected by the extension or alteration. NOTE?? The rules of IEC 60364-1 are intended to apply to electrical installations generally but@ in certain cases@ they may need to be supplemented by the requirements or recommendations of other IEC standards (for example@ for installations in explosive gas atmospheres). IEC 60364-1 does not apply to a) electric traction equipment@ including rolling stock and signaling equipment; b) electrical equipment of motor vehicles@ except those covered in Part 7; c) electrical installations on board ships and mobile and fixed offshore platforms; d) electrical installations in aircraft; e) public street-lighting installations which are part of the public power grid; f) installations in mines and quarries; g) radio interference suppression equipment@ except where it affects the safety of the installation; h) electric fences; i) external lightning protection systems for buildings (LPS); NOTE?? Atmospheric phenomena are covered in IEC 60364-1 but only insofar as effects on the electrical installations are concerned (for example@ with respect to selection of surge protective devices). j) certain aspects of lift installations; k) electrical equipment of machines. IEC 60364-1 is not intended to apply to ?C systems for distribution of energy to the public@ or ?C power generation and transmission for such systems. NOTE 1?? Countries wishing to do so may@ however@ use this standard in whole or in part for that purpose. NOTE 2?? According to IEC 61936 which provides common rules for the design and the erection of electrical power installations in systems with nominal voltages above 1kV a.c. and nominal frequency up to and including 60 Hz@ low- voltage a.c. and d.c. protection and monitoring systems should be in accordance with IEC 60364 series. Electrical equipment is dealt with only so far as its selection and application in the installation are concerned. This applies also to assemblies of electrical equipment complying with the relevant standards.??????????? 1 The numbering system is explained in Annex A.

This part of IEC 62059 provides one of several possible methods for estimating product life characteristics by accelerated reliability testing. Acceleration can be achieved in a number of different ways. In this particular standard, elevated, constant temperature and humidity is applied to achieve acceleration. The method also takes into account the effect of voltage and current variation. Of course, failures not (or not sufficiently) accelerated by temperature and humidity will not be detected by the application of the test method specified in this standard. Other factors, like temperature variation, vibration, dust, voltage dips and short interruptions, static discharges, fast transient burst, surges, etc. – although they may affect the life characteristics of the meter – are not taken into account in this standard; they may be addressed in future parts of the IEC 62059 series. This standard is applicable to all types of metering equipment for energy measurement, tariffand load control in the scope of IEC TC 13. The method given in this standard may be used for estimating (with given confidence limits) product life characteristics of such equipment prior to and during serial production. This method may also be used to compare different designs.
