Introduction: Film drop dart impact testing machine for testing the impact resistance of thin film materials and design, the use of free dart method cascade method. Tester to implement GB / T9639 (plastic film and sheet impact resistance test method free fall dart method), ASTM D1709, JIS K7124 and ISO7765-1: 1988 standard requirements. Related Standards for Plastic Films or Sheets of Thickness Less than 1mm Determining the impact impact quality and energy of plastic film and sheet specimens for damage under free-falling dart impact at a given height can be used for professional equipment for food packaging QS certification. The instrument is suitable for plastic film and the thickness of less than 1mm sheet, breaking the quality of 0.05 ~ 2kg of material. Principle: Under the given conditions, the A method is used to determine the mass of the falling body with the number of breakage of 50%. Technical Parameters: Maximum impact energy: 30J Measurement methods: A method, B method (optional) Test range: A method: 50 ~ 2000gB method: 300 ~ 2000g Dart head half diameter: A method: 38MM, B method: 50MM Test height: 0.3-1.8M manually adjustable Test conditions: 23 ℃ 50% RH (standard) Sample folder: Pneumatic Fixture diameter: 125MM
