== IPx9K 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 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 It was superseded by ISO 20653:2013 Road Vehicles-Degrees of protection (IP code),<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 IPx9K, but also includes, in Figure 10 of the standard, a drawing for a test fixture designed to verify the correct water pressure.
