IEC 61000-3-2:2018+A1:2020 deals with the limitation of harmonic currents injected into the public supply system. It specifies limits of harmonic components of the input current which can be produced by equipment tested under specified conditions. It is applicable to electrical and electronic equipment having a rated input current up to and including 16 A per phase, and intended to be connected…

IEC 60947-4-3:2020 applies to semiconductor controllers and semiconductor contactors for non-motor load intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V AC. It covers their use: – for operations of changing the state of AC electric circuits between the ON-state and the OFF-state; – with or without bypass switching devices; – as controller, for reducing…

IEC 62541-6:2020 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 62541-6:2020 specifies the OPC Unified Architecture (OPC UA) mapping between the security model described in IEC TR…

IEC 62541-6:2020 specifies the OPC Unified Architecture (OPC UA) mapping between the security model described in IEC TR 62541-2, the abstract service definitions specified in IEC 62541-4, the data structures defined in IEC 62541-5 and the physical network protocols that can be used to implement the OPC UA specification. This third edition cancels and replaces the second edition published in 2015…

IEC 62885-4:2020 is applicable to measurements of the performance of cordless dry vacuum cleaners for household use or under conditions similar to those in households. The results obtained under this document are intended to be comparable to the results obtained under IEC 62885-2 for mains-connected vacuums. The purpose of this document is to specify essential performance characteristics of…

This document specifies dimensional characteristics, contact allocation, tests and requirements of 7-pole connectors for electrical connections of electronically monitored charging systems of towing and towed vehicles. The electronic monitoring system is designed to detect 12 V and 24 V nominal supply voltage and to limit the current to 50 A, and this is a connector without any braking capacity.…

1 Scope This part of ISO/IEC 14543 enables a media connection, resource sharing and co-operation among computers, home appliances and consumer electronics using remote access (RA). Also, users and devices can share and control media resources. This document specifies: • an IGRS remote media access profile based on the IGRS RA core protocol and the IGRS RA platform protocol, and •…

1 Scope This document specifies the abstract class of a media thing (MThing), which is a basic component to construct Internet of media things. The MThing class contains the basic APIs to: — discover other MThing(s) in the network; — connect/disconnect MThing(s); — support transactions (e.g. payments) using media tokens between MThings.

1 Scope This part of ISO/IEC 11801, which is a Technical Report, provides definitions for, and examples of, direct attach cabling configurations. This document provides performance specifications for Classes D, E, EA, F, FA, I and II direct attach cabling by reference to ISO/IEC 11801-1. Informative limits for Class I direct attach cabling to support 5 m short reach mode application…

alarms intended for protection in non-residential or ordinary (nonhazardous) areas. 1.2 Carbon monoxide alarms covered by these requirements are intended to respond to the presence of carbon monoxide from sources such as, but not limited to, exhaust from internal-combustion engines, abnormal operation of fuel-fired appliances, and fireplaces. Carbon monoxide alarms are intended to alarm at…
