Summary of IEC 61298-3 Testing

Devices that require IEC 61298-3 testing include critical components in a wide range of industries, including manufacturing, chemical processing, energy production, and more. The performance of these devices can significantly impact product quality, operational safety, and environmental compliance.

Therefore, it’s crucial to assess how external factors, or ‘influence quantities,’ such as temperature, humidity, vibration, electromagnetic interference, and others, can affect device performance.

Objectives of Vibration Testing

Durability Assessment: To evaluate the device’s ability to endure continuous or intermittent vibrations without degradation of performance or structural integrity.

Performance Stability: To ensure the device maintains its specified performance levels, including accuracy and functionality, while being subjected to vibration.

Design Verification: To verify that the design and construction of the device are adequate to resist vibrations encountered during transportation, installation, and normal use.

IEC 61298-3 Laboratory Testing Procedures

The IEC 61298-3 testing series offers testing to ensure that process measurement and control devices are capable of operating reliably and safely under the conditions they will encounter in real-world applications.

Temperature and Humidity Testing

Objective: Assess device performance under various temperature and humidity conditions.

An environmental chamber is utilized for this test. It can control and vary temperature and humidity levels. This simulates a range of conditions from extreme cold to heat, and dry to humid environments.

The device undergoes testing under scenarios that replicate potential operational conditions. This includes experiencing rapid environmental changes.

Key performance metrics are monitored during the IEC 61298-3 test. These include the device’s accuracy, response time, and electrical properties. The aim is to ensure the device remains effective under varied conditions.

Vibration Testing

Objective: Evaluate the device’s resistance to vibrations that could occur during transportation or operation.

Vibration testing employs a vibration table or shaker system. This equipment can simulate different vibration frequencies and amplitudes. It mimics real-world conditions the device may face.

The device is securely mounted on the table. Predefined vibration patterns are applied. These patterns represent operational conditions and transport vibrations.

The goal is to identify design weaknesses. Device performance and physical integrity are assessed throughout the testing process. Post-test, the device is inspected for damage and tested for any performance degradation.

Electromagnetic Compatibility (EMC) Testing

Objective: Ensure the device’s performance is not adversely affected by electromagnetic interference (EMI) and that it does not emit interference that could affect other equipment.

EMC testing comprises immunity and emissions tests. Immunity tests evaluate the device’s performance amidst electromagnetic interference (EMI). This interference includes radio frequencies and power fluctuations.

Emissions testing is conducted to measure the device’s electromagnetic radiation. This ensures the device does not adversely affect other electronic devices.

These tests are carried out in specialized EMC chambers. These chambers accurately measure emissions and protect the device from external electromagnetic sources.

Ingress Protection (IP Code) Testing

Objective: Determine the device’s level of protection against ingress of solid objects (including dust) and liquids.

IP code testing varies based on the desired protection level. For dust protection, the device is placed in a dust-tight chamber. It is then exposed to circulating dust to simulate a dusty environment.

For liquid protection, the device may be subjected to water sprays or immersion. The objective is to verify that the device’s enclosures prevent the ingress of solids and liquids.

After testing, devices are inspected for any signs of ingress. They are also tested to ensure they still function according to specifications.

Shock and Drop Testing

Objective: Assess the device’s ability to withstand shocks or impacts that could occur during handling, transportation, or use.

Shock and drop testing simulates impacts and shocks from real-world scenarios. Devices are subjected to controlled shocks or drops. This testing mimics potential impacts from handling, transportation, or use.

The aim is to assess the device’s durability. It also checks the device’s ability to maintain operational integrity after impacts.

Devices are inspected for physical damage after testing. Their operational performance is evaluated to ensure no compromise has occurred.

Electrical Safety Testing

Objective: Verify the device’s compliance with safety standards related to electrical hazards.

Electrical safety testing encompasses various tests. These tests ensure the device can safely handle electrical voltages.

Tests include assessing dielectric strength and measuring insulation resistance. They also check for proper grounding. These measures are crucial for preventing electrical accidents and ensuring safety compliance.

High voltages are applied to test dielectric strength. Insulation effectiveness is assessed through resistance measurements. Grounding tests ensure safety from electric shocks.

Operational Testing

Objective: Confirm that the device operates as intended under the conditions it will face during normal use.

Operational testing involves running the device under its normal operational parameters. It simultaneously exposes the device to various test conditions.

This ensures the device withstands individual tests. It also checks that the device performs its intended function under multiple influencing factors.

This phase is crucial for assessing device resilience and reliability. It identifies and addresses potential issues before the device is deployed.
