IEC 61156-6-1:2009(E) describes symmetrical pair/quad cables intended primarily for horizontal floor cabling as defined in ISO/IEC 11801 and ISO/IEC 24702. It includes additional recommended environmental characteristics and severities which are derived from the environmental classifications that are specified for cabling for various environments. This edition constitutes a technical revision and includes the following significant technical changes with respect to the previous edition:
- new requirements for new cables Cat6A and Cat7A;
- revised requirements and tests for the cables.
This publication is to be read in conjunction with IEC 61156-1:2007 and IEC 61156-6:2007.

IEC 63138-2:2020, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for MQ4 series circular connectors with four RF channels, as well as a detailed specification of the blank format. An MQ4 series circular connector with 50 Ω nominal impedance has four RF channels which can be engaged and disengaged at the same time. There are two versions of plug connectors, one is a quick-lock version, and the other is a threaded version. The socket connector provides two coupling mechanisms, a quick-lock and a threaded coupling.
This document also specifies the mating face dimensions and gauging information of MQ4 series circular connectors, and tests selected from IEC 63138-1, applicable to all detail specifications relating to MQ4 series circular connectors.

IEC 63185:2020 relates to a measurement method for complex permittivity of a dielectric substrates at microwave and millimeter-wave frequencies. This method has been developed to evaluate the dielectric properties of low-loss materials used in microwave and millimeter-wave circuits and devices. It uses higher-order modes of a balanced-type circular disk resonator and provides broadband measurements of dielectric substrates by using one resonator, where the effect of excitation holes is taken into account accurately on the basis of the mode-matching analysis.

IEC TS 61169-1-51:2020 relates to radio frequency connectors for RF transmission lines for use in telecommunications, electronics and similar equipment. It provides the technical report for the uncertainty specifications for return loss measurements, which apply to individual connector types, by vector network analysers (VNAs). It is intended to establish concepts and procedures considering:
– testing and measuring procedures concerning frequency domain electrical properties;
– uncertainty specifications of VNAs measurements for return loss of RF connectors.
The test methods and procedures of this document are intended for acceptance and type approval testing.
