Introduction
This document is the CDV of the Third Edition of IEC 61010-1, with the unique requirements for test
and measurement circuits removed from this Part 1 document to form a new part 2-030 Special
requirements for testing and measuring circuits.
In order to manage the integrity of part 1 and part 2-030 while both of them are being prepared
simultaneously it is necessary to circulate all of IEC 61010-1 voting documents to national
committees with the matching companion of IEC 61010-2-030 and vice versa. National committees
are asked to note that all votes will need to take both drafts into account and that one cannot
proceed without the other. All comments will be considered by both WG1 and WG2 to determine
which document (or both documents) may be affected by the comment.
This CDV has a new informative annex L “Safety testing after repair or modification”. National
committees are asked to pay particular attention to this annex when voting and in particular
comment on whether it should be included or not.
Introduction au CDV de la CEI 61010-1 édition 3
Ce document est le projet de CDV de la troisième édition de la CEI 61010-1, dont les exigences
uniques pour les circuits de test et de mesure ont été retirées de cette partie 1 pour constituer une
nouvelle partie 2-030 Prescriptions particulières pour les circuits de test et de mesure.
De manière à gérer l’intégrité des documents Partie 1 et Partie 2-030 qui ont été préparés
ensemble, les documents de vote du projet de troisième édition de la CEI 61010-1 et du projet
associé correspondant de la CEI 61010-2-030 doivent être diffusés obligatoirement ensemble. Tous
les votes devront tenir compte des deux projets.
Les comités nationaux doivent comprendre que les résultats de vote devront être les mêmes pour
les deux documents parce que ces documents sont indissociables.
Tous les commentaires devront être examinés à la fois par les WG1 et WG2 pour déterminer quels
documents peuvent être affectés par le commentaire.
Le CDV comporte une nouvelle annexe L informative « Essais de sécurité après réparation ou
modification ». Il est demandé aux comités nationaux de prêter une attention particulière sur cette
annexe au moment du vote et de préciser s’il elle doit être incluse ou non.
