The ISO 20566 Wheel Scratch Resistance Laboratory Car Wash Simulator is a precision testing instrument designed to evaluate the scratch resistance of automotive coating systems under controlled laboratory conditions. It replicates real-world car wash operations to provide consistent, repeatable, and quantifiable results on paint and clearcoat durability, helping to ensure coating performance meets industry and international standards.
The laboratory car wash simulator is primarily used to assess the scratch resistance of automotive coatings. Typical applications include:
Evaluation of automotive exterior paint and clearcoat systems
Quality control of vehicle coatings in research and development laboratories
Performance testing of aftermarket protective coatings
Comparative testing of different paint formulations or surface treatments
Specific testing product: ISO 20566 Wheel Scratch Resistance Laboratory Car Wash Simulator
The simulator is designed to comply with multiple international and industry standards:
PV 3.3.3 – Scratch resistance test specification for automotive interior surfaces
ISO 20566:2020 – Paints and varnishes – Determination of scratch resistance of coating systems by laboratory car wash
MBN 10494-5 – Scratch resistance testing of automotive interior materials, Part 5

Cleaning and maintenance tools
Standardized washing suspension solution
Sample Preparation:
Select a representative test panel in accordance with ISO 15528.
Inspect and prepare each sample according to ISO 1513.
Test Panel Setup:
Ensure the test panel is flat, deformation-free, and conforms to required dimensions.
Panel thickness should be 0.5–5 mm; for other thicknesses, adjust the brush depth and angle via the panel holder.
Testing Procedure:
Conduct the test at room temperature (20–30°C).
Determine the testing area for each device using a control panel, especially after replacing the electric brush. The gloss difference between the test area and the scratch region should not exceed 15 gloss units.
Exclude evaluation within 5 cm from panel edges or along at least 3 cm parallel to the panel movement direction.
Before testing, run the simulator without any test panels for 10 wash cycles (10 bi-directional operations) to evenly distribute the washing suspension and ensure uniform thickness across test areas.
Maintenance Information
Regularly clean brushes and nozzles to prevent residue build-up
Verify rotation speed, feed rate, and spray flow before each test
Replace worn bristles and check brush alignment periodically
Calibrate control system according to manufacturer recommendations
