IEC 61298-2 is designed for a broad range of industrial applications. It is applicable to any device that requires performance validation, including but not limited to: Pressure transmitters Differential pressure transmitters Flow meters Level sensors Temperature transmitters Control valves (positioners)
Understanding IEC 61298-2: The Standard for Performance Evaluation of Process Control Devices iec 612982
These tests determine the basic, intrinsic quality of the instrument without external interference.
Implementing IEC 61298-2 offers immediate advantages across the entire automation supply chain: Beyond the major scope and structural changes, the
: It provides a standardized framework for all parties (owners, installers, and vendors) to agree on the scope of loop testing before a plant is commissioned .
Engineers designing safety-critical or high-precision systems (such as chemical reactors, oil refineries, or pharmaceutical plants) require absolute certainty regarding instrument error. Utilizing IEC 61298-2 compliant hardware ensures that safety lifecycle calculations (like SIL ratings) and process control loops are designed using verified, predictable data. For Calibration Laboratories It is applicable to any device that requires
Key tests outlined in Part 2 include:
This procedure measures the smallest change in input signal that results in a measurable change in output. For high-precision control, a low dead band is vital. 3. Repeatability and Reproducibility
