Sixtieth session
Geneva, 1 - 3 October 2008
Item 5(i) of the provisional agenda
COLLECTIVE AMENDMENTS
Regulations Nos. 98, 112 and 123
Proposal for a draft corrigendum to Regulations Nos. 98, 112 and 123
Submitted by the expert from the Working Party "Brussels 1952" /
The text reproduced below was prepared by the expert from the Working
Party "Brussels 1952" (GTB) in order to harmonize and editorially
update Regulations Nos. 98, 112 and 123 with regard to the provisions
for traffic change mode. They are intended to enable the practical
application of the Regulations and do not imply any technical
modification. The modifications to the current text of Regulation No.
98, including Supplement 10 to the original version, Regulation No.
112 including Supplement 9 to the original version and Regulation No.
123 including Supplement 2 to the original version, are marked in bold
or strikethrough characters.
A. PROPOSAL
REGULATION No. 98 (Headlamps with gas-discharge light sources) (The
following text is based upon Supplement 10 to the Regulation)
Paragraphs 5.4. to 5.4.2.2., amend to read:
"5.4. Illumination configuration for different traffic conditions
5.4.1. In the case of headlamps designed to meet the requirements of
traffic moving on one side of the road (either right or left) only,
appropriate measures shall be taken to prevent discomfort to users in
a country where traffic moves on the side of the road opposite to that
of the country for which the headlamp was designed. Such measures may
be:
(a) occulting a part of the outer headlamp lens area;
(b) downward adjustment movement of the beam. In this case, the
adjustment movement shall be at least 0.3 degree vertically.
Horizontal adjustment movement is allowed;
(c) any other measure to remove the asymmetrical part of the beam.
5.4.2. Following the application of this (these) measure(s) the
following requirements regarding illumination shall be met: with the
adjustment left unchanged compared to that for the original traffic
direction:
(a) points 50 L (for right-hand traffic) or 50 R (for left-hand
traffic) at least five lux;
(b) point B 50 R (for right-hand traffic) or B 50 L (for left-hand
traffic) not more than one lux."
5.4.2.1. Passing beam designed for right-hand traffic and adapted to
left-hand traffic:
at 0.86D-1.72L at least 5 lux
at 0.57U-3.43R not more than 1.4 lux
5.4.2.2. Passing beam designed for left-hand traffic and adapted to
right-hand traffic:
at 0.86D-1.72R at least 5 lux
at 0.57U-3.43L not more than 1.4 lux "
REGULATION No. 112 (Headlamps emitting an asymmetrical passing beam)
(The following text is based upon Supplement 9 to the Regulation)
Paragraphs 5.8. to 5.8.2.2., amend to read:
"5.8. Illumination configuration for different traffic conditions
5.8.1. In the case of headlamps designed to meet the requirements of
traffic moving on one side of the road (either right or left) only,
appropriate measures shall be taken to prevent discomfort to users in
a country where traffic moves on the side of the road opposite to that
of the country for which the headlamp was designed. Such measures may
be:
(a) occulting a part of the outer headlamp lens area;
(b) downward adjustment movement of the beam. In this case, the
adjustment movement shall be at least 0.3 degree vertically.
Horizontal adjustment movement is allowed;
(c) any other measure to remove the asymmetrical part of the beam.
5.8.2. Following the application of this (these) measure(s) the
following requirements regarding illumination shall be met: with the
adjustment left unchanged compared to that for the original traffic
direction:
(a) points 50 L (for right-hand traffic) or 50 R (for left-hand
traffic) at least three lux;
(b) point B 50 R (for right-hand traffic) or B 50 L (for left-hand
traffic) not more than one lux.
5.8.2.1. Passing beam designed for right-hand traffic and adapted to
left-hand traffic:
at 0.86D-1.72L at least 3 lux
at 0.57U-3.43R not more than 1.0 lux
5.8.2.2. Passing beam designed for left-hand traffic and adapted to
right-hand traffic:
at 0.86D-1.72R at least 3 lux
at 0.57U-3.43L not more than 1.0 lux "
REGULATION No. 123 (Adaptive front-lighting systems (AFS)) (The
following text is based upon Supplement 2 to the Regulation)
Paragraphs 5.8.2. and 5.8.2.1., amend to read:
"5.8.2. provide means to achieve a traffic-change function, meeting
the values shown in the following table when tested according to
paragraph 6.2. below with the adjustment left unchanged compared to
that for the original traffic direction;
5.8.2.1. Passing beam designed for right-hand traffic and adapted to
left-hand traffic:
at 0.86D-1.72L at least 3 lux
at 0.57U-3.43R not more than 1.0 lux"
Insert a new paragraph 5.8.2.2., to read:
"5.8.2.2. Passing beam designed for left-hand traffic and adapted to
right-hand traffic:
at 0.86D-1.72R at least 3 lux
at 0.57U-3.43L not more than 1.0 lux "
Paragraph 5.8.2.1. (former), renumber as paragraph 5.8.2.3.
B. JUSTIFICATION
Currently, the requirements concerning traffic change mode vary
between Regulations Nos. 98, 112 and 123. This situation causes
problems in case the same passing beam lighting unit has to be
type-approved according to Regulation No. 98 or 112 and as part of
Adaptive Front-lighting Systems (AFS) according to Regulation No. 123.
In order to align the requirements, it is proposed that the provisions
adopted in Regulations Nos. 98 and 112 are used as a basis since they
represent the latest recommendations of GTB experts and supersede
those in Regulation No. 123.
