Where recycled plastics material is used for production of new packaging, the specific properties of
the recycled material shall be assured and documented regularly as part of a quality assurance
programme recognised by the competent authority. The quality assurance programme shall include a
record of proper pre-sorting and verification that each batch of recycled plastics material has the
proper melt flow rate, density, and tensile yield strength, consistent with that of the design type
manufactured from such recycled material. This necessarily includes knowledge about the packaging
material from which the recycled plastics have been derived, as well as the awareness of the prior
contents of those packagings if those prior contents might reduce the capability of new packaging
produced using that material. In addition, the packaging manufacturer's quality assurance programme
under 6.1.1.4 shall include performance of the mechanical design type test in 6.1.5 on packagings
manufactured from each batch of recycled plastics material. In this testing, stacking performance may
be verified by appropriate dynamic compression testing rather than static load testing.

Maximum net mass
4H1: 60 kg
4H2: 400 kg.

Steel, aluminium or other metal boxes

4A steel boxes
4B aluminium boxes
4N metal, other than steel or aluminium, boxes

The strength of the metal and the construction of the box shall be appropriate to the capacity of the
box and to its intended use.

Boxes shall be lined with fibreboard or felt packing pieces or shall have an inner liner or coating of
suitable material, as required. If a double seamed metal liner is used, steps shall be taken to prevent
the ingress of substances, particularly explosives, into the recesses of the seams.

Closures may be of any suitable type; they shall remain secured under normal conditions of carriage.

Maximum net mass: 400 kg.

Textile bags

5L1 without inner liner or coating
5L2 sift-proof
5L3 water resistant

The textiles used shall be of good quality. The strength of the fabric and the construction of the bag
shall be appropriate to the capacity of the bag and to its intended use.

Bags, sift-proof, 5L2: the bag shall be made sift-proof, for example by the use of:
(a) paper bonded to the inner surface of the bag by a water resistant adhesive such as bitumen; or
(b) plastics film bonded to the inner surface of the bag; or
(c) one or more inner liners made of paper or plastics material.

Bags, water resistant, 5L3: to prevent the entry of moisture the bag shall be made waterproof, for
example by the use of:
(a) separate inner liners of water resistant paper (e.g. waxed kraft paper, tarred paper or
plastics-coated kraft paper); or
(b) plastics film bonded to the inner surface of the bag; or
(c) one or more inner liners made of plastics material.

Maximum net mass: 50 kg.

Woven plastics bags

5H1 without inner liner or coating
5H2 sift-proof
5H3 water resistant

Bags shall be made from stretched tapes or monofilaments of a suitable plastics material. The strength
of the material used and the construction of the bag shall be appropriate to the capacity of the bag and
to its intended use.

If the fabric is woven flat, the bags shall be made by sewing or some other method ensuring closure of
the bottom and one side. If the fabric is tubular, the bag shall be closed by sewing, weaving or some
other equally strong method of closure.
