What is dust ingress protection (IP) testing?
Dust ingress testing is classified in international standard IEC 60529 as the degrees of protection provided against the intrusion of dust in electrical enclosures that can cause contamination and corrosion. This type of test can be in the form of:
- Ingress of dust is not totally prevented, but dust shall not penetrate in a sufficient quantity to interfere with satisfactory operation and safety of the product
- No dust whatsoever shall penetrate into product under test
Each test mentioned above is designated by its own IP code.
