    5/ The end turns of the filaments are defined as being the first luminous turn and the last luminous turn that are at substantially the correct helix angle. For coiled-coil filaments, the turns are defined by the envelope of the primary coil.

    6/ For the passing-beam filament the points to be measured are the intersections, seen in direction (1), of the lateral edge of the shield with the outside of the end turns defined under foot-note 5.

    7/ "e" denotes the distance from the reference plane to the beginning of the passing-beam filament as defined above.

    8/ For the driving-beam filament the points to be measured are the intersections, seen in direction (1), of a plane, parallel to plane HH and situated at a distance of 0.8mm below it, with the end turns defined under foot-note 5.

    9/ The reference axis is the line perpendicular to the reference plane and passing through the centre of the circle of diameter "M" (see sheet H4/1)

    10/ Plane VV is the plane perpendicular to the reference plane and passing through the reference axis and through the intersection of the circle of diameter "M" with the axis of the reference pin.

    11/ Plane HH is the plane perpendicular to both the reference plane and plane VV and passing through
