2.3.1.3. The international designation of the relevant category. The wattage character "W" of this
designation need not be marked when the maximum allowed bulb diameter of the filament
lamp type does not exceed 7.5mm;
2.3.1.4. The rated wattage (in the sequence, high wattage/low wattage filament for dual-filament
lamps); this need not be indicated separately if it is part of the international designation of
the relevant filament lamp category;
2.3.1.5. A space of sufficient size to accommodate the approval mark.
2.3.2. The space mentioned in Paragraph 2.3.1.5. above shall be indicated in the drawings
accompanying the application for approval.
2.3.3. Halogen filament lamps meeting the requirements of Paragraph 3.7. below shall be marked
with a "U".
2.3.4. Inscriptions other than those covered by Paragraphs 2.3.1. and 2.4.3. may be affixed, on the
condition that they do not adversely affect the luminous characteristics.

3. TECHNICAL REQUIREMENTS
3.1. Definitions
3.1.1. Rated voltage: voltage (in volts) marked on the filament lamp;
3.1.2. Rated wattage: wattage (in watts) marked on the filament lamp which may be incorporated
into the international designation of the relevant category;
3.1.3. Test voltage: voltage, at the filament lamp terminals for which the electrical and photometric
characteristics of the filament lamp are intended and are to be tested;
3.1.4. Objective values: values to be achieved, within the specified tolerances, when the filament
lamp is supplied with current at its test voltage;
3.1.5. Standard (étalon) filament lamp: a filament lamp emitting white or amber or red light with
reduced dimensional tolerances, used for the photometric testing of lighting and
light-signalling devices. Standard filament lamps are specified in only one voltage rating for
each category;
3.1.6. Reference luminous flux: specified luminous flux of a standard filament lamp to which the
optical characteristics of a lighting device shall be referred;
3.1.7. Measuring luminous flux: specified value of the luminous flux for testing a filament lamp in
the standard headlamp as specified in Paragraph 3.9;
3.1.8. Reference axis: an axis defined with reference to the cap and to which certain dimensions of
the filament lamp are referred;
3.1.9. Reference plane: a plane defined with reference to the cap and to which certain dimensions
of the filament lamp are referred.
3.1.10. Filament light source (filament lamp): a light source where the element for visible radiation is
one or more heated filaments producing thermal radiation.
3.2. General Specifications
3.2.1. Each sample submitted shall conform to the relevant specifications of this Regulation.
3.2.2. Filament lamps shall be so designed as to be and to remain in good working order when in
normal use. They shall moreover exhibit no fault in design or manufacture.
3.2.3. The filament(s) as specified in the data sheet of the relevant category in Annex 1 shall be
the only element(s) of the filament lamp that generate and emit light when energised.

3.5.4. The length of a line filament shall be determined by its ends, defined – unless otherwise
specified on the relevant data sheet - as the apices of the first and the last filament turn as
seen in projection perpendicular to the reference axis of the filament lamp. Such an apex
shall comply with the requirement that the angle formed by the legs shall not exceed 90°. In
the case of coiled-coil filaments the apices of the secondary turns shall be taken into
account. Apices outside the point of connection to the current lead-in legs shall be
disregarded for the determination of the filament length.
3.5.4.1. For axial filaments the extreme position of the apices considered shall be determined by
rotating the filament lamp about its reference axis. The length shall then be measured in a
direction parallel to the reference axis.
3.5.4.2. For transverse filaments the filament axis shall be placed perpendicular to the direction of
projection. The length shall be measured in a direction perpendicular to the reference axis.
3.6. Colour
3.6.1. The colour of the light emitted by the filament lamp shall be white unless otherwise specified
on the relevant data sheet.
3.6.2. The definitions of the colour of the light emitted, given in Regulation No. 48 and its series of
amendments in force at the time of application for type approval, shall apply to this
Regulation.
3.6.3. The colour of the light emitted shall be measured by the method specified in Annex 5. Each
measured value shall lie within the required tolerance area. Moreover, in the case of
filament lamps emitting white light, the measured values shall not deviate more than
0.020 units in the x and/or y direction from a point of choice on the Planckian locus
(CIE 015:2004, 3rd Edition). Filament lamps for use in light signalling devices shall meet the
requirements as specified in Paragraph 2.4.2 of IEC Publication 60809, Edition 3.

3.9.3. For 6-Volt And 24-Volt Filament Lamps Emitting White Light:
The sample which most nearly conforms to the nominal dimension values shall be tested in
a standard headlamp as specified in Paragraph 3.9.5. and it shall be verified whether the
assembly comprising the aforesaid headlamp and the filament lamp being tested meets the
light-distribution requirements laid down for the passing-beam in the relevant Regulation.
Deviations not exceeding 10% of the minimum values will be acceptable.
3.9.4. Filament lamps emitting selective-yellow light shall be tested in the same manner as
described in Paragraphs 3.9.2. and 3.9.3. in a standard headlamp as specified in
Paragraph 3.9.5. to ensure that the illumination complies with at least 85% for 12V filament
lamps, and at least 77% for 6V and 24V filament lamps, with the minimum values of the
light-distribution requirements laid down for the passing-beam in the relevant Regulation.
The maximum illumination limits remain unchanged.
In the case of a filament lamp having a selective-yellow bulb, this test shall be left out if the
approval is also given to the same type of filament lamp emitting white light.
3.9.5. A Headlamp shall be Deemed to be a Standard Headlamp if:
3.9.5.1. It satisfies the pertinent conditions of approval;
3.9.5.2. It has an effective diameter of not less than 160mm;
3.9.5.3. With a standard filament lamp it produces at the various points and in the various zones
specified for the headlamp type concerned, illumination equal to:
3.9.5.3.1. Not more than 90% of the maximum limits;
3.9.5.3.2. Not less than 120% of the minimum limits prescribed for the headlamp type concerned.
3.10. Standard Filament Lamps
Additional requirements for standard (étalon) filament lamps are given on the relevant data
sheets of Annex 1.
Bulbs of standard (étalon) filament lamps emitting white light shall not alter the
CIE trichromatic coordinates of a luminous source having a colour temperature of 2,856K by
more than 0.010 units in the x and/or y direction.
For standard (étalon) filament lamps emitting amber or red light, changes of the bulb
temperature shall not affect the luminous flux which might impair photometric
measurements of signalling devices.

5. PENALTIES FOR NON-CONFORMITY OF PRODUCTION
5.1. The approval granted in respect of a filament lamp pursuant to this Regulation may be
withdrawn if the requirements are not met or if a filament lamp bearing the approval mark
does not conform to the type approved.
5.2. If a Contracting Party to the Agreement applying this Regulation withdraws an approval it
has previously granted, it shall forthwith so notify the other Contracting Parties applying this
Regulation, by means of a communication form conforming to the model in Annex 2 to this
Regulation.
6. PRODUCTION DEFINITIVELY DISCONTINUED
If the holder of the approval completely ceases to manufacture a type of filament lamp
approved in accordance with this Regulation, he shall so inform the Type Approval Authority
which has granted the approval. Upon receiving the relevant communication, that Type
Approval Authority shall inform thereof the other Parties to the 1958 Agreement applying
this Regulation by means of a communication form conforming to the model in Annex 2 to
this Regulation.
7. NAMES AND ADDRESSES OF THE TECHNICAL SERVICES RESPONSIBLE FOR
CONDUCTING APPROVAL TESTS, AND OF TYPE APPROVAL AUTHORITIES
The Parties to the 1958 Agreement which apply this Regulation shall communicate to the
United Nations Secretariat the names and addresses of the Technical Services responsible
for conducting approval tests and of the Type Approval Authorities which grant approval and
to which forms certifying approval or extension or refusal or withdrawal of approval, or
production definitively discontinued issued in other countries, are to be sent.

TEST PROCEDURES AND REQUIREMENTS
1. The filament lamp is placed in a holder capable of being rotated about its axis and having either a
calibrated scale or fixed stops corresponding to the angular displacement tolerance limits. The
holder is then so rotated that an end view of the filament is seen on the screen on to which the
image of the filament is projected. The end view of the filament shall be obtained within the
angular displacements tolerance limits.
2. Side Elevation
The filament lamp placed with the cap down, the reference axis vertical and the filament seen
end-on, the projection of the filament shall lie entirely within a rectangle of height "a" and width "b",
having its centre at the theoretical position of the centre of the filament.
3. Front Elevation
The filament lamp placed with the cap down and the reference axis vertical, the filament lamp
being viewed in a direction at right angles to the filament axis:
3.1. The projection of the filament shall lie entirely within a rectangle of height "a" and width "h", having
its centre at the theoretical position of the centre of the filament.
3.2. The centre of the filament shall not be offset by more than distance "k" from the reference axis.

This test is used to determine, by checking whether:
Screen Projection Requirements
(a)
(b)
The major (high-wattage) filament is correctly positioned relative to the reference axis and
reference plane and has an axis perpendicular, within ± 15°, to the plane through the centres of
the pins and the reference axis; and whether
The minor (low-wattage) filament is correctly positioned relative to the major (high-wattage)
filament, whether a filament lamp complies with the requirements.
TEST PROCEDURE AND REQUIREMENTS
1. The filament lamp is placed in a holder capable of being rotated about its axis and having either
a calibrated scale or fixed stops corresponding to the angular displacement tolerance limits,
(ie 15°). The holder is then so rotated that an end view of the major filament is seen on the
screen on which the image of the filament is projected. The end view of that filament shall be
obtained within the angular displacement tolerance limits.
2. Side Elevation
The filament lamp placed with the cap down, the reference axis vertical, the reference pin to the
right and the major filament seen end-on:
2.1. The projection of the major filament shall lie entirely within a rectangle of height "a" and width "b"
having its centre at the theoretical position of the centre of the filament.
2.2. The projection of the minor filament shall lie entirely;
2.2.1. Within a rectangle of width "c" and height "d" having its centre at a distance "v" to the right of and
at a distance "u" above the theoretical position of the centre of the major filament;
2.2.2. Above a straight line tangential to the upper edge of the projection of the major filament and
rising from left to right at an angle of 25°;
2.2.3. To the right of the projection of the major filament.
3. Front Elevation
The filament lamp being placed with the cap down and the reference axis vertical, the filament
lamp being viewed in a direction at right angles to axis of the major filament:
3.1. The projection of the major filament shall lie entirely within a rectangle of height "a" and width "h"
centred on the theoretical position of the centre of the filament;
3.2. The centre of the major filament shall not be offset by more than distance "k" from the reference
axis;
3.3. The centre of the minor filament axis shall not be offset from the reference axis by more than
± 2mm (±0.4mm for standard filament lamps).

ANNEX 6
MINIMUM REQUIREMENTS FOR QUALITY CONTROL PROCEDURES
BY THE MANUFACTURER
The conformity requirements shall be considered satisfied from a photometric, geometrical,
visual and electrical standpoint if the specified tolerances for production filament lamps 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 filament lamp 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 Type Approval Authority.
2.3. Nature of Sampling
Samples of filament lamps shall be selected at random from the production of a uniform batch. A
uniform batch means a set of filament lamps of the same type, defined according to the
production methods of the manufacturer.
2.4. Inspected and Recorded Characteristics
The filament lamps 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 specifications laid down for verification of conformity of
production 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
filament lamps not complying with the requirement for any grouping of characteristics of any
filament lamp type does not exceed the qualifying limits in the relevant Table 2, 3 or 4 of
Annex 7.
Note: Each individual filament lamp requirement shall be considered as a characteristic.

Qualifying 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-compliance. The limits are based on an
acceptable level of 1% of non-compliance, assuming an acceptance probability of at least 0.95.
