The colonization samplers described allow water quality to be assessed by providing a collection of macro-invertebrates indicative of the water quality at the sites of concern. They do not sample the natural invertebrate fauna, which may be restricted by physical conditions unrelated to water quality, and are to be used when studying lowland river waters of depth over 1 m. The deep water samplers…

1.1 This Standard specifies the minimum requirements for factory-built, single or multiple-piece roof vent flashings used to effect a permanent weather seal between the flashing and the vent pipe without the use of additional sealing materials around the vent pipe. Flashings fabricated on-site are not included. 1.2 The Standard includes requirements for material, quality of work, and…

IEC TS 62600-103:2024 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 TS 62600-103:2024 is concerned with the sub-prototype scale development of wave energy converters (WECs). It…

This document applies to civil structures of nuclear power plants with water cooled reactors in order to achieve the safety objectives given in ISO 4917-1. For other nuclear facilities the applicability of the document needs to be checked in advance, before it might be applied correspondingly. This document specifies the requirements for civil structures for the verification of their load-bearing…

This document provides a methodology for calculating greenhouse gas (GHG) emissions from the semiconductor and display industry. This document includes the manufacture of semiconductor devices, microelectromechanical systems (MEMS), photovoltaic (PV) devices and displays. This document allows to report GHG emissions for various purposes and on different bases, such as a per-plant basis, per-…

This document specifies a harmonized methodology for calculating greenhouse gas (GHG) emissions from the cement industry, with a view to reporting these emissions for various purposes and by different basis, such as, plant basis, company basis (by country or by region) or even international group basis. It addresses all the following direct and indirect sources of GHG included: —    Direct GHG…

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…

This document specifies a range of requirements and recommendations for the elements of construction, building assemblies, components, fittings and products that relate to the design and constructional aspects of usability and accessibility of buildings, i.e. access to buildings, circulation within buildings, egress from buildings during normal conditions, and evacuation in the event of a fire.…

Le présent document fournit des recommandations sur la description du sol sur le terrain et de son contexte environnemental. Il est applicable aux sites naturels, quasi-naturels, urbains et industriels. Les observations et les mesurages du sol peuvent être effectués sur un site de projet, sur une parcelle, sur une couche ou sur un horizon et sur des constituants spécifiques du sol. Il fournit…

Le présent document spécifie une méthode pour le prélèvement et la manipulation de vers de terre sur le terrain, comme prérequis à l'utilisation de ces animaux en tant que bio-indicateurs (par exemple, pour évaluer la qualité d'un sol en tant qu'habitat pour des organismes). Le présent document est utilisé pour tous les biotopes terrestres abritant des vers de terre. La conception…
