What is the T9 Certificate (ADR Conformity Certificate for Vehicles Carrying Dangerous Goods)? How does the inspection and certification process work?

The T9 Certificate is a document proving that a vehicle carrying dangerous goods, along with its tank, meets the requirements of "ADR Chapter 9". According to ADR regulations, the T9 Certificate can only be issued by an authorized institution in the country where the vehicle is registered (in Turkey, as of January 2014, the authorized institution is TSE).

"ADR Chapter 9" inspections cover the vehicle’s chassis, brake systems, electrical systems, tanks, and mechanical connections for compliance with regulations.

The ADR Conformity Certificate is issued in the name of the operator. 

The validity of the certificate is one year, and it must be renewed annually through inspections conducted by TSE. For the T9 Certificate to be granted, both vehicle and tank inspections must be up-to-date. If the tank’s intermediate inspection date has passed, a periodic inspection must be conducted. 

Tank Inspection

Tanks of vehicles transporting dangerous goods must undergo: An Intermediate Inspection every 3 years, - - If the tank undergoes repairs, modifications requiring project revisions, or damage due to an accident, an , Exceptional Inspection must be conducted. 

If the intermediate inspection date is overdue, a periodic inspection is required.

What are the characteristics of vehicles certified with a T9 Certificate (Approval Certificate for Vehicles Transporting Dangerous Goods)?

It is a vehicle specifically manufactured for transporting dangerous goods and approved by the competent authority.

A T9 Certified Vehicle is manufactured in accordance with the type of dangerous goods it is intended to transport and is equipped with special designs, materials, and components. The tank superstructure, or the chassis/truck carrying the tank superstructure, as well as the tractor unit to be coupled with an ADR-certified tanker semi-trailer, must obtain Type Approval in accordance with ADR regulations.

What are the ECE R105 Regulation and 98/91/EC Directive? Why are they necessary?

The ECE R105 Regulation and the 98/91/EC Directive define the approval requirements for vehicles designed to transport dangerous goods, specifically addressing the compliance of braking systems, electrical installations, mechanical connections, and materials used.

Vehicles designed for the transportation of dangerous goods must have a Type Approval according to ECE R105 or 98/91/EC regulations. If the tank’s test pressure is below 4 bar, the vehicle and chassis must comply with ECE R111 Regulation.
