AS 1544.1:2003 pdf download.Methods for impact tests on metals Part 1: lzod.

The test piece is clamped vertically in supports with the notch iii the same plane as the tipper face of the support. The blow is

struck on the face containing the notch and at a fixed distance above it. Using a single blow from a pendulum to break a clamped

notched test piece using the energy absorbed by the material to determine the measurement.

5 TESTING MAChINE

5.1 General

The testing machine shall be of the pendulum type. and shall be so constructed that the loss of energy (such as from translation,

rotation or vibration) in the machine framework and pendulum during a test, is negligible.

5.2 Installation, calibration and maintenance

The machine shall he installed and calibrated in accordance with Paragraphs Al and A2 of Appendix A. It shall be recalibrated

periodically, and when otherwise necessary, in accordance with Paragraph A2 of Appendix A.

The machine should be maintained in satisfactory working order and condition in the intervals between successive recalibrations. in accordance with Paragraph A3 of Appendix A.

5.3 Test piece supports

The test piece supports shall be of hardened steel and shall consist of a support block and a clamp block, see Figures 1(a) and 1(b).

The support block shall be provided with a vertical groove for locating the test piece in the plane of the swing of the pendulum.

The location groove shall conform to the requirements of Table I and the following requirements.
