3                     Applicable to filaments which can be inscribed in a rectangle of b<3h, whereby however k < 2h.

 The side lines of the circumscribed rectangles in Nos. 2 and 3 are parallel and perpendicular, respectively, to the reference axis.

 The luminous centre is the point of intersection of the dash-dot lines.

CHECKING THE COLOUR AND TRANSMISSION OF SELECTIVE-YELLOW BULBS AND OUTER BULBS AND AMBER BULBS

  1.                                                   General specifications

1.1. The manufacturer shall send to the test laboratory five finished filament lamps with coloured bulb or coloured outer bulb. Filament lamps with coloured outer bulb shall be handled as filament lamps with coloured bulb.

            1.2. All the tests shall be made at an ambient temperature of 23 degrees C +/- 5 degrees C.

 1.3. The tests shall be made at test voltage.

l.4. Before starting each test the stabilisation of the temperature of the filament lamp shall be obtained by operating at test voltage for 10 minutes.

 2.                                                     Colour

2.1. The colour should be so homogeneous that at visual inspection no essential differences are perceptible.
2.2. Measuring the colour the reference axis of the filament lamp shall be vertical with the cap down. The measuring direction shall be perpendicular to the reference axis and to the axis of the filament too. In case of doubt with regard to homogeneous colour the sample shall be measured in several directions and all shall comply.
2.3. The test shall be made with a measuring system which shows the CIE chromaticity co­ordinates of the received light with an accuracy of +/- 0.002.
2.4. In the case of measuring the colour of filament lamps with selective-yellow bulb the measurement shall be made by integrating within a cone having an apex angle of 60 degrees perpendicular to the reference axis of the filament lamp with the origin in the centre of the main beam filament.
2.5. In the case of measuring the colour of filament lamps with amber bulb the measurement shall be made by integrating within a cone having an apex angle of 4 degrees perpendicular to the reference axis of the filament lamp with the origin in the centre of the filament.

 3.                                                     Transmission

3.1. The transmission shall be such that the emitted luminous flux of the filament lamp lies within the tolerance values specified for the relevant filament lamp in this Regulation.

MINIMUM REQUIREMENTS FOR QUALITY CONTROL PROCEDURES BY THE MANUFACTURER

             1. GENERAL

            The conformity requirements shall be considered satisfied from a photometric, geometrical, visual and electrical standpoint if the specified tolerances for production filament lamps in the relevant data sheet of annex 1 and the relevant data sheet for the caps are met.

            2.                                                       MINIMUM REQUIREMENTS FOR VERIFICATION OF
