Connectors for electrical and electronic equipment - Tests and measurements - Part 99-002: Endurance test schedules - Test 99b: Test schedule for unmating under electrical load

IEC 60512-99-002:2019 is used for testing connectors within the scope of SC 48B that are used in twisted pair communication cabling with remote power, such as ISO/IEC 11801 Class D (or better), balanced cabling in support of IEEE Std 802.3bt™, (PoE Plus – Power over Ethernet Plus).
The object of this document is to detail a test schedule to determine the ability of pairs of connectors to withstand a sequence of tests with a total of 100 engagements and separations. The electrical current is passed through the connectors during the separation (unmating) step only, in accordance with IEC 60512-9-3.
Keywords: Connectors, Engaging and Separating connectors

Connecteurs pour équipements électriques et électroniques - Essais et mesures - Partie 99-002: Programmes d’essais d’endurance – Essai 99b: Programme d’essai pour le désaccouplement sous charge électrique

IEC 60512-99-002:2019. est utilisée pour soumettre à essai des connecteurs relevant du domaine d’application du SC 48B, qui sont utilisés dans les câblages de communication à paires torsadées permettant une alimentation à distance, tels que les câblages symétriques de la classe D (ou d'une classe correspondant à une fréquence supérieure) de l’ISO/IEC 11801, à l’appui de la norme IEEE 802.3bt™ (alimentation électrique par câble Ethernet améliorée/PoE Plus, Power over Ethernet Plus).
L’objet du présent document est de détailler un programme d’essai permettant de déterminer l’aptitude des paires de connecteurs à supporter une séquence d'essais de 100 accouplements et désaccouplements au total. Le courant électrique traverse les connecteurs au cours du désaccouplement uniquement, conformément à l’IEC 60512-9-3.
Mots clés: connecteurs, enclenchement et séparation des connecteurs

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 for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60512-99-002 has been prepared by subcommittee 48B: Electrical
connectors, of IEC technical committee 48: Electrical connectors and mechanical structures for
electrical and electronic equipment.
The text of this International Standard is based on the following documents:
FDIS Report on voting
48B/2703/FDIS 48B/2725/RVD

Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated at the time of the next edition.
A list of all parts in the IEC 60512 series, published under the general title Connectors for
electrical and electronic equipment – Tests and measurements, can be found on the IEC
website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
