In this feature, Caroline Raine outlines the changes that are likely to be introduced in ADR 2023. These are just the draft changes expected and won’t be confirmed until later in the year. Many of the changes included derive from the 22nd revised edition of the UN Model Regulations, there are many others specific to road transport.

General Changes

There is only one new UN number:

  • UN3550 COBALT DIHYDROXIDE POWDER, containing not less than 10% respirable particles.

The UN number 1169 has been deleted and the entry for UN number 1197 has been amended to read: “1197 EXTRACTS, LIQUID, for flavour or aroma”.

There are also new special provisions 396, 397, 398 and 676.

Chapter 1 changes

Within Chapter 1 there have been a number of changes to the definitions; they have either been updated, deleted or added.

There are new paragraphs;

  • 1.1.4.7 Refillable pressure receptacles authorised by the United States of America Department of Transportation

    If the words "TEMPERATURE CONTROLLED" are part of the proper shipping name (see also 3.1.2.6), the control and emergency temperatures (see 7.1.7) shall be indicated in the transport document, as follows:

    "Control temperature: ....°C Emergency temperature: .... °C"

    The heading of that paragraph has been updated replacing “substances stabilized by temperature control” by “stabilized and temperature controlled substances”.

There are new entries for:

  • 5.4.1.1.23 Special provisions for the carriage of substances carried in molten state

    When a substance, which is solid in accordance with the definition in 1.2.1, is offered for carriage in the molten state, the qualifying word “MOLTEN” shall be added as part of the proper shipping name, unless it is already part of the proper shipping name (see 3.1.2.5).

    In the second paragraph, in the first sentence, replace “; if not, these documents shall be attached” by “(see for example 5.4.5)”.

Chapter 6

Chapter 6 has a huge number of changes in relation to ISO standards, and many editorial changes:

  • the Equivalent procedures for conformity assessment and periodic inspection and test have been amended as has the Conformity assessment, type approval and inspections procedures

  • a new Chapter has been added, Chapter 6.9 — Requirements for the design, construction, inspection and testing of portable tanks with shells made of fibre-reinforced plastics (frp) materials

  • Chapter 6.13 which was previously Chapter 3.9 has been amended — “Chapter 6.13 Requirements for the design, construction, equipment, type approval, testing and marking of fibre-reinforced plastics (frp) fixed tanks (tank-vehicles) and demountable tanks”.

Chapter 7

Chapter 7.1 also sees the word "STABILIZED" being replaced by the words "TEMPERATURE CONTROLLED".

In Chapter 7.2, V6 has been deleted and “V15 IBCs shall be carried in closed vehicles or in closed containers.” has been added.

There are a few other amends to 7.3.1.13, 7.4.1 and 7.5.1.2.

Chapter 9

ADR 9.7.9 has been amended as follows.

  • 9.7.9 Additional safety requirements concerning FL and EX/III vehicles.

    • 9.7.9.1 The following vehicles shall be equipped with an automatic fire suppression system for the compartment where the internal combustion engine propelling the vehicle is located:

      1. FL vehicles carrying liquefied and compressed flammable gases with a classification code including an F

      2. FL vehicles carrying packing group I or packing group II flammable liquids

      3. EX/III vehicles.

    • 9.7.9.2 The following vehicles shall be fitted with thermal protection capable of mitigating the propagation of a fire from all the wheels:

      1. FL vehicles carrying liquefied and compressed flammable gases with a classification code including an F;

      2. FL vehicles carrying packing group I or packing group II flammable liquids; and

      3. EX/III vehicles.

      Note: The aim is to avoid the propagation of the fire to the load, for example with thermal shields or other equivalent systems, either:

      • by direct spread from the wheel to the load, or

      • by indirect spread from the wheel to the cabin and further to the load.

Conclusions

  • These are not the final agreed changes; they still need to be formally agreed before they are fully adopted into ADR 2023.

  • This feature does not contain all of the proposed changes, just a selection of the most relevant changes — you MUST check the regulations or ask your Dangerous Goods Safety Advisor (DGSA) if you are unsure of the regulations.

  • Remember, ADR 2023 is applicable from 1 January 2023 and mandatory from July 2023.
