EN IEC 62351-3:2023(Main)
Power systems management and associated information exchange - Data and communications security - Part 3: Communication network and system security - Profiles including TCP/IP
SIST EN IEC 62351-3:2023

IEC 62351-3:2023 specifies how to provide confidentiality, integrity protection, and message level authentication for protocols that make use of TCP/IP as a message transport layer and utilize Transport Layer Security when cyber-security is required. This may relate to SCADA and telecontrol protocols, but also to additional protocols if they meet the requirements in this document. IEC 62351-3 specifies how to secure TCP/IP-based protocols through constraints on the specification of the messages, procedures, and algorithms of Transport Layer Security (TLS) (TLSv1.2 defined in RFC 5246, TLSv1.3 defined in RFC 8446). In the specific clauses, there will be subclauses to note the differences and commonalities in the application depending on the target TLS version. The use and specification of intervening external security devices (e.g., "bump-in-the-wire") are considered out-of-scope. In contrast to previous editions of this document, this edition is self-contained in terms of completely defining a profile of TLS. Hence, it can be applied directly, without the need to specify further TLS parameters, except the port number, over which the communication will be performed. Therefore, this part can be directly utilized from a referencing standard and can be combined with further security measures on other layers. Providing the profiling of TLS without the need for further specifying TLS parameters allows declaring conformity to the described functionality without the need to involve further IEC 62351 documents. This document is intended to be referenced as a normative part of other IEC standards that have the need for providing security for their TCP/IP-based protocol exchanges under similar boundary conditions. However, it is up to the individual protocol security initiatives to decide if this document is to be referenced. The document also defines security events for specific conditions, which support error handling, security audit trails, intrusion detection, and conformance testing. Any action of an organization in response to events to an error condition described in this document are beyond the scope of this document and are expected to be defined by the organization’s security policy. This document reflects the security requirements of the IEC power systems management protocols. Should other standards bring forward new requirements, this document may need to be revised. This second edition cancels and replaces the first edition published in 2014, Amendment 1:2018 and Amendment 2:2020. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Inclusion of the TLSv1.2 related parameter required in IEC 62351-3 Ed.1.2 to be specified by the referencing standard. This comprises the following parameter: • Mandatory TLSv1.2 cipher suites to be supported. • Specification of session resumption parameters. • Specification of session renegotiation parameters. • Revocation handling using CRL and OCSP. • Handling of security events. b) Inclusion of a TLSv1.3 profile to be applicable for the power system domain in a similar way as for TLSv1.2 session.

EN IEC 60728-101-1:2023(Main)
Cable networks for television signals, sound signals and interactive services - Part 101-1: RF cabling for two-way home networks with all-digital channels load
SIST EN IEC 60728-101-1:2023

IEC 60728-101-1:2023 provides the requirements and describes the implementation guidelines of RF cabling for two-way home networks; it is applicable to any home network that distributes signals provided by CATV/MATV/SMATV cable networks (including individual receiving systems) having a coaxial cable output. It is also applicable to home networks where some part of the distribution network uses wireless links, for example in place of the receiver cord. This part of IEC 60728 is therefore applicable to RF cabling for two-way home networks with wired cords or wireless links inside a room and primarily intended for television and sound signals operating between about 5 MHz and 3 300 MHz. The frequency range is extended to 6 000 MHz for distribution techniques that replace wired cords with a wireless two-way communication inside a room (or a small number of adjacent rooms) that uses the 5 GHz to 6 GHz band. In a building divided into apartment blocks, the distribution of the signals inside the home starts from the home network interface (HNI) up to the system outlet or terminal input. The requirements at the system outlet are given in IEC 60728-101:2016, Clause 5 and the requirements at the HNI are given in IEC 60728-101:2016, Clause 7. In Clause 5 of this document, additional requirements are given. This document deals with various possibilities to distribute signals in a home network, using coaxial cables, balanced pair cables, fibre optic cables (glass or plastic) and also wireless links inside a room (or a small number of adjacent rooms) to replace wired cords. This document gives references to basic methods of measurement of the operational characteristics of the home cable network in order to assess its performance. All requirements refer to the performance limits, which are obtained between the input(s) at the home network interface (HNI) and the output at any system outlet when terminated in a resistance equal to the nominal load impedance of the system, unless otherwise specified. Where system outlets are not used, the above applies to the terminal input. The present document also provides limits for the accumulation of degradations if the home network is subdivided into a number of parts, using different transmission media (e.g. coaxial cabling, balanced cabling, optical cabling, wireless links). Clause 5 defines the performance limits measured at system outlet or terminal input for an unimpaired (ideal) test signal applied at the HNI. Under normal operating conditions for any digital channel and meeting these limits, the cumulative effect of the impairment of any single parameter at the HNI and that due to the home network produces signals not worse than the requirements given in IEC 60728-101-2. For digitally modulated signals, the quality requirement is a QEF (quasi error-free) reception. This document describes the physical layer connection for home networks. Description of protocols required for layer 2 and higher layers is out of the scope of this document. Logical connections between devices within the home network are therefore not always guaranteed. This International Standard is to be used in conjunction with IEC 60728-101:2016.

EN IEC 61000-4-6:2023(Main)
Electromagnetic compatibility (EMC) - Part 4-6: Testing and measurement techniques - Immunity to conducted disturbances, induced by radio-frequency fields
SIST EN IEC 61000-4-6:2023

This part of IEC 61000 relates to the conducted immunity requirements of electrical and electronic equipment to electromagnetic disturbances coming from intended radio-frequency (RF) transmitters in the frequency range 150 kHz up to 80 MHz. NOTE 1 Product committees might decide to use the methods described in this document also for frequencies up to 230 MHz (see Annex B) although the methods and test instrumentation is intended to be used in the frequency range up to 80 MHz. Equipment not having at least one conducting wire and/or cable (such as mains supply, signal line or earth connection) which can couple the equipment to the disturbing RF fields is excluded from the scope of this publication. NOTE 2 Test methods are specified in this part of IEC 61000 to assess the effect that conducted disturbing signals, induced by electromagnetic radiation, have on the equipment concerned. The simulation and measurement of these conducted disturbances are not adequately exact for the quantitative determination of effects. The test methods specified are structured for the primary objective of establishing adequate repeatability of results at various facilities for quantitative analysis of effects. The object of this standard is to establish a common reference for evaluating the functional immunity of electrical and electronic equipment when subjected to conducted disturbances induced by RF fields. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against a specified phenomenon. NOTE 3 As described in IEC Guide 107, this standard is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria.

Cable networks for television signals, sound signals and interactive services - Part 101-2: Performance requirements for signals delivered at the system outlet in operation with all-digital channels load
SIST EN IEC 60728-101-2:2023

IEC 60728-101-2:2023 provides the minimum performance requirements to be fulfilled in operation at the system outlet or terminal input and describes the summation criteria for the impairments present in the received signals and those produced by the CATV/MATV/SMATV cable network, including individual receiving systems. In a building divided into apartment blocks, the signals received by the antennas are distributed by the MATV/SMATV cable network up to the home network interface (HNI); the television signals are then distributed (inside the home) by home networks (HN) of various types up to the system outlet or terminal input. The cable network can support two-way operation, from the system outlet (or terminal input) towards the headend. The home network can use coaxial cables, balanced pair cables, fibre optic cables (glass or plastic) and also wireless links inside a room (or a small number of adjacent rooms) to replace wired cords. This part of IEC 60728 is limited to downstream TV broadcast signals received from antennas and is applicable to cable networks intended for television signals, sound signals and interactive services operating between about 5 MHz and 3 300 MHz. The frequency range is extended to 6 000 MHz for home distribution techniques that replace wired cords with a wireless two-way communication inside a room (or a small number of adjacent rooms) that uses the 5 GHz to 6 GHz frequency band. The main sections of a general CATV/MATV/SMATV system, indicating the parts of the IEC 60728-101 series documents where the relevant performance requirements are indicated. - The requirements for the signals received at the headend are given in IEC 60728-101:2016, Clause 6. - The requirements for the CATV/MATV/SMATV cable network, assuming an unimpaired input signal at the input of the headend, up to the system outlet are given in IEC 60728‑101:2016, Clause 5. - The requirements for the CATV/MATV/SMATV cable network up to the home network interface (HNI) are given in IEC 60728-101:2016, Clause 7, assuming an unimpaired input signal at the input of the headend. - The specific requirements from HNI to the system outlet or terminal input are given in IEC 60728-101-1:2023, Clause 5, assuming an unimpaired input signal at the HNI. - The requirements at the system outlet in operation are given in Clause 6 of this document. The expression "in operation" means that the received signals, with their impairments, are applied to the headend input of the CATV/MATV/SMATV cable network. The requirements at the system outlet "in operation" are derived, therefore, by summing the impairments of the various cascaded parts of the system and of the input signal. When a change of signal format from digital to digital (e.g. from QPSK to QAM) (e.g. as in ETSI EN 300 473) or from digital to analogue (e.g. from DVB-S/S2 to AM-VSB or DVB-T/T2 to AM-VSB) is made at the headend, the summation of the impairments that produce a relaxation of requirements at system outlet does not apply. Such a case will be the equivalence of unimpaired signals applied at the headend input. Therefore, the requirements at system outlet given in IEC 60728‑1 apply. This document also provides references for the basic methods of measurement of the operational characteristics of the downstream cable network in order to assess its performance. All requirements refer to the performance limits to be achieved in operation at any system outlet when terminated in a resistance equal to the nominal load impedance of the system, unless otherwise specified.

Fibre management systems and protective housings to be used in optical fibre communication systems - Product specifications - Part 3-2: Single-mode mechanical fibre splice
SIST EN 50411-3-2:2023

1.1 Product definition This document contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements, which single mode mechanical splice needs to meet in order for it to be categorized as a European standard product. Although, in this document, the product is qualified for EN IEC 60793 2 50 type B-652.D single mode fibres, it is also suitable for mechanical splicing of other single mode fibres with 125 µm diameter glass cladding. Also mechanical splices designed for connections of buffered or secondary coated fibres and cords according to EN 60794 2 50:2008 are covered by this document. 1.2 Interoperability The installed mechanical splice fits into optical fibre management system with optical splice cassettes or splice trays as defined in EN IEC 61756 1. This document specifies the following two physical interface dimensions: - cross sectional profile with width, height or diameter (in millimetres); - length (in millimetres). 1.3 Expected performance In this document, the performance of the mechanical splice is given with identical fibres only as specified in Annex A. Losses associated with tolerances in fibre cladding diameter and mode field mismatch are not taken into account. The measured attenuation is a function of the core concentricity, cladding non-circularity and alignment capability. The optical return loss performance is a function of the index matching gel and the fibre end face preparation. 1.4 Operating environment The tests selected combined with the severities and durations are representative of an outdoor enclosed environment defined as category OP in EN IEC 61753 1. To ensure that the product can be used in outdoor closures, boxes or street cabinets for categories A, G or S (as defined in EN IEC 61753 1) the specified lower temperature is extended to −40 °C and a water immersion requirement for temporary flooding conditions has been added. 1.5 Reliability Whilst the anticipated service life expectancy of the product in this environment is at least 20 years, compliance with this document does not guarantee the reliability of the product. This is expected to be predicted using a recognized reliability assessment programme. 1.6 Quality assurance Compliance with this document does not guarantee the manufacturing consistency of the product. This is expected to be maintained using a recognized quality assurance programme.
