IEC 61558-2-23:2024 deals with the safety of transformers for construction sites and power supply units incorporating transformers for construction sites. Transformers incorporating electronic circuits are also covered by this document. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following…

Scope 1.1 This Standard specifies the physical property requirements and test methods to determine the material properties for light density, open cell spray applied semi-rigid polyurethane foam, used as a thermal insulation for building applications, whether applied on a building site or in a prefabrication (manufacturing) facility. 1.2 The spray polyurethane foam system installer site…

IEC 62676-2-11:2024 defines minimum requirement profiles for Video Management Systems (VMS) and cloud Video-Surveillance-as-a-Service (VSaaS) Systems to optimize interfacing with third parties. It defines minimum required VMS interoperability levels from video export to exclusive video control, for the sake of remote support, for example in crisis situations, regulating governmental…

Scope 1.1 Facilities and worksites affected This Standard identifies the requirements for a PSM system for facilities and worksites handling or storing materials that are potentially hazardous either due to an inherent chemical, biological, toxicological, or physical property of those materials, or due to the material’s potential or kinetic energy. 1.2 Minimum lifecycle requirements This…

This document provides the guidelines, minimum requirements and performance characteristics intended to guarantee that manufactured systems intended for on-site/field use (i.e. outside the laboratory) provide reliable and reproducible results. This document specifies the requirements for technologies that enable on-site detection and quantification of Legionella spp. and L. pneumophila using a…

This document specifies the general requirements for sampling, preservation, handling, transport and storage of all water samples for physicochemical, chemical, hydrobiological and microbiological analyses and determination of radiochemical analytes and activities. Guidance on the validation of storage times of water samples is provided in ISO/TS 5667-25. This document is not applicable to water…

This document specifies a method of determining the moisture content of a test sample of solid biofuels by drying in an oven and is used when the highest precision is not needed, e.g. for routine production control on site. The method described in this document is applicable to all solid biofuels. The moisture content of solid biofuels (as received) is always reported based on the total mass of…

1 Scope 1.1 General This Standard specifies requirements for workplace electrical safety necessary for the practical safeguarding of workers during activities such as the installation, removal, inspection, operation, maintenance, and demolition of electric conductors and electric equipment, as well as work in proximity of energized electrical equipment. 1.2 Application While it can be…

This document applies to nuclear power plants with water cooled reactors. This document does not apply to earthquakes stronger than the design basis earthquake. This document specifies guidance on the actions to be taken in preparation for and following an earthquake at a nuclear power plant. This document is intended to be used as a guideline for decision making regarding continued operation,…
