The maximum difference in output for the same input value when approached from opposite directions (upscale vs. downscale).
: It is designed for manufacturers validating device performance, independent laboratories creating reproducible test plans, and R&D engineers assessing accuracy and dynamic response. : The project for the third edition (ED3) is slated for final registration in December 2025 Core Focus of Part 2 iec 612982 new
While other standards analyze how a device reacts to environmental extremes or electrical interference, . These standardized laboratory environments strip away external variables (such as fluctuating temperatures or vibrating machinery), allowing testers to uncover the absolute baseline accuracy, linearity, and repeatability of a device. The maximum difference in output for the same

Understanding the New IEC 61298-2:2026 – Advanced Performance Evaluation for Process Instrumentation
Standardizes how to measure accuracy-related factors, including dead band, hysteresis, and error curves.
As described by the IEC Webstore , the standard applies to any process measurement and control device characterized by specific input and output variables, whether analogue or digital.
