RockSchmidt The world's most advanced rebound hammer, with unmatched dispersion characteristics, durability and measuring range has now been fully adapted for rock testing. The following features of the hammer make it ideal for rock testing applications: Impact Angle Independence: The rebound value is independent of the impact direction. Optimized for Field Work: Tighter sealing against dirt and dust intrusion for longer life. Significantly lighter and more ergonomic than the classic Schmidt hammer. A large number of readings can be saved and downloaded later to a PC. Preset Statistics: Statistics...

Rock Testing Equotip 550 with Impact Devices D and S This makes it very suitable for testing on historical sites, very soft types of rock that cannot be tested with a rebound hammer and also on brittle rock cores that would be damaged by a rebound hammer. The impact device type S features the same impact energy and a much more durable ceramic impact body that is more suited to heavy users on harder rock. “Using Proceq’s NDT instruments significantly improves our understanding of the deterioration processes affecting heritage buildings.” Extensively used for rock hardness and for investigating...

Rock Testing Standards and Guidelines The following standards and guidelines apply to rock testing: • ASTM D 5873 – Standard Test Method for Determination of Rock Hardness by Rebound Hammer Method. (Applicable for UCS between 1 MPa and 100 MPa.) • ASTM D 2845 – Standard Test Method for Laboratory Determination of Pulse Velocities and Ultrasonic Elastic Constants of Rock. • ISRM – Aydin A., ISRM Suggested method for determination of the Schmidt hammer rebound hardness: Revised version.
