1/ To be checked by means of a box system, sheet H21W/2.
    2/ Maximum lateral deviation of filament centre from two mutually perpendicular planes both containing the reference axis and one containing the axis X-X.
    3/ The lateral deviation with respect to the plane perpendicular to axis XX, is measured in the position described in clause 1 of the test procedures on sheet H21W/2.
    4/ In the area between the outer legs of the anglesamma 1 and gamma2, the bulb shall have no optically distorting areas and the curvature of the bulb shall have a radius not less than 50%
