I. Instrument overview

This machine is primarily designed to test the impact resistance of unplasticized polyvinyl chloride (PVC-U) profiles. It employs a falling ball impact test with a specified height and mass, and evaluates the test results using a pass/fail method. It is suitable for PVC-based profiles used under specific temperature or testing conditions.

II. Applicable standard

This machine adopts manual lifting for ball drop, with lifting height scale marks marked on the column. It features a structure that prevents secondary impact, is easy to operate, and can quickly clamp the specimen.
