IEC 60794-1-403:2021 specifies a method of verifying that cable metallic elements are electrically continuous throughout the cable. Electrical continuity is important for bonding and grounding, toning for location, and other related system issues, and may represent a "goodness of manufacture" criterion. Typically, the test is one of continuity and carries no resistance or conductivity requirement. The metallic elements can be tested individually or can be tested as a total group. Since this latter criterion is frequently the case, all elements are measured as a group unless specified otherwise. NOTE It is possible detail specifications allow such elements as strength members to be non-continuous throughout the cable. This is a special case, and attention is directed to the detail specification.

IEC 62228-5:2021(E) specifies test and measurement methods for EMC evaluation of Ethernet transceiver ICs under network condition.

This part of IEC 61970 specifies a standard interface for exchanging dynamic model information
needed to support the analysis of the steady state stability (small-signal stability) and/or
transient stability of a power system or parts of it. The schema(s) for expressing the dynamic
model information are derived directly from the CIM, more specifically from IEC 61970-302.
The scope of this document includes only the dynamic model information that needs to be
exchanged as part of a dynamic study, namely the type, description and parameters of each
control equipment associated with a piece of power system equipment included in the steady
state solution of a complete power system network model. Therefore, this profile is dependent
upon other standard profiles for the equipment as specified in IEC 61970-452, CIM static
transmission network model profiles, the topology, the steady state hypothesis and the steadystate
solution (as specified in IEC 61970-456, Solved power system state profiles) of the power
system, which bounds the scope of the exchange. The profile information described by this
document needs to be exchanged in conjunction with IEC 61970-452 and IEC 61970-456
profiles’ information to support the data requirements of transient analysis tools. IEC 61970-456
provides a detailed description of how different profile standards can be combined to form
various types of power system network model exchanges.
This document supports the exchange of the following types of dynamic models:
• standard models: a simplified approach to exchange, where models are contained in
predefined libraries of classes interconnected in a standard manner that represent dynamic
behaviour of elements of the power system. The exchange only indicates the name of the
model along with the attributes needed to describe its behaviour.
• proprietary user-defined models: an exchange that would provide users the ability to
exchange the parameters of a model representing a vendor or user proprietary device where
an explicit description of the model is not described in this document. The connections
between the proprietary models and standard models are the same as described for the
standard models exchange. Recipient of the data exchange will need to contact the sender
for the behavioural details of the model.
This document builds on IEC 61970-302, CIM for dynamics which defines the descriptions of
the standard dynamic models, their function block diagrams, and how they are interconnected
and associated with the static network model. This type of model information is assumed to be
pre-stored by all software applications hence it is not necessary to be exchanged in real-time
or as part of a dynamics model exchange.

This part of IEC 60794, which is a family specification, specifies the optical fibre, cable elements,
cable construction requirements, main requirements for installation and operating conditions,
cable design characteristics and test for OPPC (optical phase conductor), used for carrying
current as well as communication and data transmission. The corresponding environmental
declaration can be built according to IEC TR 62839-1.
The OPPC is a substitute for a conventional phase bare conductor containing optical fibres.
Usually, the fibres are embedded loosely in protective buffer tubes. To fulfil mechanical and
electrical requirements, an armouring of one or more layers with aluminium, aluminium alloy,
and aluminium clad steel, galvanized steel or a mixture of them is helically stranded.

The scope of this document is to guide users of the EN 45545 series, particularly EN 45545 2:2013+A1:2015 and EN 45545 5:2013+A1:2015, in the application of these standards in designing and assessing NiCd batteries on board trains for their fire protection measures.
The scope of this document excludes any new requirements, considering only the requirements stated by the above listed standards.
However, EN 45545 being generic requirements and not specifically referred to NiCd batteries, this guide helps the application for those batteries.

• has to be considered in conjunction with and at the same level as IEC 61513. These two
standards provide a complete framework establishing general requirements for
instrumentation, control, and Electrical Power System for Nuclear Power Plants.
This document establishes:
• the high level specification and requirement to implement a suitable Electrical Power
System in a NPP that supports reactor systems important to safety. It also enables
electrical energy production providing the transmission grid with active and reactive power
and electro-mechanical inertia;
• the relationships between:
– the plant safety requirements and the architecture of the overall Electrical Power
System and its sub-systems (see Figure 1) including:
a) the contribution to the plant Defence in Depth;
b) the independency and redundancy provisions;
– the electrical requirements and the architecture of the Electrical Power System and its
sub-systems;
– the functional requirements and the architecture of the Electrical Power System and its
sub-systems;
– the requirements associated with the maintenance strategy and the architecture of the
Electrical Power System and its sub-systems;
• the design of Electrical power sub-systems (e.g. interruptible and uninterruptible);
• the requirements for supporting systems of Electrical Power System (HVAC, I&C, etc.);
• the Electrical Power System life-cycle framework.
This document does not cover the specification of:
• I&C systems;
• the transmission lines connecting to substations outside the NPP;
• electrical equipment requirements already defined in the industrial IEC standards;
• electrical power for security systems (e.g., fences, surveillance systems, entrance
control);
• lighting and socket facility.
This document does not consider power production requirements.

This part of IEC 61753 contains the minimum tests, test severities and measurement
requirements which a sealed fibre optic closure need to meet in order to be categorised as
meeting the IEC standard for category G – Ground, as defined in Table A.14 of
IEC 61753-1:2018. Free breathing closures are not covered in this document.

This part of IEC 63203-201 specifies a test method for determination of the electrical resistance
of conductive fabrics under simulated microclimate within clothing. The microclimate is the
climate of the small air layer between the skin and clothing having a specific temperature and
humidity. This test method can be applied to conductive fabrics including multilayer assemblies
for use in clothing.

This part of IEC 61439 lays down the general definitions and service conditions, construction
requirements, technical characteristics and verification requirements for low-voltage
switchgear and controlgear assemblies.
NOTE Throughout this document, the term assembly(s) (see 3.1.1) is used for a low-voltage switchgear and
controlgear assembly(s).
For the purpose of determining assembly conformity, the requirements of the relevant part of
the IEC 61439 series, Part 2 onwards, apply together with the cited requirements of this
document. For assemblies not covered by Part 3 onward, Part 2 applies.
This document applies to assemblies only when required by the relevant assembly standard
as follows:
– assemblies for which the rated voltage does not exceed 1 000 V AC or
1 500 V DC;
– assemblies designed for a nominal frequency of the incoming supply or supplies not
exceeding 1 000 Hz;
– assemblies intended for indoor and outdoor applications;
– stationary or movable assemblies with or without an enclosure;
– assemblies intended for use in connection with the generation, transmission, distribution
and conversion of electric energy, and for the control of electrical energy consuming
equipment.
This document does not apply to individual devices and self-contained components such as
motor starters, fuse switches, power electronic converter systems and equipment (PECS),
switch mode power supplies (SMPS), uninterruptable power supplies (UPS), basic drive
modules (BDM), complete drive modules (CDM), adjustable speed power drives systems
(PDS), and other electronic equipment which comply with their relevant product standards.
This document describes the integration of devices and self-contained components into an
assembly or into an empty enclosure forming an assembly.
For some applications involving, for example, explosive atmospheres, functional safety, there
can be a need to comply with the requirements of other standards or legislation in addition to
those specified in the IEC 61439 series.

This European Standard specifies the minimum equipment requirements for the performance, reliability, resilience, security and safety characteristics of the receiving centre transceiver (RCT) installed in ARC and used in alarm transmission systems. The alarm transmission system requirements and classifications are defined within EN 50136 1. Different types of alarm systems may in addition to alarm messages also send other types of messages, e.g. fault messages and status messages. These messages are also considered to be alarm messages. The term alarm message is used in this broad sense throughout the document.  Where application specific standards exist, the RCT should comply with relevant standards called up by that application. The RCT can be either an integrated element of any receiving/annunciation equipment, or a stand-alone device. In either case, the requirements of this European Standard should apply. The function of the RCT is to monitor the ATPs, receive alarm messages, forward alarm messages to one or more AEs and send acknowledgements to the SPTs. Management of the transmission network is not in the scope of this European Standard.
