    7/ The eccentricity is measured only in viewing directions A and B as shown in the figure on sheet HIR2/1. 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.
8/ The viewing direction is direction B as shown in the figure on sheet HIR2/1.
9/ To be checked by means of a "box-system". Sheet HIR2/3.
    10/ The ends of the filament are defined as the points where, when the viewing direction as defined in note8/ above, the projection of the outside of the end turns crosses the filament axis.
11/ Dimensions shall be checked with O-ring removed.
CATEGORY HIR2

Sheet HIR2/3
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 lamp complies with the requirements.
