IEC 61508 also does not cover low safety E/E/PE systems where a single E/E/PE system is capable of providing the necessary risk reduction and the required safety integrity of the E/E/PE system is less than safety integrity.

Applications and guidelines based on IEC 61508 have been established and executed by many industries prior to its formal publication.

But we cannot do this with the IEC 61508 vocabulary, which allows us no accidents; only hazardous events, and provides no guidance as to how causally near an event must be to harm to count as a hazardous event. In fact, the state of the usage is that most engineers of my acquaintance who are conversant with the standard would use the phrase hazardous event as equivalent to. IEC 61508 key safety indicators will be explained first because they are easier to understand. IEC 61508. IEC 61508 offers 4 (or 5) so called Safety Integrity Levels (SIL) for safety related systems: (no SIL, or SIL 0), SIL 1, SIL 2, SIL 3 and SIL 4. Sil0 reflects the lowest, and SIL4 the highest safety level. The SIL classification of safety related systems depends on the following parameters. 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-related systems (see 3.4.3 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. IEC 61508 part 2, systematic capability compliance routes Chapter 7.4.3 Requirements for systematic safety integrity (systematic capability) can be met by achieving one of the following compliance routes: - Route 1S: compliance with the requirements for the avoidance of systematic faults (see 7.4.6 and IEC 61508-3) and the requirements for the control of systematic faults (see 7.4.7 and IEC.

Pour l'IEC 61508, on ne peut avoir un avis aussi tranché parce qu'il s'agit d'une norme générique, applicable par tous. Mais, ainsi que vous l'avez souligné, elle est difficile à mettre en œuvre. Du coup, de fait, ce sont surtout les constructeurs de maté-riels qui l'appliquent Mesures. La notion de SIL (Safety Integri-ty Level, niveau d'intégrité de la sécurité. IEC 61508, the foundation for IEC 61511, was first introduced in 2000 and was subsequently updated in 2010. Nevertheless 12 years on from the release of IEC 61511 edition 1 in 2003 we find ourselves still using the same edition, that is until now. The second edition of IEC 61511 is in the final stages of publication and like with the second edition of IEC 61508 there are some significant.
