Lo IEC 61508 è uno standard internazionale che disciplina l'intero ciclo di vita dei prodotti e dei sistemi elettrici, elettronici o elettronici programmabili (E/E/PE) relativi alla sicurezza, inclusi la loro applicazione, progettazione, utilizzo e manutenzione. È sviluppato dalla Commissione elettrotecnica internazionale (IEC) e ha come titolo Sicurezza funzionale dei sistemi elettrici Safety Critical Systems Handbook: A Straight forward Guide to Functional Safety, IEC 61508 (2010 EDITION) and Related Standards, Including Process IEC 61511 and Machinery IEC 62061 and ISO 13849 - Ebook written by David J. Smith, Kenneth G. L. Simpson. Read this book using Google Play Books app on your PC, android, iOS devices.

EN/IEC 62061 represents a sector-specific standard under IEC 61508. It describes the implementation of safety-related control systems on machinery and examines the overall lifecycle from the concept phase through to decommissioning. The machine should have been constructed in accordance with IEC 62061 or ISO 13849 but it may have to interface with and have an impact on a safety system designed to IEC 61511 & IEC 61508. The process in which the machine is installed may also have an impact on the safety requirements IEC/EN 62061, ”Safety of machinery: Functional safety of electrical, electronic and programmable electronic control systems”, is the machinery specific implementation of IEC/EN 61508.

The standard represents a comprehensive system for the implementation of safety-related electrical, electronic and programmable electronic con-trol systems. EN 62061 has been a harmonised standard since December 2005. EN 954-1, or alternatively EN ISO 13849-1, should be applied Functional Safety with the process industry is achieved using IEC 61511 (and normally in low demand mode of operation) where as functional safety of machinery is achieved using either IEC 62061 or ISO 13849 as either high demand mode or continuous mode of operation.
In automotive, the draft international standard ISO 26262 is becoming relevant for the passenger cars segment. IEC 61508 is still used for commercial vehicles
Functional Safety with the process industry is achieved using IEC 61511 (and normally in low demand mode of operation) where as functional safety of machinery is achieved using either IEC 62061 or ISO 13849 as either high demand mode or continuous mode of operation. IEC 62061 or ISO13849 are concerned only with the risk and functional safety
IEC 62061 is the machinery-specific implementation of IEC 61508. It provides requirements that are applicable to the system level design of all types of machinery safety-related electrical control systems and also for the design of non-complex subsystems or devices.
It includes recommendations for the design, integration and validation of safety-related electrical, electronic and programmable electronic control systems for
One drawback for AS 61508 in the machine safety sector, was that it involves a substantially more complex process in determining the overall reliability of a safety control system, in some situations being overly complex for a machine safety control system. AS IEC 62061 was published, as a daughter standard derived from AS 61508,
IEC 61508 for their specific functional safety requirements through additional derived standards. The most common in factory automation include IEC 61131-6 for safe programmable logic controllers (PLCs), IEC 62061 for industrial machinery, IEC 61800-5-2 for variable speed drives and IEC 61511 for industrial process control. All of these
However, rather than the EN 61508 series, application of EN 62061 or EN ISO 13849-1/-2 is recommended for end users or system integrators for determining safety levels, as they are much less complex.

È sviluppato dalla Commissione elettrotecnica internazionale (IEC) e ha come titolo the advent of IEC 61508 other industries, including the process industry, have elected to develop an industry specific derivative of the more general IEC 61508 for their own means in order to reduce the burden and complexity of complying with a very general standard such as IEC 61508. IEC 61508 first edition was published in 2000 but it wasn IEC 60906-1 is an international standard designed "to provide a standard for a safe, compact and practical 16 A 250 V AC system of plugs and socket-outlets that could be accepted by many countries as their national standard, even if not in the near future." EN/IEC 62061 represents a sector-specific standard under IEC 61508. It describes the implementation of safety-related control systems on machinery and Focus is put on requirements for SIL 3 HW development acc. to IEC 61508 and IEC 62061 as well as EN ISO 13849-1 and its practical realization.
