w w w. i ei wor l d.c o m About IEI-2017-V10 contact, and water in electrical enclosures. It consists of the letters IP followed by two digits and an optional letter. The digits indicate conformity with the conditions summarized in the tables below. First digit Level Object size protected against Effective against 0 - No protection against contact and ingress of objects 1 >50 mm Any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part 2 >12.5 mm Fingers or similar objects 3 >2.5 mm Tools, thick wires, etc. 4 >1 mm Most wires, screws, etc. 5 dust protected Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact 6 dust tight No ingress of dust; complete protection against contact hazardous parts Ø50mm Ø12.5mm 2.5mm 1mm IEI follows standard testing procedures (UL 50) to design ruggedized LCD products with high reliability. We mainly provide IP environment applications. Second digit Protection of the equipment inside the enclosure against harmful ingress of water. Level Protected against Details 0 - not protected — 1 dripping water Dripping water (vertically falling drops) shall have no harmful effect 2 dripping water when tilted up to 15° Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position 3 spraying water Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect 4 splashing water Water splashing against the enclosure from any direction shall have no harmful effect 5 water jets Water projected by a nozzle against enclosure from any direction shall have no harmful effects 6 powerful water jets Water projected in powerful jets against the enclosure from any direction shall have no harmful effects 7 immersion up to 1 m Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion) 8 immersion beyond 1 m The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer 9K Powerful high temperature water jets Protected against close-range high pressure, high temperature spray downs.Test duration: 30 seconds in each of 4 angles ,Water temperature: 80 °C 90º 60º 0º IEI’s LCD products are front sealed and tested in the certified house chamber under UL’s Witnessed Test Data Program (WTDP). IP 64 IP 65 IP 66 / UL 50 IP 67 IP 69K Chamber strickly approved by Underwriters Laboratories Inc. IEI's in-house water resistance chamber is approved by the UL organization commonly recognized in North America.
