    1/ Maximum lateral deviation of filament centre from two reciprocally perpendicular planes both containing the reference axis and one containing axis X-X.
    2/ In the area between the outer legs of the angles gamma1 and gamma2 the bulb shall have no optically distorting areas and the curvature of the bulb shall have a radius not less than 50% of the actual bulb diameter. 3/Over the entire length of the cap there shall be no projection or soldering exceeding the permissible maximum diameter of the cap.

Sheet HB3/1

 The drawings are only to illustrate the essential dimensions of the filament lamp

1/ The reference plane is the plane defined by the meeting points of the cap-holder fit.
    2/ The reference axis is perpendicular to the reference plane and concentric with the reference diameter of the cap.
    3/ Glass bulb and supports shall not exceed the envelope and shall not interfere with insertion past the lamp key. The envelope is concentric to the reference axis.
4/ The keyway is mandatory.
    5/ The filament lamp shall be rotated in the measuring holder until the reference lug contacts plane C of the holder.

Sheet HB3/2

6/ The bulb shall be colourless or yellow.
    7/ Glass bulb periphery shall be optically distortion-free axially within the angles gamma1 and gamma2. This requirement applies to the whole bulb circumference within the angles gamma1 and gamma2.
