1 Scope
This part of IEC 60512
is used for the assessment of connectors within the scope of SC 48B that are used
in twisted pair communication cabling with remote power, such as ISO/IEC 11801‑1 Class D, or better, balanced cabling in support of IEEE 802.3bt™ (Power over Ethernet, supporting up to 90 W from the power sourcing equipment).
The object of this document is to detail a test schedule to determine the ability
of sets of connectors to withstand a minimum of 100 mechanical operations with electrical
load, where an electrical current is being passed through the connectors in accordance
with IEC 60512‑9‑3 during the separation (unmating) step.
