IEC 60512-99-002:2022 is available as IEC 60512-99-002:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60512-99-002:2021 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 802.3btTM (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. This second edition cancels and replaces the first edition published in 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: Test group UEL has been revised with respect to the order of the test phases, the test severities and the requirements.
