31.220.20 - Switches

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 pe...view more

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 4...view more

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...view more

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.

EN IEC 62343-3-3 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 may be included for detailed product specifications or performance specifications. However, specification parameters specified in this standard shall not be removed from the detail product specifications or performance specificatio...view more

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...view more

for use in electrical and electronic appliances. Switches covered by this specification: 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 generic specification does not include keyboards and keypads which are intended for use in information-handling systems. Electromechanical key switches may be included under the scope of this ge...view more
