Technical Specification
A sturdy bench top mounted unit for the study of notched bar (Charpy) impact strength tests. A heavy base plate with protective guard surrounds all the components, the guard has a lockable door for ease of access when setting the test but also security whist not in use. The base plate has an anvil and pillar which have replicable impact profiles for supporting the notched specimens prior to testing. A heavy hammer swings on a pre-defined radius, set by the hammer arm. The initial energy of the hammer can be varied by changing the starting weight and/or the start height of the hammers’ swing. Height variation can be varied between 3 set positions. As the hammer swings through its radius, it impacts on the specimen and the distance it travels passed the specimen is measured on an integral scale shown in degrees. A brake system stops the hammer swing after impact of specimen. A pointer travels with the hammer upon specimen breakage, thus indicating the change in angle from start position to highest point after fracture. The marker remains in position following specimen fracture to enable the value to be recorded. This can then be used to calculate the amount of energy absorbed by the specimen. The release of the hammer is controlled with a plunger. A push block is situated on the protractor face, this facilitates a two-handed operation and keeps the user away from the swinging arm for full safety. A number of test specimens are provided, with further specimens available separately. The specimens are manufactured to specific notched specifications (British Standards EN 10045-1 (1990)) and come in aluminum and brass.
