GENERAL SPECIFICATIONS 

Each  sample,  when  its  approval  is  sought  for  right-hand  traffic  only,  shall  conform  to 
the  specifications  set  forth  in  paragraphs 6.  and  7.  below;  if  however  its  approval  is 
sought for left-hand traffic, the provisions of paragraph 6. below, including the relevant 
Annexes to this Regulation, apply with the inversion of right to left and vice versa.  
Correspondingly,  the  designation  of  the  angular  positions  and  elements  is  adjusted  by 
exchanging "R" for "L" and vice versa. 

5.1.2. 

Systems  or  part(s)  thereof,  shall  be  so  made  as  to  retain  their  prescribed  photometric 
characteristics and to remain in good working order when in normal use, in spite of the 
vibrations to which they may be subjected.

Regulation No. 37 or 99; 

If  a  light  source  is  replaceable,  its  lamp  holder  shall  conform  to  the  dimensional 
characteristics given on the data sheet of IEC Publication No. 60061-2, as referred to in 
the relevant light source Regulation; 

If a light source is non-replaceable, it shall not be a part of a lighting unit that provides 
the passing beam in the neutral state. 

System(s) or part(s) thereof, designed to satisfy the requirements both of right-hand and 
of left-hand traffic may  be adapted for traffic on a  given side of the road either by an 
appropriate initial setting when fitted on the vehicle or by selective setting by the user.  
In any case, only two different and clearly distinct settings, one for right-hand and one 
for left-hand traffic, shall be possible, and the design shall preclude inadvertent shifting 
from one setting to the other or setting in an intermediate state. 

Complementary  tests  shall  be  done  according  to  the  requirements  of  Annex 4  of  this 
Regulation  to  ensure  that  in  use  there  is  no  excessive  change  in  photometric 
performance.

passing  beam,  any  mechanical,  electro-mechanical  or  other  device  incorporated  in  the 
lighting unit(s), for switching from one to the other beam shall be so constructed that: 

the  device  is  strong  enough  to  withstand  50,000  operations  without  suffering  damage 
despite the vibrations to which it may be subjected in normal use; 

either  the  passing  beam  or  the  driving  beam  shall  always  be  obtained,  without  any 
possibility  of  remaining  in  an  intermediate  or  undefined  state;  if  this  is  not  possible, 
such a state must comply with the provisions of paragraph 5.7.3. below; 

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 1.5  lx 
in the zone III b as defined in Annex 3 to this Regulation and at least 4 lx in a point of 
"segment  Emax",  by  such  means  as  e.g.  switching  off,  dimming,  aiming  downwards, 
and/or functional substitution;

Netherlands  (E4)  pursuant  to  this  Regulation  under  approval  number  19243,  meeting  the 
requirements  of  this  Regulation  in  its  original  form  (00).    The  passing  beam  is  designed  for 
right-hand traffic only.  The letters "CT"  (Figure 1) indicate that it concerns a passing beam with 
bending mode and the letters "CWR" (Figure 2) indicate that it concerns a class C passing beam and 
a class W passing beam and a driving beam. 

Number 30 indicates that the maximum luminous intensity of the driving beam is between 86 250 
and 101 250 candelas. 

Note: The approval number and additional symbols shall be placed close to the circle surrounding 
the letter "E" and either above or below that letter "E", or to the right or left of that letter.  The digits 
of the approval number shall be on the same side of that letter "E" and face in the same direction. 

The use of Roman numerals as approval numbers should be avoided so as to prevent any confusion 
with other symbols.

In  example 7a: the installation unit 1 (or 2) of the system comprises a class C passing beam with 
bending mode, a class W passing beam, a class V passing beam and a class E passing beam.  The 
score above "C" indicates that the class C passing beam is provided by two installation units on that 
side of the system. 

The installation unit 3 (or 4) is designed to provide a second part of the class C passing beam on 
that side of the system as indicated by the score above "C". 

In example 7b: the installation unit 1 (or 2) of the system is designed to provide a class C passing 
beam, a class W passing beam and a class E passing beam.  The score above "W" indicates that the 
class W passing beam is provided by two installation units on that side of the system.  The letter "T" 
to the right, following the listed symbols (and left of the approval number) indicates that each, the 
class C passing beam, the class W passing beam, the class E passing beam, and the driving beam 
are providing a bending mode. 

The  installation  unit  3  (or  4)  of  the  system  is  designed  to  provide  the  second  part  of  the  class 
W passing  beam  on  that  side  of  the  system  (as  indicated  by  the  score  above  "W"),  and  the  class 
V passing beam.

The system bearing the above approval marks meets the requirements of this Regulation (00 series 
of amendments) in respect of both a passing beam for left-hand traffic and a driving beam with a 
maximum intensity  comprised  between  86 250  and  101 250  candelas  (as  indicated  by  the  number 
30) grouped with a front direction indicator lamp of category 1a, approved in accordance with the 
01  series  of  amendments  of  Regulation  No.  6  and  a  front  position  lamp  approved  in  accordance 
with the 02 series of amendments of Regulation No. 7. 

The installation unit 1 of the system (left side) is designed to contribute to the class C passing beam 
and  the  class  E  passing  beam.    The  score  above  "C"  indicates  that  on  that  side  more  than  one 
installation unit contributes to the class C passing beam.  The letter "T" to the right following the 
listed  symbols  indicates  that  each,  the  class  C  passing  beam  and  the  class  E  passing  beam  are 
providing a bending mode. 

The installation unit 3 of the system (left side) is designed to provide the second part of the class C 
passing beam of that side (as indicated by the score above "C") and a class W passing beam. 

The  installation  unit  2  of  the  system  (right  side)  is  designed  to  contribute  to  the  class  C  passing 
beam, a class E passing beam, both with bending mode and a class W passing beam. 

Note:  In the above examples Nos. 6, 7 and 8 the different installation units of the system shall bear 
the same approval number.

1.1.1.2.  Test voltage 

(a) 

In case of replaceable filament light source(s) operated directly under vehicle voltage 
system conditions: 

The  voltage  shall  be  adjusted  so  as  to  supply  90  per  cent  of  the  maximum  wattage 
specified  in  Regulation  No.  37  for  the  filament  light  source(s)  used.    The  applied 
wattage  shall  in  all  cases  comply  with  the  corresponding  value  of  a  filament  light 
source  of  12 V  rated  voltage,  except  if  the  applicant  specifies  that  the  test  sample 
may be used at a different voltage.  In this case, the test shall be carried out with the 
filament light source whose wattage is the highest that can be used. 

In  case  of  replaceable  gas  discharge  light  source(s):  The  test  voltage  for  the 
electronic  light  source  control-gear  is  13.5 ± 0.1  volts  for  12  V  vehicle  voltage 
system, or otherwise specified in the application for approval. 

In  the  case  of  non-replaceable  light  source  operated  directly  under  vehicle  voltage 
system  conditions:  All  measurements  on  lighting  units  equipped  with  non-
replaceable  light  sources  (filament  light  sources  and/or  others)  shall  be  made 
at 6.75 V,  13.5 V  or  28.0 V  or  at  other  voltages  according  to  the  vehicle  voltage 
system as specified by the applicant respectively. 

In  the  case  of  light  sources,  replaceable  or  non-replaceable,  being  operated 
independently from vehicle supply voltage and fully controlled by the system, or, in 
the case of light sources supplied by a supply and operating device, the test voltages 
as  specified  above  shall  be  applied  to  the  input  terminals  of  that  device.    The  test 
laboratory may  require from the manufacturer the supply  and operating device or a 
special power supply needed to supply the light source(s).

2. 

TEST  FOR  CHANGE  IN  VERTICAL  POSITION  OF  THE  "CUT-OFF"  LINE  UNDER 
THE INFLUENCE OF HEAT. 

This test consists of verifying that the vertical drift of the cut-off line under the influence of 
heat does not exceed a specified value for a system or part(s) of emitting a class C (basic) 
passing beam, or each specified passing beam mode. 

If  the  test  sample  consists  of  more  than  one  lighting  unit  or  more  than  one  assembly  of 
lighting units which provide a cut-off, each of these is understood to be a test sample for 
the purpose of this test and must be tested separately. 

The  test  sample  tested  in  accordance  with  paragraph  1.  shall  be  subjected  to  the  test 
described in paragraph 2.1., without being removed from or readjusted in relation to its test 
fixture. 

If the test sample has a moving optical part, only the position closest to the average vertical 
angular  stroke  and/or  the  initial  position  according  to  the  neutral  state  is  chosen  for  this 
test. 

The test is confined to signal input conditions corresponding to a straight road, only.

samples  shall  be  taken  and  tested.    The  manufacturer  shall  take  steps  to  ensure  the 
conformity of the production concerned. 

2.1. 

Nature of tests 

Tests of conformity in this Regulation shall cover the photometric characteristics and the 
verification of the change in vertical position of the cut-off line for passing beam under the 
influence of heat. 

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. 

In any test of conformity carried out by the manufacturer, equivalent methods may be used 
with  the  consent  of  the  competent  authority  responsible  for  approval  tests.    The 
manufacturer  is  responsible  for  proving  that  the  applied  methods  are  equivalent  to  those 
laid down in this Regulation. 

2.2.3.  The application of paragraphs 2.2.1. and 2.2.2. requires regular calibration of test apparatus 

and its correlation with measurement made by a competent authority. 

2.2.4. 

In  all  cases  the  reference  methods  shall  be  those  of  this  Regulation,  particular  for  the 
purpose of administrative verification and sampling. 

2.3. 

Nature of sampling 

Samples of systems shall be selected at random from the production of a uniform batch.  A 
uniform batch means a set of systems of the same type, defined according to the production 
methods of the manufacturer. 
The  assessment  shall,  in  general,  cover  series  production  from  individual  factories.  
However,  a  manufacturer  may  group  together  records  concerning  the  same  type  from 
several  factories  provided  these  operate  under  the  same  quality  system  and  quality 
management. 

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 Emax, HV 1/, "HL" and "HR" 2/ in the case of a driving beam, 

to  points  B50L  ,  HV  if  applicable,  50V,  75R  if  applicable,  and  25LL  in  the  case  of  the 
passing beam(s) (see Figure 1 in Annex 3). 

2.5. 

Criteria governing acceptability 

The  manufacturer  is  responsible  for  carrying  out  a  statistical  study  of  the  test  results  and 
for defining, in agreement with the competent authority, criteria governing acceptability of 
his products in order to meet the specification laid down for verification of conformity of 
products in paragraph 9.1. of this Regulation. 

_____________ 
1/  When the driving beam is reciprocally incorporated with the passing beam, HV in the case of the 
driving beam shall be the same measuring point as in the case of the passing beam. 
2/    "HL"  and  "HR":  points  on  "H-H"  located  at  2.6  deg  to  the  left  and  to  the  right  of  point  HV 
respectively.

The  test  mixture  shall  be  composed  of  61.5  per  cent  n-heptane,  12.5 per  cent  toluene, 
7.5 per  cent  ethyl  tetrachloride,  12.5 per  cent  trichloroethylene  and  6 per  cent  xylene 
(volume per cent). 

2.2.2.2.  Application of the test mixture 

Soak a piece of cotton cloth (as per ISO 105) until saturation with the mixture defined in 
paragraph 2.2.2.1. above and, within 10 seconds, apply it for 10 minutes to the outer face 
2
of the sample at a pressure of 50 N/cm
, corresponding to an effort of 100 N applied on a 
test surface of 14 x 14 mm. 

During this 10-minute period, the cloth pad shall be soaked again with the mixture so that 
the composition of the liquid applied is continuously identical with that of the test mixture 
prescribed. 

During the period of application, it is permissible to compensate the pressure applied to the 
sample in order to prevent it from causing cracks. 

2.2.2.3.  Cleaning 

At the end of the application of the test mixture, the samples shall be dried in the open air 
and then washed with the solution described in paragraph 2.3. (Resistance to detergents) at

A  convergent  achromatic  lens  L2,  corrected  for  spherical  aberrations  links  the  diaphragm  Dτ 
with  the  receiver  R;  the  diameter  of  the  lens  L2  shall  be  such  that  it  does  not  diaphragm  the 
light diffused by the sample in a cone with a half top angle of β/2 = 14 deg.  

An annular diaphragm DD, with angles αο/2 = 1 deg and αmax/2 = 12 deg is placed in an image 
focal plane of the lens L2. 

The  non-transparent  central  part  of  the  diaphragm  is  necessary  in  order  to  eliminate  the  light 
arriving  directly  from  the  light  source.    It  shall  be  possible  to  remove  the  central  part  of  the 
diaphragm from the light beam in such a manner that it returns exactly to its original position. 

The distance L2 Dτ and the focal length F2 of the lens L2 shall be so chosen that the image of 
Dτ completely covers the receiver R. 

For L2 it is recommended to use a focal distance of about 80 mm. 

  When  the  initial  incident  flux  is  referred  to  1  the  absolute  precision  of  each  reading  shall  be 

better than 0.001.

diameter  on  the  surface  exposed  to  deterioration,  at  a  distance  of  380 mm ± 10 mm  from 
the nozzle. 

1.2. 

Test mixture 

The test mixture shall be composed of: 

Silica sand of hardness 7 on the Mohr scale, with a grain size between 0 and 0.2 mm and 
an almost normal distribution, with an angular factor of 1.8 to 2; 

Water of hardness not exceeding 205 g/m
of water. 

3
 for a mixture comprising 25 g of sand per litre 

2. 

Test 

The  outer  surface  of  the  lamp  lenses  shall  be  subjected  once  or  more  than  once  to  the 
action  of  the  sand  jet  produced  as  described  above.    The  jet  shall  be  sprayed  almost 
perpendicular to the surface to be tested. 

The deterioration shall be checked by means of one or more samples of glass placed as a 
reference near the lenses to be tested.  The mixture shall be sprayed until the variation in 
the  diffusion  of  light  on  the  sample  or  samples  measured  by  the  method  described  in 
Appendix 2, is such that:  ∆d = (T5 - T4)/ T2 = 0.0250 ± 0.0025.

ADHESIVE TAPE ADHERENCE TEST 

1.  PURPOSE 

This method allows to determine under standard conditions the linear force of adhesion of an 
adhesive tape to a glass plate. 

2.  PRINCIPLE 
  Measurement of the force necessary to unstick an adhesive tape from a glass plate at an angle 

of 90 deg. 

3.  SPECIFIED ATMOSPHERIC CONDITIONS 
ο
ο
The ambient conditions shall be at 23 
C and 65 ± 15 per cent relative humidity. 
C ± 5 

4.  TEST PIECES 

Before  the  test,  the  sample  roll  of  adhesive  tape  shall  be  conditioned  for  24  hours  in  the 
specified atmosphere (see paragraph 3. above). 
Five  test  pieces  each  400  mm  long  shall  be  tested  from  each  roll.    These  test  pieces  shall  be 
taken from the roll after the first three turns were discarded. 

5.  PROCEDURE 

The test shall be under the ambient conditions specified in paragraph 3. 
Take  the  five  test  pieces  while  unrolling  the  tape  radially  at  a  speed  of  approximately 
300 mm/s, then apply them within 15 seconds in the following manner: 
Apply the tape to the glass plate progressively with a slight length- wise rubbing movement of 
the finger, without excessive pressure, in such a manner as to leave no air bubble between the 
tape and the glass plate. 
Leave the assembly in the specified atmospheric conditions for 10 minutes. 
Unstick about 25 mm of the test piece from the plate in a plane perpendicular to the axis of the 
test piece. 
Fix the plate and fold back the free end of the tape at 90 deg.  Apply  force in such a manner 
that  the  separation  line  between  the  tape  and  the  plate  is  perpendicular  to  this  force  and 
perpendicular to the plate. 
Pull to unstick at a speed of 300 mm/s ± 30 mm/s and record the force required. 

6.  RESULTS 

The five values obtained shall be arranged in order and the median value taken as a result of the 
measurement.  This value shall be expressed in Newton per centimetre of width of the tape.

CHANGE  OF  THE  VERTICAL  POSITION  OF  THE  CUT-OFF  LINE  FOR  PASSING 
BEAM 

With  respect  to  the  verification  of  the  change  in  vertical  position  of  the  cut-off  line  for 
passing beam under the influence of heat, the following procedure shall be applied: 

One of the systems of sample A after sampling procedure in Figure 1 of this annex 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 system shall be considered as acceptable if ∆r does not exceed 1.5 mrad. 

If this value exceeds 1.5 mrad but is not more than 2.0 mrad, the second system of sample 
A  shall  be  subjected  to  the  test  after  which  the  mean  of  the  absolute  values  recorded  on 
both samples shall not exceed 1.5 mrad. 

However, if this value of 1.5 mrad on sample A is not complied with, the two systems of 
sample  B  shall  be  subjected  to  the  same  procedure  and  the  value  of ∆r  for  each  of  them 
shall not exceed 1.5 mrad.

a horizontal ("elevation") axis fixed to the ground and a second, moveable ("rotation") axis 
perpendicular to the fixed horizontal axis.

Any equivalent photometric method is acceptable, if the accordingly applicable correlation 
is observed. 

Any offset of the centre of reference of each lighting unit, with respect to the goniometer 
rotation  axes,  should  be  avoided.    This  applies  especially  to  the  vertical  direction  and  to 
lighting units producing a "cut-off". 

An  aiming  screen  shall  be  used  and  may  be  located  at  a  shorter  distance  than  that  of  the 
photoreceptor.

2.2. 

In the case of a replaceable gas-discharge light source: 

The  system  or  parts  thereof  using  a  replaceable  gas-discharge  light  source  shall  comply 
with  the  photometric  requirements  set  out  in  the  relevant  paragraphs  of  this  Regulation 
with  at  least  one  standard  (étalon)  light  source,  which  has  been  aged  during  at 
least 15 cycles, as specified in Regulation No. 99.  The luminous flux of this gas-discharge 
light source may differ from the objective luminous flux specified in Regulation No. 99. 

In this case, the measured photometric values shall be corrected accordingly.  They shall be 
multiplied by a factor of 0.7 prior to the check for compliance. 

2.3. 

In  the  case  of  a  non-replaceable  light  source  operating  directly  under  vehicle  voltage 
system conditions: 

All  measurements  on  lamps  equipped  with  non-replaceable  light  sources  (filament  lamps 
and other) shall be made at 6.75 V, 13.5 V or 28.0  V, or at a voltage as specified by the

applicant  with  respect  to  any  other  vehicle  voltage  system.    The  measured  photometric 
values shall be multiplied by a factor of 0.7 prior to the check for compliance. 

2.4. 

In  the  case  of  a  light  source,  replaceable  or  non-replaceable,  which  is  operated 
independently  from  vehicle  supply  voltage  and  fully  controlled  by  the  system,  or  in  the 
case of a light source supplied by a special power supply, the test voltage as specified in 
paragraph 2.3. above shall be applied to the input terminals of that system/power supply.  
The test laboratory may require from the manufacturer this special power supply needed to 
supply the light sources. 

The measured photometric values shall be multiplied by a factor of 0.7 prior to the check 
for  compliance,  except  if  this  correction  factor  is  already  applied  according  to  the 
provisions of paragraph 2.2. above. 

3. 

MEASUREMENT CONDITIONS WITH RESPECT TO BENDING MODES 

3.1. 

In the case of a system or part(s) thereof, which provide a bending mode, the requirements 
of paragraphs 6.2. (passing beam), and/or 6.3. (driving beam) of this Regulation apply for 
all states, corresponding to the turn radius of the vehicle.  For verification with respect to 
the passing beam and the driving beam the following procedure shall be used: 

3.1.1.  The  system  shall  be  tested  in  the  neutral  state  (central/straight),  and,  in  addition  in  the 
state(s) corresponding to the smallest turn radius of the vehicle in both directions using the 
signal generator, if applicable. 

3.1.1.1.  Compliance  with  the  requirements  of  paragraphs  6.2.6.2.,  6.2.6.3.  and  6.2.6.5.1.  of  this 
Regulation  shall  be  checked  for  both  category  1  and  category  2  bending  modes  without 
additional horizontal re-aim. 

3.1.1.2.  Compliance  with  the  requirements  of  paragraphs  6.2.6.1.  and  6.3.  of  this  Regulation, 

whichever applies, shall be checked: 
- 
- 

in case of a category 2 bending mode: without additional horizontal re-aim; 
in case of a  category 1 or a driving beam bending mode: after having horizontally re-
aimed  the  relevant  installation  unit  (by  means  of  the  goniometer  for  example)  in  the 
corresponding opposite direction. 

3.1.2.  When  testing  a  category  1  or  category  2  bending  mode,  for  a  turn  radius  of  the  vehicle 
other  than  specified  in  paragraph  3.1.1.  above:  it  shall  be  observed  whether  the  light 
distribution  is  substantially  uniform  and  no  undue  glare  occurs.    If  this  can  not  be 
confirmed the compliance with the requirements laid down in Table 1 of Annex 3 to this 
Regulation shall be checked.
