IEC's activities, collectively known as electrotechnology, cover all electrical, electronic and associated technologies in the areas of power generation, transmission and distribution, medical equipment, semiconductors, fibre optics, nanotechnology and renewable energies. In addition to providing an excellent framework for improving safety and optimizing energy, IEC standards support trade between countries by providing a reference for the functioning of the World Trade Organization (WTO) Agreement on Technical Barriers to Trade.
Primarily for application to static protection relays, and acceptance criteria to be satisfied during and subsequent to the tests. Also defines test severity classes for relays and the relevant terminology. To be read in conjunction with BS 142:Part 0
General requirements for tests of static measuring relays and protection equipment with or without output contacts. Includes definitions of terms used, severity classes, test conditions and procedure and criteria for acceptance. To be read in conjunction with BS 142:Part 0
Particular requirements for dependent specified time electrical measuring relays of both the total and partial memory function type. Also provides requirements for thermal electrical relays for motor protection.
Specifies test to enable the performance of a machine to be confirmed and provides a basis for its suitability for a specified duty and for comparison with other machines.
Colour code for fixed resistors; letter and digit code for resistance and capacitance values; letter code for tolerance on resistance and capacitance values and data code for capacitors and resistors. Applicable only to marking on the body.
Characteristics, technical requirements, test methods for type, batch or whole production testing.
Characteristics, technical requirements and the test methods to be used for type, batch or whole production testing.
Requirements for sensors whose electrical resistance is a defined function of temperature. Covers thermometers suitable for all or part of the temperature range -150°C to 850°C. These are in the main sheathed elements suitable for immersion in the medium whose temperature is to be measured.
General information on environmental testing procedures and severities of tests designed to assess the durability of electrotechnical products under conditions of use, transport and storage.
Test Ba: Dry heat for non-heat-dissipating specimen with sudden change of temperature. Test Bb: Dry heat for non-heat-dissipating specimen with gradual change of temperature. Test Bc: Dry heat for heat-dissipating specimen with sudden change of temperature. Test Bd: Dry heat for heat-dissipating specimen with gradual change of temperature.
Primarily intended to permit observation of the effect of high humidity at constant temperature without condensation on electrotechnical products over a prescribed period. Intended to assess the suitability of electrotechnical products for use and storage under high humidity conditions. To be read in conjunction with BS 2011:Part 1.1
To assess the effects on a specimen of simple standard tests intended to be representative of the falls likely to be experienced during rough handling, or to demonstrate a minimum degree of robustness, for assessing safety requirements. An appendix gives guidance on the application of the test.
Method of test for determining the ability of a specimen of an electrotechnical product, primarily accessories such as switches and lampholders, to withstand specified severities of impact. It is mainly used to demonstrate an acceptable level of mechanical robustness when assessing the 'safety' of the product. To be read in conjunction with BS 2011:Part 1.1
Applicable to all electrotechnical products for the determination of structural suitability and satisfactory performance when subjected to forces produced by steady state acceleration environment and as a test of structural integrity of certain components.
Two variations of a test to determine the extent of mould growth and deterioration effects in assembled specimens whether or not constructed from mould resistant materials. To be read in conjunction with BS 2011:Part 1.1
