This document gives the definitions of different types of impedance in time domain and specifies the test method of these kinds of impedance. It’s applicable for determining the values of time domain impedance of twinax cables and twinax cable assemblies.

This part of IEC 60679 describes the general properties, performance characteristics and usage precautions for quartz crystal oscillators. This content mainly describes crystal oscillators, but some descriptions also apply to oscillators other than crystal units (e.g. MEMS resonators).

Replacement:

This part of the IEC 61851 series, together with [IEC 61851-1 Ed. 3] and [IEC 61851-23, Ed. 2.0], applies to the EV supply equipment to provide energy transfer between the supply network and electric vehicles (EVs), with a rated maximum voltage at side A (supply network side) up to 1 000 V AC or up to 1 500 V DC and a rated maximum voltage at side B (EV side) up to 1 250 V DC.

NOTE 1 A rated maximum voltage of the EV supply equipment at side B of 1 500 V DC is under consideration.

This document specifies the EV supply equipment of Megawatt Charging System (MCS) equipped with a coupler according to IEC TS 63379. Systems different to system MCS using a coupler specified in IEC TS 63379 are under consideration.

Requirements for bidirectional power flow systems are under consideration.

This document does not cover all safety aspects related to maintenance.

Requirements for systems not providing protective separation between side A (supply network side) and side B (EV side) are under consideration.

The requirements for digital communication between the EV supply equipment and the EV for control of energy transfer are defined in ISO 15118-10[1] and ISO 15118-20.

The specific requirements for EV supply equipment with multiple side Bs (EV sides) are provided in Annex FF.

General information of communication and the energy transfer process is described in Annex GG.

General information on the touch current and touch impulse current is provided in Annex HH.

EV supply equipment in compliance with this document is not intended to provide energy transfer to a single EV using:

multiple vehicle connectors of the same EV supply equipment; or

multiple EV supply equipments.

Requirements for such use case are not specified in this document, but are under consideration.

NOTE 2  The safety requirements of vehicle during charging are specified in ISO 5474 series.

NOTE 3  Requirements for an optional automated connection of system MCS are under preparation in IEC 61851-27.

Requirements for EVs mated to an EV supply equipment according to this document are specified in ISO 5474-3:2023, Annex B.

This document specifies the minimum operational and performance requirements, methods of testing and required test results conforming to performance standards adopted by the IMO in resolution MSC.74(69) Annex 2 Recommendation on Performance Standards for Track Control Systems. In addition, it takes into account IMO resolution A.694(17) to which IEC 60945 is associated. It also takes into account IMO resolution MSC.302(87) on bridge alert management (BAM), to which IEC 62923-1 and IEC 62923-2 are associated.

All text of this document that is identical to that in IMO resolution MSC.74(69), Annex 2, is printed in italics and the resolution (abbreviated to – A2) and paragraph numbers are indicated in brackets i.e. (A2/3.3).

This part of IEC 60794 describes test procedures to be used in establishing uniform requirements for optical fibre cables for the mechanical property - abrasion.

This document applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors.

Method E2A evaluates the ability of the sheath to resist abrasion; Method E2B evaluates the ability of cable markings (include text or graphic markers, and continuous colored lines on cable) to resist abrasion.

This part of IEC 61753 contains the minimum initial performance, test and measurement requirements and severities which plug-pigtail style and plug-receptacle style OTDR reflecting devices need to satisfy in order to be categorized as meeting the requirements of category C-Controlled environments, as defined in Annex A of IEC 61753-1 [1][1]. These devices are utilized for out-of-band OTDR testing of an optical fibre system.

Annex B provides information concerning these devices.

This part of IEC 63478-2 describes the requirements to measure user’s Quality of Experience (QoE) on multimedia conferencing services.

This International standard specifies three techniques for the determination of free Bisphenol A (BPA) in plastics of electrotechnical products.

The liquid chromatography – diode array detector (LC-DAD) and liquid chromatography mass spectrometry (LC-MS) and liquid chromatography tandem mass spectrometry (LC-MS/MS).  These test methods are described in the normative part of this standard. These test methods have been evaluated for use with PC, PC/ABS, PP matrices containing free BPA between 20 mg/kg to 500 mg/kg as shown in the Pre-IIS 13 results in Annex C and IIS 13 results in Annex D. The use of these methods for BPA concentration ranges of plastics, other than those specified in Annex C, Annex D has not been evaluated.
