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…

IEC 63171-4:2022 covers shielded and unshielded free and fixed multimedia connectors (MMC) for data transmission with frequencies up to and above 3 000 MHz for shielded and up to 600 MHz for unshielded connectors, both with current-carrying capacity with up to 8 ways. It specifies the common dimensions, mechanical, electrical and transmission characteristics and environmental requirements as well…

IEC 62764-1:2022 specifies a methodology for determining the exposure to multiple magnetic field sources for passenger cars and light commercial vehicles including standardized operating conditions and measurement volumes and/or surfaces. This part of IEC 62764 applies to the assessment of human exposure to low-frequency magnetic fields generated by automotive vehicles. For plug-in vehicles, this…

IEC 63171-5:2022 refers to International Standards for test and measurement, environmental testing as well as solderless connections. This part of IEC 63171 describes 2-way shielded or unshielded circular connectors with IP65/IP67 M8 or M12 locking, typically used for balanced single-pair data transmission with frequencies up to 600 MHz and with current-carrying capacity up to 4 A, for use in…
