STT-C

Function

Detect the tear resistance of films, sheets, and fabrics made of various materials.

Working principle

Raise the pendulum to a certain height to give it a certain potential energy; When the pendulum swings freely, it uses its stored energy to tear the sample; The computer control system calculates the energy consumed when tearing the specimen, thereby obtaining the force required to tear the specimen.

Compliant with national standards

ISO 6383-1、ISO 6383-2、 ISO 1974、GB/T16578.2、GB/T 455、ASTM D1922、ASTM D1424、ASTM D689、TAPPI T414。
