ANNEX 8
DESCRIPTION OF DUMMIES
1. GENERAL
1.1. The dummies prescribed in this Regulation are described in this annex, in technical drawings
held by Humanetics Innovative Solutions Inc. and in the user manuals delivered with the
dummies.
1.2. Alternative dummies may be used provided that:
1.2.1. Their equivalence can be demonstrated to the satisfaction of the Type Approval Authority, and
1.2.2. Their use is recorded in the test report, and in the communication form described in Annex 1 to
this Regulation.
2. DESCRIPTION OF THE DUMMIES
2.1. The dimensions and masses of the Q0, Q1, Q1.5, Q3, Q6 and Q10 dummies described below
are based on the anthropometry of 50 percentile children aged 0, 1, 1.5, 3, 6 and 10.5 years
respectively.
2.2. The dummies consist of a metal and plastic skeleton covered with plastic skinned foam parts to
complete body components.
3. CONSTRUCTION
3.1. Head
3.2. Neck
3.3. Thorax
The head is largely made from synthetics. The head cavity is large enough to allow use of
several instruments, including linear accelerometers and angular velocity sensors.
The neck is flexible and allows shear and bending in all directions. The segmented design
allows a realistic rotational behaviour. The neck is equipped with low stretch neck-cord in order
to prevent excessive elongation. The neck-cord is also designed to act as a safety cord in case
of rubber failure. A six channel load cell can be mounted at the neck-head and neck-torso
interface. The Q0, Q1 and Q1.5 cannot accommodate the load cell between neck and torso.
The thorax of the child is represented by a single rib-cage. The deformation can be measured
with a string potentiometer in Q1 and Q1.5 and an IR-TRACC sensors in Q3, Q6 and Q10. The
shoulders are connected with a flexible joint to the thorax, allowing deformation forwards.
3.4. Accelerometers can be mounted on the spine to measure linear accelerations. The Q0 thorax
has a simplified layout with an integral foam part for the complete torso.

"Universal", "Semi Universal" and "Restricted", in relation to the dynamic tests according to
Paragraph 1.6. above.
In accordance with the relevant authorities, the holder of an approval will supervise the control
of conformity following the method of batch control (Paragraph 2.2.1. below) or following the
method of continuous control (Paragraph 2.2.2. below).
2.2.1. Batch Control for the Child Restraint Systems
2.2.1.1. The holder of an approval shall divide the Child Restraint Systems into batches which are as
uniform as possible in regard to raw material or intermediate products involved in their
manufacture (different colour of shell, different manufacture of harness) and in regard to
production conditions. The numbers in a batch shall not exceed 5,000 units.
In agreement with the relevant authorities the tests can be carried out by the Technical Service
or under the responsibility of the holder of an approval.
2.2.1.2. A sample shall be taken in each batch in accordance with the provisions of Paragraph 2.2.1.4.
below from a minimum of 20% of the batch quantity, which has to be produced of the actual
batch.
2.2.1.3. The characteristics of the Child Restraint Systems and the number of dynamic tests to be
conducted are given in Paragraph 2.2.1.4. below

2.2.2. Continuous Control
2.2.2.1. The holder of an approval shall be obliged to carry out continuous quality control of his
manufacturing process on a statistical basis and by sampling. In agreement with the relevant
authorities, the tests can be carried out by the Technical Service or under the responsibility of
the holder of an approval which is responsible for the traceability of the product.
2.2.2.2. The samples shall be taken in accordance with the provisions of Paragraph 2.2.2.4. below.
2.2.2.3. The characteristic of the Child Restraint Systems is taken at random and the tests to be carried
out are described in Paragraph 2.2.2.4. below.
2.2.2.4. Control shall meet the following requirements:
Child Restraint Systems taken
0.02% means one Child Restraint System taken from every 5,000
manufactured
0.05% means one Child Restraint System taken from every 2,000
manufactured
Degree of control rigour
Normal
Strengthened
This dual sampling plan functions as follows:
If the Child Restraint System is considered to conform, the production conforms.
If the Child Restraint System does not meet the requirements, a second Child Restraint System
shall be taken.
If the second Child Restraint System meets the requirements, the production conforms.
If both (the first and the second) Child Restraint Systems do not meet the requirements, the
production does not conform and Child Restraint Systems that are likely to present the same
failure shall be withdrawn and necessary steps shall be taken to re-establish the conformity of
the production.
Strengthened control will replace normal control if, out of 10,000 Child Restraint Systems
manufactured consecutively, the production has to be withdrawn twice.
Normal control is resumed if 10,000 Child Restraint Systems manufactured consecutively are
considered to conform.
If production subjected to the strengthened control has been withdrawn on two consecutive
occasions, the provisions of Paragraph 13. of this Regulation are applied.
2.2.2.5. The continuous control of Child Restraint Systems is undertaken starting after the production
qualification.
2.2.2.6. The test results described in Paragraph 2.2.2.4. above shall not exceed L, where L is the limit
value prescribed for each approval test.

ANNEX 14
METHOD OF DEFINING HEAD IMPACT AREA OF DEVICES WITH BACKRESTS AND
FOR REARWARD-FACING DEVICES DEFINING THE MINIMUM SIZE OF SIDE WINGS
1. Place the device on the test bench described in Annex 6. Reclinable devices shall be set in the
most upright position. Place the smallest manikin in the device in accordance with the
manufacturer's instructions. Mark a point "A" on the backrest on the same horizontal level as
the shoulder of the smallest manikin at a point 2cm inside the outer edge of the arm. All internal
surfaces above the horizontal plane passing through point A, shall be tested in accordance with
Annex 17. This area shall include the backrest and side wings, including the inner edges
(zone of radius) of the side wings. In the case of carrycot devices where a symmetrical
installation of the dummy is not possible according to the device and manufacturer instructions,
the area complying with Annex 17 shall be all internal surfaces above a point "A", as previously
defined, in the head direction, when measured with this dummy in the carrycot in its worst
position consistent with the manufacturer instructions and the carrycot positioned on the test
bench.
If a symmetrical installation of the dummy in the carry-cot may be possible, the whole inner
surfaces shall be covered with material complying with Annex 13.
2. For rearward-facing devices there shall be side wings with a depth of minimum 90mm
measured from the median of the surface of the backrest. These side wings shall start at the
horizontal plane passing through point "A" and continue to the top of the Child Restraint
System seat-back. Starting from a point 90mm below the top of the Child Restraint System
seat-back, the depth of the side wing may be gradually reduced.

1. DEFINITIONS
ANNEX 23
FLAMMABILITY OF MATERIALS INTENDED TO BE USED IN BUILT-IN
CHILD RESTRAINT SYSTEMS
ʺOccupant compartment air spaceʺ means the space within the occupant compartment that
normally contains refreshable air.
2. MATERIAL SELECTION (see Figure 1 below)
2.1. Any portion of a single or composite material which is within 13mm of the occupant
compartment air space shall meet the requirements in Paragraph 6.1.6.
2.1.1. Any material that does not adhere to other material(s) at every point of contact shall meet the
requirements of Paragraph 6.1.6.when tested separately.
2.1.2. Any material that adheres to other materials at every point of contact shall meet the
requirements of Paragraph 6.1.6. when tested as a composite with the other material(s).
Material A has a non-adhering interface with Material B and is tested separately.
Part of material B is within 13mm of the occupant compartment air space, and Materials B
and C adhere at every point of contact; therefore, B and C are tested as a composite.
The cut is in Material C as shown in Figure 1, to make a specimen 13mm thick.
Figure 1

4.3. Material with a napped or tufted surface is placed on a flat surface and combed twice against
the nap with a comb having seven to eight smooth, rounded teeth per 25mm.
5. TEST
5.1. Mount the specimen so that both sides and one end are held by the U-shaped frame, and
specimen is not more than 51mm, so that the sides of the specimen cannot be held in the
U-shaped frame, place the specimen in position on wire supports as described in 2.3, with one
end held by the closed end of the U-shaped frame.
5.2. Place the mounted specimen in a horizontal position, in the centre of the cabinet.
5.3. With the flame adjusted according to 2.4, position the bunsen burner and specimen so that the
centre of the burner tip is 19mm below the centre of the bottom edge of the open end of the
specimen.
5.4. Expose the specimen to the flame for 15s.
5.5. Begin timing (without reference to the period of application of the burner flame) when the flame
from the burning specimen reaches a Point 38mm from the open end of the specimen.
5.6. Measure the time that it takes the flame to progress to a Point 38mm from the clamped end of
the specimen. If the flame does not reach the specified end point, time its progress to the point
where flaming stops.
5.7. Calculate the burn rate from the formula:
B = 60 × (D/T)
Where:
B = Burn rate in millimetres per minute
D = Length the flame travels in millimetres, and
T = Time in seconds for the flame to travel D millimetres.
