: Previously, the 61298 series was the go-to for evaluating almost all process control performance. Now, PMTs are standardized separately under the IEC 62828 series The Impact
Before testing, devices are subjected to established reference conditions (e.g., ) for a designated period to ensure thermal stability. Calibration Cycle: A five-point minimum calibration test ( of span) is performed to measure intrinsic error.
For decades, industrial process control has relied on a silent backbone of standards. Among these, the has been the gold standard for testing and evaluating the performance of process measurement instruments. However, with the recent release of the IEC 612982 new revision (formally IEC 61298-2:2025), the landscape of industrial calibration, vibration testing, and environmental simulation has shifted dramatically.
: Documenting the steady-state electrical draw or pneumatic air consumption under exact reference benchmarks. Drift Assessments
Adopting the updated standard offers major practical advantages to stakeholders across the automation value chain:
Previous humidity tests were steady-state (e.g., 95% RH at 40°C). The introduces "condensation cycling."
: It delivers clear, compliant blueprints for developing and verifying new smart control devices, facilitating faster global market entry.
: Measuring the time required for an output to settle within a designated percentage of its final value following a sudden change in input.
: The guidelines accommodate legacy analogue systems as well as advanced digital instruments embedded with modern software protocols.
The most significant "new" development regarding IEC 61298-2 is its transition to a third edition. A Pre-Release Version (PRV)
