3. TECHNICAL REQUIREMENTS
3.1. Definitions
The definitions given in Resolution R.E.5 or its subsequent revisions, applicable at the time
of application for type approval shall apply.
3.2. General Specifications
3.2.1. Each sample submitted shall conform to the relevant specifications of this Regulation.
3.2.2. Filament light sources 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) shall be the only element(s) of the filament light source that generate and
emit light when energised.
3.3. Manufacture
3.3.1. Filament light source bulbs shall exhibit no scores or spots which might impair their
efficiency and their optical performance.
3.3.2. Filament light sources shall be equipped with standard caps complying with the cap data
sheets of IEC Publication 60061, as specified on the individual data sheets of Annex 1.
3.3.3. The cap shall be strong and firmly secured to the bulb.
3.3.4. To ascertain whether filament light sources conform to the requirements of
Paragraphs 3.3.1. to 3.3.3. above, a visual inspection, a dimension check and, where
necessary, a trial fitting shall be carried out.
3.4. Tests
3.4.1. Filament light sources shall first be aged at their test voltage for approximately one hour. For
dual-filament light sources, each filament shall be aged separately. In the case of filament
light sources, for which more than one test voltage is specified, the highest test voltage
value shall be used for ageing.
3.4.2. In the case of a filament light source having a coated bulb, after the ageing period
corresponding to Paragraph 3.4.1. the surface of the bulb shall be lightly wiped with a cotton
cloth soaked in a mixture of 70% volume of n-heptane and 30% volume of toluol. After about
5min, the surface shall be inspected visually. It shall not show any apparent changes.
3.4.3. The position and dimensions of the filament shall be measured with the filament light
sources being supplied with current at from 90% to 100% of the test voltage. In the case of
filament light sources, for which more than one test voltage is specified, the highest test
voltage value shall be used for measurement of the position and dimensions of the filament.
3.4.4. Unless otherwise specified, electrical and photometric measurements shall be carried out at
the test voltage(s).

3.7. UV Radiation
The UV radiation of a halogen light source shall be such that:
K1 =
k



Ee ( λ)
⋅ dλ
Ee ( λ)
⋅ V( λ)


≤ 2 ⋅ 10
W/ lm
K2 =
k



Ee ( λ)
⋅ dλ
Ee ( λ)
⋅ V( λ)
⋅ dλ
≤ 2 ⋅10
W/ lm
Where:
Ee (λ)
(W/nm)
is the spectral distribution of the radiant flux;
V (λ)
(l)
is the spectral luminous efficiency;
k = 683
(lm/W)
is the photometric radiation equivalent;
λ
(nm)
is the wave length
This value shall be calculated using intervals of five nanometres.
3.8. Observation Concerning Selective-Yellow Colour
An approval of a filament light source type under this Regulation may be granted, pursuant
to Paragraph 3.6. above, for a filament light source emitting white light as well as
selective-yellow light; Article 3 of the Agreement to which this Regulation is annexed shall
not prevent the Contracting Parties from prohibiting, on vehicles registered by them, filament
light sources emitting either white or selective-yellow light.
3.9. Check on Optical Quality
(Applies only to filament light sources with an internal shield to produce the cut-off).
3.9.1. This check of optical quality shall be carried out at a voltage such that the measuring
luminous flux is obtained; the specifications of Paragraph 3.4.6. are to be observed
accordingly.
3.9.2. For 12V Filament Light Sources Emitting White Light:
The sample which most nearly conforms to the requirements laid down for the standard
filament light source 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 light source being tested meets the light-distribution requirements laid down for the
passing-beam in the relevant Regulation.

4.3. The holder of the approval shall in particular:
4.3.1. Ensure existence of procedures for the effective control of the quality of products,
4.3.2. Have access to the control equipment necessary for checking the conformity to each
approved type,
4.3.3. Ensure that data of test results are recorded and that related documents shall remain
available for a period to be determined in accordance with the Type Approval Authority;
4.3.4. Analyse the results of each type of test, applying criteria of Annex 7, in order to verify and
ensure the stability of the product characteristics making allowance for variation of an
industrial production,
4.3.5. Ensure that for each type of filament light source, at least the tests prescribed in Annex 6 to
this Regulation are carried out,
4.3.6. Ensure that any collecting of samples giving evidence of non-conformity with the type of test
considered shall give rise to another sampling and another test. All the necessary steps
shall be taken to re-establish the conformity of the corresponding production.
4.4. The Type Approval Authority which has granted type-approval may at any time verify the
conformity control methods applicable to each production unit.
4.4.1. In every inspection, the test books and production survey records shall be presented to the
visiting inspector.
4.4.2. The inspector may take samples at random which will be tested in the manufacturer's
laboratory. The minimum number of samples may be determined according to the results of
the manufacturer's own verification.
4.4.3. When the quality level appears unsatisfactory or when it seems necessary to verify the
validity of the tests carried out in application of Paragraph 4.4.2. above, the inspector shall
select samples, to be sent to the Technical Service which has conducted the type approval
tests.
4.4.4. The Type Approval Authority may carry out any tests prescribed in this Regulation. Where
the Type Approval Authority decides to carry out spot checks, criteria of Annexes 8 and 9 to
this Regulation shall be applied.
4.4.5. The normal frequency of inspections authorised by the Type Approval Authority shall be one
every two years. In the case where negative results are recorded during one of these visits,
the Type Approval Authority shall ensure that all necessary steps are taken to re-establish
the conformity of production as rapidly as possible.
5. PENALTIES FOR NON-CONFORMITY OF PRODUCTION
5.1. The approval granted in respect of a filament light source pursuant to this Regulation may
be withdrawn if the requirements are not met or if a filament light source bearing the
approval mark does not conform to the type approved.

ANNEX 8
MINIMUM REQUIREMENTS FOR SPOT CHECKS BY THE TYPE APPROVAL AUTHORITY
1. GENERAL
The conformity requirements shall be considered satisfied from a photometric, geometrical,
visual and electrical standpoint if the specified tolerances for production filament light sources in
the relevant data sheet of Annex 1 and the relevant data sheet for the caps are met.
2. The conformity of mass-produced filament light sources shall not be contested if the results are
in agreement with Annex 9 to this Regulation.
3. Conformity shall be contested and the manufacturer requested to make the production meet the
requirements if the results are not in agreement with Annex 9 to this Regulation.
4. If Paragraph 3 of this Annex is applied, a further sample of 250 filament light sources, selected at
random from a recent production run, shall be taken within two months.
