Class J is widely used for lzod and Charpy impact test on softer metals, plastics and rubber specimens. Equipped with tensile impact pendulum and fixtures, it can carry on tests on plastic film and sheet. The newly enhanced design offers the most cost-effective configuration to address Charpy test from 1J to 50J, and lzod test from 1J to 22J.

A test method for determining energy required to fracture a specimen under shock tensile loading. Typically executed on a pendulum testing machine, the tensile impact strength test was originally developed to overcome the deficiencies of flexural (both Izod and Charpy) impact test. All the test variables that have a high effect on the results ...

Nov 18, 2021· An impact pendulum that follows strictly Bond's standard for crushability measurement [5, 32, 33] has been used, which allows calculating the crushing, or impact, work index. The test consists of dropping two pendulum-mounted hammers simultaneously, each weighing 13.6 kg, against individual particles of size ranging from …

· The Bond crushing work index test (sometimes called the "impact work index" test) is noisy, and the difference you observed is perfectly reasonable. The paper by Angove & Dunne (1997) reports a standard deviation in crushing work index tests across laboratories as 4.5. contact us

The Bond low-energy impact test apparatus consists of two pendulum hammers mounted on two bicycle wheels, so as to strike equal blows simultaneously on opposite sides of each rock specimen. The height of the pendulum is raised until the energy is sufficient to break the specimen (Bond, 1947), and then the crusher work index (CWI) or impact work ...
