NOTE It is emphasized that only results on test pieces of identical dimensions should be compared. The total absorbed energy consists of: The resolution r of the indicator is obtained from the ratio of the pointer thickness and the minimum distance between the centres of two rn graduation marks.

This test may be carried out jointly with verifying the contact of the test piece over its whole length see 5.

NOTE This may be verified by means of a bar approximately 55 mm long and of rectangular cross-section: This standard is also applicable to pendulum impact machines of different capacities or different design.

If this mechanism also includes a braking system, means shall be provided to prevent the brake being applied accidentally. EU, Impact testing using V-notch, beam type test piece. NOTE 10045–2 possible method of verification is that described in 5.

In each case, the greater value is permitted. NOTE For machines in which the hammer opening permits a play of at least 13 mm between the end of the test piece placed ready for the test and the safety stops, requirements a and d do not apply.

This absorbed energy is a measure of the impact strength of the material. These losses can be determined by the direction method see 5. Until this European Standard is published reference can be made to the corresponding national or international standards, a list of which is given 100452- annex A. Method for the verification of impact testing machines. The plane of the supports is perpendicular to the plane of the anvils see Figure 1 3.

The notch shall be carefully prepared so that no grooves, parallel to the base of the notch, are visible to the naked eye. A fully enclosed, interlocked guard is provided to keep the operator safely away from moving parts.

It incorporates the corrigendum dated It shall meet the requirements of Table 2 in this standard except for the following parameters, for which stricter criteria shall be met: Motorized Pendulum Impact Testing System: The reference test pieces shall be used in accordance with the instructions given by the supplier. 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 the official versions.

Annex A describes, for information purposes, a direct method of verifying certain geometrical properties using a jig. We need your help! We use cookies to make our website easier to use and to better understand your needs.

The test report shall state that the test piece was not broken by x J. 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.

Report “BS EN “. NOTE This may be done, for example, by placing a container of water on the machine framework and checking that there are no ripples on the surface of the water.

It partially supersedes BS No part of the pendulum which passes between the anvils shall be thicker than 18 mm. Charpy impact test on metallic materials. The test piece may be marked on any face not in contact with the supports or anvils and at a point at least 5 mm from the notch to avoid the effects of cold working due to marking.
