ISO 7840 establishes a standardized method for evaluating scratch and abrasion resistance of elastomers and plastics using a normalized testing apparatus. The procedure involves rubbing the material surface with a standardized stylus under controlled load while measuring the depth and width of resulting scratches. Applicable to rubbers, thermoplastic elastomers, and plastic materials, this standard enables objective assessment of surface durability and wear resistance under reproducible conditions, ensuring consistent and comparable results across different laboratories and manufacturers.
