Specific Technical Requirements. 5.1. Technical requirements concerning driving-beam of the Class A, B, D (GDL), BS, CS, DS or ES (GDL) (symbols “R”, "HR", “DR”, "XR”, "R-BS”, “▇▇-▇▇”, “▇▇-▇▇” or “WR-ES”) 5.1.1. In the case of a road illumination device designed to provide a driving-beam and a passing-beam, measurements of the luminous intensity of the driving-beam shall be taken with the same alignment as for measurements under paragraphs 5.2. to 5.4. In the case of a road illumination device providing a driving-beam only, it shall be so adjusted that the area of maximum luminous intensity is centred on the point of intersection of lines H-H and V-V; such a device needs to meet only the requirements referred to in paragraph 5.1.3. For devices where more than one light source is used to provide the driving-beam, these light sources shall be operated simultaneously to determine the maximum value of the luminous intensity (IM). It is also possible that a part of the driving beam produced by one of these light sources will be used exclusively for short time signals "flash to pass" as declared by the applicant. This shall be indicated in the relevant drawing and a remark shall be made in the communication form. 5.1.2. Irrespective of the type of light source used to produce the principal passing-beam, several light sources are allowed to be used for each individual driving-beam. 5.1.3. Requirements for the luminous intensity distribution of the driving-beams: 5.1.3.1. Referring to Figure A4-II the luminous intensity distribution of the driving-beam shall meet the following requirements. Table 5 Luminous intensity requirements for driving-beam Class A Headlamp Class B Headlamp Class D Headlamp IM 27,000 40,500 43,800 5.1.3.2. Referring to Figure A4-III the luminous intensity distribution of a primary driving-beam shall meet the following requirements. Table 6 Test point number Test point angular coordinates - degrees* Required luminous intensity [cd] 1 H-V 16,000 --- 20,000 --- 30,000 --- 2 H-2.5°R and 2.5°L 9,000 --- 10,000 --- 20,000 --- 3 H-5°R and 5°L 2,500 --- 3,500 --- 5,000 --- 4 H-9°R and 9°L --- --- 2000 --- 3,400 --- 5 H-12°R and 12°L --- --- 600 --- 1,000 --- 6 2°U-V --- --- 1000 --- 1,700 --- MIN luminous intensity of the maximum (IM) 20,000 --- 25,000 --- 40,000 --- MAX luminous intensity of the maximum (IM) --- 215,000 --- 215,000 --- 215,000 * 0.25 tolerance allowed independently at each test point for photometry unless indicated otherwise. 5.1.3.3. Referring to Figure A4-IV the luminous intensity distribution of a secondary driving-beam shall meet the following requirements. Table 7 1 H-V 16,000 --- 20,000 --- 30,000 --- 2 H-2.5°R and 2.5°L 9,000 --- 10,000 --- 20,000 --- 3 H-5°R and 5°L 2,500 --- 3,500 --- 5,000 --- 6 2°U-V --- --- 1,000 --- 1,700 --- MIN luminous intensity of the maximum (IM) 20,000 --- 25,000 --- 40,000 --- MAX luminous intensity of the maximum (IM) --- 215,000 --- 215,000 --- 215,000 * 0.25 tolerance allowed independently at each test point for photometry unless indicated otherwise. 5.1.3.4. Except for classes BS, CS, DS and ES, the point of intersection (HV) of lines h h and v v shall be situated within the isocandela 80 per cent of maximum luminous intensity (Imax) 5.1.3.5. The maximum value (IM) shall in no circumstances exceed 215,000 cd. 5.1.3.6. The reference ▇▇▇▇ (I′M) of the maximum luminous intensity shall be obtained by the ratio: I′M = IM /4,300 This value shall be rounded off to the value 5 - 7.5 - 10 - 12.5 - 17.5 - 20 - 25 - 27.5 - 30 - 37.5 - 40 - 45 - 50. 5.2. Technical requirements concerning headlamps to provide a passing-beam of the Class A, B and D (GDL) (symbols “C”, “HC” and “DC”) 5.2.1. The headlamp shall be aimed according to Annex 5, paragraph 1.2. If, however, vertical adjustment cannot be performed repeatedly to the required position within the allowed tolerances, the instrumental method of Annex 5, paragraph 2. shall be applied to test compliance with the required minimum quality of the "cut-off" line and to perform the beam vertical adjustment. 5.2.1.1. When so aimed, the headlamp shall: (i) If its approval is sought solely for provision of a passing-beam0, comply with the requirements set out in paragraph 5.2.2.; (ii) If it is intended to provide both a passing-beam and a driving-beam, comply with the requirements set out in paragraphs 5.2.2. and 5.1. 5.2.1.2. Where a headlamp so aimed does not meet the requirements set out in paragraphs 5.2.2. and 5.1., its alignment may be changed according to the provisions in Annex 5, paragraph 1.2.3. 5.2.2. The passing-beam shall meet the luminous intensities at the test points referred to in Table 8 and in Figures A4-V or A4-VI. Passing-beam headlamps with gas-discharge light sources shall meet these luminous intensities only after more than 10 minutes after ignition.
