This part of IEC 62822, which is a product family standard, applies to equipment for
resistance welding, arc welding and allied processes designed for occupational use by
professionals and for use by laymen.
NOTE 1 Typical allied processes are resistance hard and soft soldering, resistance heating by means comparable
to resistance welding equipment, electric arc cutting and arc spraying.
The frequency range covered is 0 Hz to 300 GHz.
This product family standard specifies assessment metho...view more

This International Standard specifies the rules for signs and reference directions and
reference polarities for electric currents and voltages in electric networks.
In Clauses 3 to 10, the time dependence is arbitrary. It is assumed that the wavelength of the
highest frequency involved is larger than the largest distance between two points of the
network; processes are considered to be quasi-static. Clause 11 specifies the rules and
recommendations for complex notation.

This European Standard provides a general procedure to assess workers’ exposure to electric and magnetic fields (EMF) in work places associated with the production, transmission and distribution of electric energy, and to demonstrate compliance with exposure limit values and action levels as stated in the Council and European Parliament “EMF” Directive 2013/35/EU [10].
It has the role of a specific workplace standard. It takes into account the non-binding application guide for implementing the ...view more

IEC TR 61916:2017(E) provides guidance on requirements and tests for subjects applicable to electrical accessories that are within the scope of IEC TC 23 and its subcommittees.
This fourth edition cancels and replaces the third edition published in 2014 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) clarification of the introduction and the scope;
b) clarification of subclause 6.3;
c) modificati...view more

IEC 60127-5:2016 gives a guide for tests for assessing the quality of miniature fuse-links other than type tests, for the case where there is no complete agreement between the user and the manufacturer on what such tests apply. This document provides guidelines and limits generally acceptable for quality control purposes by large scale users and manufacturers of miniature fuse-links. This document has validity for large scale series with lot sizes of 10 000 and more. It is also applicable for sm...view more

This part of IEC 61000 specifies the immunity requirements, test methods, and range of
recommended test levels for equipment subjected to impulse magnetic disturbances mainly
encountered in:
– industrial installations,
– power plants,
– railway installations,
– medium voltage and high voltage sub-stations.
The applicability of this standard to equipment installed in different locations is determined by
the presence of the phenomenon, as specified in Clause 4.
This standard does not cons...view more

IEC 62679-3-3:2016(E) specifies the standard measurement conditions and measurement methods for determining the optical performance of electronic paper display (EPD) devices which have an operating integrated lighting unit (such as a front light). The scope of this document is restricted to EPDs using segmented or matrix structures with either monochromatic or colour type displays. The measurement methods are intended for EPDs operated in a reflective mode with the integrated lighting unit (ILU)...view more

IEC 60909-0:2016 is applicable to the calculation of short-circuit currents in low-voltage three-phase AC systems, and in high-voltage three-phase AC systems, operating at a nominal frequency of 50 Hz or 60 Hz. It establishes a general, practicable and concise procedure leading to results which are generally of acceptable accuracy and deals with the calculation of short-circuit currents in the case of balanced or unbalanced short circuits. This second edition cancels and replaces the first editi...view more

This International Standard applies to the assessment of lighting equipment related to human
exposure to electromagnetic fields. The assessment consists of the induced internal electric
field for frequencies from 20 kHz to 10 MHz and the specific absorption rate (SAR) for
frequencies from 100 kHz to 300 MHz around lighting equipment.
Included in the scope of this standard are:
– all lighting equipment with a primary function of generating and/or distributing light
intended for illumination...view more

IEC TR 60865-2:2015(E) shows the application of procedures for the calculation of mechanical and thermal effects due to short circuits as presented in IEC 60865-1. Thus, this technical report is an addition to IEC 60865-1. It does not, however, change the basis for standardized procedures given in that publication. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision. It includes the following changes. The determinations for auto reclo...view more

In IEC 80000-6:2008, names, symbols, and definitions for quantities and units of electromagnetism are given. Where appropriate, conversion factors are also given. International Standard IEC 80000-6 has been prepared by IEC technical committee 25: Quantities and units, and their letter symbols in close cooperation with ISO/TC 12, Quantities, units, symbols, conversion factors. This first edition of IEC 80000-6 cancels and replaces the second edition of ISO 31-5, published in 1992, and its amendme...view more
