IEC 61936-2:2023 provides, in a convenient form, requirements for the design and the erection of DC installations in systems with nominal voltages above 1,5 kV DC, so as to provide safety and proper functioning for the use intended. For the purpose of interpreting this document, a DC installation is considered to be one of the following: a) A converter station or DC switching station; b) one (…

The objective of this document is to provide guidance on the use of ISO 5167:2022 series. ISO 5167:2022 is an International Standard for flow measurement based on the differential pressure generated by a constriction introduced into a circular conduit (see ISO 5167-1:2022, 5.1). It presents a set of rules and requirements based on theory and experimental work undertaken in the field of flow…

1 Scope 1.1 This Standard applies to industrial electrical machinery comprising interconnected mechanical, electrical, or electronic equipment, including industrial robots and industrial robotic equipment operating in a co-ordinated manner. Notes: 1) Examples of industrial electrical machinery covered by this Standard include handling and assembly machines, machines for packaging, factory…

IEC SRD 63273-1:2023 series aims to scope out the requirements of city information modelling standards by collecting and analysing its use cases. Specifically, the IEC SRD 63273 series achieves the objectives of identifying the key application areas and stakeholders, developing user stories and clarifying the relationship among these stakeholders, collecting and analysing use cases of city…

This standard applies to precast reinforced concrete sewer maintenance holes, catch basins, valve chambers and pumping stations intended for use to a maximum depth of 7 m in sanitary sewer systems, combined sewer systems, storm sewer and drinking water systems. NOTE — Even if they are not mentioned in the scope of this standard, certain elements described in this standard may be used in water…

1 Scope 1.1 General This Standard is designed to be used with related occupational or technical standards. It is intended to be referenced by other standards as the primary set of requirements for health and safety management of work in confined spaces. This Standard is designed for voluntary application in Canadian workplaces. However, the principles established in this Standard are based on…

This document specifies the standards for design, construction and maintenance following completion of intervention to be applied for performing intervention work using cementitious materials to improve the performance of existing concrete structures. The intervention dealt with in this document is intended to restore, sustain or improve the mechanical performance of concrete structures. When the…
