Scope 1.1 This procedure defines the long-term thermal resistance (LTTR) of a foam product as the value measured after 5-year storage in a laboratory environment and provides means for its prediction based on an accelerated laboratory test. 1.2 This procedure, based on ASTM standard test methods ASTM C1303 and ASTM C518, can be applied to a wide range of preformed as well as field…

Domaine d’application 1.1 Cette procédure définit la résistance thermique à long terme (RTLT) d’un produit de mousse comme étant la valeur mesuré après 5 ans d’entreposage dans un environnement de laboratoire et fournit des moyens de prédiction basés sur un essai accéléré en laboratoire. 1.2 Cette procédure, basée sur les méthodes d’essai normalisées ASTM ASTM C1303 et ASTM C518, peut être…

This document specifies: — How to uniquely identify Digital Items (and parts thereof); — How to uniquely identify IP related to the Digital Items (and parts thereof), for example abstractions; — How to express the relationship between the two above identifiers; — How to deal with varying levels of functional granularity for Digital Item identifiers; — How to uniquely identify…

IEC TR 62839-1:2025 describes the product specific rules (PSR) for wires and cables used for communication, data, control and command. These PSR are applicable in case the life cycle assessment (LCA) results are intended to be used in external communication in the form of an environmental product declaration (EPD), as laid out in ISO 14021, ISO 14025, ISO 14026 and ISO 14067. These PSR are…

IEC TS 62586-3:2025 Describes a procedure used for maintenance tests of individual power quality instruments. Users of these instruments need to ensure the conformity of the individual power quality instrument for stationary use with the requirements of IEC 62586‑1. This is achieved by periodic maintenance tests as defined in this document.

IEC TS 63263:2025 describes a test method for evaluating the lifetime of winding wires under electrical high frequency voltage impulses (with partial discharges) at elevated temperatures. This method is only applicable as a comparative examination under a given sample preparation and testing environment. The comparative nature of this document lies in the fact that the lifetime under partial…

Ce document fournit également une classification ainsi que des exigences relatives aux spécifications commerciales des V.C.D. Il vise à harmoniser la terminologie utilisée à l’échelle internationale. La présente norme fournit un…

This document specifies methods to determine 226Ra by alpha spectrometry in supply water, drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling, handling and test sample preparation. The detection limit depends on the sample volume, the instrument used, the background count rate, the…

This document specifies calibration methods for a pyranometer using a pyrheliometer as a reference instrument. Three methods are specified in this document. a)       Alternating sun and shade method. This method uses a shading disc to alternately shade and unshade a pyranometer to compare with the tracking pyrheliometer. The test pyranometer can be horizontal, on a fixed tilt or tracking…

This document specifies a method of determining the characteristic fusion temperatures of ash from hard coal. NOTE            Descriptors: fossil fuels, ash, ashes, tests, high temperature tests, determination, and fusibility.
