The new IEC 61298-2:2022 standard introduces several key
The new edition is designed to be used by for validating performance claims, test laboratories for designing reproducible test plans, and R&D engineers for benchmarking industrial automation components. It acts as a foundational reference for future product-specific standards across the process industry.
The standard mandates that the overall accuracy statement of a device must be derived from three key components: The new edition is designed to be used
The "old" version served the industry well for the era of analog 4-20 mA loops. But the industrial world has changed. We now live in the age of IIoT (Industrial Internet of Things), wireless transmitters, and high-speed digital protocols (Ethernet-APL, Profinet). The update closes the gap between legacy reliability tests and modern digital realities.
: Lower the input signal incrementally from the maximum range value back to zero to close out the testing sequence.
The maximum difference between output values for the same input when approached from different directions.
IEC 61298-2 is the foundational standard that specifies general methods and procedures for conducting tests and reporting on the functional and performance characteristics of process control devices.
