ISO 7784-1 is the ISO standard that specifies a method for determining the resistance of coatings to abrasion. The current edition is ISO 7784-1:2023, which replaced ISO 7784-1:2016.
In this method, two loaded, freely rotating and eccentrically arranged wheels covered with abrasive paper act on the coating of a rotating test specimen. Coating manufacturers and applicators use it to compare paint and varnish systems, check batches and support product data sheets. Since results depend on the coating, the substrate and the test setup, labs keep panel preparation and conditioning consistent, and confirm the edition and any requirements set by the product specification.
Rotary abraders such as our rotary abrasion tester are used for coating abrasion testing to ISO 7784-1. If you need help matching ISO 7784-1 requirements to your parts or setup, contact our team.
