Manufacturers of bar code equipment and users of bar code technology require publicly available standard symbology specifications to which they can refer when developing equipment and software. ISO/IEC 15420:2009 specifies the requirements for the bar code symbology known as EAN/UPC. It specifies EAN/UPC symbology characteristics, data character encodation, dimensions, tolerances, decoding…

IEC/PAS 61753-1-3:2009(E) is a Publicly Available Specification (PAS) that defines the minimum initial performance, test and measurement requirements and severities which a single-mode connector or cable assembly must satisfy in order to be categorized as meeting IEC Category I (industrial environment). Category I is an addition to environmental categories C, U, O, E described in IEC 61753-1 and…

This National Standard of Canada is equivalent to International Standard ISO/IEC 11770-3:2008. 1 Scope This part of ISO/IEC 11770 defines key management mechanisms based on asymmetric cryptographic techniques. It specifically addresses the use of asymmetric techniques to achieve the following goals. 1) Establish a shared secret key for a symmetric cryptographic technique between two entities A…

IEC 60364-5-56:2009 covers general requirements for safety services, selection and erection of electrical supply systems for safety services and electrical safety sources. Standby electrical supply systems are outside the scope of this part. This part does not apply to installations in hazardous areas (BE3), for which requirements are given in IEC 60079-14. This second edition of IEC 60364-5-56…

IEC 61987-10:2009 provides a method of standardizing the descriptions of process control devices, instrumentation and auxiliary equipment as well as their operating environments and operating requirements (for example, measuring point specification data). The aims of this standard are:<br /> - to define a common language for customers and suppliers through the publication of Lists of…

IEC 60079-18:2009 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 60079-18:2009 gives the specific requirements for the construction, testing and marking of electrical equipment…

IEC 60050-617:2009 has been published as a consequence of deregulation of the electricity market, it appeared necessary to establish a common glossary with those terms defining actors in the market, interface between actors and the technical or financial terms having a specific meaning in the context of electricity market. This horizontal standard IEC 60050-617:2009 is primarily intended for use…

Aztec Code is a two-dimensional matrix symbology whose symbols are nominally square, made up of square modules on a square grid, with a square bullseye pattern at their centre. Aztec Code symbols can encode from small to large amounts of data with user-selected percentages of error correction. Manufacturers of bar code equipment and users of the technology require publicly available standard…
