Mixed loads The maximum quantity for a mixed load is an aggregate amount of 500, using the following units: kilograms (solids, powders, etc including the weight of the packaging), litres (liquids), litres water capacity (gases). The quantity of class 9 diesel, or class 9 substances that are toxic to the aquatic environment, is in addition to the maximum quantity for a mixed load.
The maximum quantity for a mixed load is exceeded if the quantity for any class or division in the load exceeds the limit specified for that class or division.

* The maximum quantity is determined by the actual quantity of dangerous goods carried, measured in: kilograms (including the weight of the packaging) for solids, powders, etc; litres for liquids; litres water capacity of the cylinder or container for gases, except for cryogenic liquids (such as UN 1977, NITROGEN, REFRIGERATED LIQUID) where the actual quantity can easily be measured with a dip-stick or similar measuring device..

‡ Packing group means one of three groups into which dangerous goods of class or division 3, 4, 5.1, 6.1, 8 and 9 are divided for packaging purposes according to their degree of danger, and that are ranked in a decreasing order of danger: 'packing group I' (high danger), 'packing group II' (medium danger) and 'packing group III' (low danger).
