Note:
As specified in 5.0.2.15, unless otherwise approved by the appropriate national authority, the period of use permitted for plastic drums and jerricans is not more than 5 years from the date of manufacture of the receptacle.
6.2.6.3 If protection against ultra-violet radiation is required, it must be provided by the addition of carbon black or other suitable pigments or inhibitors. These additives must be compatible with the contents and remain effective throughout the life of the packaging. Where use is made of carbon black, pigments or inhibi-tors other than those used in the manufacture of the tested design type, re-testing may be waived if the carbon black content does not exceed 2% by weight or if the pigment content does not exceed 3% by weight; the content of inhibitors of ultra-violet radiation is not limited.
6.2.6.4 Additives serving purposes other than protection against ultra-violet radiation may be included in the composition of the plastic material provided that they do not adversely affect the chemical and physical properties of the material of the packaging. In such circumstances, re-testing may be waived.
6.2.6.5 The wall thickness at every point of the packag-ing must be appropriate to its capacity and intended use, taking into account the stresses to which each point is liable to be exposed.
6.2.6.6 Openings for filling, emptying and venting in the bodies or heads of non-removable head drums (1H1) and jerricans (3H1) must not exceed 7 cm in diameter. Drums and jerricans with larger openings are considered to be of the removable-head type (1H2 and 3H2). Closures for openings in the bodies or heads of drums and jerricans must be so designed and applied that they will remain secure and leak-proof under normal conditions of trans-port. Gaskets or other sealing elements must be used with closures unless the closure is inherently leak-proof.
6.2.6.7 Closure devices for removable-head drums and jerricans must be so designed and applied that they will remain secure and leak-proof under normal conditions of transport. Gaskets must be used with all removable heads unless the drum or jerrican design is such that, where the removable head is properly secured, the drum or jerrican is inherently leak-proof.
6.2.6.8 Maximum capacity of drums and jerricans:

1H1, 1H2: 450 L;

3H1, 3H2: 60 L.
6.2.6.9 Maximum net weight:

1H1, 1H2: 400 kg;

3H1, 3H2: 120 kg.
6.2.7 Metal Drums (Other than Aluminium or Steel)
6.2.7.1 This paragraph contains the specifications for:

1N1—non-removable head drum;

1N2—removable head drum.
6.2.7.2 The body and heads must be constructed of a metal or of a metal alloy other than steel or aluminium. Material must be of a suitable type and of adequate thickness in relation to the capacity of the drum and to its intended use.
6.2.7.3 Chime seams, if any, must be reinforced by the application of separate reinforcing rings. All seams, if any, must be joined (welded, soldered, etc.) in accordance with the technical state of the art for the used metal or metal alloy.
6.2.7.4 The body of a drum of a capacity greater than 60 L must in general, have at least two expanded rolling hoops or, alternatively, at least two separate rolling hoops. If there are separate rolling hoops they must be fitted tightly on the body and so secured that they cannot shift. Rolling hoops must not be spot welded.
6.2.7.5 Openings for filling, emptying and venting in the bodies or heads of non-removable head (1N1) drums must not exceed 7 cm in diameter. Drums with larger openings are considered to be of the removable head type (1N2). Closures for openings in the bodies and heads of drums must be so designed and applied that they will remain secure and leakproof under normal conditions of transport. Closure flanges must be joined in place (welded, soldered, etc.) in accordance with the technical state of the art for the used metal or metal alloy so that the seam join is leakproof. Gaskets or other sealing elements must be used with closures, unless the closure is inherently leakproof.
6.2.7.6 Closure devices for removable head drums must be so designed and applied that they will remain secure and drums will remain leakproof under normal conditions of transport. Gaskets or other sealing elements must be used with all removable heads.
6.2.7.7 Maximum capacity of drum: 450 L.
6.2.7.8 Maximum net weight: 400 kg.
6.2.8 Steel, Aluminium or Other Metal Boxes
6.2.8.1 This paragraph contains the specifications for:

4A—steel boxes;

4B—aluminium boxes;

4N— metal boxes, other than steel or aluminium.
6.2.8.2 The strength of the metal and the construction of the box must be appropriate to the capacity of the box and to its intended use.
6.2.8.3 Boxes must be lined with fibreboard or felt packing pieces as required or must have an inner liner or coating of suitable material as required. If a double seamed metal liner is used, steps must be taken to prevent the ingress of substances, particularly explosives, into the recesses of the seams.
6.2.8.4 Closures may be of any suitable type, they must remain secured under normal conditions of transport.
6.2.8.5 Maximum net weight: 400 kg.
6.2.9 Boxes of Natural Wood or Wooden Box
6.2.9.1 This paragraph contains the specifications for:

4C1—ordinary boxes of natural wood;

4C2—sift-proof walled boxes of natural wood.
6.2.9.2 The wood used must be well seasoned, com-mercially dry and free from defects that would materially lessen the strength of any part of the box. The strength of the material used and the method of construction must be appropriate to the capacity and intended use of the box. The tops and bottoms may be made of water resistant reconstituted wood such as hardboard, particle board or other suitable type.
