ISO/IEC/JTC 1 - ISO/IEC Joint Technical Committee for Information Technology

1.1 Scope This European Standard specifies requirements for the following aspects of information technology cabling: a) planning; b) installation practice. This European Standard is applicable to all types of information technology cabling inside buildings (and may be applied to cabling that is defined as part of the building) including generic cabling systems designed in accordance with the EN 50173 series. The requirements of Clauses 4, 5 and 6 of this standard are premises-independent unless amended by the requirements of premises-specific clauses. This European Standard: 1) details the considerations for satisfactory installation and operation of information technology cabling; 2) describes the methodology for the assessment of spaces, pathways (and pathway systems) and cabling (either installed or planned) in support of remote powering objectives; 3) excludes specific requirements applicable to other cabling systems (e.g. power supply cabling); however, it takes account of the effects other cabling systems have on the installation of information technology cabling (and vice versa) and gives general advice; 4) excludes those aspects of installation associated with the transmission of signals in free space between transmitters, receivers or their associated antenna systems (e.g. wireless, radio, microwave or satellite). This European Standard is intended for application within commercial and residential premises. This standard is applicable to certain hazardous environments. It does not exclude additional requirements which are applicable in particular circumstances, defined by e.g. electricity supply and electrified railways. 1.2 Conformance For a cabling installation to conform to this European Standard: a) the planning of the installation shall meet the requirements of Clause 4; b) the installation practices shall meet the requirements of Clause 5; c) the additional requirements of the applicable premises-specific clause shall be met; d) the bonding system within the premises shall be in accordance with EN 50310; e) where a lightning protection system is required, it shall conform to the “integrated lightning protection system" according to EN 62305-4; f) other lightning protection systems, including the “isolated lightning protection system” according to EN 62305-3 are allowed provided that specific restrictions are applied both to the implementation of the information technology cabling and the requirements of EN 50310 as agreed between the planners of the lightning protection system and the information technology cabling; g) local regulations shall be met. The responsibilities for specific elements of conformance may be made by national-specific amendment of Annex B.

This European Standard specifies the additional specific HBES requirements for the common rules for the planning and the installation of HBES home cabling systems. The structure is in accordance with EN 50174 2. This European Standard focuses on requirements for HBES cabling systems in homes. Requirements for backbones cabling in buildings are also considered. HBES radio frequency (RF) systems are considered as extensions to cabled systems. RF connections may have an impact on the infrastructure. Different infrastructure models are presented for the use of RF connections instead of wired ones (e.g. fewer installation spaces IS6). Optical fibre HBES installation guidelines may be considered in future. Power line systems are outside the scope of this European Standard.

This European Standard specifies the optical fibre access network cabling within multi-subscriber premises (which may comprise single or multiple buildings) and intended to support deployment of optical broadband networks. The cabling within the subscriber space for onward distribution of services beyond the customer premises equipment is not specified. Cabling defined by this standard supports a wide range of broadband applications delivering services including voice, data, text, image and video. This European Standard specifies: a) the structure and configuration of the optical fibre cabling; b) cabling performance requirements; c) implementation options. Safety (electrical safety, optical safety and protection, fire, etc.) and electromagnetic compatibility (EMC) requirements are outside the scope of this European Standard and are covered by other standards and regulations. However, information given in this European Standard may be of assistance in meeting these standards and regulations.

This European Standard specifies requirements and provides recommendations for the following aspects of information technology cabling: a) planning; b) installation practice. This European Standard is applicable to all types of information technology cabling outside buildings including generic cabling systems designed in accordance with EN 50173 series. The requirements and recommendations of this European Standard may be applied to cabling that is defined as part of the building. The requirements and recommendations of Clauses 4, 5 and 6 of this European Standard are subject to any site-specific requirements and recommendations of Clause 7. The planning of the pathway systems, spaces and structures within the core and access network cabling as described in Figure 2 that are owned by access providers is excluded except for requirements and recommendations that provide basic safety, function and environmental objectives for mechanical, ingress and climatic characteristics (i.e. excluding pathway dimensions, distribution of spaces and similar constraints based on specific transmission methods). The installation practices applicable to all cabling installation methods are included by the provision of the necessary planning requirements and recommendations associated with each one with the exception of information technology cabling installed: – around or within aerial power supply or associated earth conductors; – on infrastructures carrying power supplies in excess of AC/DC 25 kV. This European Standard: 1) details the considerations for satisfactory installation and operation of information technology cabling; 2) excludes specific requirements applicable to other cabling systems (e.g. power supply cabling); however, it takes account of the effects other cabling systems may have on the installation of information technology cabling (and vice versa) and gives general advice; 3) excludes those aspects of installation associated with the transmission of signals in free space between transmitters, receivers or their associated antenna systems (e.g. wireless, radio, microwave or satellite). This European Standard is applicable to certain hazardous environments. It does not exclude additional requirements which are applicable in particular circumstances, defined by e.g. electricity supply and electrified railways. The requirements within this European Standard do not cover any additional requirements for the information technology cables installed in hazardous or stressful environments e.g. electricity supply and electric railway locations (see Clause 7).

This European Standard sets the requirements for functional safety for HBES/BACS products and systems, a multi-application bus system where the functions are decentralised, distributed and linked through a common communication process. The requirements may also apply to the distributed functions of any equipment connected in a home or building control system if no specific functional safety standard exists for this equipment or system. The functional safety requirements of this European Standard apply together with the relevant product standard for the device if any. This European Standard is part of the EN 50491 series of standards. This European Standard does not provide functional safety requirements for safety-related systems.

This Technical Report establishes the general rules for assessing HBES installations, according to its complexity and energy performance. This Technical Report applies to – household HBES installation, from and up to the connection point with the utility (i.e. electricity, telecommunications, tele-service, water, gas, security and similar), – HBES installations that include applications related to automation and integrated control of electrical and/or electronic devices, – the networks used for the HBES interconnection regardless of the transmission media used for their communications, – new HBES installations, retrofitting and enlargement of existing installations.

This standard applies to electrical equipment using signals in the frequency range 3 kHz to 148,5 kHz to transmit information on low voltage electrical systems, either on the public electricity distribution network or within installations in consumers’ premises. It specifies the frequency bands allocated to the different applications, limits for the terminal output voltage in the operating band and limits for conducted and radiated disturbance. It also gives the methods of measurement. It does not specify the modulation methods, the coding methods or functional features (except those for the prevention of mutual interference). Environmental requirements and tests are not included. NOTE 1 Compliance with this standard does not imply permission to establish communication with locations outside the consumer’s installation or with other consumers through the public electricity distribution network where this would not otherwise be allowed. The object of the standard is to limit mutual influence between transmission equipment in electrical installations and between such equipment and other equipment. In addition this standard is intended to limit interference caused by signal transmission equipment to sensitive electronic equipment. However, complete freedom from such interference cannot be assured. NOTE 2 Designers should consider signalling systems in conformance with this standard when determining immunity for electrical equipment.

This European Standard concentrates on control applications for Home and Building HBES Open Communication System and covers any combination of electronic devices linked via a digital transmission network. Home and Building Electronic System as provided by the HBES Open Communication System is a specialized form of automated, decentralised and distributed process control, dedicated to the needs of home and building applications. The EN 50090 series concentrates on HBES Open Communication System Class 1 and includes a specification for a communication network for Home and Building for example for the control of lighting, heating, food preparation, washing, energy management, water control, fire alarms, blinds control, different forms of security control, etc. This European Standard gives an overview of the features of the HBES Open Communication System and provides the reader with references to the different parts of EN 50090 series. This European Standard is used as a product family standard. It is not intended to be used as a stand-alone standard.

IEC 62614:2010 describes the launch condition requirements used for measuring multimode attenuation in passive components and in installed cable plants. In this standard, the fibre types that are addressed include category A1a (50 m/125 m) and A1b (62,5 m/125 m) multimode fibres, as specified in IEC 60793-2-10. The nominal test wavelengths detailed are 850 nm and 1 300 nm. This standard may be suitable for multimode attenuation measurements for other multimode categories and/or other wavelengths, but the source condition for other categories and wavelengths are not defined here.

This Technical Report describes the current realisations of Twisted Pair 1 medium interface solutions. TP1 signal forms are not described in this technical report as they already form part of EN 50090-5-2.

This product family standard sets the minimum level of EMC performance for HBES/BACS products intended to be connected to an HBES/BACS system. A set of devices connected to perform a stand alone application is not considered to be an HBES/BACS system and therefore are outside the scope of this European Standard. This European Standard provides the general performance requirements and test setups for EMC for all products connected to HBES/BACS. This connection can be wired (e.g. communication cable, power line) or wireless (e.g. radiofrequency, infrared). This European Standard is applicable (but not limited) to – operator stations and other human system interface devices, – devices for management functions, – control devices, automation stations and application specific controllers, – field devices and their interfaces, – cabling and interconnection of devices, – dedicated devices for engineering and commissioning tools for HBES/BACS

The scope of EN 50491-5-1:2010 applies, with the following modification: Replace the 3rd paragraph with the following ones: This is the specific part of EN 50491-5 for HBES/BACS used in industry environment. The environment covered by this standard is industrial, according to the definition in EN 61000-6-2.

This European Standard provides the environmental conditions for all devices connected to HBES/BACS.

This Technical Report applies to electrical equipment using signals in the frequency range 1,6 MHz to 30 MHz to transmit information on low voltage electrical systems, either on the public supply system or within installations in consumers’ premises. It is a Technical Report covering the different standards for HF Power Line produced by SC205A. It points to related documents about: -frequency bands, coexistence and filters; -limits for the terminal output levels in the operating band; -limits for conducted and radiated disturbance (product & installation EMC); -measurement methods. It does not specify the signal modulation methods nor the coding methods nor functional features. Environmental requirements and tests are not included. The requirements have been selected so as to ensure an adequate level of EMC and EMI for all apparatus (e.g. including residential, commercial, light industrial and industrial premises). The severity levels required by this Technical Report may not cover extreme cases which may occur in any location but with a low probability of occurrence. In special cases situations will arise where the level of disturbances may exceed the levels specified in this Technical Report (e.g. where a hand-held transmitter is used in proximity to an apparatus). In these instances special mitigation measures may be required.

1.1 The SmartHouse and its components The SmartHouse consists of a large and wide ranging set of many Services, Applications, Equipment, Networks and Systems that act together in delivering the “intelligent” or “connected” home in order to address security and control, communications, leisure and comfort, environmental integration and accessibility. These components are represented by many actors that interact and work together to provide interoperable systems that benefit the home based user in the SmartHouse. Because of this wide ranging variability of the entities in the SmartHouse, there is a very high level of potential complexity in finding the optimal solution for any particular SmartHouse. The main actors that influence the SmartHouse are the consumers (customers, subscribers, individuals) that live in and utilise the Services, Applications and Products that are designed for the SmartHouse. It is therefore appropriate that the other main set of actors are the service and application providers that deliver the services that the consumers need and require, including those responsible for installing systems in the SmartHouse and for maintaining them. These consumers have needs and requirements in many areas and these are described in the Section on Consumers. Likewise the aims and objectives of the Service Providers in fulfilling consumer needs are described in the section on Service Providers. The installer also has to fulfil consumer needs and the Installation Process is described in the section on Installation.

This standard applies to electrical equipment using signals in the frequency range 1,6 MHz to 30 MHz to transmit information on low voltage electrical systems, either on the public supply system or within installations in consumers’ premises. It does not specify the signal modulation methods nor the coding methods nor functional features. Environmental requirements and tests are not included. The immunity requirements have been selected so as to ensure an adequate level of immunity for apparatus at residential, commercial and light industrial premises (Class 1 environment), and industrial premises supplied from a dedicated HV/MV or MV/LV transformers (Class 2 environment). The severity levels required by this standard may not cover extreme cases which may occur in any location but with a low probability of occurrence. In special cases situations will arise where the level of disturbances may exceed the levels specified in this standard (e.g. where a hand-held transmitter is used in proximity to an apparatus). In these instances special mitigation measures may be required.

This European product safety standard applies to the filter part of portable devices for household and similar uses (hereafter referred to as portable decoupling filters) consisting of the filter part, a plug or an appliance inlet or a provision for connection by terminals or with a non-rewirable cord and one (multiple) socket-outlet or an appliance outlet. They are intended for single-phase circuits for nominal currents not exceeding 16 A and for nominal voltages not exceeding 250 V a.c. to neutral operating in the frequency range 3 kHz to 148,5 kHz and from 1,6 MHz to 30 MHz. The filtering functions are described in EN 50065-4-1. This standard does not cover phase couplers. Portable decoupling filters shall not be used as part of the fixed installation, where EN 50065-4-2 applies. Plugs and socket-outlets connected to the filter part and plugs and socket-outlets integrated with the filter part shall comply with the relevant national standard(s). Appliance inlets and appliance outlets connected to the filter part shall comply with the relevant parts of the EN 60320 series. Appliance inlets and appliance outlets integrated with the filter parts are not covered by this standard. This standard can be used for portable mains communication devices when no other product standard exists. This standard can be used for other portable mains filters other than those described in EN 50065-4-1 when no other product standard exists. Filters including batteries are not covered by this standard.

This European Standard defines the mandatory and optional requirements for the medium specific physical and data link layer of power line Class 1 in its two variations PL110 and PL132. Data link layer interface and general definitions, which are medium independent, are given in EN 50090 4-1.

This European Standard applies to phase couplers in a mains communication system for phase to neutral voltage not exceeding 250 V a.c. and a nominal current not exceeding 125 A, intended for household and similar fixed installation including residential, commercial and light industrial buildings. This European Standard applies to phase couplers used to control the coupling of communication signals between phases or sections of a mains communication system. A “phase coupler” may be used to achieve coupling between the phases of a multiphase installation, or to provide bridging of signals around other system components. The standard defines  the requirements to ensure a minimum coupling between the sections, and  the requirements to ensure no change on the safety of the electrical installation.

This European Standard defines the mandatory and optional requirements for the medium specific physical and data link layer for HBES Class 1 Twisted Pair in its two variations called TP0 and TP1. Data link layer interface and general definitions, which are media independent, are given in EN 50090 4 2.

This international standard establishes general principles for network- and device-management shared by and independent of the installation mode. The goal is to standardize the interaction, between a management client and a management server, that shall lead to the successful configuration of the devices. In this way, these management procedures thus specify the highest level communication requirements between a management client and a management server. These requirements specify: a) the sequence of messages that shall be exchanged between a management client and a management server, and b) the contents and interpretation of the transported data, and c) the action to take based on these data (setting internal resources, state machines, physical actions, …), and d) the error and exception handling. The management procedures base on the application layer services. Some management procedures solely base on the use of one or a sequence of dedicated application layer services to achieve the required goal. For these, the documents EN 50090-4-1 and EN 50090-4-2 provide sufficient information for the underlying mechanisms. Other management procedures additionally use the application layer services to access internal data in the management server to achieve the required goal. These data are laid down as objects as specified in EN 50090 3 2.

This part of the EN 50090 specifies the services and protocol in a physical layer independent way for the data link layer and for the network layer and the transport layer for usage in Home and Building Electronic Systems

This part of EN 50090 specifies the structure and functioning of servers for the objects which form the interface between the application layer and the application and management.

This part of the EN 50090 specifies the services and protocol of the application layer for usage in Home and Building Electronic Systems. It provides the services and the interface to the user process as defined in EN 50090 3 2. This procedure is based on the services and the protocol is provided by the Transport Layer, Network Layer and Data Link Layer as specified in EN 50090 4 2.

This standard applies to segmentation filters in a mains communication system used for single or multiphase installations having a phase to neutral voltage not exceeding 250 V a.c. and a nominal current not exceeding 125 A, intended for household and similar fixed installation including residential, commercial and light industrial buildings and utility networks. These filters (see Figure 1) are used to control the coupling of signals between two areas of a mains communication system. The standard defines -the minimum impedance in the relevant frequency range(s) at both ports, -the minimum attenuation of signals transmitted between port.

This standard applies to impedance filters in a mains communication system for phase to neutral voltage not exceeding 250 V a.c. and a nominal current not exceeding 125 A, intended for household and similar fixed installation including residential, commercial and light industrial buildings. This standard also applies to "plug-in filters". These filters (see Figure 1) are used to set a suitable impedance, in the nominal frequency range of the mains signalling system, at any point of the low voltage mains network where a low impedance equipment is connected, in order to allow reliable operation of mains signalling system. These impedance filters can be used either in utility or consumer networks. They may also be used in conjunction with incoming filters and segmentation filters.

This standard applies to electrical equipment using signals in the frequency range 95 kHz to 148,5 kHz to transmit or receive information on low voltage electrical systems, residential, commercial and light industrial environments. In the case of equipment which includes functions other than the transmission or reception of information on low voltage electrical supplies, this standard applies only to that part of the equipment intended for such transmission or reception of information. Other parts of the equipment shall comply with the immunity standard or standards relevant to the functions of those other parts. In the event of tests being specified in those other standards of a different severity and where the construction of the equipment is such that the functions cannot be tested separately, the higher severity shall apply to all affected functions. The object of this standard is to limit mutual influence between mains communication equipment and systems (MCES) operating in different frequency bands as defined in EN 50065-1 and to contribute to ensuring Electromagnetic Compatibility in general. It specifies essential immunity requirements and test methods, including those tests which are to be performed during type-testing of MCES on low-voltage installations, for electromagnetic interference in general and more specific interference coming from other MCES. It therefore defines the immunity test requirements for apparatus in relation to continuous and transient disturbances, both conducted and radiated, and electrostatic discharges. Test requirements are specified for each port considered. This standard gives limits which are applicable to products operating in residential, commercial and light industrial environments. The levels do not however cover extreme cases which may occur in any location but with a low probability of occurrence. In special cases situations will arise where the level of disturbances may exceed the levels specified in this standard e.g. where a hand-held transmitter is used in proximity to an apparatus. In these instances special mitigation measures may have to be employed. It does not specify immunity between mains communication systems operating in the same band (as defined in EN 50065-1) or immunity to signals originating from Power Line Carrier systems operating on high or medium voltage networks. Safety considerations are not included in this standard.

This standard applies to incoming filters used to control the coupling of signals between the utility area and the consumer area (see Figure 1). The standard defines • the minimum impedance in the relevant frequency band(s) at both Utility port and Consumer port, • the minimum attenuation of unwanted signals transmitted from the utility side to the consumer side and vice versa, • the transmission characteristics: - operating frequency domain for both utility side and consumer side, - attenuation between the utility side and the consumer side and vice versa, - impedance at the utility side and at the consumer side. This standard applies to incoming filters designed for and used in single or multiphase installations.

Other parts of the equipment shall comply with the immunity standard or standards relevant to the functions of those other parts. In the event of tests being specified in those other standards of a different severity and where the construction of the equipment is such that the functions cannot be tested separately, the higher severity shall apply to all affected functions.

It therefore defines the immunity test requirements for apparatus in relation to continuous and transient disturbances, both conducted and radiated, and electrostatic discharges. Test requirements are specified for each port considered. This standard gives limits which are applicable to products operating in the public supply network, operated by electricity utilities. The levels do not however cover extreme cases which may occur in any location but with a low probability of occurrence.
