3.3 The application shall also be accompanied by:
3.3.1 A batch of five sets of retention components per door. When, however, the same sets are used
for several doors, it will be sufficient to submit one batch of sets. Sets of door retention
components which are distinguishable only because they are designed to be fitted on the left or
on the right are not regarded as different;
3.3.2 A batch of five complete latches, including actuating mechanism, per door. When, however, the
same complete latches are used for several doors, it will be sufficient to submit one batch of
latches. Latches which are distinguishable only because they are designed to be fitted on the
left or on the right are not regarded as different.
3.4 A vehicle, representative of the vehicle type to be approved, shall be submitted to the technical
service responsible for conducting approval tests.
4. APPROVAL
4.1 If the vehicle type submitted for approval pursuant to this Regulation meets the requirements of
Paragraphs 5 and 6 below, approval of that vehicle type shall be granted.
4.2 An approval number shall be assigned to each type approved. Its first two digits (02) shall
indicate the series of amendments incorporating the most recent major technical amendments
made to the Regulation at the time of issue of the approval. The same Contracting Party may
not assign the same number to the same vehicle type either if the doors are not equipped with
latches or door retention components of the same type, or if the latches and door retention
components are not fitted in the same manner as on the vehicle submitted for approval; on the
other hand, it may assign the same number to another vehicle type whose doors are equipped
with the same latches and door retention components fitted in the same manner as on the
vehicle submitted for approval.
4.3 Notice of approval or of extension or refusal of approval of a vehicle type pursuant to this
Regulation shall be communicated to the Parties to the Agreement applying this Regulation, by
means of a form conforming to the model in Annex 1 to this Regulation.
4.4 There shall be affixed, conspicuously and in a readily accessible place specified on the approval
form, to every vehicle conforming to a vehicle type approval under this Regulation, an
international approval mark consisting of:
4.4.1 a circle surrounding the letter "E" followed by the distinguishing number of the country which
has granted approval;
4.4.2 the number of this Regulation, followed by the letter "R", a dash and the approval number to the
right of the circle described in Paragraph 4.4.1.

5.3 Specifications for a Set of Retention Components for Each Door
The set of retention components for each door shall be capable of supporting the door and
withstanding a longitudinal load of 1 111 daN and a transverse load of 889 daN in both
directions.
5.4 Sliding Doors
6. TESTS
For sliding doors the track and slide combination or other supporting means shall not separate
when an outward transverse load of 889 daN is applied to the load-bearing members at the
opposite edges of the door (17,8 kN total). The test may be performed either in the vehicle or
with the door retention components in a bench test fixture.
Compliance with the provisions of Paragraphs 5.1 to 5.4 above shall be checked in accordance
with the methods set forth in Annex 3 to this Regulation.
7. MODIFICATION AND EXTENSION OF APPROVAL OF THE VEHICLE TYPE
7.1 Every modification of the vehicle type shall be notified to the administrative department which
approved the vehicle type. The department may then either:
7.1.1 consider that the modifications made are unlikely to have appreciable adverse effects and that
in any case the vehicle still complies with the requirements; or
7.1.2 require a further test report from the technical service responsible for conducting the tests.
7.2 Confirmation or refusal of approval, specifying the alterations, shall be communicated by the
procedure specified in Paragraph 4.3 above to the Parties to the Agreement which apply this
Regulation.
7.3 The competent authority issuing the extension of approval shall assign a series number to each
communication form drawn up for such an extension.
8. CONFORMITY OF PRODUCTION
8.1 Every vehicle bearing an approval mark as prescribed under this Regulation shall conform to
the vehicle type approved as regards features capable of modifying the characteristics of door
latches and door retention components or the manner in which they are fitted.
8.2 In order to verify conformity as prescribed in Paragraph 8.1 above, a sufficient number of
random checks shall be made on serially-manufactured vehicles bearing the approval mark
required by this Regulation.
8.3 As a general rule the checks as aforesaid shall be confined to the taking of measurements.
However, if necessary, the latches and door retention components shall be subjected to tests
referred to in Paragraphs 5.2 and 5.3 above, selected by the technical service responsible for
conducting approval tests.

ANNEX 2
ARRANGEMENTS OF APPROVAL MARKS
Model A
(See Paragraph 4.4 of this Regulation)
The above approval mark affixed to a vehicle shows that the vehicle type concerned has, with regard to
door latches and door retention components, been approved in the Netherlands (E 4) pursuant to
Regulation No. 11-02, as amended by the 02 series of amendments.
Model B
(See Paragraph 4.5 of this Regulation)
The above approval mark affixed to a vehicle shows that the vehicle type concerned has been approved in
the Netherlands (E 4) pursuant to Regulation No. 11-02, as amended by the 02 series of amendments and
Regulation No. 39, as amended by the 04 series of amendments.

2.1.3.2 the distance between further ends of adjacent hinges shall be 406 mm. For the case in which
the 406 mm dimension cannot be complied with, the hinges shall be arranged in such a way
that the distance between the nearest parts of two adjacent hinges shall be at least 100 mm;
2.1.3.3 a line joining the mid-points of the engaged position of the two outermost hinge pins shall be
bisected at right angles by the line of application of tensile force;
2.1.3.4 the tensile force, when applied, will stress the set of hinges approximately in the
vehicle-longitudinal direction.
2.1.4 The set of hinges shall be attached to the test fixture as positioned in the previous applicable
provision.
2.2 Transverse Load
2.2.1 The set of hinges shall be positioned on the test fixture in the closed door attitude (see
Appendix, Figure 1 to this Annex).
2.2.2 Full-length (piano) hinge: The hinge is positioned on the test fixture which shall have
adequate dimensions to enable the hinge to be fitted along all its length to satisfy the following
requirements:
2.2.2.1 the engaged length of the hinge pin shall be bisected at right angles by the line of application of
the tensile force;
2.2.2.2 the hinge assembly shall be stressed approximately in the vehicle transverse direction.
2.2.3 Multiple hinges: The hinge assemblies shall be positioned on the test fixture to satisfy the
following requirements:
2.2.3.1 the hinge pins shall be in a straight line, so that the prescribed transverse load is perpendicular
to the plane defined by the longitudinal load and the axis of the pivots, and situated in the plane
passing through the axis;
2.2.3.2 the distance between further ends of adjacent hinges shall be 406 mm. For the case in which
the 406 mm dimension cannot be complied with, the hinges shall be arranged in such a way
that the distance between the nearest parts of two adjacent hinges shall be at least 100 mm;
2.2.3.3 a line joining the mid-points of the engaged portions of the two outermost hinge pins shall be
bisected at right angles by the line of application of tensile force;
2.2.3.4 the tensile force, when applied, will stress the set of hinges approximately in the
vehicle-transverse direction.
2.2.4 The hinge system shall be attached to the test fixture as positioned in the previous applicable
provision.
2.2.5 Sliding doors: Conformity with Paragraph 5.4 of this Regulation is verified by applying the total
force of 1 778 daN to all points of attachment between the door and the structure by means of a
rigid frame, the force being applied to the centre area of the surface determined by the polygon
having as its extremities the said points of attachment.

3.5 Procedure for Determining the Resistance of Latches to Acceleration
3.5.1 Impact Test
3.5.1.1 The resistance of door locks to inertia loads may be determined either by dynamic or by
analytical means. In the case of a dynamic test, the test vehicle itself or the simulated structure
shall be secured to a chassis with the door lock system in the fully latched position. An
acceleration of 30-36 g shall be applied to the chassis for a period of at least 30 milliseconds in
a forward direction in parallel to the vehicle longitudinal axis as well as in a direction of the door
opening that is perpendicular to the above-described first direction.
3.5.1.2 When equipped with a lock device (a device to secure the latch and striker in a locked position),
ensure that the device does not come into action during the tests.
3.5.1.3 The instrumentation shall permit the recording of the acceleration value without distortion for the
phenomena having frequencies up to 100 hertz, the permissible distortion being:
+ 05
dB to 60 Hz and
− 1
+ 05
− 4
dB to 100 Hz.
4. EQUIVALENT TEST METHODS
4.1 Equivalent non-destructive test methods are permitted, provided that the results referred to in
Paragraph 5. of the Regulation can be obtained either entirely by means of the substitute test or
by calculation from the results of the substitute test. An example of calculation is reproduced in
the Appendix, Figure 4, to this Annex. If a method other than that described in Paragraph 2.
and 3. above is used, its equivalence shall be demonstrated.
