This document specifies the grades and quality, the dimensional characteristics, the dimensional and geometrical tolerances, and the surface finish of standardized guide rails and their fishplates. In addition, this document defines a designation system for guide rails. This document is applicable to guide rails used in passenger lift and service lift installations to provide guiding for the car…

1 Scope This document defines the air interface for radio frequency identification (RFID) devices operating in the 860 MHz to 960 MHz industrial, scientific, and medical (ISM) band used in item management applications. It provides a common technical specification for RFID devices that can be used to develop RFID application standards. This document is intended to allow for compatibility and to…

1 Scope This part of IEC 60079 specifies requirements for construction, testing and marking for Ex Equipment that contains parts of the equipment with different Equipment Protection Levels (EPLs) and a separation element. This equipment is mounted across a boundary where different EPLs are required, for example between different gas hazardous areas, dust hazardous areas or gas hazardous…

1 Scope 1.1 Application This Standard specifies a test method for three-phase induction motors rated 0.746 kW and higher. The Standard also references energy efficiency levels for three-phase induction motors rated 0.746 kW up to 400 kW. This Standard references energy efficiency levels for both NEMA and IEC motor designations. Efficiency requirements for units rated for operation at 60 Hz are…

1 Scope 1.1 Inclusions This Standard specifies the test methods to be used in measuring the energy efficiency of small direct- current (dc), and single- and small three-phase alternating-current (ac) motors. It includes the following motor types: a) capacitor, permanent-split; b) capacitor, capacitor-start or capacitor-run; c) split phase; d) split phase start, capacitor-run; e)…

This document specifies the representation of latitude and longitude and optionally height or depth compatible with previous editions of ISO 6709. This document also supports the representations of other coordinate types and time that can be associated with those coordinates as defined through one or more coordinate reference systems (CRS). This document describes a text string of coordinates,…

IEC 61196-4:2022 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61196-4:2022 edition 4.0 and the previous IEC 61196-4:2015 edition 3.0. Furthermore, comments from IEC SC 46A experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the…

IEC 61196-4:2022 applies to radiating coaxial communication cables, and specifies the terms and definitions, material and construction, IEC type designation, standard rating and characteristics, identification, marking and labelling, requirements of finished cables, quality assessment, delivery and storage, etc. This fourth edition cancels and replaces the third edition published in 2015 This…

This document defines the terms and definitions related to truck platooning systems (TPS), and the mode transitions in the platooning control system (PCS). The PCS is comprised of two main functions: the platooning operation control function (POCF) and the platooning manoeuvre control function (PMCF). This document specifies: —    POCF and PMCF governing how vehicles join and leave platoons…

Field devices are a key component in intelligent transport systems (ITS). Field devices include traffic signals, message signs, weather stations, traffic sensors, roadside equipment for connected ITS (C-ITS) environments, etc. Field devices often need to exchange information with other external entities (managers). Field devices can be quite complex, necessitating the standardization of many data…
