29、514:2002 BSI13June2002INDUSTRIAL-PROCESS CONTROL SYSTEMS Methods of evaluating the performance of valve positioners with pneumatic outputs 1 Scope and object This European Standard specifies tests designed to determine the static and dynamic performance of single-acting or double-acting analogue pos
30、itioners. The tests may be applied to positioners, which receive standard analogue input signals (as specified in IEC 60381 and IEC 60382) and have a pneumatic output. Positioners with pulsed or digital input signals, positioners with digital controllers and positioners with pulsed outputs are outsi
31、de the scope of this standard. Testing may be conducted either on a positioner alone, independently of an actuator, or on a positioner mounted and connected to a specific actuator, as a combined unit. The text makes clear where different approaches are required. The methods of evaluation given in th
32、is standard are intended for use by manufacturers to determine the performance of their products, and by users, or independent testing establish- ments, to verify manufacturers performance specifications. The closest liaison should be maintained between the evaluating body and the manufacturer. Note
33、 should be taken of the manufacturers specifications for 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 organiz
34、ation. 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 th
35、e 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 us
36、er. If other values are used, they should be stated. It is recognized that the manufacturers specifications and instructions for installation and operation should apply during all steps. The tests specified in this standard are not necessarily sufficient for instruments specifically designed for unu
37、sually arduous conditions. Conversely, a reduced series of tests may serve adequately for instruments designed to perform within a more limited range of conditions. When a full evaluation, in accordance with this standard, is not required or possible, those tests which are required should be perform
38、ed and the results reported in accordance with the relevant parts of this standard. In such cases, the test report should state that it does not cover the full number of tests specified herein.
