       EXAMPLE OF ARRANGEMENT OF THE APPROVAL MARK

       (see paragraph 2.4.3.)

The above approval mark affixed to a gas-discharge light source indicates that the light source has been approved in the United Kingdom (E11) under approval code 0Al.  The first character of the approval code indicates that the approval was granted in accordance with the requirements of Regulation No. 99 in its original form.

Annex 4

METHOD OF MEASUREMENT OF ELECTRICAL AND PHOTOMETRIC CHARACTERISTICS

       1. General

       For starting, run-up and hot-restrike tests and for the measurement of electrical and photometric characteristics, the gas-discharge light source shall be operated in free air with an ambient temperature of 25 +/- 5 degrees C.

       2. Ballast

       All tests and measurements shall be carried out with the ballast submitted in accordance with paragraph 2.2.2.4. of this Regulation.  The power supply used for the starting and run-up tests shall be sufficient to secure the quick rise of the high current pulse.

       3. Burning position

       The burning position shall be horizontal within +/- 10 degrees with the lead wire down. Ageing and testing positions shall be identical. If the lamp is accidentally operated in the wrong direction, it shall be re-aged before measurements begin. During ageing and measurements no electrically conducting objects shall be allowed within a cylinder having a diameter of 32mm and a length of 60mm concentric with the reference axis and symmetrical to the arc. Moreover stray magnetic fields shall be avoided.

       4. Ageing
