These tests demonstrate that the equipment complies with the applicable equipment performance standards (including durability requirements) when subjected to vibration levels specified for the appropriate installation.
Category Definitions:
The appropriate category (or categories) selected from the categories defined below should be based upon the level of assurance required for the equipment demonstration of performance.
For equipment on fixed wing aircraft, either a standard or a robust vibration test may be performed. The need to do the high level short duration test is dependent upon the equipment performance requirements. For equipment on helicopters, only a robust test may be performed.
Standard Vibration Test (Category S)
Robust Vibration Test (Categories R, U, U2)
High-Level, Short Duration Vibration Test (Categories H, Z)
