Testing devices under ideal, highly controlled reference conditions.
While "IEC 612982" may have been the starting point, the reality is far more significant. is poised to be a landmark revision that refines and defines how we ensure the performance of industrial instrumentation. By clarifying its scope, modernizing its terminology, and strengthening its alignment with other key standards, the new edition lays a stronger, clearer foundation for measurement accuracy.
The standard is undergoing a major transition with the development of Edition 3.0 . Managed by Technical Committee TC 65/SC 65B, the updated framework governs the performance evaluation of process measurement and control devices under reference conditions. The new draft standard ( prEN IEC 61298-2:2024 ) revises the older 2008 version. It bridges the gap between classic analog instrumentation and modern digital control architectures. iec 612982 new
Evaluating dead band and mechanical play demands a meticulous upscale and downscale profile. The system drives an incoming variable forward to target points without allowing any overshooting, holds for stabilization, logs metrics, pushes to 100% capacity, and retraces downscale. The resulting delta highlights hidden structural friction, loop lagging, and tracking drift. 3. Repeatability and Reproducibility Arrays
IEC 61298-2 is the referee of the process control industry. It strips away the marketing terminology and forces manufacturers to prove their performance data using mathematically sound, repeatable methods. For an end-user, purchasing equipment compliant with IEC 61298-2 ensures that the "±0.1% accuracy" printed on the datasheet is a verified scientific fact, not a theoretical best-case scenario. By clarifying its scope, modernizing its terminology, and

The series is divided into several parts, each receiving specific updates to reflect current testing methodologies: The new draft standard ( prEN IEC 61298-2:2024
The complete IEC 61298 framework serves as a core benchmark for industrial process equipment. It ensures that regardless of whether a device processes a pressure, temperature, or flow signal, its behavioral characteristics are evaluated identical to competitor models. The framework is divided into four distinct parts:
The upcoming standard establishes a modernized framework for evaluating the performance and functional characteristics of industrial process measurement and control devices under strict reference conditions . Developed by the International Electrotechnical Commission Sub-Committee 65B (Devices & process analysis), this new version officially replaces the aging 2008 second edition. It adapts metrology practices to align with modern digital industrial infrastructure.
