IEC 62271-107:2019 applies to three-pole-operated fused circuit-switchers designed with rated voltages above 1 kV up to and including 52 kV for use on three-phase alternating current systems of either 50 Hz or 60 Hz. This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical…

This Recommendation | International Standard specifies the system layer of the coding. It was developed principally to support the combination of the video and audio coding methods defined in Parts 2 and 3 of ISO/IEC 13818. The system layer supports six basic functions: 1) the synchronization of multiple compressed streams on decoding; 2) the interleaving of multiple compressed streams into…

This document specifies the use of the integrated resources necessary for the scope and information requirements for the representation of engineering property data that are used for product design, product validation and other purposes. NOTE 1 The application activity model in Annex F provides a graphical representation of the processes and information flows that are the basis for the…

IEC 60839-7-8:2019 specifies a protocol for point-to-point transmission of alarms and faults, as well as communications monitoring, between a supervised premises transceiver and a receiving centre transceiver using the Internet protocol (IP). The protocol is intended for use over any network that supports the transmission of IP data. These include Ethernet, xDSL, GPRS, WiFi, UMTS and WIMAX. The…

IEC 60793-2-10:2019 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 60793-2-10:2019 is applicable to optical fibre sub-categories A1-OM1, A1-OM2, A1-OM3, A1-OM4, A1-OM5, and A1d…

IEC 60793-2-10:2019 is applicable to optical fibre sub-categories A1-OM1, A1-OM2, A1-OM3, A1-OM4, A1-OM5, and A1d. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables. Sub-categories A1-OM2, A1-OM3, A1-OM4 and A1-OM5 apply to 50/125 µm graded index fibre in four bandwidth grades. Each of these bandwidth grades is defined for two levels of…

This document specifies elements of conformance testing methodology, test assertions, and test procedures as applicable to two-dimensional face images defined in the ISO/IEC 19794-5:2005 biometric data interchange format standard for face image data. This document establishes — test assertions of the structure of the face image data format as specified in ISO/IEC 19794-5:2005 (Type A…
