The newest version of IEC 61298-2, titled "Process measurement and control devices – General methods and procedures for evaluating performance – Part 2: Tests under reference conditions", is currently under development as Edition 3.0. It has a forecasted publication date of June 5, 2026.
5. Power Supply Harmonics & DC Ripple Immunity
Modern plants use variable frequency drives (VFDs) and switch-mode power supplies that inject harmonics and high-frequency ripple onto the 24V DC loop. The old test used a pure DC source. iec 612982 new
IEC 61298-2 standard is currently undergoing a major transformation. After nearly two decades, a new third edition (IEC 61298-2:2026) The newest version of IEC 61298-2 , titled
For manufacturers and engineers, this standard is the go-to for ensuring that a device's "advertised" performance matches its actual behavior. By testing under reference conditions Drift Measurements : Documentation of start-up and long-term
The rollout of these standards is phased, with the previous 2008 versions remaining active until the final publication of each part: IEC 61298-2:2008
- CRC errors
- Communication timeouts
- Data payload corruption

IEC 61298-2 focuses specifically on tests under reference conditions. This is the baseline testing phase where the device is tested in an "ideal" environment to determine its intrinsic accuracy and operational capabilities before external stressors (like heat or humidity) are introduced.
