TUV approval for Yokogawa

On 10 March 2005, TUV certified the compliance of the Yokogawa ProSafe-RS Safety System with the IEC 61508 and IEC 61511 international standards and approved its use in SIL3 applications.

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.
