This part of IEC 60512 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.
