Determines the static and dynamic performance of single-acting or double-acting analogue positioners.

IEC 61514:2000 specifies tests designed to determine the static and dynamic performance of single-acting or double-acting valve positioners. 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.
NOTE For positioners with pulsed or digital input signals, equivalent criteria may be applied. The methods described may not fully apply to positioners with digital controllers or positioners with pulsed outputs.
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 this standard are intended for use by manufacturers to determine the performance of their products, and by users, or independent testing establishments, to verify manufacturers\' performance specifications. This publication is to be read in conjunction with IEC 61514-2:2013.
