to the introduction of two new definitions of“reference luminous flux” and“objective luminous flux” into Regulation No. 48.
Disconnection of the electronic light source control gear for photometric measurements is moved from paragraph 5.3.1.3. to paragraph 6.1.3. because the disconnection is only necessary for photometric measurements at reference luminous flux.
During the checking, the voltage at the terminals of the filament lamp shall be regulated so as to obtain the reference luminous flux at 13.2V as indicated at the relevant data sheet of Regulation No. 37.
For filament lamps the correction factor is the ratio between the reference luminous flux and the mean value of the luminous flux found at the voltage applied 6.75 V,
In a case that for a category of filament lamp more than one value of reference luminous flux is specified, the value at approximately 12 V for approval of a lighting device
at the necessary voltage to produce the reference luminous flux required for that category of filament lamp;
filament lamp during the process of photometric measurement it is permissible to carry out the measurements at a luminous flux that differs from the reference luminous flux at 13.2V. If the test laboratory chooses to carry out measurements in such a manner the luminous intensity shall be corrected by multiplying the measured value by the individual factor F lamp of the standard(étalon)
filament lamp during the process of photometric measurement it is permissible to carry out the measurements at a luminous flux that differs from the reference luminous flux at 13.2 V. If the Technical Service chooses to carry out measurements in such a manner,
Since the emitted luminous flux at the same voltage is different per light source, since the reference luminous flux is fixed and the voltage at which this flux is achieved is known, it is proposed to continue photometric measurements at reference luminous flux and calculate the effects of the electronic light source control gear for all three voltage systems, including the dual reference flux option of H9 and H9B.
filament lamp during the process of photometric measurement it is permissible to carry out the measurements at a luminous flux that differs from the reference luminous flux at 13.2 V. If the test laboratory chooses to carry out measurements in such a manner the luminous intensity shall be corrected by multiplying the measured value by the individual factor Flamp of the standard(étalon)
Until 9 December 2015 with regard to the changes introduced by the 04 series of amendments concerning the photometric testing at reference luminous flux at approximately 13.2 volts,
Reference luminous flux White: 350 lm.
Amber Reference luminous flux at approximately 13.5 V.

Reference luminous flux: 280 lm
Reference luminous flux in lm at test voltage of 13.5V DC 6/.
Replace"Reference luminous flux" by"objective luminous flux"
Φ reference is the reference luminous flux at 13,2V as specified in the relevant data sheet of Regulation 37.
