IEC 60512-99-003 Ed. 1.0 b:2023

This part of IEC 60512 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 singlepair 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.
