IEC 61298 Process Measurement and Control Devices, General Methods and Procedures for Evaluating Performance

Get Certified IEC 61298 for Instrument Performance Reliability

The IEC 61298 certification assures that process measurement and control equipment conforms to the specifications of the performance. Non-conformance is evidenced with the assistance of controlled laboratory tests, verification of calibration, and environmental stress. Certification increases acceptance of the products in world industrial markets and promotes regulatory and safety demands.

 • Includes transmitters, controllers, indicators, recorders, and analyzers. 

• Delimits ways of assessing both the static and dynamic performance. 

• Accounts for the influence of environmental and power supply. 

• Helps to certify products and maintain consistency in technical documentation.

• Performance test of pressure, temperature, flow, and level transmitters. 

• Industrial automation system certification. 

• Oil and gas, power plant, and chemical industries

• Verification of compliance with international process control markets.

IEC 61298 Common Challenges and Troubleshooting

Some of the typical pitfalls are the use of unstable environmental conditions, inappropriate calibration reference standards, signal noise interference, and inappropriate test sequencing. Poor grounding and shielding can corrupt performance measurements. These problems are reduced in laboratories through the use of calibrated, traceable instruments, controlled conditions, and standard test protocols.

IEC 61298 Technique, Process, and Data Collection

The input signals through the operating range are controlled to test the device under test. Measurement of the characteristic aspects, like accuracy and repeatability, is done initially, and then the dynamic tests to test the behavior of the response are conducted. The conditions of environmental stress can be added to notice the difference in performance. Measurements made encompass out-of-reference values, hysteresis curves, response time measurements, drift in response to changes in temperature, and fatigue in calibration degree prior to and following testing.

IEC 61298 Problem & Solution

Problem:
Malfunctioning or erratic functioning of process measurement and control instruments may result in ineffective operations, safety hazards, and non-compliance with regulations.

Solution:
The IEC 61298 limits the standardized procedures of performance evaluation in order to confirm the accuracy of the devices and their stability, as well as environmental resilience, to facilitate reliable and safe control of the process in industries.
