标准摘要
[中文适用范围]： 本部分IEC 60512用于评估SC 48B范围内的连接器，这些连接器用于支持IEEE 802.3远程供电应用的点对点连接的平衡单对通信布线。本文件的目的是详细说明一个测试计划，以确定IEC 63171系列中定义的单对连接器组在分离（拔出）步骤中按照IEC 60512-9-3通过电流时，能够承受至少100次机械操作的能力。本文件不涵盖单对连接器的多点供电应用。 [外文原描述]： IEC 60512-99-003:2023 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 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.
