Plastics — Polyols for use in the production of polyurethanes — Determination of water content
This document specifies methods used to measure the water content of polyols employed as polyurethane raw materials.
Method A is a manual amperometric method which has been included to better define the principles of the Karl Fischer measurement. Amperometric methods are applicable to a wide range of polyols, including those which have enough colour to obscure a visual end-point. Method B…

This document provides an example of the relation between the characterization of certain macroscopic properties of metallic powders and their spreadability in an PBF-LB/M AM machines.
This relation is based on a new technique combining measurements inside a PBF-LB/M machine and image processing developed to quantify the homogeneity of the powder bed layers during spreading.
In this document, the…

Le présent document fournit un exemple de la relation entre la caractérisation de certaines propriétés macroscopiques des poudres métalliques et leur étalabilité dans les machines PBF-LB/M de FA.
Cette relation repose sur une nouvelle technique combinant les mesurages à l’intérieur de la machine PBF-LB/M et le traitement d’image, développée pour quantifier l’homogénéité des couches du lit de…
This document provides three shoe size conversion tables covering the major shoe sizing systems (Mondopoint, European and United Kingdom), as well as China, Japan, the Republic of Korea and United States. The tables are based on measurement of foot length, this being the logical starting point for any shoe size marking system. The tables contain the following information:

La présente norme s’applique aux tuyaux de sections circulaires en béton armé ou non armé dont l’écoulement se fait par gravité et qui véhiculent des eaux d’égout sanitaire, des eaux d’égout pluvial, ou les deux. Ces tuyaux peuvent également être utilisés comme ponceaux.
La présente norme s’applique aux tuyaux et aux branchements latéraux monolithiques en béton armé d’un diamètre de 200 mm à 3…
Electronic displays - Part 3-9: Evaluation of optical performance - Display sparkle contrast
IEC 62977-3-9:2023 specifies standard measurement conditions and methods for determining the sparkle contrast of direct-view displays which comprise display matrix elements to render real 2D images on a flat panel and an anti-glare layer. This document excludes measurement of sparkle, which is intentionally obtained by the specular reflection from reflecting flakes in coatings and paints.

Le présent document définit un schéma conceptuel pour les couvertures. Une couverture est une mise en correspondance d'un domaine spatial, temporel ou spatiotemporel avec des valeurs d'attributs partageant le même type d'attribut. Un domaine de couverture se compose d'un ensemble de positions directes dans un espace de coordonnées qui peut être défini en termes de dimensions…
Geographic information — Schema for coverage geometry and functions — Part 1: Fundamentals
This document defines a conceptual schema for coverages. A coverage is a mapping from a spatial, temporal or spatiotemporal domain to attribute values sharing the same attribute type. A coverage domain consists of a collection of direct positions in a coordinate space that can be defined in terms of spatial and/or temporal dimensions, as well as non-spatiotemporal (in ISO 19111:2019, “parametric…
