Surface cleaning appliances - Part 4: Cordless dry vacuum cleaners for household or similar use - Me...
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…
IEC 62541-4:2020 defines the OPC Unified Architecture (OPC UA) Services. The Services defined are the collection of abstract Remote Procedure Calls (RPC) that are implemented by OPC UA Servers and called by OPC UA Clients. All interactions between OPC UA Clients and Servers occur via these Services. The defined Services are considered abstract because no particular RPC mechanism for…
Smart cities - City service continuity against disasters - The role of the electrical supply
IEC 63152:2020 establishes concepts and gives guidelines to help sustain a variety of city services on the occasion of a disaster from the perspective of providing electricity. It outlines the basic concepts on how multiple city services can cooperate and continue by electricity continuity plan(s) and electricity continuity system(s). It also specifies methods and means to establish these.
The…
OPC Unified Architecture - Part 5: Information Model
IEC 62541-5:2020 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.

OPC Unified Architecture - Part 5: Information Model
IEC 62541-5:2020 defines the Information Model of the OPC Unified Architecture. The Information Model describes standardized Nodes of a Server’s AddressSpace. These Nodes are standardized types as well as standardized instances used for diagnostics or as entry points to server-specific Nodes. Thus, the Information Model defines the AddressSpace of an empty OPC UA Server. However, it is not…

This document supports the energy-saving design methodology according to ISO 14955‑1 and the methods for measuring energy supplied to machine tools and machine tool components defined in ISO 14955‑2. This document addresses the environmental evaluation of machine tools during the use stage based on reference scenarios. It contains an example for metal cutting machine tools.
This document defines…
Nanomanufacturing - Key control characteristics - Part 6-1: Graphene-based material - Volume resisti...
IEC TS 62607-6-1:2020 establishes a standardized method to determine the electrical key control characteristic
– volume resistivity
for powder consisting of graphene-based material like flakes of graphene, few layer graphene and/or reduced graphene oxide after preparation of a sample in pellet form by
– four probe method
using powder resistivity measurement system.
The volume resistivity is…

IEC 60068-3-7:2020 specifies a uniform and reproducible method of confirming that temperature test chambers conform to the requirements specified in the climatic test procedures of IEC 60068-2-1 and IEC 60068-2-2, when loaded with either heat-dissipating or non heat-dissipating specimens under conditions which take into account air circulation inside the working space of the chamber. This…
