ASTM D1825-03 PDF Download

ASTM D1825-03 is a standard practice that outlines the procedure for etching and cleaning copper-clad electrical insulating materials and thermosetting laminates for electrical testing. The purpose of this practice is to provide guidelines for preparing these materials for testing by removing any contaminants or unwanted substances that may interfere with accurate results.

The standard describes a specific procedure to be followed for etching and cleaning, providing step-by-step instructions. It emphasizes the importance of rigorous cleaning and removal of any residues, including oxidized copper, oils, and grease, to ensure a clean and uniform surface. This is crucial for obtaining reliable and consistent test results when evaluating the electrical properties of these materials.
