Understanding IEC 61298-2: The Standard for Process Measurement and Control Performance
In the world of industrial automation, accuracy and reliability aren't just goals—they are requirements. To ensure that instruments perform consistently under varying conditions, the International Electrotechnical Commission developed the IEC 61298 series. Specifically, IEC 61298-2 focuses on the methods and procedures for evaluating the performance of process measurement and control devices.
Whether you are a manufacturer testing a new pressure transmitter or an engineer validating a control loop, understanding this standard is essential for ensuring operational excellence. What is IEC 61298-2?
The full title of the standard is “Process measurement and control devices - General methods and procedures for evaluating performance - Part 2: Tests under reference conditions.”
While Part 1 of the series covers general considerations, Part 2 provides the "how-to" for conducting tests. It defines the specific procedures to determine how an instrument performs when environmental and operational factors (like temperature, humidity, and power supply) are kept at a constant, "ideal" state. The Importance of Reference Conditions
Before you can understand how an instrument fails or drifts in extreme heat or vibration, you must first establish its "baseline." Testing under reference conditions allows engineers to:
Establish Accuracy: Determine the intrinsic error of the device.
Ensure Repeatability: Verify that the device provides the same output for the same input multiple times.
Comparative Analysis: Create a standardized data set that can be compared against other manufacturers or models. Key Testing Procedures Covered
IEC 61298-2 outlines several rigorous testing cycles. The most critical include: 1. Accuracy and Hysteresis Tests
The standard requires a series of "calibration cycles." Typically, this involves increasing the input signal in steps (e.g., 0%, 25%, 50%, 75%, 100%) and then decreasing it back to zero. This reveals: Linearity: How closely the output follows a straight line.
Hysteresis: The difference in output at the same input point depending on whether you are "going up" or "coming down" the scale. 2. Dead Band Testing
This procedure measures the smallest change in input signal that results in a measurable change in output. For high-precision control, a low dead band is vital. 3. Repeatability and Reproducibility
The standard defines how to conduct multiple test runs over a short period to see if the device can replicate its own results consistently. 4. Step Response and Frequency Response
IEC 61298-2 isn't just about static accuracy; it's about timing. These tests evaluate how quickly a device responds to a sudden change in input (Step Response) and how it handles oscillating signals (Frequency Response). Who Should Follow IEC 61298-2?
Manufacturers: To provide standardized data sheets that customers can trust.
Calibration Labs: To ensure their certification processes align with international benchmarks.
End Users/Engineers: To verify that the equipment they have purchased meets the technical specifications required for their specific process.
IEC 61298-2 is the backbone of performance evaluation in the process industry. By following these standardized testing procedures, organizations can move away from guesswork and toward data-driven reliability. When an instrument is "IEC 61298-2 compliant," it means its performance has been vetted under a microscope of international consistency. ) required for an IEC 61298-2 audit?

IEC 61298 is a critical international standard for Process measurement and control devices. It is published in multiple parts and covers general methods and procedures for evaluating the performance of industrial-process measurement and control devices (such as transmitters, sensors, and controllers).
Here is the content breakdown of the IEC 61298 series:
IEC 61298-1: General procedures
- Defines the general rules for testing and evaluating the performance of process measurement and control devices.
- Covers test conditions (temperature, humidity, power supply).
- Specifies reference conditions and uncertainties.
- Defines the acceptance of test results and reporting.
IEC 61298-2: Reference conditions and tests for inherent accuracy

Key Takeaway for Content Creation: If you are writing a technical document, test plan, or product manual, you should refer to the IEC 61298 series as the basis for performance evaluation and type tests for process instruments. It is commonly used alongside IEC 61326 (EMC) and IEC 61010 (safety).
If you actually meant a different number (e.g., 61298-2, or another standard like 61260 or 61290), please clarify.
It seems you are asking for a deep review of IEC 61298, but the number appears slightly off. The correct standard is likely IEC 61298 (Parts 1–5), which covers Process measurement and control devices – General methods and procedures for evaluating performance.
However, if you meant IEC 61215 (terrestrial photovoltaic (PV) modules – design qualification and type approval) or IEC 61850 (power utility automation), please clarify. I will proceed with a deep review of IEC 61298 as requested.
4.3 Input/Output Tests
The standard defines the method for determining the performance of the device:
- Number of Points: Typically, measurements are taken at 5 points distributed over the range (0%, 25%, 50%, 75%, 100%).
- Direction: The test is performed in an upward direction (0% to 100%) and a downward direction (100% to 0%).
- Cycles: usually 3 to 5 measurement cycles are required to establish a statistical baseline.
Acceptance criteria and tolerances
- Standard specifies test conditions and how to report results; pass/fail limits are typically product- or application-specific (manufacturer specs or purchaser requirements), not universally fixed in the standard.
❌ Not sufficient for:
- Safety device certification (need IEC 61508)
- Wireless devices (no battery life or RSSI testing)
- Software validation (no code coverage or coding standard checks)
- Explosive atmospheres (use IEC 60079 series)
How IEC 61298 Differs from Other Key Standards
Confusion often arises because several IEC standards deal with industrial instruments. Here is a clear differentiation:
| Standard | Primary Focus | Key Question It Answers | | :--- | :--- | :--- | | IEC 61298 | Performance testing | "How accurate, repeatable, and stable is this device?" | | IEC 61508 | Functional safety | "Will this device fail safely if something breaks?" | | IEC 61326 | EMC (Electromagnetic compatibility) | "Does nearby radio noise or a lightning strike affect it?" | | IEC 60529 | Ingress protection (IP rating) | "Can dust or water get inside?" |
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.
Part 1: General Introduction and Definitions
This foundational document sets the stage. It defines critical terminology that engineers must use consistently:
- Measurand: The physical quantity being measured (e.g., pressure, temperature).
- Range: The limits within which the instrument is intended to measure.
- Accuracy: The closeness of the indicated value to the true value.
- Repeatability: The ability to produce the same output under identical conditions.
- Hysteresis: The difference in output when the measurand increases vs. decreases.
- Drift: Gradual change in output over time with constant input.
Without Part 1, two engineers might argue over what "error" means. With it, they have a shared dictionary.
6. Reporting of Results
The standard mandates that results be reported in a specific manner, typically using tables or graphs. The report must clearly distinguish between:
- Maximum Error: The largest deviation observed during the test.
- Mean Error: The average of errors observed over multiple cycles.
Important Note: IEC 61298-2 emphasizes that conformity (how well the device matches a specific curve or line) is only valid if the device is non-linear (e.g., a square root extractor). For linear devices, linearity is often derived from the intrinsic error data.
5.4 Repeatability
The closeness of agreement between successive measurements of the same value of the same quantity carried out under the same conditions of measurement.
