| IP1x | A sphere (Ø 50mm) is pressed against all the openings of the enclosure with the compressive force 50 N. Acceptance conditions for IP1X are met if the sphere does not fully penetrate into the enclosure and that satisfactory distances are kept to dangerous live and moving parts. | |||
| IP2x | A standard test finger (Ø 12 mm) is pressed against all the openings of the enclosure with a compressive force of 10 N and a sphere (Ø 12.5 mm) is pressed against all the openings of the enclosure with a compressive force of 30 N. The acceptance conditions for IP2x are met if the sphere does not fully penetrate the enclosure and that satisfactory distance from the test finger is kept to dangerous live and moving parts respectively. | |||
| IP3x | A standard test probe (steel wire Ø 2.5 mm) is pressed against all the openings of the enclosure with a compressive force of 3 N. Acceptance conditions for IP3X are met if the steel wire does not penetrate the enclosure. | |||
| IP4x | A standard test probe (steel wire Ø 1 mm) is pressed against all the openings of the enclosure with a compressive force of 1 N. Acceptance conditions for IP4X are met if the steel wire does not penetrate the enclosure. | |||
| IP5x | In a dust chamber, the enclosure is exposed to fine-grained circulating talcum powder for a period of 2-8 hours (the conditions for the specific enclosure control the test time). The test is carried out with a maximum of 20 mbar negative pressure inside the enclosure and with a maximum of 60 volumes / hour air flow. If specific product standards allow, testing is carried out without vacuum for 8 hours. In addition to the dust test, a steel wire (Ø 1 mm) is pressed against all the openings of the housing with a compressive force of 1 N. The acceptance conditions for IP5x are met unless dust has penetrated into such quantity or in such a place that the material's satisfactory operation or the safety is compromised, and that satisfactory distances from the wire are kept to dangerous live and moving parts respectively. | |||
| IP6x | In a dust chamber, the enclosure is exposed to fine-grained circulating talcum powder for a period of 2-8 hours (the conditions for the specific enclosure control the test time). The test is carried out with a maximum of 20 mbar negative pressure inside the enclosure and with a maximum of 60 volumes / hour air flow. In addition to the dust test, a steel wire (Ø 1 mm) is pressed against all the openings of the housing with a compressive force of 1 N. The acceptance conditions for IP6x are met if no dust has penetrated into the housing and that satisfactory distance from the wire is kept to dangerous live and moving parts. | |||

| IPx0 | No protection |
| IPx1 | The enclosure is exposed to dripping water for 10 minutes at 1 mm/min water flow. The acceptance conditions for IPx1 are fulfilled if no water has penetrated in such quantity or in such a way that the satisfactory operation of the equipment is affected or the safety is compromised. |
| IPx2 | The enclosure is exposed to dripping water for 4 x 2.5 minutes with 3 mm/min water flow. The enclosure is tested in four (4) fixed incline positions, 15 ° from normal positioning. The acceptance conditions for IPx2 are fulfilled if no water has penetrated in such quantity or in such a way that the satisfactory operation of the equipment is affected or the safety is compromised. |
| IPx3 | The casing is exposed to soothing water for 10 minutes, using a bow arc where each nozzle provides 0.07 l/minute water flow. Alternatively, standard spreader nozzle with 10 l / minute water flow is used. If a nozzle is used, the exposure time is 1 minute / m 2 , but at least 5 minutes. Regardless of the test equipment, water spraying is limited to ± 60 ° from the vertical. The acceptance conditions for IPx3 are fulfilled if no water has penetrated in such quantity or in such a way that the satisfactory operation of the equipment is affected or the safety is compromised. |
| IPx4 | The casing is exposed to soothing water for 10 minutes, using a bow arc where each nozzle provides 0.07 l/minute water flow. Alternatively, standard spreader nozzle with 10 l / minute water flow is used. If a nozzle is used, the exposure time is 1 minute / m 2 , but at least 5 minutes. Water spraying is performed from all directions on the surfaces of the housing. The acceptance conditions for IPx4 are fulfilled if no water has penetrated in such quantity or in such a way that the satisfactory operation of the equipment is affected or the safety is compromised. |
| IPx5 | The enclosure is sprayed with a jet of water through a nozzle (Ø 6.3 mm) at a distance of 2.5 - 3 meters from the specimen. The water flow is 12.5 l/minute and the duration is 1 min / m 2 , but at least 3 minutes. The acceptance conditions for IPx5 are fulfilled if no water has penetrated in such quantity or in such a way that the satisfactory operation of the equipment is affected or the safety is compromised. |
| IPx6 | The enclosure is sprayed with a jet of water through a nozzle (Ø 12.5 mm) at a distance of 2.5 - 3 meters from the test object. The water flow is 100 l / minute and the duration is 1 min / m 2 , but at least 3 minutes. The acceptance conditions for IPx6 are fulfilled if no water has penetrated in such quantity or in such a way that the satisfactory operation of the equipment is affected or the safety is compromised. |
| IPx7 | The enclosure is immersed in a water container to a (1) meter water depth and remains there for 30 minutes. The acceptance conditions for IPx7 are fulfilled if no water has penetrated in such quantity or in such a way that the satisfactory operation of the equipment is affected or the safety is compromised. |
| IPx8 | The enclosure is immersed in a water container and tested with water pressure and duration according to the customer's specification. The acceptance conditions for IPx8 are fulfilled if no water has penetrated in such quantity or place that the material's satisfactory operation is affected or the safety is compromised. |
IP is an abbreviation of "International Protection" but is also sometimes interpreted as "Ingress Protection"
Also goes under the name enclosure class is a classification to which level an electrical appliance is protected for touch and penetration and how well the appliance is protected against water ingress.
