Laboratory Automotive Wash Scrub Test Bench
Laboratory Automotive Wash Scrub Test Bench is a specialized testing apparatus designed to simulate the automated vehicle washing process under laboratory conditions. Through a controlled system of brushing, water spraying, and cleaning solution circulation, it subjects automotive coating systems to repeated scrub washing. This evaluates the coating system's scratch resistance and appearance retention capabilities under actual car wash conditions. The equipment provides reliable experimental evidence for coating durability, appearance changes, and quality stability.
Application
The Laboratory Automotive Wash Friction Test Bench is widely applied in the following fields, covering standard testing requirements comparable to peer equipment:
- Automotive body and component coating systems
- OEM and refinish paint systems
- Automotive exterior plastic and trim components
Automotive clear coat and pigmented paint systems
Industrial coating scrub resistance evaluation
New material and process coating R&D validation
Coating durability and appearance degradation studies
Automotive OEM and parts supplier laboratories
Third-party testing agencies and research institutions
Standards
The equipment meets the testing requirements of the following relevant standards, presented in logical sequence according to GB/ISO/international standards:
BS ISO 20566 Paints and varnishes — Determination of scratch resistance of coating systems by laboratory car wash
ISO 20566:2021 Paints and varnishes — Determination of scratch resistance of coating systems by laboratory car wash
ISO 13076 Visual assessment of the appearance of coated surfaces
ISO 2813 Determination of gloss of coatings
ISO 13803 Determination of haze of coatings
ISO 7724 Color measurement and color difference evaluation
