Additional explanations to Sheets HS1/4 and HS1/5
The dimensions below are measured in three directions:
     1. for dimension a, b1, c, d, e, f, 1r and 1c;
     2. for dimensions g, h, p and q;
     3. for dimension b2.
Dimensions p and q are measured in a plane parallel to 33mm away from the reference plane. Dimensions b1, b2, are measured in planes parallel to and 29.5 and 33mm away from the reference plane. Dimensions a and g are measured in planes parallel to and 25 and 26mm away from the reference plane. Dimensions c and h measured in planes parallel to and 29.5 and 31mm away from the reference plane.

    1/ Where a yellow outer bulb is used, "m" and "n" denote the maximum dimensions of this bulb; where there is no outer bulb, "m" denotes the maximum length of the lamp.

    2/ It must be possible to insert the filament lamp into a cylinder of diameter "s" concentric with the reference axis and limited at one end by a plane parallel to and 20mm distant from the reference plane and at the other end by a hemisphere of radius s/2.

    3/ The obscuration must extend at least as far as the cylindrical part of the bulb. It must also overlap the internal shield when
