Inspection, calibration and verification of the machines in Parts 1, 2 and 3. Accuracy of gauges used in checking components, in an appendix.

1.1 This Part of this British Standard gives methods for the inspection, calibration and verification of Izod pendulum impact testing machines, and includes instructions for certificates of calibration and verification. The methods cover the following elements of the machine, which are illustrated in Figure 1:

machine framework (i.e. the structure supporting the pendulum, excluding only the foundation);
pendulum and striker;
test piece supports;
indicating equipment (e.g. scale and friction pointer).

1.2 In applying the methods all the absorbed energy indicated by the machine is attributed to the fracturing of the test piece.

NOTE It is known that energy is absorbed other than by fracturing the test piece. It is assumed that this energy is absorbed by items such as the test piece supports, the machine foundation and framework, the pendulum and striker, translation of the broken part of the test piece and drag of a partially broken test piece. This energy is not determined as suitable methods and apparatus have not yet been developed for measuring either its total or constituent parts.
