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.

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 13321-1 Open data communication in building automation, controls and building management - Home and building electronic system - Part 1: Product and system requirements - This European Standard specifies, as for Home or Building Electronic Systems (HBES) for the domain of Building Automation and Control System Application and Building Management (BACS), common rules for a class of multi-application bus systems where the functions are decentralised and linked through a common communication process. This European Standard sets the basic requirements for products and systems. The requirements may also apply to the distributed functions of any equipment connected in a home or building control system if no specific standard exists for this equipment or system. Due to its reference to the EN 50090 series, this European Standard sets requirements for the BACS area in relation to Architecture and Hardware and Application and Communication of systems based on HBES amongst other areas, and specifies the basic requirements for interoperability (between products and systems). Aspects such as environmental conditions/external influences, electrical safety, EMC, etc. also used to be covered by EN 50090-2-2, which will be superseded by the now available EN 50491 series. The latter European Standards series was jointly developed by CENELEC/TC 205 and CEN/TC 247 and will in the future also include aspects like functional safety in normal use (now contained in the EN 50090-2-3). The EN 50491 series applies, together with the relevant product standard for devices, if applicable.
