Standardizes submerged arc furnace test conditions and methods to determine their main parameters and technical
characteristics. Applies to industrial three-phase submerged arc furnaces with rated power level of 1 000 kVA or more. Also applies to furnaces having one or more electrodes, other than three-phase furnaces.
Dimensions of panel areas and cut-outs for panel and rack-mounted industrial-process measurement and...
Serves as a guide for selection of panel cut-out sizes and instrument front dimensions so that users may plan installations with the assurance that equipment purchased will fit, and manufacturers can design to ensure conformance to users' needs. Recognizes three known modular elements: 12 mm and 20 mm, both from established European practice, and 12.5 mm, the module established in IEC 60473…
La présente Norme internationale spécifie les symboles graphiques pour les éléments de schémas cinématiques, englobant les produits de toutes les branches de l'industrie. Il faut employer les symboles spécifiés à l'exécution des schémas de la documentation technique, ainsi que dans la littérature technique et pédagogique. La présente Norme internationale est publiée en trois parties,…
The symbols system is intended for simplifying the preparation of diagrams of products in all branches of industry and is to be used in technical documentation as well as in technical and educational literature. It will facilitate the execution and understanding of such diagrams by specialists of different countries. This part contains Geneva and ratchet mechanisms as well as couplings and brakes.

Sodium hydroxide for industrial use — Determination of mercury content — Dithizone photometric metho...
Covers a method applicable to liquid or solid products having mercury contents greater than 0,05 mg/kg. The principle of determination is based on oxidation of the mercury contained in a test portion to mercury(II) ions by potassium permanganate in the presence of sulphuric acid, reduction of the excess oxidant, extraction in chloroform of the complex formed, and photometric measurement of the…
Sodium hydroxide for industrial use — Determination of mercury content — Flameless atomic absorption...
Covers a method applicable to liquid or solid products having mercury contents greater than 0,02 mg/kg. The principle of determination is based on oxidation of the mercury contained in a test portion to mercury(II) ions by potassium permanganate in the presence of sulphuric acid, reduction of the excess oxidant by hydroxylammonium chloride, reduction of the mercury(II) ions to mercury by tin(II)…
Sodium sulphate for industrial use — Determination of calcium content — Flame atomic absorption spec...
Specifies a method, the principle of which is based on acidification of a test portion with hydrochlorid acid, aspiration of the test solution into an acetylene-dinitrogen monoxide or acetylene-air-flame, and measurement of the absorption of the 422,7 nm line emitted by a calcium hollow-cathode lamp.
Specifies requirements for fittings for threaded connections, used mainly for industrial purposes. Table 1 contains diagrams ot types of fittings and their symbols. Tabulates the fitting dimensions (tables 2 to 10) with nominal sizes from DN 6 up to and including DN 80 (thread designation 1/8 to 3).
