ARRANGEMENT OF THE APPROVAL MARK
(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
the strength of the superstructure, been approved in the United Kingdom (E 11) pursuant to Regulation
No. 66 under approval number 002431. The first two digits of the approval number indicate that the
approval was granted in accordance with the requirements of Regulation No. 66 in its original form.
2.5. The test apparatus shall ensure the simultaneous lifting of the axles of the vehicle.
2.6. The vehicle shall be tilted without rocking and without dynamic effects until it rolls over. The
angular velocity shall not exceed 5 degrees per second (0.087 rad/sec).
2.7. High-speed photography, deformable templates or other suitable means shall be used to
determine that the requirement of Paragraph 5.1. of this Regulation has been met. This
shall be verified at not less than two positions, nominally at the front and rear of the
passenger compartment, the exact positions being at the discretion of the technical service.
Templates shall be fixed to substantially non-deformable parts of the structure.

applied to the body section by the pendulum such that at the moment of impact the direction
of motion of the pendulum makes an angle of 25° (+ 0°; - 5°) to the central longitudinal
vertical plane of the body section. The precise angle within this range may be specified by
the vehicle manufacturer.
2. TEST CONDITIONS
2.1. A sufficient number of tests shall be carried out for the technical service conducting the test
to be satisfied that the requirement specified in Paragraph 5.1. of this Regulation has been
met.

between the pillars in relation to the floor, underframe, sides and roof. Sections of such
items as luggage racks, ventilation ducting etc., where fitted, shall also be included.
2.3. Every door and opening window of the body section shall be closed and latched but not
locked. Windows and glazed bulkheads or screens may be glazed or unglazed at the
applicant's discretion.

Where more than one body section is required to be tested both shall be impacted on the
same side.
2.6. High speed photography, deformable templates or other suitable means shall be used to
determine that the requirement specified in Paragraph 5.1 of this Regulation has been met.
Templates shall be fixed to a substantially non-deformable part of the structure.
2.7. The body section to be tested shall be firmly and securely attached to the mounting frame
through the cross-bearers or parts which replace these in such a way that no significant
energy is absorbed in the support frame and its attachments during the impact.

demonstrate the acceptability of another body section which is not identical with the body
section already tested if it has many structural features in common with it.
3. The manufacturer shall declare which pillars of the superstructure are considered as
contributing to its strength and shall also declare the amount of energy (E ) that each pillar is
intended to absorb. These declarations shall meet the following criteria:
(1) ∑ E > E *
Where m is the total number of declared pillars
(2) (a) ∑ E ≥ 0.4 E *
Where n is the number of declared pillars forward of the centre of gravity of the vehicle
(b) ∑ E ≥ 0.4 E *
Where p is the number of declared pillars to the rear of the centre of gravity of the vehicle
(3) L ≥ 0.4 1
(4) L ≥ 0.4 1
