We know, another day in product development, yet another standard to comply with - however, it really does pay off. There are many advantages to ensuring functional safety with In 1997 the IEC published the standard IEC 61508, Functional safety of electrical/electronic/programmable electronic safety-related systems. The phrase "electrical/electronic/programmable electronic" is cumbersome and is often shortened to E/E/PE, which some pronounce "ee-ee-pee-ee" and others such as myself "eepee". IEC 61508-7:2010 contains an overview of various safety techniques and measures relevant to IEC 61508-2 and IEC 61508-3.The references should be considered as basic references to methods and tools or as examples, and may not represent the state of the art. This edition constitutes a technical revision. 2.1 IEC 61508 Requirements The following is an abbreviated summary of relevant requirements from IEC 61508: 7.4.4.12 states that safety related software development "shall be used according to a suitable programming language coding standard." 7.4.4.13 states, "The coding standard shall specify good programming practice, proscribe Part 7 contains important information for those doing product development work on equipment to be certified per IEC 61508. Annex A addresses control of random hardware failures. It contains a reasonable level of detail on various methods and techniques useful for preventing or maintaining safety in the presence of component failures.

It is also currently being used as a basis for developing other sector standards (e.g. machinery, process) and product standards (e.g. power drive systems). It is therefore influencing the development of E/E/PE safety-related systems and products across all sectors. safety barriers on an installation. For instrumented safety systems, special reference is made to IEC 61508 and this document as the recommended standard for specification, design and operation of such safety systems. Whereas IEC 61508 describes a fully risk based approach for determining SIL (Safety Integrity Level) requirements, IEC 61508 is an international standard published by the International Electrotechnical Commission consisting of methods on how to apply, M.J.M. Houtermans, "SIL and Functional Safety in a Nutshell" (Risknowlogy Best Practices, 1st Edition, eBook in PDF, ePub, and iBook format, 40 Pages) SIL and Functional Safety in a Nutshell - eBook safety management requirements of IEC 61508 SIL 3. The assessment of the FMEDA, done to the requirements of IEC 61508, has shown that the 2051 Pressure Transmitter with 4-20mA HART can be used in a low demand safety related system in a manner where the PFD AVG is within the allowed range for SIL 3
