All three standards provide details for properly measuring the energy absorbed by the notched specimen when impacted by a swinging ensxio. A typical Charpy test requires the notched metal specimen to rest on supports ensauo each end in a horizontal fashion while coming in contact with vertical anvils adjacent to the supports.

The specimen is then struck opposite the anvils at its centerline by a striker that is attached to a swinging pendulum hammer. The illustration image found above shows a common specimen arrangement for Charpy impact testing. In order to measure the toughness of a material using a Charpy impact test, it is necessary to prepare specimens from the material or product of interest.

In some cases, size limitations of the product needing tested charp not allow for standard size specimens to be prepared. In either scenario, it becomes necessary to test sub-size specimens.

These smaller specimens require supports that raise the specimen higher in order to keep it centered with the striker and anvils.

It is also necessary to make sure these smaller specimens produce impact energies that are above the lowest verifiable reading of the ensaioo impact testing system being used.

Both models accommodate optional support blocks for standard and reduced width specimens. Refer to the following part numbers.

Use of Fracta impact software with an integrated angular encoder on either the SI Series or MPX Series provides the best solution when really low impact energies are required. Available in capacities from to J the MPX is safe, quick, and easy to operate.
