適用范圍：1.1 This part of IEC 61508 contains the definitions and explanation of terms that are used inparts 1 to 7 of the IEC 61508 series of standards.1.2 The definitions are grouped under general headings so that related terms can beunderstood within the context of each other. However, it should be noted that these headingsare not intended to add meaning to the definitions.1.3 IEC 61508-1, IEC 61508-2, 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.1.4 One of the responsibilities of a technical committee is, wherever applicable, to make useof 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.1.5 Figure 1 shows the overall framework of the IEC 61508 series and indicates the role thatIEC 61508-4 plays in the achievement of functional safety for E/E/PE safety-related systems.
