When the readings fluctuate by more than one increment, the resolution is taken to be equal to half the range of the fluctuation. Report “BS EN “. If this mechanism also includes a braking system, means shall be provided to prevent the brake being applied accidentally.

It partially supersedes BS Until this European Standard is published reference can be made to the corresponding national or international standards, a list 10405-2 which is given in annex A. NOTE One possible method of verification is that described in 5. General, 110045-2 and deviations.

The mark by the carbon paper on the paper the test piece is wrapped in makes it possible to measure its orientation in relation to the horizontal axis of the test piece. The apparatus used for the direct method shall have enn certified traceability relative to the SI wn of units. The plane of the supports is perpendicular to the plane of the anvils see Figure 1 3. Ministry of Defence Society of British Aerospace Companies Limited Welding Institute The following bodies were also represented in the drafting of the standard, through subcommittees and panels: NOTE One possible method of verification is as follows.

NOTE For the evaluation the following energies are not taken in account: You may find similar items within these categories by selecting from the choices below:. It describes 2 methods: This standard is also applicable to pendulum impact machines of different capacities or different design. Annex A describes, for information purposes, a direct method of verifying certain geometrical properties using a jig.

The machine includes a motorized return of the hammer to the release point to eliminate any operator lifting of the hammer preventing injury. NOTE This may be verified by means of a bar approximately 55 mm long and of rectangular cross-section: The following member bodies were represented at this meeting: 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.

These losses are evaluated as follows. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. EUCharpy impact test for steel. This shall be certified by the manufacturer of the machine.

This absorbed energy is a measure of the impact strength of the material. The test report shall state that the test piece was not broken by x J. Available in capacities from to J the MPX is safe, quick, and easy to operate. 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.

Verification of pendulum impact testing machines. It incorporates the corrigendum dated For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. Users of British Standards are responsible for their correct application. This European Standard takes into account the total energy absorbed by the fracture of the test piece.

The direct method shall be used, firstly, when the machine is being installed or repaired and, secondly, if the indirect method gives an incorrect result see 8. Consequently, the documentation prepared when the machine is installed shall prove that the mass of the foundation is at least 40 times that of the pendulum which shall also be given in the documentation.

Email addresses must contain the symbol. A fully enclosed, interlocked guard is provided to keep the operator safely away from moving parts. The distance between the striking edge and the bar is measured.

Verification de la machine d’essai mouton-pendule. It shall meet the requirements of Table 2 in this standard except for the following parameters, for which stricter criteria shall be met: The friction losses of the pointer are equal to: Please 10054-2 that you agree with our privacy and cookies policy to submit this form.

If more than 2 energy levels are verified, the additional levels shall be uniformly distributed in the range of application and as a function of the 1004-2 reference test pieces.
