Vibration testing is a common environmental reliability test for electronics, lighting products, appliances, tools, packaged goods, electromechanical assemblies, and outdoor equipment. It helps identify loosening, abnormal noise, intermittent contact, solder-joint risk, structural cracking, and insufficient packaging protection.
Key Elements in a Test Plan
| Item | Review Focus |
|---|---|
| Test purpose | Separate transport vibration, operating vibration, endurance vibration, random vibration, or buyer-specified scenarios. |
| Sample mounting | Confirm fixture, orientation, cables, accessories, and operating state so mounting does not distort the result. |
| Vibration condition | Define frequency range, acceleration, displacement, sweep rate, random spectrum, axis, and duration. |
| Pre/post checks | Record appearance, structure, fasteners, internal connections, functional checks, and relevant electrical safety review. |
| Failure criteria | Agree how cracking, detachment, functional abnormality, loosened connection, performance drift, and packaging damage will be judged. |
Report Boundary
Vibration test results should be linked to the tested sample, mounting method, vibration parameters, and inspection items. If transport mode, packaging, installation state, or product structure changes, the test condition should be reviewed again.
Green Ark Recommendation
Green Ark (Shenzhen) Certification Co., Ltd. recommends submitting product structure information, packaging method, transport mode, use orientation, and buyer acceptance requirements with samples. For electrical products, functional and safety-related checks before and after vibration are recommended for traceable reliability records.
