IEC 61298-2 is an international standard that acts as a "testing playbook" for industrial automation. It ensures that the sensors and control devices used in massive factories—which measure things like pressure, temperature, and flow—are accurate and reliable. iTeh Standards Why This Standard Matters
This standard is part of the broader IEC 61298 series, which establishes a consistent framework for evaluating process instrumentation. By providing a standardized baseline for "ideal" laboratory conditions, Part 2 ensures that performance data—such as accuracy, hysteresis, and dead band—remains comparable across different manufacturers and test laboratories. Scope and Applicability iec 612982
This part ensures regulatory bodies, auditors, and customers can compare data from different suppliers without guessing. IEC 61298-2 is an international standard that acts
Your quality system requires annual calibration. You suspect that your high-end Coriolis meters could go two years. Perform an endurance test per IEC 61298-4 on a sample unit: measure drift every month for 12 months. If the drift after 12 months is still <50% of the product specification, you have justification under ISO 9001 to extend the interval to 24 months. Document the method and results per Part 5. The standard is foundational for manufacturers

To ensure compliance with IEC 61298, manufacturers must design and test their devices according to the standard's requirements. Certification bodies, such as the International Electrotechnical Commission (IEC) and the German Institute for Accreditation (DAkkS), offer certification programs for devices that meet the standard's requirements.
The standard is foundational for manufacturers, calibration labs, and end-users to compare devices from different suppliers under repeatable conditions.
