scope:

This International Standard defines procedures and specifications for the evaluation of Process Control Systems (PCS) during the phase of selection between different bids and during the Factory Acceptance Test (FAT). The methods of evaluation proposed in this standard are intended for use mainly by users, engineering companies, or independent test laboratories, to verify manufacturers' bids during the tender (as described in Part 1 of this Standard) or the provided Process Control System during the FAT procedure (as described in Part 2 of this Standard). The specification and test procedures specified in this standard apply to a large variety of automation systems, both based on conventional technology (e.g. 4-20 mA field devices) and based on Intelligent Field Devices (IFD) with fieldbus communication of any kind. For this reason, the tests specified in this standard are not necessarily sufficient for automation systems specifically designed for special duties. In such cases, user and manufacturer can define additional tests for assessing specific functions or performances.
