ANSI/ISA-75.13.01:2013

ANSI/ISA-75.13.01-2013, Method of Evaluating the Performance of Positioners with Analog Input Signals and Pneumatic Output, specifies methods for evaluating the performance of valve positioners with analog input signals and pneumatic output. It provides detailed procedures for testing static and dynamic behaviors, including calibration cycles, accuracy, dead band, hysteresis, conformity, repeatability and effects of environmental factors such as supply pressure, temperature, humidity, vibration, electromagnetic interference and mechanical shocks.This standard covers test setup requirements, actuator descriptions, environmental conditions, supply tolerances, flow capacity, steady-state consumption, locked-stem pressure gain and accelerated lifecycle testing. Dynamic response tests include frequency and step response analyses, along with guidance on signal generation and data presentation. By defining consistent evaluation criteria and reporting formats, this standard promotes uniformity in instrumentation testing and supports the needs of manufacturers, users and independent testers.
