Inorganic Surface Coatings – Methods for Measuring Ductility – Overview. ISO 8401:2017 provides an overview of various methods for measuring the ductility of inorganic surface coatings, which is a measure of the coating’s ability to deform without cracking. The standard outlines the principles of several testing methods used to determine ductility, such as bend testing, tensile testing, and impact testing. Each method offers specific advantages depending on the type of coating and substrate being tested. Ductility measurement is crucial for ensuring that coatings applied to flexible or stressed surfaces retain their protective properties without cracking or detaching. The standard is intended for manufacturers and laboratories verifying the mechanical properties of surface coatings.
