An IP code, short for International Protection Marking, classifies and rates the degree of protection provided against intrusion of dust and water into an electrical enclosure. An example would be IP67. The first number, 6, denotes its dust protection rating. The second number, 7, denotes its water protection rating. A full list of the meaning of each code is shown below. UL does not recognize IP ratings and if a Hatch product does not have an IP rating on the specification sheet, it does not have an IP rating. In most instances, LED drivers do not require an IP rating because they are typically inside of a fixture, in which case the fixture would be IP rated and therefore the driver would be protected.
