EN 61514:2002

Industrial-process control systems - Methods of evaluating the performance of valve positioners with pneumatic outputs

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.

SR 65B, was submitted to the formal vote and was approved by CENELEC as EN 61514 on 2001-12-01.
The following dates were fixed:
- latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2002-12-01
- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2004-12-01
__________
Endorsement notice
The text of the International Standard IEC 61514:2000 was approved by CENELEC as a European
Standard with agreed common modifications as given below.

1 Scope and object
Replace the first paragraph by :
This European Standard specifies tests designed to determine the static and dynamic performance of
single-acting or double-acting analogue 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.
Positioners with pulsed or digital input signals, positioners with digital controllers and positioners with
pulsed outputs are outside the scope of this standard.
