What Is IP69K — ISO 20653?
IP69K is a protection level against washing with a high-pressure, high-temperature water jet. The test is performed by holding the specimen, on a rotating table, close to a hot-water jet from specified angles. The level is defined in ISO 20653.
Purpose of IP69K — ISO 20653
The purpose is to show that equipment exposed to pressure washing can withstand this process without damage. Food production lines and heavy-duty vehicles are regularly cleaned with high-pressure hot water; ordinary IP levels do not represent this stress.
Which Products Is IP69K — ISO 20653 Applied To?
- Food-processing machinery and hygienic equipment
- Heavy-duty vehicles and construction machinery
- Vehicle exterior-trim sensors and cameras
- Agricultural machinery
- Field-type electrical equipment

- High-pressure hot-water unit
- Flat-jet nozzle conforming to the standard
- Pressure, temperature and flow-rate measurement equipment
Sample Requirements for IP69K — ISO 20653
- The specimen must be ready for sale and assembled
- Cable entries, gaskets and covers must be as in real use
- It must be openable for internal inspection after the test
- The specimen must be sized to fit on the turntable
Duration of IP69K — ISO 20653
The test itself is short; preparation, testing and internal inspection are generally completed within the same day.
IP69K — ISO 20653 Procedure
- 1The specimen is inspected and its initial condition is recorded.
- 2The specimen is placed on the turntable at the height defined in the standard.
- 3The water temperature and pressure are set and verified.
- 4The jet is applied in turn from each defined angle while the specimen is rotated.
- 5At the end of the test the specimen's exterior is dried.
- 6The enclosure is opened to check for water ingress.
- 7Functional and electrical checks are made.
IP69K — ISO 20653 Acceptance Criteria
The acceptance criterion comes from the product standard or the customer's specification; the general expectation is that any water ingress does not impair the product's function or electrical safety.
Evaluation of Results
IP69K does not substitute for IPX7 or IPX8; it represents a different stress. The position of gaskets relative to the jet direction is the main design factor determining the result.
IP69K — ISO 20653 Report
- Sample description, serial number and configuration
- Applied standard and year of printing
- Selected intensity level and basis for the level
- Experimental setup and measurement points
- Functional checks performed during the experiment
- Observations, measurement results and photographs
- A statement that the result applies only to the specimen submitted for testing
Accreditation
EUROLAB holds internationally recognised accreditation obtained from accreditation bodies party to the IAF and ILAC multilateral recognition arrangements, under ISO/IEC 17025 for laboratory testing, ISO/IEC 17020 for inspection and surveillance, and ISO/IEC 17021-1 and ISO/IEC 17065 for system and product certification. This chain ensures the reports and certificates issued are accepted worldwide.
Whether this test can be offered within accredited scope depends on your product and the standard applied; since accreditation is method-based, the scope is confirmed in writing at the quotation stage.

Standard-Based Tests — What Does This Group of Pages Cover?
The section below describes the field that the IP69K test belongs to; the conditions and acceptance criteria of this particular test are given in the sections above. The scope specific to your product is confirmed in writing at the quotation stage.
Standard-based tests are test pages whose address comes from a standard number. What the user is looking for is often not the name of the test but the code written in their specification: not "salt spray test" but "ASTM B117", not "drop test" but "IEC 60068-2-31", not "vibration" but "MIL-STD-810 Method 514".
This preference reflects the reality in the field. An engineer sees a code in the specification received from a customer and searches for that code; they do not need to know the name of the test. The code is the identity of the test and distinguishes the different adoptions of the same test by different bodies.
This group addresses the different adoptions of the SAME TEST separately. The same physical phenomenon may be published under different numbers by ISO, ASTM, EN, IEC, DIN and JIS. Even where the numbers are the same (as with ISO 6892-1 and EN ISO 6892-1), specimen preparation, conditions, calculation details and reporting may differ; adoptions may carry national annexes. The code written in the specification therefore governs, and "similar" is not accepted.
Searching at code level meets a different need from searching at scope level. A user searching for "corrosion testing" wants to learn about the field; a user searching for "ASTM B117" has a specification in hand and wants to know the feasibility, duration and price of that test. Two different intents require two different page structures.
The page for a code describes the scope of that code, the test field it belongs to, the product groups in which it is required and how it differs from neighbouring codes. Test conditions, durations and acceptance criteria are NOT CARRIED: these are defined in the copyrighted text of the standard and in the product specification. This boundary is a deliberate choice; a wrong duration or acceptance criterion means directly incorrect work.
Different parts of the same code and different adoptions of the same number are linked between pages. A user searching for IEC 60335 also sees 60335-2-40; a user searching for ISO 6892-1 also sees the EN ISO 6892-1 and DIN EN ISO 6892-1 adoptions. These links are derived from the number of the code rather than written by hand.
The edition year is NOT CARRIED in the library. It is held as "ASTM D638" rather than "ASTM D638-22", because the edition in force changes over time and the address of the page should not age with the edition. If a year is stated in your specification, that edition governs; if not, the most current edition is applied.
Method groups in this field
Searching by code
Direct search for the code written in the specification; it is found in the library with its code, scope title and issuing body.
Searching by scope title
A test whose code is not known is searched by its subject; a search for "salt spray" brings up the related codes.
Series and part relationships
The other parts of the same series are shown, derived from the number of the code.
Adoption relationships
Different bodies' adoptions of the same number are matched; the claim is kept limited to "the same number".
Superseded codes
Withdrawn codes are not held in the library but, when searched for, the user is directed to the counterpart in force.
Commonly confused in this field
- Different adoptions of the same number are not identical texts; they may carry national annexes.
- The code written in the specification governs; a technically similar code cannot be substituted.
- If an edition year is stated, that edition is applied; the most current edition is not automatically accepted.
- A code page carries no test conditions or acceptance criteria; these are in the copyrighted text of the standard and in the product specification.
- A part code (for example -2-40) may not be sufficient on its own; the general part of the series is applied as well.
Which decisions these results support
- Matching the code written in the specification to the correct laboratory scope
- Distinguishing between equivalent adoptions
- Clarifying the scope and edition at the quotation stage
- Finding the current counterpart of withdrawn codes

Frequently Asked Questions About IP69K — ISO 20653
Does IP69K cover all water tests?
No. It represents high-pressure washing; it does not demonstrate immersion protection. For an immersion declaration, IPX7/IPX8 must be tested separately.
Why is there a letter K?
The code carries this additional letter because the level was first defined in a German vehicle standard (DIN 40050-9); it now falls under ISO 20653.
