EN-ISO 1520

Introducing EN-ISO 1520 – Industrial Physics

EN-ISO 1520 is an international testing standard that was developed to guide the deformation resistance testing of paints and varnishes using the cupping test approach. 

This EN-ISO testing method specifies an empirical test procedure for assessing the resistance of coatings to cracking and/or detachment from a metal substrate when subjected to gradual deformation by indentation under standard conditions. If you’re working with multi-coat systems, each coat may be tested separately, or the complete system may be tested. 

The EN-ISO I520 paint testing process

You can perform a compliant paint test to EN-ISO 1520 standards by following either of the following two approaches.   

1. a ‘pass/fail’ test, by testing to a specified depth of indentation to assess compliance with a particular requirement 
2. Gradually increase the depth of indentation to determine the minimum depth at which the coating cracks and/or becomes detached from the substrate.
