The RST 300 Revetest Scratch Tester is a high-performance instrument designed to accurately evaluate coating adhesion, scratch resistance, and surface mechanical properties. It performs fully instrumented scratch tests to determine the critical loads at which coating failure occurs, providing reliable and repeatable characterization of coated materials.
With a maximum test load of 200 N, the system is suitable for a wide range of coating thicknesses and material types. Its automatic critical load detection significantly reduces operator dependence while ensuring objective and reproducible evaluation of coating failure mechanisms. Simultaneous measurement of the coefficient of friction provides additional insight into tribological behavior during scratch testing.
The RST 300 incorporates advanced surface-following technology to compensate for irregular sample geometries, maintaining accurate loading conditions throughout the test. Integrated Panorama synchronized imaging enables direct correlation between mechanical data and visual observations of coating damage, simplifying failure analysis.
In addition to scratch testing, the instrument supports Vickers hardness testing, making it a versatile solution for comprehensive surface characterization. Fully compliant with ASTM C1624 and ISO 20502, the RST 300 is supported by advanced analysis software for automated data processing, reporting, and interpretation.
Designed for industrial quality control and research laboratories, the system is ideal for evaluating PVD and CVD coatings, improving coating development, and ensuring long-term product performance across demanding applications.
