What is Dustproof Level Testing?

Dustproof testing is used to evaluate the ability of electrical and electronic products, automotive and motorcycle components, and seals to prevent dust ingress into enclosures and seals under sandy or dusty conditions. It determines the effects of airborne dust on products and assesses their performance during use, storage, and transportation in dusty environments.

Dustproof Levels:  

1. Resistant to solid objects larger than 50mm, e.g., accidental touch by a hand.  

2. Resistant to solid objects with a diameter larger than 12mm and a length not exceeding 80mm, e.g., fingers.  

3. Resistant to solid objects larger than 2.5mm, e.g., tools or metal wires.  

4. Resistant to solid objects larger than 1.0mm, e.g., fine metal wires.  

5. Dust-protected: Limited ingress (no harmfUL accumulation).  

6. Dust-tight: Dust cannot enter, fully sealed against dust.  

Testing Standards:  

Dustproof testing standards reference GB/T 4208, IEC 60529, etc.
