The interpretation of results is based on the comparison of pre-test, during-test, and post-test conditions of the specimen. Acceptable performance implies that the test item can hold up to the environmental strain that is enforced without unacceptable deterioration. Any kind of failure, like cracking, corrosion, electrical failure, or failure of ability, is an indication of environmental susceptibility. Interpretation is also focused on stress response behaviour interpretation and not on pass-fail certification.
IEC 60068 is regularly used in conjunction with military standards, e.g., MIL-STD-810 of defence equipment and IEC 60529 of ingress protection. The environmental test methods of ASTM could also be applied at the material level to supplement the system-level environmental testing.
IEC 60068 Applications in Industry
The test method is commonly applied in electronics, automotive, aerospace, telecommunications, medical devices and in the production of industrial equipment. It aids the qualification of the product, design assurance, reliability testing, and adherence to the international regulatory and customer requirements.
IEC 60068 Materials Commonly Tested
Some typical examples of materials and products that are tested are electronic assemblies, printed circuit boards, sensors, connectors, enclosures, cables, mechanical parts, and packaged equipment. Structural and functional materials are both assessed.
IEC 60068 Common Challenges and Troubleshooting
Among the pitfalls, there are wrong choices of test severity, wrong specimen set-up, and impractical environment profiles. Troubleshooting means adjusting test conditions to the actual service conditions, proper instrumentation, and checking that the proper IEC 60068 method is being used.
IEC 60068 Safety and Best Practices
The training of personnel and calibrated equipment must be used to carry out environmental testing. Special precautions are also needed when testing in high temperatures, high levels of vibration, changes in pressure, or mechanical shock. Association of clear documentation, controlled sequencing, and repeatable procedures enhances the reliability of data and the validity of tests.
Importance of IEC 60068 Test Standard
IEC 60068 provides a common set of environmental testing standards worldwide, enabling comparable assessments of durability and reliability across industries. The standard helps to create strong product design, fewer field failures, and better lifecycle performance by being able to find the weaknesses of the environmental conditions at an early stage of product development and testing.
