Elmendorf pendulum type tearing tester gf/mN units touch screen operation pneumatic release microprinter

Elmendorf pendulum type tearing tester measures the average force to propagate tearing through a specified length of plastic film or nonrigid sheeting after the tear has been started. It helps to rank relative tearing resistance of various plastic films and thin sheeting of comparable thickness.

Elmendorf pendulum type tearing tester  Principle:

Acting by gravity, the pendulum swings through an arc, tearing the specimen from a precut slit. This loss in energy indicates the force required to tear the specimen.

Elmendorf pendulum type tearing tester Standards:

ASTM D1922: Standard Test Method for Propagation Tear Resistance of Plastic Film and Thin Sheeting by Pendulum Method

ASTM D1424: Standard Test Method for Tearing Strength of Fabrics by Falling-Pendulum (Elmendorf-Type) Apparatus
