.6) The IEC has not laid down any procedure concerning marking as an indication of approval and has no responsibility when an item of equipment is declared to comply with one of its standards. IEC 61508-5 has been prepared by sub-committee 65A: System aspects, of IEC technical committee FORMTEXT65: Industrial process measurement and controlFORMTEXT.
IEC 61508-6. Part six offers guidelines for applying IEC 61508 parts two and three. IEC 61508-7. The final portion of IEC 61508 provides the safety techniques and measures relevant to parts two and three. These are industry-wide methods that the standard employs for safety. What is the International Electrotechnical Commission (IEC)?
Introduction and Revision of IEC 61508 7 Fig. 3. E/E/PE system safety lifecycle (in realisation phase) from IEC 61508/Edition 2 Fig. 4. Software safety lifecycle (in realisation phase) from IEC 61508/Edition 2 Evidence of the need to adopt an approach that covers all phases of the Overall Safe-
61508-1 ? IEC: 1997 30 Version 4.0 05/12/97 7.1.4.4 Each phase of the overall safety lifecycle shall be divided into elementary activities with the scope, inputs and outputs specified for each phase. 7.1.4.5 The scope and inputs for each overall safety lifecycle phase shall be as specified in table 1.
IEC 61508 was intended that various industry sectors provide their own specific standards and guidelines as needed. Here we can see the relationship between 61508 and other standards, such as 61513 for the nuclear sector, 62061 for the machine safety sector, and 61511 for the process control sector.
IEC 61508-1, IEC 61508-2, IEC 61508-3 and IEC 61508-4 are also intended for use as stand-alone publications. The horizontal safety function of this international standard does not apply to medical equipment in compliance with the IEC 60601 series. The functional safety assessment was performed to the SIL 3 requirements of IEC 61508:2010. A full IEC 61508 Safety Case was created using the exida Safety Case tool, which also was used as the primary audit tool. Hardware and software process requirements and all associated documentation were reviewed.

management requirements of IEC 61508 SIL 3. The assessment of the FMEDA, done to the requirements of IEC 61508, has shown that the 3051 Pressure Transmitter with 4-20mA HART can be used in a high demand safety related system in a manner where the PFH is within the allowed range for SIL 2 according to table 3 of IEC 61508-1.
