    1/ Filament lamps with cap BA 15d may be used for special purposes; they have the same dimensions.
    2/ Maximum lateral deviation of filament centre from two reciprocally perpendicular planes both containing reference axis and one containing axis of pins.
    3/ For 24V heavy-duty lamps having a different filament shape, additional specifications are under consideration.
4/ See paragraph 3.5.3.
