IEC 61514-2:2013 specifies design reviews and tests intended to measure and determine the static and dynamic performance, the degree of intelligence and the communication capabilities of single-acting or double-acting intelligent valve positioners. The tests may be applied to positioners which receive standard analogue electrical input signals (as specified in IEC 60381) and/or digital signals via a data communication link and have a pneumatic output. This second edition cancels and replaces the first edition published in 2004 and constitutes a technical revision. The significant changes with respect to the previous edition are: The standard has been optimized for usability and the test procedures have been reviewed regarding applicability for use in test facilities. Impractical test procedures were removed or modified.
