scope:

This technical report is intended to provide information on the effects of engaging and separating under electrical load on the connector interfaces in cabling used to support IEEE 802.af (Power-over-Ethernet (PoE)) applications. The ISO/IEC/JTC1/SC25 sub-committee requested IEC SC48B to prepare an engaging and separating under electrical load test method to be referenced in their standards. This test method standard was published as 60512-9-3 Ed. 1 (2006). The SC48B/WG5 experts were concerned about the affect of engaging/separating under electrical load on the IEC 60603-7 series connector interfaces that would be typically used in the IEEE 802.af (PoE) applications. The experts developed a set of tests to evaluate the affects, the results of which are reported in this technical report. NOTE: "Engaging" and "Separating" are terms used in most IEC SC48 publications to describe the physical mating or un-mating of connectors. The terms are defined in the IEV in clause 581-08-08. The IEC 60603-7 series standards use the terms mating and un-mating throughout. To avoid confusion in reading this technical report and also the IEC 60603-7 series standards, it is important to know that the term engaging is equivalent to mating and the term separating is equivalent to un-mating.
