[[File:09584jfCalumpit Pulilan Bulacan Landmarksfvf 17.jpg|thumb|IP65 LED lamp]]The '''IP code''' or '''ingressIngress protectionProtection code''' indicates how well a device is protected against water and dust. It is defined by the [[International Electrotechnical Commission]]&nbsp;(IEC) under the [[international standard]] IEC 60529<ref>{{Cite web |title=IEC 60529:1989+AMD1:1999+AMD2:2013 CSV {{!}} IEC Webstore {{!}} water management, smart city, rural electrification |url=https://webstore.iec.ch/publication/2452 |access-date=2024-05-08 |website=webstore.iec.ch}}</ref> which classifies and provides a guideline to the degree of protection provided by mechanical casings and [[electrical enclosures]] against intrusion, [[dust]], accidental contact, and [[waterproofing|water]]. It is published in the European Union by the [[European Committee for Electrotechnical Standardization]]&nbsp;(CENELEC) as EN&nbsp;60529.
 
The standard aims to provide users 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.<ref>{{Cite web |title=IP Rating - Ingress Protection Explained {{!}} Tansun |url=https://www.tansun.com/gb_en/technical/technical-ip-rating.html |access-date=2024-05-08 |website=www.tansun.com}}</ref>
 
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.<ref name="NE Laser" />
 
== Etymology ==
In the original IEC 60529 standard from year 1976, the letters IP are used without providing an explanation, and referred as "characteristic letters".<ref>{{Cite book |title=IEC Publication 529: Classification des degrés de protection procurés par les enveloppes – Classification of degrees of protection provided by enclosures |publisher=[[International Electrotechnical Commission]] |year=1976 |edition=1st}}</ref> In the next editions of the standard, from years 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 English word ingress and French word ''pénétration'' which stands for ingress, but finding the correct answer would require doing a historical study on the 1970's standardization, which is difficult because the experts preparing the original standards are likely retired or deceased.<ref>{{Cite web |title=SESKO: Frequently asked questions (in Finnish) |url=https://sesko.fi/yhteystiedot/usein-kysytyt-kysymykset/ |access-date=2023-08-22 |website=sesko.fi}}</ref>

===First digit: Solid particle protection===
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.<ref name="IEC 60529">{{cite book |title=IEC 60529 - Degrees of protection provided by enclosures (IP Code) |series=International standard |author=International Electrotechnical Commission |edition=2.2 |year=2013 |page=21 |isbn=9782832210864 |oclc=864643678|ref={{harvid|IEC 60529|2013}} }}</ref>

===Second digit: Liquid ingress protection===
The second digit indicates the level of protection that the enclosure provides against harmful ingress of water.<ref name="NE Laser">{{citation|title=Ingress Protection: The System of Tests and Meaning of Codes|url=http://www.ce-mag.com/archive/06/ARG/bisenius.htm|archive-url=https://web.archive.org/web/20130522115323/http://www.ce-mag.com/archive/06/ARG/bisenius.htm|archive-date=2013-05-22|url-status=dead}}.<!-- http://www.webcitation.org/6DGYoRMwp?url=http://www.ce-mag.com/archive/06/ARG/bisenius.htm --></ref>
 
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.
IPX5/IPX7.

== IP69KIPx9K and IPx9 ==
[[Deutsches Institut für Normung|DIN]] 40050-9 extended the newer IEC 60529 rating system with an '''IP69K''' rating for high-pressure, high-temperature wash-down applications.<ref>{{citation | title = [[DIN]] 40050-9: ''Straßenfahrzeuge; IP-Schutzarten; Schutz gegen Fremdkörper, Wasser und Berühren; Elektrische Ausrüstung'' [Road vehicles; degrees of protection (IP-code); protection against foreign objects, water and impact; electrical equipment] | date = May 1993}}. An English translation of the German original is available from DIN.</ref> Enclosures conforming with ISO 20653:2013 must notbe only beboth dust-tight (IP6X), but alsoand able to withstand high-pressure and steam cleaning.
 
The IP69KIPx9K 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),<ref>ISO 20653:2013 Road Vehicles-Degrees of protection (IP code) Protection of electrical equipment against foreign objects, water and access</ref> and complemented by the addition of a level 9 water ingress testing to IEC 60529, which includes essentially the same spray test as IP69KIPx9K, but also includes, in Figure 10 of the standard, a drawing for a test fixture designed to verify the correct water pressure.
