6/ To be checked by means of a "box-system"; sheet H3/4.
    7/ For standard filament lamps the points to be measured are those where the projection of the outside of the end turns crosses the filament axis.
    8/ The positions of the first and the last turn of the filament are defined by the intersections of the outside of the first and of the last light emitting turn, respectively, with the plane parallel to and 18 mm distant from the reference plane (additional instructions for coiled-coil filament are under consideration.

Screen projection requirements
This test is used to determine, by checking whether the filament is correctly positioned relative to the reference axis and the reference plane, whether a filament lamp complies with the requirements.

    1/ The reference plane is the plane formed by the underside of the beveled lead-in flange of the cap.
    2/ The reference axis is perpendicular to the reference plane and passing through the centre of the 19mm cap diameter.
    3/ Glass bulb and supports shall not exceed the envelope as indicated in figure 2. The envelope is concentric to the reference axis.
4/ The bulb shall be colourless or yellow.
5/ Notes concerning the filament diameter.
    - No actual diameter restrictions apply but the objective for future developments is to have - d max. = 1.4 mm
    For the same manufacturer, the design diameter of standard (etalon) filament lamp and filament lamp of normal production shall be the same.
