This compression jig adheres strictly to the ASTM D7012 Test Methods for Rock Core Specimens, specifically meeting the requirements for the ratios of spherical seat to compression plates to specimen diameters. The Rock core specimens used in this jig should have a diameter ranging from 47 mm to 63.5 mm. The jig comprises a robust twin-column frame, with an upper platen that is spherically seated and held in place by calibrated springs. The lower platen is centred on the base of the frame. The jig's design incorporates a highly rigid structure and employs high-performance steel for the spherical seat. These features make the device exceptionally well-suited for testing high-strength rock specimens that exhibit brittle properties and may undergo explosive failure.
