What is the IEC standard for vibration testing

Vibration testing is an essential process in various industries to ensure the reliability and performance of products. The International Electrotechnical Commission (IEC) has developed a comprehensive standard for vibration testing, known as the IEC 60068-2-6.

Understanding the IEC 60068-2-6

The IEC 60068-2-6 standard specifically focuses on Sinusoidal Vibration Tests. It provides guidelines for conducting vibration tests, including the requirements for test equipment, test setup, test procedure, and acceptance criteria. The standard aims to simulate real-world vibration environments and evaluate the product's ability to withstand vibrations during transportation, installation, and operation.

Test Conditions and Procedures

The IEC 60068-2-6 standard defines different test conditions and procedures to replicate specific vibration scenarios. These include fixed-frequency tests, swept-frequency tests, and random vibration tests. Each test condition replicates various aspects of vibration, such as single-axis or multi-axis vibration, vertical/horizontal vibration, or rotational vibration. The standard also specifies the duration and amplitude of the vibration for each test scenario.

Acceptance Criteria

For each test scenario, the IEC 60068-2-6 standard sets specific acceptance criteria based on the product's characteristics and application. These criteria typically involve the evaluation of physical damages (e.g., loosened parts or detachment) and functional performance after exposure to vibrations. The standard may also include additional parameters such as resonant frequency, acceleration levels, displacement limits, and other relevant measurements to assess the product's performance.
