T/GDTL 014-2021 Swing arm damping determination coating hardness intelligent method
Basic Information
Scope
Scope: This document describes a test method for automatically determining the hardness of coatings on single or multi-layer coatings on acceptable rigid surfaces, such as metal or glass plates, using a pendulum damping method. This method includes Konig's Method A and Persoz's Method B. This method is suitable for pendulum damping tests of relevant coatings (paints, varnishes) applied according to appropriate methods.
