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.

    6/ Glass bulb shall be optically distortion free within the angles g1 and g2. This requirement applies to the whole bulb circumference within the angles g1 and g2.
    7/ The obscuration shall extend at least to angle g3 and shall extend at least to the cylindrical part of the bulb on the whole bulb top circumference.
    8/ The internal design of the lamp shall be such that the stray light images and reflections are only located above the filament itself seen from the horizontal direction. (View A as indicated in figure 1, sheet H11/1).
    No metal parts other than filament turns shall be located in the shaded area as seen in figure 4.
    9/ The offset of the filament with respect to the reference axis is measured only in viewing directions A and B as shown in figure 1 on sheet H11/1. 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.
    10/ Eccentricity of bulb with respect to filament axis measured in two planes parallel to the reference plane where the projection of the outside of the end turns nearest to or furthest from the reference plane crosses the filament axis.
