Unfortunately, the Martindale Abrasion method is not satisfactory or widely accepted as a method for approving shipments of fabric. The Martindale has issues in consistency and results can vary between operators. With this being a large downside of the Martindale system, the test method is still widely used outside of the United States and is in accordance to many ISO standards, ASTM D4966 as well as many EU and GB standards (ISO 20344, ISO 12947, ISO 17704, ASTM D4966-12e1 to name a few).
