Text of the page (random words):
defined by the international electrotechnical commission iec under the international standard iec 60529 1 which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures against intrusion dust accidental contact and water it is published in the european union by the european committee for electrotechnical standardization cenelec as en 60529 the standard aims to provide users with more detailed information than vague marketing terms such as waterproof for example a cellular phone rated at ip67 is dust resistant and can be immersed in 1 meter of freshwater for up to 30 minutes similarly an electrical socket rated ip22 is protected against insertion of fingers and will not become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water ip22 or ip2x are typical minimum requirements for the design of electrical accessories for indoor use 2 the digits indicate conformity with the conditions summarized in the tables below the digit 0 is used where no protection is provided the digit is replaced with the letter x when insufficient data has been gathered to assign a protection level the device can become less capable however it cannot become unsafe there are no hyphens in a standard ip code ipx 8 for example is thus an invalid ip code 3 etymology edit in the original iec 60529 standard from 1976 the letters ip were used without explanation and referred to as characteristic letters 4 in the next editions of the standard 1989 and 1999 respectively the ip is explained to denote international protection on both french and english pages according to the finnish national committee of the iec one possibility is that the abbreviation is a combination of the english word ingress and the french word pénétration which stands for ingress 5 code breakdown edit this table shows what each digit or part of the ip code represents 6 7 code letters first second additional supplementary solid particle protection liquid ingress protection other protections ip 0 6 or x 0 9 or x letter letter by definition required required optional optional first digit solid particle protection edit the first digit indicates the level of protection the enclosure provides against access to hazardous parts e g electrical conductors moving parts and the ingress of solid foreign objects 8 level sized effective against description x unknown x means no data is available to specify a protection rating about this criterion 0 no protection against contact and ingress of objects 1 50 mm 2 0 in 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 0 49 in fingers or similar objects 3 2 5 mm 0 098 in tools thick wires etc 4 1 mm 0 039 in 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 safe 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 airflow second digit liquid ingress protection edit the second digit indicates the level of protection that the enclosure provides against harmful ingress of water 3 the ratings for water ingress are not cumulative beyond ipx6 a device compliant with ipx7 covering water immersion is not necessarily compliant with ipx5 or ipx6 covering exposure to water jets a device that meets both tests is indicated by listing both tests separated by a slash e g ipx5 ipx7 standard ip testing is performed using fresh water protection against other fluids such as salt water oils or solvents is not guaranteed by the rating and requires specific chemical resistance testing level protection against effective against details x unknown x means no data is available to specify a protection rating concerning these criteria 0 none no protection against ingress of water 1 dripping water dripping water vertically falling drops shall have no unsafe effect on the specimen when mounted upright onto a turntable and rotated at 1 rpm test duration 10 minutes water equivalent to 1 mm 0 039 in rainfall per minute 2 dripping water when tilted at 15 vertically dripping water shall have no harmful effect

water equivalent to 3 mm 0 12 in rainfall per minute 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

water under conditions which the manufacturer shall specify however with certain types of equipment it can mean that water can enter but only so that it produces no harmful effects the test depth and duration are expected to be greater than the requirements for ipx7 and other environmental effects may be added such as temperature cycling before immersion test duration agreement with the manufacturer depth specified by the manufacturer generally up to 3 meters 9 8 ft 9 powerful high temperature water jets protected against close range high pressure high temperature spray downs smaller

the ipx9k standard was originally developed for road vehicles especially those that need regular intensive cleaning dump trucks concrete mixers etc but it also finds use in other areas such as food processing machinery and car wash systems it was superseded by iso 20653 2013 road vehicles degrees of protection ip code 12 and complemented by the addition of a level 9 water ingress testing to iec 60529 which includes essentially the same spray test as ipx9k but also includes in figure 10 of the standard a drawing for a test fixture designed to verify the correct water pressure from a metrological verification perspective a critical issue in practical laboratory compliance is the widespread misapplication of standard agricultural spray nozzles instead of certified high precision fan jet nozzles under the required 80 c 176 f high temperature and high pressure environment deviant internal fluid dynamics and non standard orifice profiles fail to achieve the mandatory impact
