2.4. When production is found to be non-conforming according to Paragraphs 2.2.1.4., 2.2.2.4. or
2.3.2. above, the holder of the approval or his duly accredited representative shall:
2.4.1. Notify the Type Approval Authority which has granted type approval indicating what steps have
been taken to re-establish the conformity of production.
2.5. The manufacturer shall advise the Type Approval Authority on a quarterly basis, the volume of
products produced against each approval number, providing a means of identifying which
products correspond to that approval number.

3. PROCEDURE
3.1. The child restraint shall be placed in the region of impact on a rigid flat surface, whose
minimum dimensions are 500 x 500mm, so that the direction of impact is perpendicular to the
inner surface of the Child Restraint System in the area of impact.
3.2. Raise the headform to a height of 100 -0/+5mm from the respective upper surfaces of the
assembled Child Restraint System to the lowest point on the headform, and allow it to fall.
Record the acceleration experienced by the headform during impact.

DESCRIPTION OF CONDITIONING OF ADJUSTERS MOUNTED
DIRECTLY ON CHILD RESTRAINT SYSTEMS
1. METHOD
Figure 1
1.1. With the webbing set at the reference position described in Paragraph 7.2.6., withdraw at least
50mm of webbing from the integral harness by pulling on the free end of the webbing.
1.2. Attach the adjusted part of the integral harness to the pulling device A.
1.3. Activate the adjuster and pull at least 150mm of webbing into the integral harness. This
represents half of one cycle and puts pulling device A to the maximum webbing extraction
position.
1.4. Connect free end of webbing to pulling device B.
2. The cycle is:
2.1. Pull B at least 150mm whilst A exerts no tension on the integral harness.
2.2. Activate the adjusters and pull A whilst B exerts no tension on the free end of the webbing.
2.3. At the end of stroke, de-activate the adjuster.
2.4. Repeat cycle as specified in Paragraph 6.7.2.7. of this Regulation.

ANNEX 17
DETERMINATION OF PERFORMANCE CRITERIA
1. Head Performance Criterion (HPC)
1.1. This criterion is considered to be satisfied when, during the test, there is no contact between
the head and any vehicle component.
1.2. If that is not the case, a calculation of the value of HPC is made, on the basis of the
acceleration (a), by the following expression:
In which:

1
HPC =
⎢t
− t ∫

( t − t ) ⎢ adt




1.2.1. The term "a" is the resultant acceleration is measured in units of gravity, g (1g = 9.81m/s );
1.2.2. If the beginning of the head contact can be determined satisfactorily, t and t are the two time
instants, expressed in seconds, defining an interval between the beginning of the head contact
and the end of the recording for which the value of HPC is maximum;
1.2.3. If the beginning of the head contact cannot be determined, t and t are the two time instants,
expressed in seconds, defining a time interval between the beginning and the end of the
recording for which the value of HPC is maximum;
1.2.4. Values of HPC for which the time interval (t – t ) is greater than 36ms are ignored for the
purposes of calculating the maximum value.
1.3. The value of the resultant head acceleration during forward impact which is exceeded for 3ms
cumulatively is calculated from the resultant head acceleration.

When measured under a contact force of 50N with the device described in Figure 2 of this Annex the
following tolerances will be applied to the dimensions:
Minimum Sitting height:
From 40 to 87cm B –5 Percentile
From 87cm and up B –10 Percentile,
Minimum shoulder breadth: C -0 +2cm
Minimum hip breadth: D -0 +2cm
Minimum shoulder height (5 Percentile): E1 –2 +0cm
Maximum shoulder height (95 Percentile): E2 –0 +2cm
