Code of practice for hearing-loop systems (HLS)

Published by: 2017-04-10 / 2017-04-10 / 103 pages
IEC TR 63079:2017(E) gives recommendations for and guidance on the design, planning, installation, testing, operation and maintenance of a hearing-loop system (HLS) intended for communicating speech, music and/or other signals. It is mainly concerned with HLS for hearing enhancement, in which the signals are communicated to users of hearing aids equipped with magnetic pick-up coils.
This document does not apply to induction-loop systems which use a carrier frequency, nor to other systems for hearing enhancement purposes which do not use magnetic induction.

Electronic display devices – Part 2-3: Measurements of optical properties – Multi-colour test patterns

Published by: 2017-03-09 / 2017-03-09 / 16 pages
IEC TR 62977-2-3:2017 (E), which is a Technical Report, reviews the impact of test pattern colour content and image loading on the measured display's photometric and colorimetric performance. Experimental data for several display technologies is presented to demonstrate the need for using a broader range of colours in the test patterns, and measuring the display at an image loading level appropriate for the intended application.

Live working – Voltage detectors – Part 6: Guidelines on non-contact voltage detectors (NCVD) for use at nominal voltages above 1 kV AC

Published by: 2017-03-03 / 2017-03-03 / 39 pages

IEC TR 61243-6:2017(E)  is applicable to portable non-contact voltage detectors (NCVD) with built-in power source, to be used to indicate the presence or the absence of the operating voltage on electrical systems for nominal voltages above 1 kV AC and frequencies of 16 2/3 Hz, 50 Hz and/or 60 Hz. This document describes only devices, and their behaviour, using electric field and voltage gradient detection principles even if other principles could be used. It provides performance guidelines, recommendations for use and recommended minimum criteria for selection.

Power systems management and associated information exchange – Part 1: Reference architecture

Published by: 2016-11-18 / 2016-11-18 / 111 pages
IEC TR 62357-1:2016(E) provides a clear and comprehensive map of all standards which are contributing to support interactions, in an open and interoperable way, between actors, components and systems in the field of electricity grids from generation to consumers, including transmission and distribution. The document also brings the vision of the path which will be followed by the concerned IEC technical committees and working groups in the coming years, to improve the global efficiency, market relevancy and coverage of this series of standards. This second edition includes the following significant technical changes with respect to the previous edition:
– it provides updates and defines layered Reference Architecture to help direct longer term goals and activities, specifically to ensure compatibility of all new standards developed in the IEC by benefitting from lessons learned during development of the current standards and their application to actual utility projects as well as through application of other internationally recognized architecture standards.
– It reflects the most recent editions of the IEC standards relating to power systems management and associated information exchange, including the IEC 61850 series and the IEC 61968, IEC 61970 and IEC 62325 Common Information Model (CIM) standards.
