Applicable to products having contents expressed in chlorine equal to or more than 30 mg/kg. Potentiometric titration of the chloride ions with standard volumetric silver nitrate solution in a nitric acid-acetone-water medium, at a temperature below 20 0C, using a silver measurement electrode and a colomel reference electrode or a pair of silver-mercury(I) sulphate electrodes. Has also been…

The Standard specifies certain characteristics of the oil. Descriptions and permissible values are given of aspect, colour, odour, relative density at 20/20 °C, refractive index at 20 °C, optical rotation at 20 °C, miscibility with 70 % (V/V) ethanol at 20 °C, acid value, ester value, ester value after acetylation, carbonyl value, and apparent citronellol (rhodinol) content. Most of the values…

Two methods of titration depending on whether the end point is detected visually or electrometrically are specified. The visual method is only applicable to colourless solutions but can be used when no electrometric apparatus is available. The electrometric method, whether by direct titration or back-titration, is the more accurate one and for this reason recommended. The principle of the test…

Applies to all kinds of written documents, for example manuscripts, printed works, books, journal articles, directions for use and standards. Numbering of divisions and subdivisions is advocated if this - clarifies the sequence, importance and interrelation of individual divisions and subdivisions; - simplifies search and retrieval of certain passages in the text; - makes possible the citation of…

1. Scope 1.1 This standard applies to a detergent resistant water emulsion floor polish suitable for general application on all nonwood floors, and for sealed wood floors. It should not be used on unsealed wood, cork or magnesite floors. The floor polish described in this standard is not buffable, but it may be maintained with spray buffing techniques…

Establishes the use of IEC standard test fingers in testing protection against mechanical hazard on the normal conditions of use due to contact through openings in commercial refrigerated cabinets intended for the sale and/or display of food products. For tests in respect of accidental electrical contact reference should be made to appropriate IEC tests.

This International Standard specifies the for 8 mm Type S motion-picture projector take-up reel/spool spindles.

Describes a method applicable to products having water contents equal to or greater than 0,05 % (m/m). The principle of determination is based on the reaction of water with a solution of iodine and sulphur dioxide in a pyridine-methanol mixture (Karl Fischer reagent) which is standardized previously by titration of an exactly known mass of water. The end point of the reaction is then determined…

S'applique au système de base de Tailles Canada Standard pour vêtements de dames. Elle décrit le système, la méthode d'élaboration et regroupe sous forme de tableaux les mensurations en unités métriques pour les gammes normalisées de tailles représentant presque complètement la population féminine adulte. Les chaussures, la bonneterie et les gants ne font pas l'objet du…

Décrit les modifications apportées au système de Tailles Canada Standard présenté dans la norme CAN2-49.201-M. Entre autres, deux mesures déterminantes du corps, la longueur de tronc et la hauteur d'enfourchure, ont été remplacées respectivement par deux mesures déterminant la taille qui sont la longueur du dos et la hauteur à la ceinture, dans le but de mieux adapter le système aux…
