IP classification test

The IP Code, International Protection Marking, sometimes referred as Ingress Protection Marking, classifies and rates the degree of protection provided against intrusion (body parts such as hands and fingers), dust, accidental contact, and water to mechanical casings and electrical enclosures. 

Water and dust tightness is an essential part of a product’s life cycle. By testing your product you make sure that the product meets the definition and withstands the ambient conditions in use. The first digit of the IP code identifies the dust tightness or foreign object, such as a hand or finger. The second number defines the watertightness. Example of IP markings: The IP67 marking means that the product is completely dustproof and can withstand immersion in water to a depth of one meter for 30 minutes. After the tests the functions of the product is tested and internal parts of the product are checked for water and dust penetration. The IP standard is published by the International Electrotechnical Commission (IEC) and the corresponding European standard is EN 60529.
