标准范围

IEC 62808:2015规定了隔离装置的设计、分析和鉴定要求,用于确保冗余安全系统电路的电气独立性,或IEC 60709中规定的安全电路和低级电路之间的电气独立性。本标准包括关于确定适用于隔离装置的最大可信故障的指南。最大可信故障可作为基于其他标准(如IEC TS 61000-6-5或IEC 62003)的测试中使用的测试水平的基础。

IEC 62808:2015 establishes requirements for the design, analysis and qualification of isolation devices used to ensure electrical independence of redundant safety system circuits, or between safety and lower class circuits, as specified in IEC 60709. This standard includes guidance on the determination of the maximum credible fault that is applied to the isolation devices. The maximum credible fault can be used as a basis for the test levels used in testing based on other standards (e.g. IEC TS 61000-6-5 or IEC 62003).
