and groove joint, ship lap or rabbet joint or butt joint with at least two corrugated metal fasteners at
each joint.
Maximum net mass: 400 kg.
Plywood boxes
4D
Plywood used shall be at least 3-ply. It shall be made from well seasoned rotary cut, sliced or sawn
veneer, commercially dry and free from defects that would materially lessen the strength of the box.
The strength of the material used and the method of construction shall be appropriate to the capacity
and intended use of the box. All adjacent plies shall be glued with water resistant adhesive. Other
suitable materials may be used together with plywood in the construction of boxes. Boxes shall be
firmly nailed or secured to corner posts or ends or be assembled by equally suitable devices.
Maximum net mass: 400 kg.
Reconstituted wood boxes
4F
The walls of boxes shall be made of water resistant reconstituted wood such as hardboard, particle

Strong and good quality solid or double-faced corrugated fibreboard (single or multiwall) shall be
used, appropriate to the capacity of the box and to its intended use. The water resistance of the outer
surface shall be such that the increase in mass, as determined in a test carried out over a period of 30
minutes by the Cobb method of determining water absorption, is not greater than 155 g/m2 - see ISO
535:l991. It shall have proper bending qualities. Fibreboard shall be cut, creased without scoring, and
slotted so as to permit assembly without cracking, surface breaks or undue bending. The fluting of
corrugated fibreboard shall be firmly glued to the facings.
The ends of boxes may have a wooden frame or be entirely of wood or other suitable material.
Reinforcements of wooden battens or other suitable material may be used.
Manufacturing joins in the body of boxes shall be taped, lapped and glued, or lapped and stitched with
