Comprehensive Guide to ASTM D522 Impact Testing of Coatings on Substrates: A Laboratory Testing Service Provided by Eurolab
ASTM D522 Impact Testing of Coatings on Substrates is a widely accepted standard for evaluating the impact resistance of coatings on substrates. This standard is governed by the American Society for Testing and Materials (ASTM) and is used globally in various industries, including automotive, aerospace, construction, and manufacturing.
The ASTM D522 standard specifies the testing procedure for determining the impact resistance of coatings on substrates using a falling dart or a pendulum impact tester. The test involves dropping a weighted dart onto a coated substrate from a specified height, and the resulting damage is evaluated based on the extent of cracking, chipping, or other forms of deterioration.
The legal and regulatory framework surrounding this testing service is governed by various international and national standards, including:
