Vibration(Sinusoidal) /Broadband Test

This test is intended to identify any mechanical defects and/or degradation of the specimens’ specified performance. Using this data in conjunction with the applicable specification, the specimens’ acceptability will be determined. The test method is sometimes used to demonstrate the mechanical strength of specimens and/or to examine their dynamic behavior. Component categorization can also be done by choosing severity from the list provided in the test.

Sinusoidal Vibration Test:

  • sinusoidal vibration for the assessment of a device or component’s ability to withstand vibration stresses.
  • It outlines procedures for subjecting devices to sinusoidal vibration in one or more axes, at specified frequencies and amplitudes.
  • It’s often used to determine resonant frequencies, structural weaknesses, and the response of equipment to specific frequencies.

The Vibration sinusoidal Test IEC BS EN 60068-2-6 is a standard that specifies test procedures and test levels.

Broadband Vibration Test:

  • broadband random or non-sinusoidal vibration to evaluate the robustness and performance of equipment or devices.
  • It includes methods for subjecting devices to a wider range of frequencies simultaneously or sequentially within a defined frequency band.

The Vibration broadband Test IEC BS EN 60068-2-64 is a standard that specifies test procedures and test levels.
