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.
The IP Code is published by the International Electrotechnical Commission (IEC). The equivalent European standard is EN 60529. The standard aims to provide end-users more detailed information than vague marketing terms such as waterproof. The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no data available to specify a protection rating with regard to one of the criteria, the digit is replaced with the letter X. The digit 0 is used where no protection is provided.
