CHAPTER 6.6
REQUIREMENTS FOR THE CONSTRUCTION AND TESTING
OF LARGE PACKAGINGS
6.6.1.1 The requirements of this Chapter do not apply to:
- Class 2, except articles including aerosols;
- Class 6.2, except clinical waste of UN 3291;
- Class 7 packages containing radioactive material.
6.6.1.2 Large packagings shall be manufactured, tested and remanufactured under a quality
assurance programme which satisfies the competent authority in order to ensure that each manufactured or
remanufactured large packaging meets the requirements of this Chapter.
NOTE: ISO 16106:2006 “Packaging – Transport packages for dangerous goods – Dangerous goods
packagings, intermediate bulk containers (IBCs) and large packagings – Guidelines for the application of
ISO 9001” provides acceptable guidance on procedures which may be followed.
6.6.1.3 The specific requirements for large packagings in 6.6.4 are based on large packagings
currently used. In order to take into account progress in science and technology, there is no objection to the
use of large packagings having specifications different from those in 6.6.4 provided they are equally
effective, acceptable to the competent authority and able successfully to withstand the tests described
in 6.6.5. Methods of testing other than those described in these Regulations are acceptable provided they are
equivalent.
6.6.1.4 Manufacturers and subsequent distributors of packagings shall provide information regarding
procedures to be followed and a description of the types and dimensions of closures (including required
gaskets) and any other components needed to ensure that packages as presented for transport are capable of
passing the applicable performance tests of this Chapter.
6.6.2 Code for designating types of large packagings
6.6.2.1 The code used for large packagings consists of:
(a) Two Arabic numerals:
50 for rigid large packagings; or
51 for flexible large packagings; and
(b) Capital letters in Latin characters indicating the nature of the material, e.g. wood,
steel, etc. The capital letters used shall be those shown in 6.1.2.6.
6.6.2.2 The letter “W” may follow the large packaging code. The letter “W” signifies that the large
packaging, although of the same type indicated by the code, is manufactured to a specification different from
those in 6.6.4 and is considered equivalent in accordance with the requirements in 6.6.1.3.
