1   Scope

  This part of [IEC 60512](/search?q=IEC%C2%A060512)
   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](/search?q=IEC%C2%A063171) 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](/search?q=IEC%C2%A060512%E2%80%919%E2%80%913) during the separation (unmating) step. 
This document does not cover multidrop powering applications of single-pair connectors.
