The plane of the anvils is perpendicular to the plane of the supports see Figure 1. To do this, lift the pendulum driving the indicator in the rise direction until the indicator is on the graduation to be verified. The width of the scale graduation marks shall be uniform and the width of the pointer shall be approximately equal to the width of one graduation mark. You may find similar items within these categories by selecting from the choices below:.

Then, without re-adjusting the pointer, release the pendulum to allow 10 half-swings. It represents the first part of the general standard: We are a non-profit group that run this website to share documents. Charpy impact test on metallic materials. EU, Impact testing using Een, beam type test piece.

The following member bodies were represented at this meeting: For a machine of A joules, verify the indicator graduations corresponding to or percent of the initial potential energy AN. For the U-shaped hammers, means shall be provided to eh the broken parts of the test piece from rebounding onto the hammer. The plane of the supports is perpendicular to the plane of the anvils see Figure 1 3.

A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as e official versions. The moment M of the pendulum is: Metallic materials — Impact test. Subscribe to Instron News! NOTE For machines manufactured after the publication of this standard, it is recommended that the mass of sn pedestal of the machine should be at least 12 times the mass of the pendulum.

Instead of determining the weight F1 of the pendulum and the distance from its centre of gravity to the axis, it is easier to determine a force F such that — acting at a known distance l2 from the axis — it has the same moment relative to this axis as the weight of the pendulum. Therefore, determine the time t of the pendulum and calculate l1 using the formula: The anvils shall lie in one and the same plane; the distance between the two planes shall never exceed 0,1 mm.

Method of test; — Part 2: NOTE It is emphasized that only results on test pieces of identical dimensions should be compared. How can we help you? The pointer shall permit a reading free from parallax. Any defects determined shall be indicated in the verification report. No part of the pendulum which passes between the anvils shall be thicker than 18 mm.
