NOTE It is emphasized that only results on test pieces of identical dimensions should be compared. The test piece may be marked on any face not in contact with the supports 10405-2 anvils and at a point at least 5 mm from the notch 1045-2 avoid the effects of cold working due to marking. This European Standard takes into account the total energy absorbed by the fracture of the test piece.

For a machine of A joules, verify the indicator graduations corresponding to or percent of the initial potential energy AN. 100455-2 width of the scale graduation marks shall be uniform and the width ej the pointer shall be approximately equal to the width of one graduation mark.

Next Checking to see if you are a returning visitor…. This shall be verified by direct measurement, unless a reference plane can be machined on the machine and then the above requirement shall be met. Verification of pendulum impact testing machines. E5 be the values of the energy absorbed when breaking 5 test pieces, classified in ascending order.

BS EN 10045-2:1993

For tests at temperatures other than ambient, 110045-2 test piece shall be immersed in the cooling or heating medium for sufficient time to ensure that the required temperature is reached throughout the test piece for example, at least 10 min in a liquid medium or at least 30 min in a gaseous medium. If this mechanism also includes a braking system, means shall be provided to prevent the brake being applied accidentally.

The energy losses are due to: These losses can be determined by the direction method see 5. If standard test pieces cannot be obtained from the material, a reduced section test piece, with a width of 7,5 mm or 5 mm see Table 2 shall be used, the notch being cut in one of the narrow faces.

The faster, easier way to work with standards. Also wrap the striking edge in carbon paper, the carbon side facing outwards.

Comparison of results, however, is only of significance when made between test pieces of the same form and dimensions. 1045-2 this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more! Email addresses can only contain letters, numbers and the following special characters: Annex B describes, 1005-2 information purposes, a guide to the preparation of reference test pieces and their characteristics.

The notch shall be carefully prepared so that no grooves, parallel to the base of the notch, are visible to the naked eye. It describes 2 methods: Annex A describes, for information purposes, a direct method of verifying certain geometrical properties using a jig.

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. NOTE The radial play may be measured, for example, by placing a dial gauge on the framework in order to indicate the movement at the end of the shaft at the point closest to the bearings. This will be indicated in the amendment table on the inside front cover. The friction losses of the pointer are equal to: Compliance with a British Standard does not of itself confer immunity from legal obligations.

The test pieces shall be machined all over, except in the case of precision cast foundry test pieces in which the two faces parallel to the plane of symmetry of the notch can be unmachined.
