The International Organization for Standardization (ISO) has published new standards intended for paints and varnishes.
ISO 7784-2:2016 Paints and Varnishes -- Determination of Resistance to Abrasion -- Part 2: Method with Abrasive Rubber Wheels and Rotating Test Specimen. The standard provides a method for determining the resistance to abrasion of coatings, for which two loaded, freely rotatable but eccentrically arranged abrasive rubber wheels affect the coating of the rotating test specimen.
ISO 7784-3:2016 Paints and Varnishes -- Determination of Resistance to Abrasion -- Part 3: Method with Abrasive-Paper Covered Wheel and Linearly Reciprocating Test Specimen. The standard provides a method for determining the resistance to abrasion of coatings, for which a loaded, rigid abrasive-paper covered wheel affects the coating of the linearly reciprocating test specimen.
The standards were published March 15, 2016.
