Villamos/elektronikus/programozható elektronikus biztonsági rendszerek működési biztonsága. 1. rész: Általános követelmények (IEC 61508-1:2010)

Functional safety of electrical/electronic/programmable electronic safety-related systems. Part 1: General requirements (IEC 61508-1:2010)

1.1 This International Standard covers those aspects to be considered when electrical/electronic/programmable electronic (E/E/PE) systems are used to carry out safety functions. A major objective of this standard is to facilitate the development of product and application sector international standards by the technical committees responsible for the product or application sector. This will allow all the relevant factors, associated with the product or application, to be fully taken into account and thereby meet the specific needs of users of the product and the application sector. A second objective of this standard is to enable the development of E/E/PE safety-related systems where product or application sector international standards do not exist. 1.2 In particular, this standard a) applies to safety-related systems when one or more of such systems incorporates electrical/electronic/programmable electronic elements; NOTE 1 In the context of low complexity E/E/PE safety-related systems, certain requirements specified in this standard may be unnecessary, and exemption from compliance with such requirements is possible (see 4.2, and the definition of a low complexity E/E/PE safety-related system in 3.4.3 of IEC 61508-4). NOTE 2 Although a person can form part of a safety-related system (see 3.4.1 of IEC 61508-4), human factor requirements related to the design of E/E/PE safety-related systems are not considered in detail in this standard. b) is generically-based and applicable to all E/E/PE safety-related systems irrespective of the application; c) covers the achievement of a tolerable risk through the application of E/E/PE safety-related systems, but does not cover hazards arising from the E/E/PE equipment itself (for example electric shock); d) applies to all types of E/E/PE safety-related systems, including protection systems and control systems; e) does not cover E/E/PE systems where – a single E/E/PE system is capable on its own of meeting the tolerable risk, and – the required safety integrity of the safety functions of the single E/E/PE system is less than that specified for safety integrity level 1 (the lowest safety integrity level in this standard). f) is mainly concerned with the E/E/PE safety-related systems whose failure could have an impact on the safety of persons and/or the environment; however, it is recognized that the consequences of failure could also have serious economic implications and in such cases this standard could be used to specify any E/E/PE system used for the protection of equipment or product; NOTE 3 See 3.1.1 of IEC 61508-4. g) considers E/E/PE safety-related systems and other risk reduction measures, in order that the safety requirements specification for the E/E/PE safety-related systems can be determined in a systematic, risk-based manner; h) uses an overall safety lifecycle model as the technical framework for dealing systematically with the activities necessary for ensuring the functional safety of the E/E/PE safety-related systems Túl hosszú
