1 Scope 1.1 This Standard applies to 60-250°C single- or multiple-conductor jacketed or unjacketed, integral or nonintegral cables and single or multiple coaxial cables for telephone and other communication circuits such as voice, data, and audio for on-premise customer systems. These cables are not prohibited from containing one or more optical fibre members. For the purpose of this…

1 PURPOSE AND SCOPE This standard specifies requirements with respect to the physical, mechanical and dimensional characteristics of ductile-iron pipe intended for use in water pressure piping systems of diameters 75 mm through 1600 mm for bell and spigot-joint pipe and flanged-joint pipe, and diameters 75 mm through 600 mm for mechanical-joint pipe, as well as test methods applying to…

This European Standard specifies requirements for the qualification testing of welding procedures for the arc welding of tube to tube-plate joints in metallic materials by manual, partly mechanized, mechanized or automatic processes. This standard is a part of a series of standards. Details of this series are given in prEN ISO 15607, Annex A. Qualification by tube to tube-plate joint tests can be…

Applies to controllers and starters, which may include a series mechanical switching device, intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c.

This International Standard provides guidelines to enable translators and translation support staff to record, maintain and quickly and easily retrieve terminological information in connection with translation work. The quality of a translation can be measured partly in terms of linguistic elements, such as style and grammar, and partly in terms of the accurate use of the terminology involved.…

Deals with the safety of electric fishing machines, in which water may be electrified for catching fish or providing barriers to animals living in water. Examples are mains-operated and battery-operated electric fishing machines. The rated voltage of portable machines is less than 250 V, and less than 1000 V for fixed machines permanently connected to fixed wiring. For electric fence energizers,…

This section of IEC 61000-3 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by an equipment tested under specified conditions and gives guidance on methods of assessment. This section is applicable to electrical and electronic equipment having an input current up to and…

This part of ISO 4392 describes a method of determining the low speed characteristics of positive displacement rotary fluid power motors, of either fixed or variable displacement types. The method involves testing at slow speeds which may generate frequencies having a significant influence upon the steady continuous torque output of the motor and affect the system to which the motor would be…

La présente partie de l'ISO 4392 décrit une méthode de détermination des caractéristiques à basse vitesse des moteurs volumétriques rotatifs à cylindrée fixe ou variable. Cette méthode spécifie des essais à des basses vitesses qui peuvent créer des phénomènes périodiques ayant une influence significative sur le couple de sortie en régime permanent et affecter le système auquel le moteur est…
