Overview
IEC 60068-2-86:2024 is a critical international standard developed by the International Electrotechnical Commission (IEC) that specifies the test procedure for vibration testing using multi-exciter and multi-axis methods. This part of IEC 60068 covers environmental testing with the focus on dynamic stresses experienced by components, equipment, and other products-referred to as "specimens"-throughout their lifecycle. While primarily designed for vibration testing, this standard is also applicable to certain shock and transient test scenarios.
The standard provides a comprehensive approach to executing controlled, multi-exciter vibration tests that simulate complex dynamic environments. It addresses both large equipment testing and reliability growth verification for various electrotechnical products, ensuring robustness and durability under operational stresses.
Key Topics
- Multi-exciter and Multi-axis Vibration Testing: The standard details procedures for using multiple exciters across several axes to achieve precise vibration profiles and better emulate real-world conditions.
- Test Apparatus and Control Strategies: Guidelines for configuring test fixtures, managing control systems, and achieving optimal excitation distribution are thoroughly explained to guarantee accuracy and repeatability.
- Test Severities and Tolerances: Specifics on defining vibration intensities and allowable tolerances help maintain test consistency and validate specimen performance.
- Specimen Mounting and Measurement Installation: This covers proper setup to ensure valid data acquisition including positioning of accelerometers and other sensors.
- Pre-conditioning and Functional Testing: The standard stresses the importance of pre-test conditioning, initial performance verification, and ongoing monitoring during and after tests.
- Vibration Response Investigation: Methods for investigating dynamic responses assist in detecting vulnerabilities and improving component design.
- Test Verification and Reporting: IEC 60068-2-86 requires detailed test reports and verification protocols to document procedures, results, and conformity to specified requirements.
- Informative Annexes: Additional guidance covers control system strategies, use of measured data, test tolerance selection, and practical advice for various testing scenarios.
Applications
IEC 60068-2-86:2024 is essential for industries involved in manufacturing and qualifying electrical and electronic equipment subjected to complex vibration environments:
- Aerospace and Defense: Simulation of multi-axis vibrations to qualify avionics and military hardware under operational stresses.
