By affixing marks in accordance with 184.108.40.206, it is certified that mass-produced packagings
correspond to the approved design type and that the requirements referred to in the approval have been
Any permeation of the substance contained in the packaging shall not constitute a danger under
normal conditions of carriage.
Requirements for packagings
1A1 non-removable head
1A2 removable head
Body and heads shall be constructed of steel sheet of a suitable type and of adequate thickness in
relation to the capacity of the drum and to its intended use.
NOTE: In the case of carbon steel drums, "suitable" steels are identified in ISO 3573:1999 "Hot
rolled carbon steel sheet of commercial and drawing qualities" and ISO 3574:1999 "Cold-reduced
carbon steel sheet of commercial and drawing qualities". For carbon steel drums below 100
litres "suitable" steels in addition to the above standards are also identified in ISO 11949:1995
"Cold-reduced electrolytic tinplate", ISO 11950:1995 "Cold-reduced electrolytic chromium/chromium
oxide-coated steel" and ISO 11951:1995 "Cold-reduced blackplate in coil form for the production of
tinplate or electrolytic chromium/chromium-oxide coated steel".
Body seams shall be welded on drums intended to contain more than 40 litres of liquid. Body seams
shall be mechanically seamed or welded on drums intended to contain solids or 40 litres or less of
Chimes shall be mechanically seamed or welded. Separate reinforcing rings may be applied.
The body of a drum of a capacity greater than 60 litres shall, in general, have at least two expanded
rolling hoops or, alternatively, at least two separate rolling hoops. If there are separate rolling hoops
they shall be fitted tightly on the body and so secured that they cannot shift. Rolling hoops shall not be
Openings for filling, emptying and venting in the bodies or heads of non-removable head (1A1) drums
shall not exceed 7 cm in diameter. Drums with larger openings are considered to be of the removable
head type (1A2). Closures for openings in the bodies and heads of drums shall be so designed and
applied that they will remain secure and leakproof under normal conditions of carriage. Closure
flanges may be mechanically seamed or welded in place. Gaskets or other sealing elements shall be
used with closures, unless the closure is inherently leakproof.
Closure devices for removable head (1A2) drums shall be so designed and applied that they will
remain secure and drums will remain leakproof under normal conditions of carriage. Gaskets or other
sealing elements shall be used with all removable heads.
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 drum: 450 litres.
Maximum net mass: 400 kg.
1B1 non-removable head
1B2 removable head
Body and heads shall be constructed 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 drum
and to its intended use.
