IEC 60050-692:2017给出了考虑电力系统可靠性和服务质量时使用的术语。这些概念根据以下部分进行分类: -系统概念； -电力系统的运行状态； -电力系统故障； -电力系统设备中断； -电力系统中的停电事件； -状态持续时间和可用性相关概念； -电力系统中断； -选定的客户中断措施； -大量电力系统负载/能量削减； -大量电力系统故障和措施； -供应绩效措施。 根据IEC指南108:2006，IEC 60050-692:2017具有水平标准的地位。该术语与IEV其他专业部分开发的术语一致。

IEC 60050-692:2017 gives the terminology used when considering the dependability and quality of service of electric power systems. The concepts are categorized according to the following sections:
- system concepts;
- operating states of electric power systems;
- failures in electric power systems;
- outages of electric power systems equipment;
- outage occurrences in electric power systems;
- state durations and availability related concepts;
- interruptions in electric power systems;
- selected customer interruption measures;
- bulk electric power system load/energy curtailments;
- bulk electric system failures and measures;
- supply performance measures.
IEC 60050-692:2017 has the status of a horizontal standard in accordance with IEC Guide 108:2006. This terminology is consistent with the terminology developed in the other specialized parts of the IEV.
