33.020 - Telecommunications in general

This document specifies terminology and definitions related to wireless power transfer (WPT)
technologies below 30 MHz to promote global harmonization of wireless power transfer
terminology.
This document does not address terminology of wireless power transfer outside the scope of
IEC TC 100 (Audio, video and multimedia systems and equipment), such as human exposure
or safety.

The present document has been produced to help a Technical Body (TB) to produce a Harmonised Standard (HS) covering the conformity of radio equipment with the essential requirements in articles 3.1(b) and 3.2 of the Radio Equipment Directive (Directive 2014/53/EU [i.1]).
NOTE 1: Article 3.1(b) of Directive 2014/53/EU [i.1] states:
"Radio equipment shall be constructed so as to ensure….an adequate level of electromagnetic compatibility as set out in Directive 2014/30/EU."
NOTE 2: Article 3.2 o...view more

This document specifies basic requirements for the installation of media for communication networks within and between the automation islands, of industrial sites. This standard covers balanced and optical fibre cabling. It also covers the cabling infrastructure for wireless media, but not the wireless media itself. Additional media are covered in the IEC 61784-5 series. This document is a companion standard to the communication networks of the industrial automation islands and especially to the...view more

This part of IEC 60027 is applicable to telecommunications and electronics. It gives names
and symbols for quantities and their units.

Defines rules for the use and writing of letter symbols for telecommunications and electronics.

ISO/IEC 21823-1:2019(E) provides an overview of interoperability as it applies to IoT systems and a framework for interoperability for IoT systems. This document enables IoT systems to be built in such a way that the entities of the IoT system are able to exchange information and mutually use the information in an efficient way. This document enables peer-to-peer interoperability between separate IoT systems.
This document provides a common understanding of interoperability as it applies to IoT...view more

This document specifies procedures for measuring and reporting the noise emission of information
technology and telecommunications equipment.
NOTE 1 This document is considered part of a noise test code (see 3.1.2) for this type of equipment and is
based on basic noise emission standards (see 3.1.1) ISO 3741, ISO 3744, ISO 3745, ISO 9295 and ISO 11201.
The basic emission quantity is the A-weighted sound power level, which can be used for comparing
equipment of the same type but from differe...view more

IEC 60027-2:2019 is applicable to telecommunications and electronics. It gives names and symbols for quantities and their units.

IEC 61918:2018 specifies basic requirements for the installation of media for communication networks in industrial premises and within and between the automation islands, of industrial sites. This standard covers balanced and optical fibre cabling. It also covers the cabling infrastructure for wireless media, but not the wireless media itself. Additional media are covered in the IEC 61784-5 series. This fourth edition cancels and replaces the third edition published in 2013. This edition constit...view more

The present document specifies technical characteristics and methods of measurements for audio frequency induction
loop amplifiers and receivers operating from 10 Hz to 9 kHz used in audio frequency induction loop systems (AFILS).
NOTE: The object of an AFILS is to transmit an audio signal to people with hearing difficulties. The receiver in
this case is normally a hearing aid with a built in telecoil.
These radio equipment types are capable of operating in the frequency band within the 10 H...view more
