How to test the strength and durability of plastic electrical enclosures

Durability test:

1. Temperature cycle testing: waterproof outdoor enclosure are exposed to high and low temperatures and subjected to multiple cycle tests to evaluate their durability under extreme temperature conditions. During testing, the performance changes of the shell at different temperatures, such as deformation, cracks, etc., should be recorded.

2. Humidity cycle test: Plastic enclosures boxes are placed in high and low humidity environments and subjected to multiple cycle tests to evaluate their durability in humid environments. During the test, the performance changes of the shell under different humidity should be recorded, such as corrosion, mildew, etc.

3. Vibration Testing: Vibration testing of enclosures using a vibration table to evaluate their durability in a vibrating environment. When testing, the shell is fixed on a vibration table and gradually increasing vibration force is applied until the shell breaks or becomes loose.
