Le présent document décrit les types de peinture et de systèmes de peinture couramment utilisés pour la protection contre la corrosion des structures en acier.
Il fournit également des lignes directrices pour le choix de systèmes de peinture adaptés aux différents environnements (voir l'ISO 12944-2), excepté les catégories de corrosivité CX et la catégorie Im4 telles que définies dans l…
Iron ores — Determination of total iron content — Part 4: Potentiometric titration method
This document specifies a potentiometric titration method for the determination of total iron content of iron ores, using potassium dichromate as titrant after reduction of the iron(III) by tin(II) chloride and titanium(III) chloride. The excess reductant is then oxidized by potassium dichromate solution.
This method is applicable to total iron contents between a mass fraction of 29,04 % and a…
Information technology — Internet of media things — Part 2: Discovery and communication API
This document specifies the abstract class of a media thing (MThing), which is a basic component to construct Internet of media things. The MThing class contains the basic APIs to:
— discover other MThing(s) in the network;
— connect/disconnect MThing(s);
— support transactions (e.g. payments) using media tokens between MThings.
