Waterproof / Waterresistant IP Ratings
IP65 Water resistant
IP66 Water resistant against powerful jets
IP67 Protected against complete temporary water submersion
A fixture with an IP rating of 65 is protected against multi-directional, low-pressure water jets. In order to pass testing and achieve an IP65 rating, fixtures must be able to withstand water projected by a 0.25-inch nozzle. To achieve satisfactory results, this test must be run for a minimum of fifteen minutes, with the water source placed three yards from the fixture. Additionally, the water pressure must be 30 kPa with water volume of 3.3 gallons per minute.
An IP66 rated fixture is protected against multi-directional, high-pressure water jets. To pass IP66 testing, the fixture must be able to withstand water projected from 0.50-inch nozzle, multi-directional, high-pressure jets. This test must be run for a minimum of three minutes, at a distance of three yards, with a water volume of 26.4 gallons per minute and a pressure of 100 kPa.
A fixture rated at IP67 is protected from water immersion between 5.9 inches and 39.37 inches. To pass IP67 testing, the fixture must not permit ingress of harmful quantities of water when fully immersed. There must be at least 5.9 inches of water above the fixture for the test to be valid.
