This International Standard applies to proportional-integral-derivative (PID) pneumatic and
electric industrial-process controllers using analogue continuous input and output signals
which are in accordance with current international standards.
It should be noted that while the tests specified herein cover controllers having such signals,
they can be applied in principle to controllers having different but continuous signals. It should
be also noted that this standard has been written for pneumatic and electric industrial-process
controllers with only analogue components and is not necessarily to be used for controllers
with microprocessors.
This standard is intended to specify uniform methods of test for evaluating the performance of
industrial-process PID controllers with analogue input and output signals1).
The test conditions specified in this standard, for example the range of ambient temperatures,
power supply, etc., are used when no other values are agreed upon by the manufacturer and
the user.
When a full evaluation in accordance with this standard is not required, those tests which are
required shall be performed and the results reported in accordance with those parts of the
standard which are relevant. The testing program should be subject to an agreement between
manufacturer and user, depending on the nature and the extent of the equipment under
consideration.
