IEC 61508-7:2000 电气/电子/可编程电子安全相关系统的功能安全 第7部分:技术和措施综述

1 This part of IEC 61508 contains an overview of various safety techniques and measures relevant to IEC 61508-2 and IEC 61508-3. NOTE The references should be considered as basic references to methods and tools or as examples, and may not represent the state of the art. 2 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-related systems (see 3.4.4 of IEC 61508-4). As basic safety publications, they are intended for use by technical committees in the preparation of standards in accordance with the principles contained in IEC Guide 104 and ISO/IEC Guide 51. IEC 61508 is also intended for use as a stand-alone standard. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its own publications. In this context, the requirements, test methods or test conditions of this basic safety publication will not apply unless specifically referred to or included in the publications prepared by those technical committees. NOTE 1 The functional safety of an E/E/PE safety-related system can only be achieved when all related requirements are met. Therefore it is important that all related requirements are carefully considered and adequately referenced. NOTE 2 In the USA and Canada, until the proposed process sector implementation of IEC 61508 (i.e. IEC 61511) is published as an international standard in the USA and Canada, existing national process safety standards based on IEC 61508 (i.e. ANSI/ISA S84.01-1996) can be applied to the process sector instead of IEC 61508. 3 Figure 1 shows the overall framework for parts 1 to 7 of this standard and indicates the role that IEC 61508-7 plays in the achievement of functional safety for E/E/PE safety-related systems.
