Plastic electrical boxes are a common product in our daily lives. They are usually used to protect and store various electronic devices. However, since the quality of plastic junction box on the market varies, it’s important to know how to test their durability.

Here are some steps for testing the durability of Plastic electrical boxes:

1. Visual inspection: First, you need to perform a visual inspection of the box. Check the box for cracks, chips, or other obvious damage. In addition, check whether the color of the box is even and whether there is any fading or spots.

2. Material test: The Plastic electrical boxes is usually polyethylene, polypropylene or polyvinyl chloride, etc. You can test a small piece of plastic by lighting it on fire. If the plastic is left with black lumps after burning, it’s probably high-density polyethylene; if it’s white ash, it’s probably low-density polyethylene.

3. Pressure resistance test: Place the plastic enclosure on two flat surfaces, and then apply a certain amount of pressure on it. If the box does not deform or crack under pressure, then it has good compression resistance.

4. Impact resistance test: Drop a heavy object from a certain height and hit it on the box. If the box hasn’t been smashed, then its impact resistance is pretty good.

5. Waterproof test: Put the box into the water and observe it for a period of time to see if it will seep. If the box does not seep in water, then it is very waterproof.

6. Temperature test: Place the box in a high or low temperature environment and observe it for a period of time to see if it will deform or crack. If a box retains its shape and performs well under extreme temperatures, then its durability is good.

Through the above test, you can know how durable the box is. However, these tests can only provide a rough judgment. If you need more precise data, you may need to seek help from a professional testing agency.
