The standard, titled "Process measurement and control devices – General methods and procedures for evaluating performance – Part 2: Tests under reference conditions," is part of a larger series designed to ensure reliable, repeatable, and comparable measurement results across industrial automation.
The series focuses on the "Process measurement and control devices" and provides general methods and procedures for evaluating performance. Specifically:
The updated Part 3 now makes more extensive use of cross-references to dedicated standards for specific influence quantities. For example, instead of trying to redefine electromagnetic compatibility (EMC) testing, the new version of IEC 61298-3 will directly refer to the relevant sections of the series on EMC. This approach makes the standard leaner and more technically robust.
This document provides a comprehensive overview and summary of . This standard is a critical part of the process measurement and control industry, specifically addressing how manufacturers verify the performance of their devices. iec 612982

The primary goal of IEC 61298-2 is to establish an instrument's baseline performance. By eliminating external environmental influences, test laboratories can isolate and measure the intrinsic characteristics of the device.
To fully implement Part 2, it is often used alongside other parts of the series: For example, instead of trying to redefine electromagnetic
Like all good technical standards, IEC 61298 is not static. It evolves to keep pace with technological advancements and industry needs. While the 2nd Edition (2008) remains valid, a comprehensive is currently under development and being finalized as of 2026. This new edition introduces several key changes.
: Measures the precise speed and time delay an instrument takes to settle after a sudden change.
In the real world, instruments do not fail suddenly; they drift slowly. Part 4 focuses on . It describes accelerated life testing and endurance runs to measure: This standard is a critical part of the
For manufacturers, IEC 61298-2 compliance serves as a benchmark for product data sheets and quality assurance. For end-users in industries like chemical processing or energy generation, it provides an objective basis for comparing competitive products and ensuring that critical control components meet the necessary precision standards for safe operation.
The standard details specific procedures for evaluating different aspects of a device's operation. These are typically documented in a structured Evaluation Report .
