IEC 62439-3:2012 specifies two redundancy protocols designed to provide seamless recovery in case of single failure of an inter-bridge link or bridge in the network, which are based on the same scheme: duplication of the LAN, resp. duplication of the transmitted information. This second edition cancels and replaces the first edition published in 2010. It constitutes a technical revision. The main…

IEC 61000-4-4:2012 is available as IEC 61000-4-4:2012 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61000-4-4:2012 relates to the immunity of electrical and electronic equipment to repetitive electrical fast transients. It has the status of a basic EMC publication in accordance with IEC…

IEC 61000-4-4:2012 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61000-4-4:2012 relates to the immunity of electrical and electronic equipment to repetitive electrical fast…

IEC 60695-7-3:2011 concerns laboratory tests used to measure the toxic components of the fire effluent from either electrotechnical products or materials used in electrotechnical products. It provides guidance on the use and interpretation of results from such tests. It discusses currently available approaches to toxic hazard assessment consistent with the approach of ISO TC 92 SC 3, as set out…

IEC 61290-4-2:2011 applies to optical amplifiers (OAs) and optically amplified elementary sub-systems. More specifically, it applies to OAs using active fibres (optical fibre amplifiers, OFAs) containing rare-earth dopants, such as erbium doped fibre amplifiers (EDFAs), presently commercially available, as indicated in IEC 61291-1. The object of this part of IEC 61290-4 is to establish uniform…

IEC/PAS 62565-2-1:2011(E) establishes a blank detail specification for the essential electrical properties and certain other common characteristics including dimensional, structural and mechanical properties of single-wall carbon nanotubes. It provides a standardized format for detail specifications characterising essential basic properties of single-wall nanotubes and recommends measurement…

ISO/IEC 24775:2011(E) defines an interface for the secure, extensible, and interoperable management of a distributed and heterogeneous storage system. This interface uses an object-oriented, XML-based, messagingbased protocol designed to support the specific requirements of managing devices and subsystems in this storage environment. Using this protocol, this International Standard describes the…

IEC 61169-19:2011 is a sectional specification. It provides information and rules for preparation of detail specification of SSMB series R.F connectors together with the pro forma blank detail specification The SSMB series connectors with characteristic impedance 50 ohm are one kind of low power miniature connectors with snap-on coupling mechanism and have the characteristics of light weight,…

Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body…
