Le présent document spécifie une méthode d’essai pour déterminer le tassement d'un isolant en vrac, appliqué horizontalement dans les combles ventilés. Cette méthode d’essai mesure les effets des variations cycliques de température et d’humidité.

This document describes a gas chromatography – ion mobility spectroscopy (GC-IMS) method for the determination of the concentration of siloxanes in biomethane. The method is applicable to the following siloxanes: —     hexamethyldisiloxane (L2); —     octamethyltrisiloxane (L3); —     decamethyltetrasiloxane (L4); —     dodecamethylpentasiloxane (L5); —     hexamethylcyclotrisiloxane (D3); —    …

This document specifies: a)       a method for determining the hydrolytic resistance of the interior surfaces of glass containers when subjected to attack by water at (121 ± 1) °C for (60 ± 1) min. The resistance is measured by determining the amount of sodium and other alkali metal or alkaline earth oxides in the extraction solution using flame atomic emission or absorption spectrometry (flame…

This document specifies: a)       a method for determining the hydrolytic resistance of the interior surfaces of glass containers when subjected to attack by water at (121 ± 1) °C for (60 ± 1) min. The resistance is measured by titration of a known aliquot portion of the extraction solution produced with hydrochloric acid solution, in which case the resistance is inversely proportional to the…

Le présent document décrit une méthode de chromatographie en phase gazeuse ‒ spectroscopie de mobilité ionique (CG-SMI) pour la détermination de la concentration de siloxanes dans le biométhane. La méthode s'applique aux siloxanes suivants: —     hexaméthyldisiloxane (L2); —     octaméthyltrisiloxane (L3); —     décaméthyltétrasiloxane (L4); —     dodécaméthylpentasiloxane (L5); —    …

This document specifies test conditions for determining the seasonal performance characteristics of air to water heat pumps for space heating with electrically driven compressors with or without supplementary heater. In the case of air to water heat pumps for space heating consisting of several parts with refrigerant or water connections, this document applies only to those designed and supplied…

This document provides a powerful decision-making tool for persons that either have clear professional development goals or uncertainties related to the progression of their career paths, including minimum education and training requirements for many of the maritime-related occupations. It aims to assist candidates to take the necessary steps to meet their goals. This document seeks to assist…

This document: —     defines requirements for vacuum insulation panels (VIPs) with silica or glass fibre core, which are used for thermal insulation of buildings; —     outlines required product properties, their performance, test methods and rules for conformity evaluations, identification and labelling; —     provides a test method to determine ageing factors and the influence of the linear…

This document specifies an acceptance sampling system of single sampling plans for inspection by variables, primarily designed for use under the following conditions: a)       where the inspection procedure is applied to an isolated lot of discrete products all supplied by one producer using one production process; b)       where only a single quality characteristic, x, of this process is taken…

IEC 60079-17:2023 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 60079-17:2023 applies to users and covers only those factors directly related to the inspection and maintenance…
