本国际标准描述了建立地震鉴定程序的方法，该程序将产生定量数据，以证明设备能够满足其性能要求。本文件适用于核设施中使用的电气、机械、仪表和控制设备/部件。本文件提供了设备抗震鉴定的方法和文件要求，以验证设备A？s在规定地震要求期间和/或之后执行规定性能要求的能力。本文件未规定抗震要求或性能要求。与质量保证、设备选择、系统设计和修改相关的其他方面不属于本文件的一部分。 由于抗震鉴定只是设备鉴定的一部分，本文件与IEC/IEEE 60780-323一起使用。 抗震鉴定证明设备A？在至少一次安全停堆地震（SSE/S2）期间和/或之后执行安全功能的能力。在SSE/S2之前，通过考虑设备老化和给定次数的低烈度运行基准地震（OBE/S1）的假设事件，证明了这种能力。如果设计规范中有规定，需要考虑的老化现象可能会增加设备对SSE/S2引起的振动的脆弱性。

This International Standard describes methods for establishing seismic qualification procedures that will yield quantitative data to demonstrate that the equipment can meet its performance requirements. This document is applicable to electrical, mechanical, instrumentation and control equipment/components that are used in nuclear facilities. This document provides methods and documentation requirements for seismic qualification of equipment to verify the equipment's ability to perform its specified performance requirements during and/or after specified seismic demands. This document does not specify seismic demand or performance requirements. Other aspects, relating to quality assurance, selection of equipment, and design and modification of systems, are not part of this document. As seismic qualification is only a part of equipment qualification, this document is used in conjunction with IEC/IEEE 60780-323. The seismic qualification demonstrates equipment's ability to perform its safety function(s) during and/or after the time it is subjected to the forces resulting from at least one safe shutdown earthquake (SSE/S2). This ability is demonstrated by taking into account, prior to the SSE/S2, the ageing of equipment and the postulated occurrences of a given number of lower intensity operating basis earthquake (OBE/S1). Ageing phenomena to be considered, if specified in the design specification, are those which could increase the vulnerability of equipment to vibrations caused by an SSE/S2.
