REQUIREMENTS FOR THE CONSTRUCTION AND TESTING OF INTERMEDIATE BULK CONTAINERS (IBCs)

General requirements

Scope

The requirements of this Chapter apply to intermediate bulk containers (IBCs) the use of which is
expressly authorized for the carriage of certain dangerous goods according to the packing instructions
indicated in Column (8) of Table A in Chapter 3.2. Portable tanks and tank-containers which meet the
requirements of Chapter 6.7 or 6.8 respectively are not considered to be IBCs. IBCs which meet the
requirements of this Chapter are not considered to be containers for the purposes of ADR. The letters
IBC only will be used in the rest of the text to refer to intermediate bulk containers.

Exceptionally, IBCs and their service equipment not conforming strictly to the requirements herein,
but having acceptable alternatives, may be considered by the competent authority for approval. In
addition, in order to take into account progress in science and technology, the use of alternative
arrangements which offer at least equivalent safety in use in respect of compatibility with the
properties of the substances carried and equivalent or superior resistance to impact, loading and fire,
may be considered by the competent authority.

The construction, equipment, testing, marking and operation of IBCs shall be subject to acceptance by
the competent authority of the country in which the IBCs are approved.
NOTE: Parties performing inspections and tests in other countries, after the IBC has been put into
service, need not be accepted by the competent authority of the country in which the IBC has been
approved, but the inspections and tests have to be performed according to the rules specified in the
IBC’s approval.

Manufacturers and subsequent distributors of IBCs 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 IBCs as presented for carriage are capable of passing the
applicable performance tests of this Chapter.

6.5.1.4.1 (b) to indicate the nature of the material used for the outer casing.

The letter "W" may follow the IBC code. The letter "W" signifies that the IBC, although of the same
type indicated by the code, is manufactured to a specification different from those in 6.5.5 and is
considered equivalent in accordance with the requirements in 6.5.1.1.2.
