Evaluation International are pleased to announce the establishment of a national EMPHASIS ASSESSMENT register which is being made available to Evaluation International Member companies.  This register brings together all planned, in-progress and complete Emphasis Assessments, undertaken on behalf of the Sponsor Companies. 

In addition to this Evaluation International has established a Working Group to oversee the development of the Register and supporting services. Any organisations wishing to access the register or participate in the working group should email: enquiries@evaluation-international.com and a member of our team will be happy to assist.



Evaluation International has bilateral agreements with both EXERA and WIB. These agreements enable EI member companies to access the reports produced by these associations and to collaborate in working groups and projects. 

In addition, EI participates in a wider consortium of end-user organisations across Europe with member companies that operate on a global scale. The aim of this consortium is to ensure that the widest possible community of large-scale EC & I end-user organisations are provided with a platform on which to share knowledge, network, collaborate and share.

The consortium includes the following organisations:


EXERA – the French end-users association for industrial automation. [https://www.exera.com]
WIB – a process automation users association covering the Netherlands and Belgium. [https://www.wib.nl]
CLUI – the Italian Association for Automation and Instrumentation Systems. [http://www.cluias.it]

Electro-Pneumatic Valve Positioner, Model ARCApro Typ 827


This report deals with the results of tests of two single acting electro-pneumatic valve positioners model ARCApro Typ 827, manufactured by ARCA Regler GmbH, Germany in co-operation with Siemens A.G. The instruments were standard production models. The instruments are fully identical to the SIPART PS 2, valve positioner, manufactured by Siemens A.G. Germany. One positioner was mounted on an ARCA actuator/valve assembly. This instrument was not completely evaluated, but the tests were chosen from the full evaluation programme to show the performance of this type when connected to the ARCA integral mounting. The other positioner mounted on a Von Rohr valve/actuator assembly was only submitted to the vibration test. For details on the full evaluation the WIB report E 2684 T99 must be consulted.
