and its position relative to the reference axis and plane by measuring its bending and diffusion in the cross section at a distance 27.1mm from the reference plane.

The form of the arc is for illustration purposes only.

When measuring the relative luminance distribution in the central cross section as indicated in the drawing above, the maximum value shall be located within a distance r from the reference axis. The points of 20% of the maximum value shall be within s.

    1/ The reference plane is defined by the positions on the surface of the holder on which the three supporting bosses of the cap ring will rest.
2/ See sheet D1R/D2R/2.
    3/ With respect to the reference axis, when measured at a distance of 27.1mm from the reference plane the eccentricity of the outer bulb shall be less than +/- 0.5mm in direction B and less than + 1mm - 0.5mm in direction A.
