Note: A device can be IEC 61298-tested (accurate) but not safe (IEC 61508). Conversely, a safety-certified transmitter can have poor accuracy—but that is usually unacceptable.

This is the introduction and overarching guide to the entire series. It details the general principles and procedures applicable to all process control devices, including both models. Part 1 is the starting point for understanding how to structure the overall evaluation process.

How far the device's reading deviates from the absolute truth.

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?

While IEC 61298 has been widely adopted, there are still challenges to be addressed, including:

Adhering to IEC 61298-2 protects both the manufacturers who build process instruments and the plants that deploy them:
