标准摘要
[中文适用范围]： IEC 60512-99-002:2021+AMD1:2025 CSV 用于评估 SC 48B 范围内的连接器，这些连接器用于带远程电源的双绞线通信电缆，例如符合 ISO；IEC 11801 1 D 类或更高级别的平衡电缆，以支持 IEEE 802.3btTM（以太网供电，支持来自电源设备高达 90 W 的功率）。本文件的目的是详细说明一个测试计划，以确定连接器组在分离（脱开）步骤中承受至少 100 次带电机械操作的能力，其中电流按照 IEC 60512 9 3 标准通过连接器。此第二版取消并取代了 2019 年发布的第一版。此版本构成技术修订。此版本与前一版本相比包括以下重大技术变化：测试组 UEL 已根据测试阶段的顺序、测试严酷程度和要求进行了修订。 [外文原描述]： IEC 60512-99-002:2021+AMD1:2025 CSV 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.
