Industrial-process control systems - Methods of evaluating the performance of valve positioners with pneumatic outputs
Scope: This International Standard specifies tests designed to determine the static and dynamic performance of single-acting or double-acting analogue positioners. The tests apply to positioners which receive standard analogue input signals (as specified in IEC 60381-1, IEC 60381-2 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 document.
Testing is 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 document 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.
The closest liaison between the evaluating body and the manufacturer is indispensable during the tests, including the possibility for the manufacturer to influence the test programme based on the manufacturer's specifications for the instrument and comment on both the test programme and the results.
This document 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 are used where no other values are specified by the manufacturer or user. If other values are used, they will be stated. It is recognized that the manufacturer's specifications and instructions for installation and operation apply during all steps.
The tests specified in this document are not necessarily sufficient for instruments specifically designed for unusually arduous conditions. Conversely, a reduced series of tests can serve adequately for instruments designed to perform within a more limited range of conditions.
When a full evaluation, in accordance with this document, is not required or possible, only the tests which are required are performed and the results reported in accordance with the relevant parts of this document. In such cases, the test report will state that it does not cover the full number of tests specified herein.

Reference conditions and procedures for testing industrial and process measurement transmitters - Part 1: General procedures for all types of transmitters
Scope: This Part of IEC 62828 establishes a general framework for defining reference conditions and test procedures applicable for assessing the measurement performances of all types of industrial and process measurement transmitters (PMTs) used in measuring and control systems for industrial process and machinery.
For the purpose of this document, an analogue PMT is a process measurement transmitter with only analogue current and/or voltage output(s), irrespective the technology adopted and the complexity of the circuitry. All the other process measurement transmitters, with digital output(s) only or with hybrid analogue and digital output(s), are considered to be digital PMTs.
This document constitutes a common reference for the other parts of the IEC 62828 series.
Specific test procedures and additional requirements for given types of PMTs (pressure, temperature, level, flow, etc.) are covered by other parts of this series.
Sensing devices according to the IEC 60947 series are excluded from the scope of this document.
NOTE 1 In industrial and process applications, to indicate the process measurement transmitters, it is common also to use the terms "industrial transmitters", or "process transmitters".
NOTE 2 For better clarity, when the complete definition "industrial and process measurement transmitter" makes the sentence too long in this document, the short term "transmitter", or PMT, is used instead.
