The IP69K test specification
was initially developed for enclosures designed to protect against ingress of dust and harmful effects of high-pressure jet steam cleaning
, in road vehicles.
German standard DIN 40050-9 extends the IEC 60529 rating system described above with an IP69K rating for high-pressure, high-temperature wash-down applications.
The IP69K to DIN40 050-9/5.93 lists the protection category test consisting of the following parameters:
pressure up to 100 bar; 14-16 litres per minute flow rate;
- Temperature up to 80̊C; distance min 100 to max 150mm.
- Duration of the test calls for 4 directions and test jet time of 30 sec each
- At the angles of 0̊, 30̊, 60̊ and finally 90̊.
- To achieve the 4 directional test, the test object is placed on a rotating turntable.

North American NEMA Enclosure Types:
NEMA 250, Enclosures for Electrical Equipment
(1000 Volts Maximum http://www.nema.org/prod/be/enclosur...sure_Types.pdf
A few applicable NEMA code designations for electrical enclosures:
NEMA TYPE 3R
Rainproof and Sleet- (Ice-) Resistant-Outdoor - Type 3R enclosures are intended for use outdoors to protect the enclosed equipment
against rain and meet the requirements of Underwriters' Laboratories, Inc., Publication No. UL 508, applying to "Rainproof Enclosures." They are not dust-, snow-, nor sleet (ice-) proof. They shall have conduit hub or equivalent provision for watertight connection at the conduit entrance when the conduit enters at a level higher than the lowest live part, provision for locking, and provision for drainage. When completely and properly installed, these enclosures shall prevent the entrance of rain at a level higher than the lowest live part.
NEMA TYPE 4
Watertight and Dusttight-Indoor and Outdoor - Type 4 enclosures are intended for use indoors or outdoors to protect the enclosed equipment against splashing water, seepage of water, failing or hose directed water, and severe external condensation
. They are sleet-resistant but not sleet- (ice-) proof. They shall have conduit hubs or equivalent provision for watertight connection at the conduit entrance and mounting means external to the equipment cavity.
NEMA TYPE 6
Watertight, Dusttight and Sleet-( Ice-) Resistant-Indoor and Outdoor - Type 6 enclosures are intended for use indoors or outdoors where occasional submersion is encountered. They shall protect the enclosed equipment against a static head
of water of 6 feet for 30 minutes, dust, splashing or external condensation
of non corrosive liquids, falling or hose-directed water, lint and seepage. They are not sleet- (ice-) proof. They shall have conduit hubs or equivalent provision for watertight-connection at the conduit entrance and mounting means external to the equipment cavity.
