IEC 62828-5:2020

Reference conditions and procedures for testing industrial and process measurement transmitters - Part 5: Specific procedures for flow transmitters

IEC 62828-5:2020 establishes specific procedures for testing flow transmitters used in measuring and control systems for industrial process and for machinery control systems. For general test procedures, reference is to be made to IEC 62828-1:2017, applicable to all types of industrial and process measurement transmitters.
This document – together with IEC 62828-1:2017 – is the reference standard for testing every type of flow transmitter, not only for liquids but also for gases and for steam.
In this document, "industrial flow transmitters" consistently covers all types of flow transmitters used in measuring and control systems for industrial process and for machinery.

Conditions de référence et procédures pour l'essai des transmetteurs de mesure industriels et de processus - Partie 5: Procédures spécifiques pour les transmetteurs de débit

L'IEC 62828:2020 établit les procédures spécifiques d'essai des transmetteurs de débit utilisés dans les systèmes de mesure et de commande des processus industriels et des systèmes de commande des machines. Pour les procédures d'essais générales, référence doit être faite à l'IEC 62828-1:2017, applicable à tous les types de transmetteurs de mesure industriels et de processus.
Le présent document (avec l'IEC 62828-1:2017) est la norme de référence pour soumettre à essai tous les types de transmetteurs de débit, non seulement pour les liquides, mais également pour les gaz et la vapeur.
Dans le présent document, le terme "transmetteurs industriels de débit" couvre tous les types de transmetteurs de débit utilisés dans les systèmes de mesure et de commande des processus industriels et des machines.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governm
