    1/ The reference axis is the perpendicular to the reference plane and passing through the point defined by the dimensions marked with 1/.
    2/ Both current lead-in electrodes shall be positioned in the bulb, the longer electrode above the filament (the lamp being viewed as shown in the figure). The internal design of the lamp should then be such that stray light images and reflections are reduced to the minimum, e.g. by fitting cooling jackets over the non-coiled parts of the filament.
    3/ The cylindrical portion of the bulb over length 'f' shall be such as not to deform the projected image of the filament to such an extent as appreciably to affect the optical results.
    4/ The eccentricity is measured only in the horizontal and vertical directions of the filament lamp as shown in the figure. The points to be measured are those where the projection of the outside of the end turns nearest to or furthest from the reference plane crosses the filament axis.
    5/ The viewing direction is the perpendicular to the reference axis contained in the plane defined by the reference axis and the centre of the second pin of the cap.
    6/ Offset of filament in relation to bulb axis measured at 27.5mm from the reference plane.
7/ d: diameter of filament.
8/ To be checked by means of a 'box-systemi, sheet H1/4.
    9/ The ends of the filament are defined as the points where, when the viewing direction is as defined in footnote 5 above, the projection of the outside of the end turns nearest to or furthest from the reference plane crosses the reference axis (special instructions for coiled-coil filaments are under consideration).

Screen projection requirements
This test is used to determine, by checking whether the filament is correctly positioned relatively to the reference axis and the
