Steel or aluminium jerricans

3A1 steel, non-removable head
3A2 steel, removable head
3B1 aluminium, non-removable head
3B2 aluminium, removable head

Body and heads shall be constructed of steel sheet, of aluminium at least 99% pure or of an aluminium
base alloy. Material shall be of a suitable type and of adequate thickness in relation to the capacity of
the jerrican and to its intended use.

Chimes of steel jerricans shall be mechanically seamed or welded. Body seams of steel jerricans
intended to contain more than 40 litres of liquid shall be welded. Body seams of steel jerricans
intended to contain 40 litres or less shall be mechanically seamed or welded. For aluminium jerricans,
all seams shall be welded. Chime seams, if any, shall be reinforced by the application of a separate
reinforcing ring.

Openings in non-removable head jerricans (3A1 and 3B1) shall not exceed 7 cm in diameter. Jerricans
with larger openings are considered to be of the removable head type (3A2 and 3B2). Closures shall
be so designed that they will remain secure and leakproof under normal conditions of carriage.
Gaskets or other sealing elements shall be used with closures, unless the closure is inherently
leakproof.

If materials used for body, heads, closures and fittings are not in themselves compatible with the
contents to be carried, suitable internal protective coatings or treatments shall be applied. These
coatings or treatments shall retain their protective properties under normal conditions of carriage.

Maximum capacity of jerrican: 60 litres.

Maximum net mass: 120 kg.

Plywood drums

1D

The wood used shall be well seasoned, commercially dry and free from any defect likely to lessen the
effectiveness of the drum for the purpose intended. If a material other than plywood is used for the
manufacture of the heads, it shall be of a quality equivalent to the plywood.

At least two-ply plywood shall be used for the body and at least three-ply plywood for the heads; the
plies shall be firmly glued together by a water resistant adhesive with their grain crosswise.

The body and heads of the drum and their joins shall be of a design appropriate to the capacity of the
drum and to its intended use.

In order to prevent sifting of the contents, lids shall be lined with kraft paper or some other equivalent
material which shall be securely fastened to the lid and extend to the outside along its full
circumference.

Maximum capacity of drum: 250 litres.

Maximum net mass: 400 kg.
