The Scleroscope test is a very old test that involves dropping a diamond tipped hammer, which falls inside a glass tube under the force of its own weight from a fixed height, onto the test specimen. The height of the rebound travel of the hammer is measured on a graduated scale. The Scleroscope Hardness Test. The Scleroscope test consists of dropping a diamond tipped hammer (size of 40 grains/ 2.59 gm/ 0.0914 oz) which falls inside a glass tube under the force of its own . The Scleroscope Hardness Test, developed by Albert F. Shore in the early 20th century, is a dynamic hardness testing method that measures the rebound hardness of materials. Unlike static methods, which involve the penetration of an indenter into the material, the Scleroscope test uses a diamond-tipped hammer that drops from a fixed height onto .
Standard Test Method for Scleroscope Hardness Testing of Carbon and Graphite Materials 1.1 This test method covers the apparatus and procedure for determining the hardness of carbon and graphite materials using the Model C-2 scleroscope² with the hammer calibrated for use on carbon and. Albert F. Shore, who founded the Shore Instrument Manufacturing Co. in New York, and whose name is now synonymous with durometer testing, engineered the Scleroscope as an alternative hardness test. The Scleroscope used a diamond tipped “hammer,” held within a glass-fronted tube that fell, from a height of 10 inches, onto a test specimen.

The test procedures for the Shore scleroscope were as follows: (i) The test surfaces were prepared using silicon car- bide grit size 600; (ii) The spacing between indentations was 2 mm on a grid system; (iii) Test specimen thickness was steadily reduced from over 50 mm down to 1.4 mm; (iv) The Shore hardness was taken as the average of 15 . Albert F. Shore, who founded the Shore Instrument Manufacturing Company in New York, and whose name is now synonymous with durometer testing, engineered the Scleroscope as an alternative hardness test. The Scleroscope used a diamond tipped “hammer”, held within a glass-fronted tube that fell, from a height of 10 inches, onto a test . Dynamic Hardness Test The dynamic hardness of a material is the measure of rebound or velocity of the rebound produced by a rapidly falling mass that includes an indenter. The most commonly used test method employs the Scleroscope tester, invented in 1906 by A.F. Shore and still used today.A type of hardness test. The scleroscope hardness test measures the amount of rebound that a diamond tipped hammer has when it is dropped on a material from a fixed height. Synonyms and Related Terms.

Scleroscope Test. Rebound Hardness Test A scleroscope is a device used to measure the rebound or dynamic hardness of materials. The setup consists of a . Use of the D-762 shore hardness scleroscope for testing small rock volumes. . Shore Scleroscope hardness, SSH; Vickers hardness, HV; Brinell hardness, HB; and Indentation hardness index, IHI). For this purpose, the most appropriate and meaningful relations between hardness tests and UCS-E were determined by simple regression (SR) techniques. .
materials testing: Hardness testing. . The Shore scleroscope measures hardness in terms of the elasticity of the material. A diamond-tipped hammer in a graduated glass tube is allowed to fall from a known height on the specimen to be tested, . In general, dynamic rebound hardness methods (Schmidt hammer, Shore scleroscope, Leeb hardness, etc.) are widely used, because they are economical and practical compared to static and indentation based hardness test methods (Brinell, Vickers, Rockwell, Knoop, Cherchar; ASTM 2013). Rebound hardness is a measure of the rebound of an object . Haigh B. P.: ‘Prism hardness: a new method of testing hardness in materials yielding a scale that is equally applicable to the hardest and softest metals and expresses the values in units of stress’, Proc.

Many studies had been carried out to correlate the engineering properties of rock with its physical index properties. Griffith (1937) correlated the unconfined compressive strength of different rock types (sedimentary, igneous, and metamorphic rocks) with shore scleroscope hardness according to the equation: UCS = 300 × (1 ± 0.1) S h, where UCS is .
Extreme under-weight specimens, inert and over-weight masses, the effect of hardness on mass and the effect of thickness of the test-specimen receive consideration, together with points concerning testing near test-specimen edges, the effect of curved surfaces and how test-specimens are held.
