Clevis Grips for Fracture Mechanics

Description

The Instron 2750 Series fracture mechanics grips are suited to static and dynamic testing of compact tension specimens in accordance with the following standards:

ASTM E 399
ASTM E 647
ASTM E 813
ASTM E1 290
BS 7448

Principle of Operation

The upper and lower grips are identical, and attach to the specimen by means of a clevis pin arrangement. The 10 kN and 50 kN grips require a set of adapters which provide for attachment to the load cell or actuator (via an appropriate attachment kit).Clevis pins are provided with spring clips or covers to prevent them from being shaken loose during testing.
