6. GENERAL SPECIFICATIONS
6.1. Positioning and Securing on the Vehicle
6.1.1. Enhanced child restraint systems in the i-Size category are primarily designed for use
in i-Size seating positions, when the enhanced child restraint systems are fitted in
conformity with the vehicle manufacturer's instructions.
Enhanced child restraint systems in the specific vehicle ISOFIX category are for use
in all ISOFIX positions and also in the luggage area, if the restraints are fitted in
conformity with the vehicle manufacturer's instructions.
6.1.2. According to the category in which it belongs to, see Table 1, the integral enhanced
child restraint system shall be secured to the vehicle structure or to the vehicle seat
structure:
6.1.2.1. For i-Size category, this shall be by means of two ISOFIX attachments with the
addition of an anti-rotation device for both forward and rearward-facing enhanced
child restraint systems;

6.2. Configuration of the Enhanced Child Restraint System
6.2.1. The configuration of the enhanced child restraint system shall be such that:
6.2.1.1. The restraint of the child shall give the required protection in any position specified for
the enhanced child restraint system;
For "Special Needs Restraints" the primary means of restraint shall give the required
protection in any intended position of the enhanced child restraint system without the
use of the additional restraining devices which may be present;
6.2.1.2. The enhanced child restraint system shall be such that the child may be easily and
readily restrained or removed. In the case of an enhanced child restraint system in
which the child is restrained by means of a harness belt or a Y-shaped belt without a
retractor each shoulder restraint and lap strap shall be capable of movement relative
to each other during the procedure prescribed in Paragraph 6.7.1.4. below; in these
cases the enhanced child restraint system belt assembly may be designed with two or
more connecting parts.
For special needs restraints it is recognized that the additional restraining devices will
restrict the speed by which a child can be restrained and removed. However, the
additional devices shall be designed to release quickly so far as possible;
6.2.1.3. If it is possible to change the inclination of the enhanced child restraint system, this
change in inclination shall not require manual readjustment of any other part of the
enhanced child restraint system. A deliberate hand-action shall be necessary in order
to change the inclination of the enhanced child restraint system;
6.2.1.4. To prevent submarining, either by impact or through restlessness, a crotch strap shall
be required on all integral forward-facing restraints incorporating an integral harness
belt system.
6.2.1.5. All restraint devices utilizing a lap strap shall positively guide lap strap to ensure that
the loads transmitted by the lap strap are transmitted through the pelvis. The
assembly shall not subject weak parts of the child’s body (abdomen, crotch, etc.) to
excessive stresses.
Moreover, the design shall be such that compression loads shall not be imposed on
the crown of the child’s head in the event of a collision;
6.2.1.6. All straps of the restraint shall be so placed that they cannot cause discomfort to the
wearer in normal use or assume a dangerous configuration. Y-shaped belts are not
permitted on forward facing enhanced child restraint systems and may only be used
in dedicated rearward facing and or lateral facing enhanced child restraint systems
(carrycots). The distance between the shoulder-straps in the vicinity of the neck
should be at least the width of the neck of the appropriate dummy.
6.2.1.7. With the crotch strap attached and in its longest position if adjustable, it shall not be
possible to adjust the lap strap to lie above the pelvis of both the smallest and largest
dummy within the within the size range covered by the approval. For all
forward-facing restraints, it shall not be possible to adjust the lap strap to lie above
the pelvis of both the smallest and largest dummy within the size range covered by
the approval.

6.3.1.2. The flammability of Enhanced Child Restraint Systems submitted for approval shall
be assessed by one of the following methods:
Method 1 is applicable only to non-built-in Enhanced Child Restraint Systems and
Method 2 is applicable only to vehicle specific built-in Enhanced Child Restraint
Systems.
Method 1
The Enhanced Child Restraint System manufacturer shall declare in writing that the
flammability of materials used to manufacture the Child Restraint System is in
conformity with the method of Section 5.4 of EN 71-2:2011+A1:2014 with a maximum
rate of spread of flame of 30mm/s. Tests confirming the validity of the declaration may
be carried out at the discretion of the Technical Service. Where fabrics are assembled
together, these shall be tested as a composite.
"Composite material" means a material composed of several layers of similar or
different materials intimately held together at their surfaces by cementing, bonding,
cladding, welding, etc. In such a case, the material shall be tested as a composite.
When different materials are connected together intermittently, such materials shall
not be considered as composite materials and therefore tested separately.
Tests confirming the validity of the declaration may be carried out at the discretion of
the Technical Service.
Method 2
The applicant shall declare in writing that when testing materials in accordance with
Annex 23 of this Regulation, the materials used shall not burn, nor transmit a flame
front across its surface, at a rate of more than 100mm/min. Each material used in an
enhanced child restraint system shall conform to these requirements. However, the
requirement concerning transmission of a flame front shall not apply to a surface
created by cutting a test specimen for purposes of testing pursuant to Annex 23.
The requirements shall be met in both the "in-use" and in the "stowed" positions of
the built-in Enhanced Child Restraint System.
If a material stops burning before it has burned for 60s from the start of timing, and
has not burned more than 51mm from the point where the timing was started, it shall
be considered to meet the burn-rate requirement specified above.
Tests confirming the validity of the declaration may be carried out at the discretion of
the Technical Service.

6.6.4.4.1.2. Rearward-facing enhanced child restraint systems and carrycots:
6.6.4.4.1.2.1. Head excursion: no part of the head of the dummy shall pass beyond the planes FD,
FG and DE, as shown in Figure 2 below. This shall be judged up to 300ms or the
moment that the dummy has come to a definitive standstill whatever occurs first.
In the case there is a contact of such an enhanced child restraint system with the
100mm diameter bar and all injury assessment and dummy’s head displacement
criteria are met, there shall be one further dynamic test (front impact) with the
heaviest dummy intended for the given range of size indication and without the
100mm diameter bar; the requirements for this test are that all criteria other than
forward displacement shall be met.
Where a test is conducted in accordance with Paragraph 6.6.4.1.6.2. above, only the
second configuration without 100mm diameter bar will be considered.

2.3. For specific vehicle ECRS devices according to Paragraph 2.1.2.4.1. above, the enhanced
child restraint system manufacturer may choose Conformity of Production procedures
according to either Paragraph 2.2. above, on a test bench, or Paragraphs 2.3.1. and 2.3.2.
below, in a vehicle body shell.
2.3.1. For specific vehicle ECRS devices, the following test frequencies shall apply once every eight
weeks:
At each test all requirements according to Paragraphs 6.6.4. and 6.7.1.7.1. of this Regulation
shall be fulfilled. If all tests during one year show satisfactory results, the manufacturer may,
after agreement with the Type Approval Authority, reduce the frequencies as follows: once
every 16 weeks.
However, a minimum frequency of one test per year shall be permitted where annual
production is 1,000 enhanced child restraint systems or less.
2.3.2. Where a test sample fails a particular test to which it has been subjected, a further test to the
same requirement shall be carried out on at least three other samples. In the case of dynamic
tests if one of the latter fails, the production is considered to be non-conforming and the
frequency shall be raised to the higher one if the lower one was used according to
Paragraph 2.3. above and necessary steps shall be taken to re-establish the conformity of the
production.
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 enhanced child restraint system 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 enhanced 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 enhanced child restraint system to the lowest point on the headform, and allow it to
fall. Record the acceleration experienced by the headform during impact.

DIRECTLY ON ENHANCED CHILD RESTRAINT SYSTEM
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 15ms 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.

All lateral dimensions are measured under a contact force of 50N with the device described in Figure 2 of
this Annex and the following tolerances applied:
Minimum sitting height:
– Up to 87cm B – 5%
– From stature from 87cm and up to 150cm B – 10%

ANNEX 22
INFANT CARRIER MODULE
1. DEFINITION
"Infant carrier module" means a module that is part of an integral enhanced enhanced child
restraint system restraining a child up to 15 months old and up to 13kg and which can be used
as a stand-alone enhanced child restraint system. It is designed to be removed from the vehicle
with the child inside and without opening any harness and to carry it outside of the vehicle.
2. PROVISIONS APPLIED TO THE INFANT CARRIER MODULE
2.1. Belt routing shall comply with Paragraphs 4.3. and 6.1.9. of Regulation No. 44.
2.2. Frontal impact test shall comply with Paragraph 7.1.4. of Regulation No. 44.
2.3. Rear impact test shall comply with Paragraph 7.1.4. of Regulation No. 44.
2.4. Overturning test shall comply with Paragraph 7.1.3. of Regulation No. 44.
2.5. For infant carrier module the following label shall be clearly visible on the exterior of the
packing:
Notice
This is an Enhanced Infant Carrier Module to be used in combination with i-Size product
approved according to Regulation No. 129, for use in, "i-Size compatible" vehicle seating
positions as indicated by vehicle manufacturers in the vehicle user’s manual. This module
could also be used as a stand-alone infant carrier according to the instructions of the Enhanced
Child Restraint System manufacturer.
If in doubt, consult either the manufacturer or the retailer of the Enhanced Child Restraint
System.

3. TEST PROCEDURE
3.1. The test is conducted in a metal cabinet for protecting the test specimens from drafts. The
interior of the cabinet is 381mm long, 203mm deep, and 356mm high. It has a glass
observation window in the front, a closable opening to permit insertion of the specimen holder,
and a hole to accommodate tubing for a gas burner. For ventilation, it has a 13mm clearance
space around the top of the cabinet, ten holes in the base of the cabinet, each hole 19mm in
diameter and legs to elevate the bottom of the cabinet by 10mm, all located as shown in
Figure 2.
3.2. Prior to testing, each specimen is conditioned for 24h at a temperature of 21°C, and a relative
humidity of 50%, and the test is conducted under those ambient conditions.
3.3. The test specimen is inserted between two matching U-shaped frames of metal stock 25mm
wide and 10mm high.
The interior dimensions of the U-shaped frames are 51mm wide by 330mm long.
A specimen that softens and bends at the flaming end so as to cause erratic burning is kept
horizontal by supports consisting of thin, heat-resistant wires, spanning the width of the
U-shaped frame under the specimen at 25mm intervals.
A device that may be used for supporting this type of material is an additional U-shaped frame,
wider than the U-shaped frame containing the specimen, spanned by 10mil wires of
heat-resistant composition at 25mm intervals, inserted over the bottom U-shaped frame.
3.4. A bunsen burner with a tube of 10mm inside diameter is used.
The gas adjusting valve is set to provide a flame, with the tube vertical, of 38mm in height. The
air inlet to the burner is closed.
3.5. The gas supplied to the burner has a flame temperature equivalent to that of natural gas.
4. PREPARATION OF SPECIMENS
4.1. Each specimen of material to be tested shall be a rectangle 102mm wide by 356mm long,
wherever possible.
The thickness of the specimen is that of the single or composite material used in the vehicle,
except that if the material's thickness exceeds 13mm, the specimen is cut down to that
thickness measured from the surface of the specimen closest to the occupant compartment air
space.
Where it is not possible to obtain a flat specimen because of surface curvature, the specimen is
cut to not more than 13mm in thickness at any point.
The maximum available length or width of a specimen is used where either dimension is less
than 356mm or 102mm.
4.2. The specimen is produced by cutting the material in longitudinal as well as transvers direction.
The specimen is oriented so that the surface closest to the occupant compartment air space
faces downward on the test frame.
