Safety system receives SIL3 certification from TÜV

May 2005 News

Yokogawa Electric Corporation announces that on 10 March, 2005, TÜV Rheinland (TÜV), a German certification organisation, certified the compliance of the Yokogawa's ProSafe-RS Safety System with the IEC 61508 and IEC 61511 international standards and approved its use in SIL3 applications. ProSafe-RS is the world's first safety system to receive SIL3 certification under the IEC 61511 standard.

The IEC 61511 functional safety standard for the process automation field was established by the International Electrotechnical Commission (IEC) in 2004. A safety system that meets the IEC 61511 standard will constantly monitor the status of oil, natural gas, petrochemical, and other process applications and ensure safety by shutting down a plant if any condition is detected that exceeds a preset threshold.

In addition to acquiring IEC 61508 certification for general functional safety, Yokogawa's ProSafe-RS has been certified as meeting the IEC 61511 standard for process automation. This latest certification of IEC 61508 and IEC 61511 compliance attests to the high level of Yokogawa's technology and the quality of its safety instrumented system. The company is playing an expanding role in the worldwide process control and safety system market.

Yokogawa is resolved to further enhance its capability to provide solutions centred on the world-class CENTUM series production control system and the ProSafe-RS Safety System, and is committed to achieving the top position in the global industrial automation market by 2010.

* SIL3: safety systems must be tested by a third party to be certified for SIL. The risk factor of a plant with SIL3 safety measures is 1/10 000, while that without such measures is 1/1000. The risk factor of a plant with SIL1 safety measures is 1/100, while that without such measures is 1/10.
