IEC TR 61850-7-5:2021, which is a technical report, establishes modelling concepts that help the user to understand how to apply the models defined in IEC 61850-7-4 and IEC 61850-7-3 to implement practical applications. This document provides the basic concepts that are valid for all application domains using IEC 61850. Domain specific concepts are defined in other technical reports as in the…

This document specifies requirements for two types of reinforced hoses and hose assemblies of nominal size from 3,2 to 25, dependent on relation of minimum burst pressure to maximum working pressure. Each type is divided into classes dependent on maximum working pressure. They are suitable for use with: —    oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743-4 at temperatures…

IEC 61243-1:2021 is applicable to portable voltage detectors, with or without built-in power sources, to be used on electrical systems for voltages of 1 kV to 800 kV AC, and frequencies of 50 Hz and/or 60 Hz. This document applies only to voltage detectors of capacitive type used in contact with the bare part to be tested, as a complete device including its insulating element or as a separate…

This document describes criteria and procedures for acoustic classification of dwellings. The purpose of this document is to make it easier for developers to specify a classified level of acoustic quality for a dwelling, and help users and builders to be informed about the acoustic conditions and define increased acoustic quality. The document can also be applied as a general tool to characterize…

This document provides guidelines for suppliers to show in which part of the Sustainable Development Goals fine bubble technologies can contribute to users. This document also provides guidelines for document writers to assess the contribution of their documents related to fine bubble technology to the Sustainable Development Goals. It also enables users to understand the benefits of using fine…

Variable message signs (VMSs) are installed in areas where traffic managers identify a frequent need to convey information to the travelling public, such as upstream from interchanges to alert the public to downstream congestion in time for them to alter their routes. This allows traffic managers to improve the efficiency, safety, and quality of traveller journeys. In order to manage the…

This document enables the advancement of interoperability from the data/information exchange paradigm to knowledge sharing at decreasing level of abstraction, starting at IT concept level (semantic coordination) through business domain concept level (agreed service function level cooperation), domain level (cross-domain cooperation) up to individual context (skills-based end-user collaboration).…

1 Scope 1.1 Inclusions This Standard specifies requirements for management of impairment in the workplace while providing specific requirements and guidance for impairment due to substance use, following occupational health and safety management system (OHSMS) principles, as they apply to a) development of a management of impairment in the workplace policy; b) management commitment and…
