ISO 7765 ASTM D1709 Thin Film Falling Dart Impact Tester
This precision testing instrument evaluates the impact resistance performance of thin film materials using free-falling dart cascade methods, compliant with international standards including GB/T 9639.1-2008 Method A and ISO 7765-88 requirements.
Product Overview
The Thin Film Falling Dart Impact Tester is engineered to determine the impact resistance of plastic films and thin wafers through controlled free-fall impact testing.
Application Scope
This instrument is suitable for testing plastic films and wafers with thickness less than 1 mm, capable of measuring breakthrough quality for materials weighing 0.05 to 2 kg.
Testing Principle
Using either Method A or Method B, the instrument determines the falling mass quantity that causes 50% sample damage under specified test conditions.
