About This Item
ASTM D662 is the standard test method for evaluating the degree of erosion of exterior paints, making it a practical reference for comparing how coatings hold up under exterior exposure. It helps users assess surface loss or wear in a consistent way, supporting product evaluation, quality control, and specification work. For organizations that need a reliable ASTM standard for coating performance, ASTM D662 provides a focused framework for judging erosion in exterior paint systems.
Overview of ASTM D662
ASTM D662 addresses a specific durability question: how much exterior paint has eroded after exposure. The standard is useful when a coating’s long-term condition needs to be measured in a repeatable, technical manner rather than by visual impression alone. As an ASTM standard, it supports more consistent evaluation of exterior paint performance and can be used to help compare materials, track aging effects, and document test results in a structured way.
Common use cases of ASTM D662
ASTM D662 is commonly used when exterior paints must be checked for erosion during development, qualification, or routine quality review. It may be applied in coating laboratories, technical service workflows, or maintenance-related evaluations where exterior durability matters. The standard is especially relevant for paint products and coated surfaces intended for outdoor exposure, where erosion can affect appearance, protection, and overall service life.
Benefits of using ASTM D662
Using ASTM D662 can improve consistency in test results and help teams compare exterior paint performance using a recognized method. It supports compliance efforts, product screening, and clearer communication between buyers, suppliers, and test laboratories. The standard also helps reduce uncertainty in coating evaluation by providing a defined way to assess erosion, which can be valuable for procurement, specification decisions, and quality control.
