ANNEX 3
MINIMUM ANGLES REQUIRED FOR THE LIGHT DISTRIBUTION IN SPACE
In all cases, the minimum vertical angles of light distribution in space are 15° above and 15° below the
horizontal except for lamps with a mounting height of equal to or less than 750mm above the ground, for
which they are 15° above and 5° below the horizontal.

2.2. Within the field of light distribution of Paragraph 2, above, schematically shown as a grid,
the light pattern should be substantially uniform in so far as the light intensity in each
direction of a part of the field formed by the grid lines meets at least the lowest minimum
percentage value being shown (available) on the grid lines surrounding the questioned
direction.
2.3. However in the case where a device is intended to be installed with its H Plane at a
mounting height less than 750 mm above the ground, the photometric intensity is verified
only up to an angle of 5° downwards.
3. PHOTOMETRIC MEASUREMENT OF LAMPS
The photometric performance shall be checked:
3.1. For non-replaceable light sources (filament lamps and other):
with the light sources present in the lamp, in accordance with the relevant subparagraph of
Paragraph 8.1. of this Regulation.
3.2. For replaceable light sources:
when equipped with light sources at 6.75V, 13.5V or 28.0V, the luminous intensity values
produced shall be corrected. 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 (6.75V, 13.5V or 28.0V).
For LED light sources the correction factor is the ratio between the objective luminous flux
and the mean value of the luminous flux found at the voltage applied (6.75V, 13.5V or
28.0V).
The actual luminous fluxes of each light source used shall not deviate more than ± 5% from
the mean value. Alternatively and in case of filament lamps only, a standard filament lamp
may be used in turn, in each of the individual positions, operated at its reference flux, the
individual measurements in each position being added together.
3.3. For any signalling lamp except those equipped with filament lamp(s), the luminous
intensities, measured after one minute and after 30min of operation, shall comply with the
minimum and maximum requirements. The luminous intensity distribution after one minute
of operation can be calculated from the luminous intensity distribution after 30min of
operation by applying at each test point the ratio of luminous intensities measured at HV
after one minute and after 30min of operation.

2. MINIMUM REQUIREMENTS FOR VERIFICATION OF CONFORMITY BY THE
MANUFACTURER
For each type of lamp the holder of the approval mark shall carry out at least the following
tests, at appropriate intervals. The tests shall be carried out in accordance with the
provisions of this Regulation.
If any sampling shows non-conformity with regard to the type of test concerned, further
samples shall be taken and tested. The manufacturer shall take steps to ensure the
conformity of the production concerned.
2.1. Nature of Tests
Tests of conformity in this Regulation shall cover the photometric and colorimetric
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. In any test of conformity carried out by the manufacturer, equivalent methods may be used
with the consent of the Type Approval Authority responsible for approval tests. The
manufacturer is responsible for proving that the applied methods are equivalent to those laid
down in this Regulation.
2.2.3. The application of Paragraphs 2.2.1. and 2.2.2. above requires regular calibration of test
apparatus and its correlation with measurements made by a Type Approval Authority.
2.2.4. In all cases the reference methods shall be those of this Regulation, particularly for the
purpose of administrative verification and sampling.
2.3. Nature of Sampling
Samples of lamps shall be selected at random from the production of a uniform batch. A
uniform batch means a set of lamps of the same type, defined according to the production
methods of the manufacturer.
The assessment shall in general cover series production from individual factories. However,
a manufacturer may group together records concerning the same type from several
factories, provided these operate under the same quality system and quality management.
2.4. Measured and Recorded Photometric Characteristics
The sampled lamp shall be subjected to photometric measurements for the minimum values
at the points listed in Annex 4 and the required chromaticity coordinates.
2.5. Criteria Governing Acceptability
The manufacturer is responsible for carrying out a statistical study of the test results and for
defining, in agreement with the competent authority, criteria governing the acceptability of
his products in order to meet the specifications laid down for verification of conformity of
products in Paragraph 12.1. of this Regulation.
The criteria governing the acceptability shall be such that, with a confidence level of 95%,
the minimum probability of passing a spot check in accordance with Annex 6 (first sampling)
would be 0.95.

3. FIRST REPEATED SAMPLING
A sample of four lamps is selected at random from stock manufactured after alignment.
The first sample of two is marked C, the second sample of two is marked D.
3.1. The conformity of mass-produced parking lamps shall not be contested if the deviation of
any specimen of samples C and D (all four lamps) is not more than 20%.
In the case, that the deviation of both lamps of sample C is not more than 0% the
measurement can be closed.
3.2. The conformity of mass-produced parking lamps shall be contested if the deviation of at
least:
3.2.1. One specimen of sample C or D is more than 20% but the deviation of all specimen of these
samples is not more than 30%.
The manufacturer shall be requested again to bring his production in line with the
requirements (alignment).
A second repeated sampling according to Paragraph 4. below shall be carried out within two
months' time after the notification. The samples C and D shall be retained by the Technical
Service until the entire Conformity of Production process is finished.
3.2.2. One specimen of sample C or D is more than 30%.
In this case the approval shall be withdrawn and Paragraph 5. below shall be applied.
4. SECOND REPEATED SAMPLING
A sample of four lamps is selected at random from stock manufactured after alignment.
The first sample of two is marked E, the second sample of two is marked F.
4.1. The conformity of mass-produced parking lamps shall not be contested if the deviation of
any specimen of samples E and F (all four lamps) is not more than 20%.
In the case, that the deviation of both lamps of sample E is not more than 0%, the
measurement can be closed.
4.2. The conformity of mass-produced parking lamps shall be contested if the deviation of at
least one specimen of sample E or F is more than 20%.
In this case the approval shall be withdrawn and Paragraph 5. below shall be applied.
5. APPROVAL WITHDRAWN
Approval shall be withdrawn according to Paragraph 13. of this Regulation.
