Relates to emission and immunity test methods for electrical and electronic equipment using various types of transverse electromagnetic (TEM) waveguides. This includes open (for example, striplines and EMP simulators) and closed (for example, TEM cells) structures, which can be further classified as one-, two-, or multi-port TEM waveguides. The frequency range depends on the specific testing…

Applies only to newly manufactured static var-hour meters of accuracy classes 2 and 3, for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only. For practical reasons, this standard is based on a conventional definition of reactive energy for sinusoidal currents and voltages containing the fundamental frequency only.…

Defines the requirements and quality assessment procedures for the type SC-PC (floating duplex)fibre optic patch cord connector, standard terminated on multimode fibre type A1a and A1b. The contents of the corrigendum of April 2004 have been included in this copy.

Applies to electrical appliances (including accessories) for household and similar use for drying and styling hair. Performance characteristics that are of interest to the user and specifies methods of measuring these characteristics are defined within this standard. The measuring procedures are developed for comparable tests. Requirements for performance are not specified within this standard.…

IEC 61754-4-1:2003 defines the standard interface dimensions of simplified receptacles for the type SC family of connectors. The parent connector for the type SC connector family is a single-position plug which is characterized by a cylindrical, spring-loaded butting ferrule(s) of 2,5 mm typical diameter, and a push-pull coupling mechanism. Keywords: standard interface dimensions of simplified…

Specifies the method of test for the determination of the proof and comparative tracking indices of solid insulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltages. The standard provides for the determination of erosion when required. Test results cannot be used directly for the evaluation of safe creepage distances when designing…

ISO 2303 specifies, for general purpose non-oil-extended, solution-polymerized rubbers (IR): physical and chemical tests on raw rubbers;standard materials, standard test formulation, equipment and processing methods for evaluating the vulcanization characteristics. Two mill-mixing procedures are described in this Internatioanl Standard and an internal mixer-mill mixing procedure is described in…

This National Standard of Canada is equivalent to International Standard ISO 19011:2002 (first edition, 2002-10-01). 1 Scope This International Standard provides guidance on the principles of auditing, managing audit programmes, conducting quality management system audits and environmental management system audits, as well as guidance on the competence of quality and environmental management…
