Approval of EX/II, EX/III, FL and AT vehicles and MEMUs
NOTE: No special certificates of approval shall be required for vehicles other than EX/II, EX/III, FL,
and AT vehicles and MEMUs, apart from those required by the general safety regulations normally
applicable to vehicles in the country of origin.
EX/II, EX/III, FL and AT vehicles and MEMUs shall comply with the relevant requirements of this
Every complete or completed vehicle shall be subjected to a first inspection by the competent
authority in accordance with the administrative requirements of this Chapter to verify conformity with
the relevant technical requirements of Chapters 9.2 to 9.8.
The competent authority may waive the first inspection for a tractor for a semi-trailer type-approved

Requirements for type-approved vehicles
At the request of the vehicle manufacturer or his duly accredited representative, vehicles subject to
ADR approval according to 220.127.116.11 may be type-approved by a competent authority. The relevant
technical requirements of Chapter 9.2 shall be considered to be fulfilled if a type approval certificate
has been issued by a competent authority in accordance with ECE Regulation No. 1052 provided that
the technical requirements of the said Regulation correspond to those of Chapter 9.2 of this Part and
provided that no modification of the vehicle alters its validity. In the case of MEMUs, the type
approval mark affixed in accordance with ECE Regulation No. 105 may identify the vehicle as either
MEMU or EX/III. MEMUs need only be identified as such on the certificate of approval issued in
accordance with 9.1.3.
This type approval, granted by one Contracting Party, shall be accepted by the other Contracting
Parties as ensuring the conformity of the vehicle when the single vehicle is submitted for inspection
for ADR approval.
At the inspection for ADR approval, only those parts of the type-approved incomplete vehicle which
have been added or modified in the process of completion shall be inspected for compliance with the
applicable requirements of Chapter 9.2.

Certificate of approval
Conformity of EX/II, EX/III, FL and AT vehicles and MEMUs with the requirements of this Part is
subject to a certificate of approval (certificate of ADR approval)4 issued by the competent authority of
the country of registration for each vehicle whose inspection yields satisfactory results or has resulted
in the issue of a declaration of conformity with the requirements of Chapter 9.2 in accordance with
A certificate of approval issued by the competent authority of one Contracting Party for a vehicle

however, be related to the last nominal expiry date, if the technical inspection is performed within one
month before or after that date.
However, in the case of tanks subject to compulsory periodic inspection this provision shall not mean
that tightness (leakproofness) tests, hydraulic pressure tests or internal inspections of tanks have to be
carried out at intervals shorter than those laid down in Chapters 6.8 and 6.9.
