PROPOSAL FOR SUPPLEMENT 7 TO THE 01 SERIES OF
AMENDMENTS TO
REGULATION NO. 112
(HEADLAMPS EMITTING AN
ASYMMETRICAL PASSING BEAM)
ADOPTED AT THE 171 SESSION – MARCH 2017
PROVISIONAL DATE OF ENTRY INTO FORCE: OCTOBER 10, 2017

Paragraphs 10.1. to 10.5., amend to read:
"10.1. Headlamps shall be so manufactured as to conform to the type approved under this
Regulation.
The compliance with the requirements set forth in Paragraphs 6. and 7. above shall be
verified as follows:
The minimum requirements for Conformity of Production (CoP) control procedures set forth
in Annex 5 to this Regulation shall be complied with.
The minimum requirements for sampling by an inspector set forth in Annex 7 to this
Regulation shall be complied with.
10.2. The authority which has granted type approval may at any time verify the conformity control
methods applied in each production facility. The normal frequency of these verifications
shall be once every two years.
10.3. Headlamps with apparent defects are disregarded.
10.4. The reference mark is disregarded.
10.5. The measuring test Points 1 to 8 of Paragraph 6.2.4. of this Regulation are disregarded."
Paragraph 10.6., shall be deleted.
Annex 2, Figures 5 to 10, amend to read:
"...
Figure 5 Figure 6
The headlamp bearing the above approval mark is a headlamp incorporating a lens of
plastic material meeting the requirements of this Regulation in respect of the passing-beam
only and is designed:
Figure 5: Class A for Left-hand Traffic Only
Figure 6: Class B for Both Traffic Systems

Annex 3,
Figure B, amend to read:
"
Figure B
Passing-beam for Right-hand Traffic
h-h = horizontal plane,
v-v = vertical plane passing through the optical axis of the headlamp
The test point locations for left-hand traffic are mirrored about the VV line."
Annex 4,
Introductory part, amend to read:
"Tests on Complete Headlamps
Once the photometric values have been measured according to the prescriptions of this
Regulation, in the point for I for driving-beam and in points 25L, 50 R, B 50 L for passingbeam
(or 25R, 50 L, B 50 R for headlamps designed for left-hand traffic) a complete
headlamp sample shall be tested for stability of photometric performance in operation.
"Complete headlamp" shall be understood to mean the complete lamp itself including those
surrounding body parts and lamps which could influence its thermal dissipation.
…"

Annex 5,
Paragraph 1.2.2.1., amend to read:
"1.2.2.1. For the passing-beam, the values prescribed in this Regulation are met at one point within a
circle of 0.35° around points B 50 L (or R) (with a tolerance of 85cd), 75 R (or L), 50 V, 25 R,
25 L, and in the entire area of Zone IV which is not more than 0.52° above line 25 R and
25 L;"
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 at the points I , HV , HL, HR in
the case of a driving-beam, and to points B 50 L (or R), 50L (or R), 50 V, 75 R (or L) and
25 L (or R) in the case of the passing-beam (see Figure in Annex 3)."
Annex 6, Paragraph 2.6.1.2., amend to read:
"2.6.1.2. Results
After the test, the results of photometric measurements carried out on the headlamp in
accordance with this Regulation shall not exceed:
(a)
By more than 30% the maximum values prescribed at points B 50 L and by more than
10% below the minimum values prescribed at point 75 R (in the case of headlamps
intended for left-hand traffic, the points to be considered are B 50 R and 75 L);
or
(b)
By more than 10% below the minimum values prescribed for HV in the case of a
headlamp producing driving-beam only."
Annex 7,
Paragraph 1.2.2.1., amend to read:
"1.2.2.1. For the passing-beam, the values prescribed in this Regulation are met at one point of each
area delimited on the measuring screen (at 25m) by a circle 15cm in radius around points
B 50 L (or R) (with a tolerance of 85cd), 75 R (or L), 50 V, 25 R, 25 L, and in the entire
area of Zone IV which is not more than 22.5cm above line 25 R and 25 L;"

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 headlamps 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 headlamps shall be contested if the deviation of at least
one specimen of samples 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 11. of this Regulation.
6. Change of the Vertical Position of the Cut-off Line
With respect to the verification of the change in vertical positions of the cut-off line under the
influence of heat, the following procedure shall be applied:
One of the headlamps of sample A shall be tested according to the procedure described in
Paragraph 2.1. of Annex 4 after being subjected three consecutive times to the cycle
described in Paragraph 2.2.2. of Annex 4.
The headlamp shall be considered as acceptable if ∆r does not exceed 1.5mrad upwards
and does not exceed 2.5mrad downwards.
If this value exceeds 1.5mrad but is not more than 2.0mrad upwards or exceeds 2.5mrad
but is not more than 3.0mrad downwards, the second headlamp of sample A shall be
subjected to the test after which the mean of the absolute values recorded in both samples
shall not exceed 1.5mrad upwards and shall not exceed 2.5mrad downwards.
However, if this value of 1.5mrad upwards and 2.5mrad downwards on sample A is not
complied with, the two headlamps of sample B shall be subjected to the same procedure
and the value of ∆r for each of them shall not exceed 1.5mrad upwards and shall not exceed
2.5mrad downwards."
Figure 1, shall be deleted.
