The standard defines the method for determining the performance of the device:
Adhering to IEC 61298-2 protects both the manufacturers who build process instruments and the plants that deploy them: iec 612982
– Details how external factors like temperature, vibration, and supply voltage fluctuations impact the device.
Stability of the device over extended periods under reference conditions. The IEC 61298 Series Hierarchy
: The closeness of agreement among consecutive measurements of the same input variable under identical operating conditions. 4. Methodological Testing Steps If you share with third parties, their policies apply
Devices must prove they can respond consistently regardless of the direction from which an input value is reached. Testing looks for deviations caused by internal friction, mechanical play, or electronic lagging. 3. Repeatability Trials
: Measures the precise speed and time delay an instrument takes to settle after a sudden change.
In the world of industrial automation, a small error in a sensor can lead to a massive failure in a chemical plant or power station. This standard acts as the foundational script for how these devices are validated: IEC 61298-2:2008 The standard defines the method for
It ensures that safety-critical installations—such as emergency shutdown systems in chemical processing or custody-transfer flow systems—rely on instruments with verified tolerances.
The standard is for manufacturers, calibration labs, and end-users to compare devices from different suppliers under repeatable conditions.
Typical reference parameters dictated by the framework include: Standard Reference Control Band Relative Humidity Maintained within a stable non-condensing range (e.g., Atmospheric Pressure Power Supply (Electrical) Rated nominal voltage and nominal frequency Pneumatic Supply Specified nominal pressure Critical Metrological Performance Metrics Tested
Specifically, Part 2 focuses on . These are the "ideal" environmental and operational conditions under which a device is meant to operate. Testing under these conditions allows manufacturers to determine the intrinsic accuracy and performance capabilities of the device without the influence of external variables like extreme temperatures or vibration.
