CISPR 22:2008 applies to information technology equipment (ITE). Procedures are given for the measurement of the levels of spurious signals generated by the ITE and limits are specified for the frequency range 9 kHz to 400 GHz for both class A and class B equipment. No measurements need be performed at frequencies where no limits are specified. The intention of this publication is to establish uniform requirements for the radio disturbance level of the equipment contained in the scope, to fix limits of disturbance, to describe methods of measurement and to standardize operating conditions and interpretation of results. This sixth edition of CISPR 22 cancels and replaces the fifth edition published in 2005, its Amendment 1 (2005) and Amendment 2 (2006). This edition constitutes a minor revision. NEW! CISPR 22:2008 is also available as IEC Standards+ CISPR 22:2008 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

This standard gives guidance on writing the technical specifications for the procurement of wind turbines for use in electrity generating stations (wind power stations. Other possible applications of such equipment have not been considered in the preparation of this guide. This Guide covers wind turbine generator systems (WTGS) with swept area equal to or larger than 40 m2. This guide for procurement of wind turbines has been prepared to be used with the existing international standard IEC 1400-1, it should therefore be read in addition and complementary to the International standard.

The present document specifies the functional accessibility requirements applicable to ICT products and services, together with a description of the test procedures and evaluation methodology for each accessibility requirement in a form that is suitable for use in public procurement within Europe. The present document might be useful for other purposes such as procurement in the private sector. The present document is intended to be used as the basis for an accessible ICT procurement toolkit. The present document will primarily be useful for public procurers to identify the requirements for their purchases, and also for manufacturers to employ it within their design, build and quality control procedures. The present document contains the necessary functional requirements and provides a reference document such that if procedures are followed by different actors, the results of testing are similar and the interpretation of those results is clear. The test descriptions and evaluation methodology included in the present document are elaborated to a level of detail compliant with ISO/IEC 17007:2009 [i.14], so that conformance testing can give conclusive results. The inherent nature of certain situations makes it impossible to make reliable and definitive statements that accessibility requirements have been met. In those situations therefore, the requirements in the present document are not applicable: - when the product is in a failure, repair or maintenance state where the ordinary set of input or output functions are not available; - during those parts of start-up, shutdown, and other state transitions that can be completed without user interaction. NOTE 1: Even in the above situations, it is best practice to apply requirements in the present document wherever it is feasible and safe to do so. NOTE 2: Compliance issues are covered in normative clause C.1.

This European Standard deals with procedures for the assessment of electricity generation within the direct building environment through wind power systems. The wind power systems described in this document are small plants as they may occur in domestic production and use of electricity in connection with buildings. This standard covers wind generation power systems ≤ 75 kW.

EN 14908 standard consists of 6 parts. It adopts the LonTalk protocol. LonTalk is a protocol optimized for control. Originally developed by Echelon Corporation for networking devices over media such as twisted pair, powerlines, fiber optics, and RF. It is popular for the automation of various functions in industrial control, home automation, transportation, and buildings systems such as lighting and HVAC. The protocol has been adopted as a family of standards by CEN (EN 14908), as well as by ISO/IEC (ISO/IEC 14908). This standard specifies a multi-purpose control network protocol stack optimized for smart grid, smart building, and smart city applications.

EN 13757-5 Communication systems for meters - Part 5: Wireless M-Bus relaying - This European Standard specifies the protocols to use when performing relaying in wireless meter readout networks. This European Standard is an extension to wireless meter readout specified in EN 13757-4. It supports the routing of modes P and Q, and simple single-hop repeating of modes S, T, C, F and N. The main use of this standard is to support simple retransmission as well as routed wireless networks for the readout of meters. NOTE Electricity meters are not covered by this standard, as the standardisation of remote readout of electricity meters is a task for IEC/CENELEC.

EN 13757-4 Communication systems for meters and remote reading of meters - Part 4: Wireless meter readout (Radio meter reading for operation in SRD bands) - This European Standard specifies the requirements of parameters for the physical and the link layer for systems using radio to read remote meters. The primary focus is to use the Short Range Device (SRD) unlicensed telemetry bands. The standard encompasses systems for walk-by, drive-by and fixed installations. As a broad definition, this European Standard can be applied to various application layers.

EN 13757-2 Communication systems for and remote reading of meters - Part 2: Physical and link layer - This European Standard covers the physical and link layer parameters of baseband communication over twisted pair (M Bus) for meter communication systems. It is especially applicable to heat meters, heat cost allocators, water meters and gas meters. NOTE It is usable also for other meters (like electricity meters) and for sensors and actuators. For generic descriptions concerning communication systems for meters and remote reading of meters see EN 13757-1.

This document specifies data exchange and communications for meters in a generic way. This document establishes a protocol specification for the Application Layer for meters and establishes several protocols for meter communications which can be applied depending on the application being fulfilled. This document also specifies the overall structure of the Object Identification System (OBIS) and the mapping of all commonly used data items in metering equipment to their identification codes. NOTE Electricity meters are not covered by this document, as the standardization of remote readout of electricity meters is a task for CENELEC/IEC.
