Trade name or mark; [\\[1/\\]](#_ftn1)\n\n2.1.2.2. Bulb design, in so far as these differences affect the optical results;\n\n2.1.2.3. Bulb colour. A yellow bulb or an additional yellow outer bulb, solely intended to change the colour but not the other characteristics of a gas-discharge light source emitting white light, does not constitute a change of type of the gas-discharge light source.\n\n2.2. Application for approval\n\n2.2.1. Application for approval shall be submitted by the owner of the trade name or mark, or by his duly accredited representative.\n\n2.2.2.

A declaration by the manufacturer that the type submitted is (except in the trade name or mark) identical to and has been produced by the same manufacturer as the type already approved, the latter being identified by its approval code;\n\n2.2.3.2. Two samples bearing the new trade name and mark.\n\n2.2.4. The competent authority shall verify the existence of satisfactory arrangements for ensuring effective control of the conformity of production before type approval is granted.\n\n2.3. Inscriptions\n\n2.3.1. Gas-discharge light sources submitted for approval shall bear on the cap:\n\n2.3.1.1. The trade name or mark of the applicant;\n\n2.3.1.2. The international designation of the relevant category;\n\n2.3.1.3. The rated wattage; this need not be indicated separately if it is part of the international designation of the relevant category;\n\n2.3.1.4. A space of sufficient size to accommodate the approval mark.\n\n2.3.2. The space mentioned in paragraph 2.3.1.4. shall be indicated in the drawings accompanying the application for approval.\n\n2.3.3. Other inscriptions than those covered by paragraphs 2.3.1. and 2.4.4. may be affixed on the cap.\n\n2.3.4. The ballast used for the type approval of the light source shall be marked with type and trade mark identification and with the rated voltage and wattage, as indicated on the relevant lamp data sheet.\n\n2.4. Approval\n\n2.4.1. 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., approval shall be granted.\n\n2.4.2. 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.\n\nThis will be followed by an identification code comprising not more than two characters. Only the Arabic numerals and capital letters listed in footnote [\\[2/\\]](#_ftn2) shall be used.\n\nThe 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 the gas-discharge light sources emitting white and yellow light (see paragraph 2.1.2.3.).\n\n2.4.3. 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 x 297mm) and on a scale of at least 2 : 1.\n\n2.4.4. To every gas-discharge light source conforming to a type approved under this Regulation there shall be affixed in the space referred to in paragraph 2.3.1.4., in addition to the inscription required under paragraph 2.3.1., an international approval mark consisting of:\n\n2.4.4.1. A truncated circle surrounding the letter 'E' followed by the distinguishing number of the country granting approval; [\\[3/\\]](#_ftn3)\n\n2.4.4.2. The approval code, placed close to the truncated circle.\n\n2.4.5. If the applicant has obtained the same approval code for several trade names or marks, one or more of them will suffice to meet the requirements of paragraph 2.3.1.1.\n\n2.4.6. The marks and inscriptions specified in paragraphs 2.3.1. and 2.4.3. shall be clearly legible and indelible.\n\n2.4.7. Annex 3 to this Regulation gives an example of a type of approval mark.\n\n3.

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.\n\nAnnex 4\n\nMETHOD OF MEASUREMENT OF ELECTRICAL AND PHOTOMETRIC CHARACTERISTICS\n\n1. General\n\nFor 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.\n\n2. Ballast\n\nAll 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.\n\n3. Burning position\n\nThe 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.\n\n4. Ageing\n\nWith the exception of the starting test, 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.\n\n5. Supply voltage\n\nAll tests shall be carried out at test voltage as indicated on the relevant data sheet.\n\n6. Starting test\n\nThe 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.\n\n7. Run-up test\n\nThe 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.\n\n8. Hot restrike test\n\nThe light source shall be started and be operated with the ballast at test voltage for a period of 15 minutes. The supply voltage to the ballast shall then be switched off for a switch-off period as indicated on the relevant data sheet, and be switched on again.\n\n \n\n9. Electrical and photometric test\n\nBefore any measurement, the light source shall be stabilized for a period of 15 minutes.\n\n10. Colour\n\nThe colour of the light source shall be measured in an integrating sphere using a measuring system which shows the CIE chromaticity co-ordinates 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 DlS, D2S AND D2R.\n\n![Figure is of a graph showing the colour tolerance area for colour white and the restricted tolerance area for the gas discharge light sources](image.021.png)\n\nAnnex 5\n\nOPTICAL SETUP FOR THE MEASUREMENT OF THE POSITION AND FORM OF THE ARC AND OF THE POSITION OF THE ELECTRODES [\\[1/\\]](#_ftn15)\n\nThe gas-discharge light source shall be positioned as shown in figure 1 on sheet DlS/D2S/1 respectively sheet D2R/l.\n\n![Figure shows the position of a gas discharge light source ](image.022.png)\n\nAn 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 mu = 0.5 degrees the diameter of the focus-diaphragm with respect to the focus-length of the optical system shall be not more than d = 2f tan (mu).\n\nThe active diameter of the optical system shall be not more than:\n\nD = (1 + 1/M)d + c + (bl + b2)/2. (c, bl and b2 are given on sheet DlS/D2S/4 respectively sheet D2R/4).\n\nA scale on the screen shall enable measurement of 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 DlS, D2S and D2R).\n\nIn 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.\n\nThe receiver shall have the relative spectral sensitivity of the human eye. The size of the receiver shall be not more than 0.2Mmm in the horizontal direction and not more than 0.025Mmm in the vertical direction. (M = the magnification.) The range of the measurable movement shall be such that the required measures of the arc bending r and arc diffusion s can be measured.\n\nAnnex 6\n\nMINIMUM REQUIREMENTS FOR QUALITY CONTROL PROCEDURES BY THE MANUFACTURER\n\n1. GENERAL\n\nThe 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.\n\n2. MINIMUM REQUIREMENTS FOR VERIFICATION OF CONFORMITY BY THE MANUFACTURER\n\nFor 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.\n\n2.1. Nature of tests\n\nTests of conformity of these specifications shall cover their photometrical, geometrical and optical characteristics.\n\n2.2. Methods used in tests\n\n2.2.1. Tests shall generally be carried out in accordance with the methods set out in this Regulation.\n\n2.2.2. The application of paragraph 2.2.1. requires regular calibration of test apparatus and its correlation with measurements made by a competent authority.\n\n2.3. Nature of sampling\n\nSamples 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.\n\n2.4. Inspected and recorded characteristics\n\nThe gas-discharge light sources shall be inspected and test results recorded following the grouping of characteristics as listed in annex 7, table 1.\n\n2.5. Criteria governing acceptability\n\nThe manufacturer or the holder of the approval is responsible for carrying out a statistical study of the test results in order to meet the specifications 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.\n\nNote: Each individual gas-discharge light source requirement shall be considered as a characteristic.\n\nAnnex 7\n\nSAMPLING AND COMPLIANCE LEVELS FOR MANUFACTURER TEST RECORDS\n\nTable 1 - Characteristics\n\n| Grouping of characteristics | Grouping [*/] of test records between gas-discharge light source types | Minimum 12 monthly sample per grouping*/ | Acceptable level of non- compliance dischargecharacteristics (%) |\n| ------------------------------------------ | ---------------------------------------------------------------------- | ---------------------------------------- | ---------------------------------------------------------------- |\n| Marking, legibility and durability | All types with the same external dimensions | 315 | 1 |\n| Bulb quality | All types with the same bulb | 315 | 1 |\n| External dimensions (excluding cap) | All types of the same category | 315 | 1 |\n| Position and dimensions of arc and stripes | All types of the same category | 200 | 6.5 |\n| Starting, run-up and hot- restrike | All types of the same category | 200 | 1 |\n| Lamp voltage and wattage | All types of the same category | 200 | 1 |\n| Luminous flux, colour and UV-radiation | All types of the same category | 200 | 1 |\n\nTable 2\n\nQualifying limits for acceptance based on different numbers of test results for each grouping of characteristics are listed in table 2 as maximum number of non- compliances.
