conditions, including fatigue, to which they will be subjected during their normal use and during normal
conditions of transport.
(2) The capacity must be not more than 450 litres.
(3) The receptacle must have a double wall construction with the space between the inner and outer wall being

the receptacle.
(4) The materials of construction must have suitable mechanical properties at the service temperature.

(6) Receptacles of glass double wall construction must have an outer packaging with suitable cushioning or
absorbent materials which withstand the pressures and impacts liable to occur under normal conditions
of transport.
(7) The receptacle must be designed to remain in an upright position during transport, e.g. have a base whose
smaller horizontal dimension is greater than the height of the centre of gravity when filled to capacity or be
mounted on gimbals.
(8) The openings of the receptacles must be fitted with devices allowing gases to escape, preventing any
splashing out of liquid, and so configured that they remain in place during transport.

engraving or etching:
- The manufacturer’s name and address;
- The model number or name;
