PROPOSAL FOR SUPPLEMENT 8 TO THE 01 SERIES OF
REGULATION NO. 123
(ADAPTIVE FRONT-LIGHTING SYSTEMS (AFS))
ADOPTED AT THE 171 SESSION – MARCH 2017
PROVISIONAL DATE OF ENTRY INTO FORCE: OCTOBER 10, 2017
Paragraph 5.7.3., amend to read:
"5.7.3. In the case of failure it must be possible to obtain automatically a passing beam or a state
with respect to the photometric conditions which yields values not exceeding 1,300cd in the
zone III b as defined in Annex 3 to this Regulation and at least 3,400cd in a point of
"segment I ", by such means as e.g. switching off, dimming, aiming downwards, and/or
When performing the tests to verify compliance with these requirements, the Technical
Service responsible for approval tests shall refer to the instructions supplied by the
Paragraph 6.2.4., amend to read:
"6.2.4. When emitting a specified mode of the passing beam, the system shall meet the
requirements in the respective section (C, V, E, W) of part A of Table 1 (photometric values)
and in Table 2 I and "cut-off" positions) of Annex 3 to this Regulation, as well as
Section 1 ("cut-off" requirements) of Annex 8 to this Regulation."
Paragraph 188.8.131.52., amend to read:
"184.108.40.206. If approval is sought for a category 1 bending mode, the system is designed so that, in the
case of a failure affecting the lateral movement or modification of the illumination, it must be
possible to obtain automatically either photometric conditions corresponding to
Paragraph 6.2.4. above or a state with respect to the photometric conditions which yields
values not exceeding 1,300cd in the Zone IIIb, as defined in Annex 3 to this Regulation, and
at least 3,400cd in a point of "segment I ";"
Paragraph 220.127.116.11, amend to read:
"18.104.22.168. Passing beam: points B50L and 75R, or 50R if applicable;
Driving beam: I and point HV (percentage of I );"
Table 2, amend to read:
Passing Beam Elements Angular Position/Extend, Additional Requirements
Introductory Part, amend to read:
"Tests for Stability of Photometric Performance of Systems in Operation - Tests on Complete
Tests on Complete Systems
Once the photometric values have been measured according to the prescriptions of this Regulation, in
the point of I for driving beam and in points 25L, 50V and B50L (or R), whichever applies for passing
beam, a complete system sample shall be tested for stability of photometric performance in operation.
Paragraph 22.214.171.124., amend to read:
"126.96.36.199. For a system or parts thereof with the outside lens in plastic material, the mixture of water
and polluting agent to be applied to the test sample shall be composed of:
9 parts by weight of silica sand with a particle size of 0-100μm,
1 part by weight of vegetal carbon dust produced from beech wood with a particle
size of 0-100μm,
(c) 0.2 part by weight of NaCMC ,
(d) 5 parts by weight of sodium chloride (pure at 99%),
Paragraph 188.8.131.52., amend to read:
"184.108.40.206. For the following values of the passing beam and its modes, the maximum unfavourable
deviation may be respectively:
(a) Maximum values at point B50L 170cd equivalent 20% and 255cd equivalent 30%;
Maximum values at Zone III and segment BLL: 255cd equivalent 20% and 380cd
Maximum values at segments E, F1, F2 and F3: 170cd equivalent 20% and 255cd
(d) Minimum values at BR, P, at the groups S 50 + S 50LL + S 50RR, S 100 + S 100LL +
S 100RR, and those required by Footnote of Table 1 in Annex 3 of this Regulation
(B50L, BR, BRR, BLL): half of the required value equivalent 20% and three quarter of
the required value equivalent 30%."
Paragraph 2.4., amend to read:
"2.4. Measured and Recorded Photometric Characteristics
The sampled headlamps shall be subjected to photometric measurements at the points
provided for in the Regulation, the reading being limited:
To points I , HV , "HL" and "HR" in the case of a driving beam,
To points B50L, 50L, 50V, 75R if applicable, and 25LL in the case of the passing beam(s)
(see Figure 1 in Annex 3)."
Paragraph 220.127.116.11., amend to read:
Photometric measurements shall be carried out on the samples before and after the test.
These measurements shall be made according to Annex 9 to this Regulation, at the
B50L and 50V for the class C passing beam lighting;
I for the driving beam of a system."
Paragraph 18.104.22.168., amend to read:
After the test, the results of photometric measurements carried out on the system or part
thereof in accordance with this Regulation shall not exceed by more than 30% the maximum
values prescribed at point B50L and not be more than 10% below the minimum values
prescribed at point 75R, if applicable."
