IEC 60512-99-003:2023

Connectors for electrical and electronic equipment - Tests and measurements - Part 99-003: Endurance test schedules - Test 99c: Test schedule for balanced single-pair connectors separating (unmating) under electrical load

IEC 60512-99-003:2023 is used for the assessment of connectors within the scope of SC 48B that are used in balanced single-pair communication cabling with remote power, in support of e.g., IEEE 802.3 remote powering applications for point-to-point connections.
The object of this document is to detail a test schedule to determine the ability of sets of single-pair connectors as defined in the IEC 63171 series to withstand a minimum of 100 mechanical operations with electrical load, where an electrical current is being passed through the connector in accordance with IEC 60512-9-3 during the separation (unmating) step.
This document does not cover multidrop powering applications of single-pair connectors.

Connecteurs pour équipements électriques et électroniques - Essais et mesures - Partie 99-003: Programmes d’essais d’endurance - Essai 99c: Programme d’essai des connecteurs à une seule paire symétrique lors de la séparation (désaccouplement) sous charge électrique

IEC 60512-99-003:2023 est utilisée pour l’évaluation des connecteurs dans le domaine d’application du SC 48B qui sont utilisés dans le câblage de communication symétrique à paire unique avec alimentation à distance, à l’appui, par exemple, des applications d’alimentation à distance IEEE 802.3 pour les connexions point à point. L’objet du présent document est de détailler un programme d’essai pour déterminer la capacité des ensembles de connecteurs à paire unique tels que définis dans la série CEI 63171 à résister à un minimum de 100 opérations mécaniques avec charge électrique, lorsqu’un courant électrique traverse le connecteur conformément à la CEI 60512-9-3 pendant l’étape de séparation (découplage). Le présent document ne couvre pas les applications d’alimentation multipoint des connecteurs à paire unique.

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, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or fo
