适用范围：1.1 This part of IEC 61508 contains an overview of various safety techniques and measuresrelevant to IEC 61508-2 and IEC 61508-3.The references should be considered as basic references to methods and tools or asexamples, and may not represent the state of the art.1.2 IEC 61508-1, IEC 61598-2, IEC 61508-3 and IEC 61508-4 are basic safety publications,although this status does not apply in the context of low complexity E/E/PE safety-relatedsystems (see 3.4.3 of IEC 61508-4). As basic safety publications, they are intended for use bytechnical committees in the preparation of standards in accordance with the principlescontained in IEC Guide 104 and ISO/IEC Guide 51. IEC 61508-1, IEC 61508-2, IEC 61508-3and IEC 61508-4 are also intended for use as stand-alone publications. The horizontal safetyfunction of this international standard does not apply to medical equipment in compliance withthe IEC 60601 series.1.3 One of the responsibilities of a technical committee is, wherever applicable, to makeuse of basic safety publications in the preparation of its publications. In this context, therequirements, test methods or test conditions of this basic safety publication will not applyunless specifically referred to or included in the publications prepared by those technicalcommittees.1.4 Figure 1 shows the overall framework for parts 1 to 7 of IEC 61508 and indicates the rolethat IEC 61508-7 plays in the achievement of functional safety for E/E/PE safety-relatedsystems.
