8/ Dimensions shall be checked with O-ring removed.
9/ The viewing direction is direction A as shown in the figure on sheet H12/1.
    10/ The ends of the filament are defined as the points where, when the viewing direction as defined in note 9/ above, the projection of the outside of the end turns crosses the filament axis.
11/ To be checked by means of a " box-system".  Sheet H12/3.
    12/ Dimensions h1 and h2 are measured in viewing direction A, dimension h3 in direction C and dimension h4 in direction B as shown in the figure on sheet H12/ 1. The points to be measured are those where the projection of the outside of the end turns crosses the filament axis.
13/ Dimension k is measured only in viewing direction A.

Sheet H12/3
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 filament lamp complies with the requirements.
