    1/ These dimensions should be checked by means of a "box system" */ based on the dimensions and tolerances shown above. "x" and "y" refer to the main (high wattage) filament, not to the lamp axis. Means of increasing the positioning accuracy of the filament and of the cap-holder assembly are under consideration.
*/ The "box-system" is the same as for filament lamp P21/5W.
    2/ Maximum lateral deviation of main filament centre from two reciprocally perpendicular planes both containing reference axis and one containing axis of pins.
