The International Regulations for the Carriage of Dangerous Goods by Road (ADR) and the Regulations for the Transport of Dangerous Goods by Rail (RID) stipulate that pressure receptacles and tanks and their fittings must be designed, constructed, tested and equipped to endure loads and stresses occurring under normal operating conditions.
This report has:
- updated the risks and hazards of pressure receptacles and tanks affected by low temperatures.
- examined whether the ADR and RID reference standards and the standards referred to in them include a -40°C durability requirement and whether the standards allow for tank and pressure receptacle materials that would not withstand low temperatures such as -40°C.
- examined the possibility of partially or completely repealing the -40°C requirement for pressure receptacles, such as gas cylinders, and / or tanks without compromising safety and the need for conditions to ensure and guarantee the safety of transport of gas cylinders and / or tanks even at low temperatures, such as -40°C.
- identified possible accidents related to the deterioration of structural materials due to low temperatures.
The conclusion is that the -40°C durability requirements are still needed for certain pressure receptacles and tanks.
