The IP ratings’ system was developed to provide general references for the design, materials, usage and safety considerations of electrical enclosures for manufacturing companies in the USA and other countries worldwide.
IP ratings stand for Ingress Protection or International Protection ratings which are from the international standard of EN 60529 (British BS EN 60529:1992, European IEC 60509:1989). As defined in those standards these number defines degrees of protection against the solid and liquid objects.
Solid Objects can be dust, body parts ( hands and fingers), rocks and etc.
Liquid Objects mostly from water but it can be some other type of liquid, it classified by level of intrusion such as
- Dripping water
- Water jets
- Powerful water jets
If you already familiar with IP ratings, you can see our IP rating enclosure products here. However if you are not please read more information below.
IPX PROTECTION CODES
IP 6 5
IP: International Protection or Ingress Protection
6: First Digit: Solid particle protection
5: Second Digit: Liquid particle protection
|ENCLOSURE SIZE EFFECTIVE AGAINST||DESCRIPTION|
|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, slender screws, large ants 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.|
|6||Dust tight||No ingress of dust; complete protection against contact (dust tight). A vacuum must be applied. Test duration of up to 8 hours based on air flow.|
The second digit of the combination
defines the level of protection that the enclosure provides against harmful ingress of water. The ratings for water ingress are not cumulative beyond IPX6. A device which is compliant with IPX7 has characteristic to submerge in water, need not be compliant with IPX5 or IPX6, covering exposure to water jets. A device which meets both tests is indicated by listing both tests separated by a slash, e.g. IPX5/IPX7.
|PROTECTION AGAINST||EFFECTIVE AGAINST|
|1||Dripping water||Dripping water (vertically falling drops) shall have no harmful effect on the specimen when mounted in an upright position onto a turntable and rotated at 1 RPM.|
|2||Dripping water when tilted at 15°||Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle of 15° from its normal position. A total of four positions are tested within two axes.|
|3||Spraying water||Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect, utilizing either: a) an oscillating fixture, or b) A spray nozzle with a counterbalanced shield.
Test a) is conducted for 5 minutes, then repeated with the specimen rotated horizontally by 90° for the second 5-minute test. Test b) is conducted (with shield in place) for 5 minutes minimum.
|4||Splashing of water||Water splashing against the enclosure from any direction shall have no harmful effect, utilizing either: a) an oscillating fixture, or b) A spray nozzle with no shield.
Test a) is conducted for 10 minutes. Test b) is conducted (without shield) for 5 minutes minimum.
|5||Water jets||Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects.|
|6||Powerful water jets||Water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction shall have no harmful effects.|
|6K||Powerful water jets with increased pressure||Water projected in powerful jets (6.3 mm nozzle) against the enclosure from any direction, under elevated pressure, shall have no harmful effects. Found in DIN 40050, and not IEC 60529.|
|7||Immersion, up to 1 m depth||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, 1 m or more depth||The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. The test depth and duration is expected to be greater than the requirements for IPx7, and other environmental effects may be added, such as temperature cycling before immersion.|
|9K||Powerful high temperature water jets||Protected against close-range high pressure, high temperature spray downs.
Smaller specimens rotate slowly on a turntable, from 4 specific angles. Larger specimens are mounted upright, no turntable required, and are tested freehand for at least 3 minutes at distance of 0.15–0.2 m.
There are specific requirements for the nozzle used for the testing.
This test is identified as IPx9 in IEC 60529.
Furthermore, extra special letters can be appended behind 2 digits talking above to provide additional information related to the protection of the device.
|H||High voltage device|
|M||Device moving during water test|
|S||Device standing still during water test|
