Describes a method applicable to products having aresenic contents equal to or greater than 0,1 mg/kg. As far as principle, the reagents and apparatus to be used are concerned, reference is made to ISO 2590, with some modifications added. For example, the reduction of arsenic by zinc is carried out in sulphuric acid medium. Provides information on the expression of results and the particulars to…

Describes a method applicable to products having arsenic contents equal to or greater than 0,2 mg/kg. As far as principle, reagents and apparatus to be used are concerned, reference is amde to ISO 2590. Provides information on the expression of results and the particular to be included in the test report. The annex lists ISO publications covering the same subject.

Describes a method applicable to products having arsenic contents euqal to or greater than 0,1 mg/kg. The principle consists in dissolving a test portion, acidifying it with hydrochloric acid solution and applying the general method as described in ISO 2590. Provides information on the expression of results and the particulars to be included in the test report. The annex lists ISO publications…

Specifies standardized nominal cross-section areas from 0.5 mm2 to 2 000 mm2, numbers and diameters of wires and resistance values of conductors in electric cables and flexible cords. Classifies conductors for: 1.Cables for fixed installations -Class 1, solid conductors; -Class 2, stranded conductors. 2.Flexible copper conductors -Class 5, -Class 6 (more flexible than Class 5). Includes table…

Spécifie la section nominale normalisée, de 0,5 mm2 à 2 000 mm2, ainsi que le nombre et le diamètre des brins et les valeurs de résistance des âmes des conducteurs et câbles électriques isolés. Classifie les âmes pour: 1. Câbles pour installations fixes: - classe 1, âmes massives; - classe 2, âmes câblées. 2. Âmes souples en cuivre: - classe 5; - classe 6 (plus souples que classe 5). Inclut un…

Describes the principle for making up insulator lots, the general rules for insulator sampling and their distribution for tests and the conditions for acceptance of a lot. Appendices contain operating characteristic curves for the checking procedure, giving the acceptance probability as a function of the quality of a lot. This publication has the status of a report.

Indique le principe de constitution d'un lot d'isolateurs, puis les règles générales de prélèvement des isolateurs et leur répartition pour les essais, et enfin les conditions d'acceptation d'un lot. En annexe, on trouve les courbes d'efficacité du contrôle qui donnent la probabilité d'acceptation en fonction de la qualité du lot. Le calcul statistique utilisé dans…

Establishes a system intended for application to all kinds of installation accessories for use in domestic and similar installations, such as socket-outlets, switches, push-buttons, pilot or signalling lights, etc. This publication has the status of a report.
