Industrial-process control valves –
Part 9. Test procedure for response measurements
from step inputs
1 Scope 
This Part of GB/T 17213 defines the testing and reporting of the step response of
control valves that are used in throttling closed-loop control applications. A control
valve consists of the complete, ready-to-use assembly of the control valve body, the
actuator, and any required accessories. The most probable accessory is a valve
positioner.
NOTE. For background, refer to technical report ANSI/ISA-TR75.25.02 [6]1).
The object of this Part is to define how to test, measure, and report control valve
response characteristics in an open-loop environment. This information can be used
for process control applications to determine how well and how fast the control valve
responds to the control valve input signal.
This Part does not define the acceptable control valve performance for process control
nor does it restrict the selection of control valves for any application. If this standard is
used for evaluation or acceptance testing, the parties may agree to documented
variations from these requirements.
The information using the defined test methods is specifically applicable to closed-loop
feedback control but may have some application to open-loop control applications. This
Part does not address valves used in on-off control service.
Tests specified in this Part may not be sufficient to measure the performance required
for all applications. Not all control valve applications will require this testing.
