Application
This tester is widely applied in durability and damage resistance evaluation for materials exposed to gravel impact during actual service conditions, especially in the automotive and coating industries. Typical applications include:
External coating cohesion failure testing
Interlayer adhesion failure testing of multilayer coating systems
Brittleness thickness evaluation of hard glass materials
Optimization of coating thickness for anti-spall performance
Impact, spall resistance, and wear resistance testing of plastics and glass
Stone-chip resistance testing for automotive exterior and interior components
Tested products may include automotive body coatings, plastic trim parts, glass panels, protective coatings, and other exterior decorative or functional materials.

Test Procedures
Power on the equipment and allow it to preheat to the preset temperature (approximately 15–30 minutes).
Place the prepared sample into the test chamber and securely close the chamber door.
Start the test program; the system automatically controls temperature, pressure release, and aggregate impact.
Monitor temperature and pressure parameters via the control panel to ensure stable operation throughout the test.
