This part of IEC 61020 specifies the terminology, symbols, test methods and other necessary information to provide consistency in detail specifications for electromechanical switches. This document relates to electromechanical switches intended for use in electrical and electronic appliances. Switches covered by this document: a) are devices which open, close, or change the connection of a circuit by the mechanical motion of conducting parts (contacts); b) have a maximum rated voltage of 480 V; c) have a maximum rated current of 63 A. This document does not include keyboards and keypads which are intended for use in information-handling systems. Electromechanical key switches can be included under the scope of this document. Switch families will be described in any detail specifications that reference this document. This document is a performance standard intended to describe evaluation methods to better clarify the capabilities of a switch. NOTE 1 Safety requirements for switches for household and similar fixed electrical installations are given in IEC 60669 (all parts). NOTE 2 Safety requirements for appliance switches are given in IEC 61058 (all parts).

This part of IEC 62343 provides a performance specification template for wavelength selective
switches. The object is to provide a framework for the preparation of detail specifications on the
performance of wavelength selective switches.
Additional specification parameters are often included for detailed product specifications or
performance specifications if necessary. However, specification parameters specified in this
document are not removed from the detail product specifications or performance specifications.
The technical information regarding wavelength selective switches and their applications in
DWDM systems with single-mode fibres are described in IEC TR 62343-6-4.

IEC 62625-2:2016 covers the standardized test methods for verifying the compliance of an On board Driving Data Recording System implementation with the requirements specified by IEC 62625-1. It also covers the conformity testing criteria for designed and manufactured ODDRS. This part of IEC 62625 includes the list of the requirements specified by IEC 62625-1 and the relevant acceptance conditions for ODDRS at design review, type test and routine test phases. For the train level design review and train level test phases, this part provides guidelines for the conformity testing methods to be applied to the ODDRS installed on the train.

This part of IEC 60876 applies to fibre optic switches possessing all of the following general
features:
– they are passive in that they contain no optoelectronic or other transducing elements;
– they have one or more ports for the transmission of optical power and two or more states
in which power may be routed or blocked between these ports;
– the ports are optical fibres or fibre optic connectors.

IEC 61000-3-3:2013 is available as IEC 61000-3-3:2013 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 61000-3-3:2013 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by an equipment tested under specified conditions and gives guidance on methods of assessment. It is applicable to electrical and electronic equipment having an input current equal to or less than 16 A per phase, intended to be connected to public low-voltage distribution systems of between 220 V and 250 V line to neutral at 50 Hz, and not subject to conditional connection. IEC 61000-3-3 has the status of a product family standard within the IEC 61000 series. This third edition cancels and replaces the second edition published in 2008. This edition constitutes a technical revision which takes account of the changes made in IEC 61000-4-15:2010.
