IEC/TR 63097:2017(E) provides standards users with guidelines to select a most appropriate set of standards and specifications. These standards and specifications are either existing or planned, and are provided by IEC or other bodies also fulfilling use cases.
It also aims at creating a common set of guiding principles that can be referenced by end-users and integrators who are responsible for…
Coaxial communication cables - Part 1-206: Environmental test methods - Climatic sequence
IEC 61196-1-206:2017 specifies the method of test to determine the stability of transmission performance of a finished RF coaxial cable when subjected to a set of temperatures, temperature changes, and humidity stresses that would accelerate exposures observed in storage and transportation.
This edition includes the following significant technical changes with respect to the previous edition:…
Câbles coaxiaux de communication - Partie 1-206: Méthodes d'essai d'environnement - Séquen...
L’IEC 61196-1-206:2017 spécifie la méthode d'essai pour déterminer la stabilité de la qualité de transmission d'un câble coaxial RF fini soumis à un ensemble de températures, de variations de température et de contraintes liées à l’humidité, qui sont susceptibles d’accélérer les expositions observées pendant le stockage et le transport.
Cette édition inclut les modifications techniques…
Surge arresters - Part 8: Metal-oxide surge arresters with external series gap (EGLA) for overhead t...
IEC 60099-8:2017 covers metal-oxide surge arresters with external series gap (externally gapped line arresters (EGLA)) that are applied on overhead transmission and distribution lines, only to protect insulator assemblies from lightning-caused flashovers. This document defines surge arresters to protect the insulator assembly from lightning-caused over-voltages only. Therefore, and since metal-…
Parafoudres - Partie 8: Parafoudres à oxyde métallique avec éclateur extérieur en série (EGLA) pour ...
IEC 60099-8:2017 concerne les parafoudres à oxyde métallique avec éclateur extérieur en série (parafoudres de ligne avec éclateur extérieur) utilisés sur les lignes aériennes de transmission et de distribution, uniquement pour protéger les ensembles isolateurs contre les contournements provoqués par la foudre. Le présent document définit des parafoudres destinés à protéger l'ensemble…
Cocoa beans — Specification and quality requirements
ISO 2451:2017 specifies the requirements, classification, sampling, test methods, packaging and marking for cocoa beans.
Recommendations relating to storage and disinfestation are given as a guide in Annexes G and H respectively. Annex I is for informative purposes only and sets out a sampling procedure for preliminary quality analysis which can be adopted by agreement of all interested parties.
Explosive atmospheres - Part 43: Equipment in adverse service conditions
IEC TS 60079-43:2017(E) which is a Technical Specification, provides guidance for equipment for use in explosive atmospheres in environments which may include ambient temperatures below -20 °С, and additional adverse conditions, including maritime applications. The purpose of this document is to provide recommendations to be considered for the design, manufacture and use of equipment. It is…
