2.1. Definitions

2.1.1. The term ‘category’ is used in this Regulation to describe different basic design of standardised gas-discharge light sources. Each category has a specific designation, as for example: ‘D2S’.

2.1.2. ‘Gas-discharge light sources of different types’ (1) are gas-discharge light sources within the same category which differ in such essential respects as:

2.1.2.1. Trade name or mark; that means: (a) gas-discharge light sources bearing the same trade name or mark but produced by different manufacturers are considered as being of different types; (b) gas-discharge light sources produced by the same manufacturer differing only by the trade name or mark may be considered to be of the same type;

2.1.2.2. Bulb and/or cap design, in so far as these differences affect the optical results.

2.2. Application for approval

2.2.1. Application for approval shall be submitted by the owner of the trade name or mark, or by his duly accredited representative.

2.2.2. Every application for approval shall be accompanied (see also paragraph 2.4.2) by:

2.2.2.1. drawings in triplicate, sufficiently detailed to permit identification of the type;

2.2.2.2. a technical description including, if the ballast is not integrated with the light source, ballast identification;

2.2.2.3. three samples of each colour which has been applied for;

2.2.2.4. one sample of the ballast in case the ballast is not integrated with the light source.

2.2.3. In the case of a type of gas-discharge light source differing only by the trade name or mark from a type that has already been approved it shall be sufficient to submit:

2.2.3.1. a declaration by the manufacturer that the type submitted is identical (except in the trade name or mark) to and has been produced by the same manufacturer as, the type already approved, the latter being identified by its approval code;

2.2.3.2. two samples bearing the new trade name or mark.

2.2.4. The Competent Authority shall verify the existence of satisfactory arrangements for ensuring effective control of the conformity of production before type-approval is granted.

2.3. Inscriptions

2.3.1. Gas-discharge light sources submitted for approval shall bear on the cap or bulb:

2.3.1.1. the trade name or mark of the applicant;

2.3.1.2. the international designation of the relevant category;

2.3.1.3. the rated wattage; this need not to be indicated separately if it is part of the international designation of the relevant category;

2.3.1.4. a space of sufficient size to accommodate the approval mark.

2.3.2. The space mentioned in paragraph 2.3.1.4 shall be indicated in the drawings accompanying the application for approval.

2.3.3. Other inscriptions than those covered by paragraphs 2.3.1 and 2.4.4 may be affixed on the cap.

2.4. Approval

2.4.1. If all samples of a type of gas-discharge light source which are submitted in accordance with paragraphs 2.2.2.3 or 2.2.3.2 comply with the requirements of this Regulation, when tested with the ballast according to paragraph 2.2.2.4 in case the ballast is not integrated with the light source, approval shall be granted.

2.4.2. An approval code shall be assigned to each type approved. Its first character shall indicate the series of amendments incorporating the most recent major technical amendments made to the Regulation at the time of issue of the approval.

This will be followed by an identification code comprising not more than three characters. Only the Arabic numerals and capital letters listed in footnote (2) shall be used.

The same Contracting Party may not assign the same code to another type of gas-discharge light source. If the applicant so desires the same approval code may be assigned to both gas-discharge light sources emitting white and selective yellow light (see paragraph 2.1.2).

2.4.3. Notice of approval or of extension or refusal or withdrawal of approval or production definitely discontinued of a type of gas-discharge light source pursuant to this Regulation shall be communicated to the Parties of the Agreement which apply this Regulation by means of a form conforming to the model in Annex 2 to this Regulation and of a drawing, supplied by the applicant for approval in a format not exceeding A4 (210 × 297 mm) and on a scale of at least 2:1.

ANNEX 2

ANNEX 3 EXAMPLE OF THE ARRANGEMENT OF THE APPROVAL MARK (see paragraph 2.4.4) 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 the approval code 0A01. 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 °C ± 5 °C. 2. BALLAST In the case the ballast is not integrated with the light source, all tests and measurements shall be carried out with the ballast as per paragraph 2.2.2.4 of this Regulation. The power supply used for the starting and run-up tests shall be qualified to secure the quick rise of the high current pulse. 3. BURNING POSITION The burning position shall be horizontal within ± 10° 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 32 mm and a length of 60 mm concentric with the reference axis and symmetric to the arc. Moreover stray magnetic fields shall be avoided. 4. AGEING All tests shall be carried out with light sources which have been aged for a minimum of 15 cycles having the following switching cycle: 45 minutes on, 15 seconds off, 5 minutes on, 10 minutes off. 5. SUPPLY VOLTAGE All tests shall be carried out at test voltage as indicated on the relevant data sheet. 6. STARTING TEST The starting test shall be applied to light sources which have not been aged and have not been used for a period of at least 24 hours prior to the test. 7. RUN-UP TEST The run-up test shall be applied to light sources which have not been used for a period of at least 1 hour prior to the test. 8. HOT-RESTRIKE TEST The light source shall be started and be operated with the ballast (possibly integrated) at test voltage for a period of 15 minutes. Then the supply voltage to the ballast or the light source with the ballast integrated shall be switched off for a switch-off period as indicated on the relevant data sheet and be switched on again. 9. ELECTRICAL AND PHOTOMETRIC TEST Before any measurement, the light source shall be stabilised for a period of 15 minutes. 10. COLOUR The colour of the light source shall be measured in an integrating sphere using a measuring system which shows the CIE chromaticity coordinates of the received light with a resolution of ± 0,002. The following figure shows the colour tolerance area for colour white and the restricted tolerance area for the gas-discharge light sources D1R, D1S, D2R, D2S, D3R, D3S, D4R, D4S, D5S, D6S and D8S.

ANNEX 5 OPTICAL SET-UP FOR THE MEASUREMENT OF THE POSITION AND FORMOF THE ARC AND OF THE POSITION OF THE ELECTRODES (1) The gas-discharge light source shall be positioned as shown: in Figure 1 or Figure 2 on sheet DxR/1 or sheet DxS/1 in Figure 3 or Figure 4 on sheet DxR/2 or sheet DxS/2. An optical system shall project a real image A' of the arc A with a magnification of preferably M = s'/s = 20 on a screen. The optical system shall be aplanatic and achromatic. In the focus-length f of the optical system a diaphragm d shall cause a projection of the arc with nearly parallel observation directions. To get the angle of the half divergence not larger than μ = 0,5° the diameter of the focus-diaphragm with respect to the focus-length of the optical system shall be not more than d = 2f tan(μ). The active diameter of the optical system shall be not more than: . (c, b1 and b2 are given on sheet DxS/5, respectively sheet DxR/5). A scale on the screen shall enable to measure the position of the electrodes. The calibration of the arrangement advantageously can be done by using a separate projector with a parallel beam in connection with a gauge whose shadow is projected to the screen. The gauge shall show the reference axis and the plane parallel to the reference plane and at distance ‘e’ mm from it (e = 27,1 for D1R, D1S, D2R, D2S, D3R, D3S, D4R and D4S). In the plane of the screen a receiver has to be mounted movable in a vertical direction on a line corresponding to the plane at ‘e’ from the reference plane of the gas-discharge light source. The receiver shall have the relative spectral sensitivity of the human eye. The size of the receiver shall be not more than 0,2 M mm in the horizontal and not more than 0,025 M mm in the vertical direction (M = the magnification). The range of measurable movement shall be such that the required measures of the arc bending r and arc diffusion s can be measured. (1) This method is an example of a measurement method; any method with equivalent measurement accuracy may be used.

ANNEX 6 MINIMUM REQUIREMENTS FOR QUALITY CONTROL PROCEDURES BY THE MANUFACTURER 1. GENERAL The conformity requirements shall be considered satisfied from a photometric (including UV radiation), geometrical, visual and electrical standpoint if the specified tolerances for production gas-discharge light sources in the relevant data sheet of Annex 1 and the relevant data sheet for the caps are met. 2. MINIMUM REQUIREMENTS FOR VERIFICATION OF CONFORMITY BY THE MANUFACTURER For each type of gas-discharge light source the manufacturer or the holder of the approval mark shall carry out tests, in accordance with the provisions of this Regulation, at appropriate intervals. 2.1. Nature of tests Tests of conformity of these specifications shall cover their photometric, geometrical and optical characteristics. 2.2. Methods used in tests 2.2.1. Tests shall generally be carried out in accordance with the methods set out in this Regulation. 2.2.2. The application of paragraph 2.2.1 requires regular calibration of test apparatus and its correlation with measurements made by a competent authority. 2.3. Nature of sampling Samples of gas-discharge light sources shall be selected at random from the production of a uniform batch. A uniform batch means a set of gas-discharge light sources of the same type, defined according to the production methods of the manufacturer. 2.4. Inspected and recorded characteristics The gas-discharge light sources shall be inspected and test results recorded following the grouping of characteristics as listed in Annex 7, Table 1. 2.5. Criteria governing acceptability The manufacturer or the holder of approval is responsible for carrying out a statistical study of the test results in order to meet the specification laid down for verification of conformity of products in paragraph 4.1 of this Regulation. Compliance shall be assured if the level of acceptable non-compliance per grouping of characteristics given in Table 1 of Annex 7 is not exceeded. This means that the number of gas-discharge light sources not complying with the requirement for any grouping of characteristics of any gas-discharge light source type does not exceed the qualifying limits in the relevant Tables 2, 3 or 4 of Annex 7. Note: Each individual gas-discharge light source requirement shall be considered as a characteristic.
