Spencer Impact Tester
Available from Thwing-Albert Instrument Co.
The Spencer Impact Attachment was developed for use with Thwing-Albert's Elmendorf Tear Tester. It provides a convenient method for determining the impact resistance of plastic films and packaging materials under conditions that closely approximate the strain rates that the material is subject to in end-use applications. Extremely consistent, the Spencer Impact Attachment provides one of the most repeatable methods of testing impact resistance of plastic film. The air-operated clamping assembly automates the clamping mechanism to ensure an even higher level of accuracy.
