The Paint Surface Scratch Resistance Tester is a precision instrument designed to evaluate the scratch resistance of painted surfaces, coatings, and automotive finishes. It enables accurate assessment of paint and clearcoat durability, providing reproducible and quantifiable data for coating development, quality control, and comparative testing of surface treatments under controlled laboratory conditions.
Standards
The instrument complies with major international and national standards for coating and paint testing:
ISO 1518 – Paints and varnishes – Determination of scratch resistance
ASTM D5178 – Test method for scratch resistance of coatings using a linear scratch device
ASTM D2197 – Test method for resistance of organic coatings to abrasion
GB/T 23989‑2009 – Determination of scratch resistance of coatings
GB/T 1768‑2006 – Test method for abrasion resistance of paint films
GB/T 6739‑2006 – Paints and varnishes – Pencil hardness test
GB/T 9279‑2007 – Paints and varnishes – Cross-cut test
