    IS 9873-4 /ISO 8124-4 Alu Alloy Impact Head For Swing Elements Without Accelerometer

    ISO 8124-4 Impact Head from swing elements (without Accelerometer)


    Product introduction

    Test mass, consisting of an aluminium sphere or semi-sphere of radius 80 mm ± 3 mm, and a total mass
    (including accelerometer) of 4,6 kg ± 0,05 kg. The impacting part between the surface struck and the
    accelerometer shall be homogeneous and free from voids. Cables connected to the accelerometer shall
    be placed in such a way that the effect on the mass of the test mass is minimized


    Test Standard

    ISO8124-4 6.4.1


    Procedure

    Assemble and install the swing element to be tested in accordance with the manufacturer's instructions.
    Suspend the swing with the means of suspension that has been supplied with the swing and at the maximum
    height that these permit. If ropes or cables are the means of suspension, they may need to be stretched in
    order to allow smooth travel when the swing is released during the test. If needed, apply a load of, for example,
    5 kg to the end of each rope or cable and leave it for 6 h or until the ropes or cables have been straightened.
    Adjust all parts of the set-up so that the suspending chains for the test mass are parallel to the means of
    suspension for the swing element.
    Suspend and adjust the test mass so that the contact point of the swing element and the centre of the test
    mass are in the same horizontal plane as the centre of gravity of the test mass. Ensure that the chains for test
    mass are not twisted and that the test mass hangs in a vertical line.
    Affix an index mark to the side of swing elements that are supported by chains, ropes, cables or other
    non-rigid suspending elements. The index mark may be on any part of the suspended member that is
    immediately below the pivot point in the free-hanging rest position.
    Swing elements that are supported by chains, ropes, cables or other non-rigid suspending elements shall be
    raised along their arc of travel until the side-view projection of a straight line through the pivot point and index
    mark forms an angle of 60° ± 1° with the vertical. Once the suspended member is raised to the test position,
    some curvature will be produced in the suspending elements. Adjust the suspended member position to
    determine that curvature which provides a stable trajectory.
