IEC 61298-2 , titled "Process measurement and control devices – General methods and procedures for evaluating performance – Part 2: Tests under reference conditions," provides a standardized framework for evaluating the performance of industrial instrumentation. It ensures that performance data for analog and digital devices is reliable and comparable by testing them under controlled, ideal conditions. IEC Webstore Key Evaluation Areas

Yet, for decades, manufacturers used different methods to test and characterize their instruments. How do you guarantee that a sensor from a German supplier and a valve positioner from a Japanese vendor will perform predictably on the same control loop in Texas?

For an end-user (plant engineer):

Reference Conditions: Tests are conducted under strictly defined ambient and supply conditions (e.g., constant temperature and stable power supply) to isolate the device's inherent performance.

Exclusions: Typically excludes Process Measurement Transmitters (handled by IEC 62828). iec 612982

IEC 61298 is a multipart standard for Process measurement and control devices – General methods and procedures for evaluating performance.

Limitations & Gaps

1. No explicit cybersecurity testing

Given the rise of IIoT and Ethernet/IP field devices, IEC 61298 does not address communication robustness, protocol conformance, or security attacks (e.g., DoS, replay). You must complement with IEC 62443. IEC 61298-2 , titled "Process measurement and control

that are defined by specific input/output variables and transfer functions. iTeh Standards Key Performance Features Evaluated

But Vendor B's data sheet includes statements like: "Tested according to IEC 61298-1 through -5. Reference accuracy: ±0.1% at 20°C. Additional temperature error: ±0.02% per 10°C. Long-term drift: 0.1% per year." Vendor A simply says "high accuracy." How do you guarantee that a sensor from
