IEC 61514:2000 pdf free download.Industrial-process control systems - Methods of evaluating the performance ofvalve positioners

with pneumatic outputs.

The closest liaison should be maintained between the evaluating body and the manufacturer. Note should be taken of the

manufacturer’s specifications br the instrument when the test programme is being decided, and the manufacturer should be invited

to comment on both the test programme and the results, His comments on the results should be included in any report produced by the testing organization.

This standard is intended to provide definitions of positioner elements, actions, and characteristics, to specify uniform methods

of measuring performance errors and effects of influence quantities on those characteristics, and to describe methods of reporting and evaluating the results of the measurement data obtained.

The test conditions described in this publication (for example range of ambient temperatures and power supply) relate to Conditions which commonly arise in use. Consequently, the values specified shall be used where no other values are specified by the

manufacturer or user. If other values are used, they should be stated. It is recognized that the manufacturer’s specifications and instructions for installation and operation should apply during all steps.
