Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 23667 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 261, Packaging, in collaboration with ISO Technical Committee TC 122, Packaging, Subcommittee
SC 3, Performance requirements and tests for means of packaging, packages and unit loads (as required by
ISO/TC 122), in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna

Introduction
This International Standard was developed to provide requirements and test procedures to meet the
compatibility provisions for plastics Intermediate Bulk Containers (IBCs) to contain liquids as set out in:
⎯ the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR)
[2]
(covering most of Europe) ; and
⎯ the Regulations concerning the International Carriage of Dangerous Goods by Rail (RID) (covering most
[5]
of Europe, parts of North Africa and the Middle East) .
This procedure is an alternative option to that set out in the UN Recommendations on the Transport of
[1]
Dangerous Goods .
Plastics IBC material can be attacked by the chemical contents of the package. Such effects are caused by
different mechanisms such as environmental stress cracking (ESC), chemical degradation and swelling.
The UN recommendations and the associated modal regulations require that all IBCs shall be assessed for
compatibility with the substances which they are to contain. The UN text makes special reference to plastics
IBCs for liquids. The procedure therein contains details of testing for six months at ambient temperature with
the liquid to be carried. RID/ADR permits as an alternative the use of standard liquids to which this document
refers.
The UN recommendations are given legal entity not only to ADR and RID, but also to
[4]
⎯ the International Maritime Dangerous Goods Code (IMDG Code) (worldwide) .
These modal rules do not refer to the standard liquid tests, but they may still be acceptable as the UN
provisions do not make the six month test a mandatory requirement.
The application of this International Standard will need to take account of the requirements of these
[6], [7]
international agreements and the relevant national regulations for domestic transport of dangerous
goods.

SIST EN ISO 23667:2008
ISO 23667:2007(E)
c) individually weighed to establish the tare or the filled mass,
NOTE The form of such weighing may be varied to fit in with whether the IBCs have been supplied full or empty to
the test station. Where the masses of individual empty IBCs are recorded, it is necessary to record only a typical filled
mass (or vice versa).
d) examined for damage, etc., which might invalidate the tests.
The tests set out below should be applied to every design type of IBC, by polymer type and grade.
NOTE For selective testing, see ISO 16467:2003, Annex D.
5.2 Information to be provided with IBCs
Each IBC type shall be accompanied by specification(s) for that design type (in the appropriate format set out
in Annex C of ISO 16467:2003) and by the following additional information as relevant.
The IBC user (with the assistance, where appropriate, of the IBC manufacturer and the test laboratory) shall
identify the packaged substance. In the first instance, this process shall consist of identifying the plastics
material concerned and its possible interactions, such as swelling, environmental stress cracking (ESC) and
molecular degradation.
The specification forms for plastics IBCs should identify the material by polymer type and grade.
NOTE Where tests are carried out using the packaged substance, the test report may be applicable for other
substances having equivalent or lesser chemical effects.
5.3 Filling of IBCs prior to testing
5.3.1 General
IBCs shall be filled for testing as follows.
a) For bottom and top lift tests, IBCs shall be prepared in accordance with 7.1 and 7.2 of ISO 16467:2003.
b) For the stacking test, IBCs shall be prepared in accordance with 7.4 of ISO 16467:2003.
c) For the leakproofness and hydraulic pressure tests, IBCs shall be prepared in accordance with 7.5 and
7.6 of ISO 16467:2003.
d) For the drop test, IBCs shall be filled in accordance with 5.3.3.1 of ISO 16467:2003.
5.3.2 Filling of IBC prior to testing
Filling of IBCs shall be carried out in accordance with the following:
The IBC shall be filled to not less than 98 % of the brimful capacity. The brimful (overflow) capacity is
determined by weighing the empty IBC including closures, filling the IBC with water until the water just
overflows, fitting the closure and then weighing the IBC full. Any surplus water is mopped up. No steps shall
be taken, e.g. by tilting or tapping the IBC, to enable water to penetrate into a hollow lifting feature or other
design feature above the closure.
The following formula expresses the brimful capacity:
Wm−
b = (1)
d
© ISO 2007 – All rights reserved 5

---------------------- Page: 15 ----------------------

SIST EN ISO 23667:2008
ISO 23667:2007(E)
where
b is the brimful capacity, in litres (l);
W is the mass of the IBC when brimful with water, in kilograms (kg);
m is the mass of the empty IBC, in kilograms (kg);
d is the density of water (1,0 kg/l).
When the brimful capacity has already been determined by testing in accordance with ISO 16467, this
procedure is not necessary.
The calculation of required volume for testing shall be:
b ×98
C = (2)
100
where
C is the required volume of water, in litres (l);
b is the brimful capacity, in litres (l).
5.4 Closing IBCs
Screw type closures shall be tightened to the torque specified by the applicant where appropriate, which shall
be recorded in the test report.
Closure torque shall not differ from one test to another in the test report. If it is necessary to revise a closure
torque following a failure in one test, then all tests shall be completed using that torque setting.
All tests for a particular liquid shall be carried out at the same torque.
NOTE The closure torque may vary for different seals.
It is not necessary to apply the specified torque during the conditioning period if this affects the subsequent
performance of the seal during the BC testing.
6 Facilities for testing
6.1 General requirements
Tests shall be carried out at a testing facility capable of meeting the operational provisions of ISO/IEC 17025.
NOTE This does not imply a requirement for the test laboratory to have attained third party certification or
accreditation, but, if appropriate, such external approval may be obtained from either a national accreditation body or from
the competent authority.
Testing staff should have a knowledge of the principles of the dangerous goods regulations, as set out in the
UN recommendations.
6.2 Accuracy of measurement equipment
The accuracy of measuring equipment shall be more precise than the accuracy of the measurements in
testing, as specified in 6.3, unless otherwise approved by the competent authority. The measuring equipment
shall be calibrated in accordance with the relevant provisions of ISO/IEC 17025.
6 © ISO 2007 – All rights reserved

---------------------- Page: 16 ----------------------

SIST EN ISO 23667:2008
ISO 23667:2007(E)
6.3 Accuracy of measurements in testing
Measurement equipment shall be selected such that individual measurement results including errors in
reading and calibration shall not exceed the following tolerances:
Mass, in kilograms (kg): ± 2 %
Pressure, in kilopascals (kPa): ± 3 %
Distance / length, in millimetres (mm): ± 2 %
Temperature, in degrees Celsius (°C): ± 1 °C
Time, in minutes (min): ± 3 %
Torque, in newton·metres (Nm): ± 3 Nm or 10 %, whichever is the greater
NOTE For some measurements, the tolerances might be lower in order to have meaningful measurements, e.g.
when measuring masses or dimensions of empty IBCs.
Where only maximum or minimum values are specified in the text, tolerances are one sided, e.g. in 7.2 the
conditioning temperature may exceed 40 °C, but shall not be less.
6.4 Climatic conditions
There shall be adequate climatic facilities to meet the requirements in Clause 7 of ISO 16467:2003.
6.5 Impact surfaces for drop tests
The drop test area shall be horizontal and flat, massive enough to be immovable and rigid enough to be
non-deformable under test conditions and sufficiently large to ensure that the test package falls entirely on the
surface.
7 Conditioning procedures
7.1 Six months ambient conditioning
This test shall be carried out at ambient temperature for a period of 6 months.
For the purposes of this International Standard, ambient temperature, which shall be monitored and recorded,
is considered to be not less than 15 °C.
NOTE The competent authority may, however, allow an extended period of test for temperatures below 15 °C.
7.2 Accelerated conditioning procedure
The IBCs for test shall be conditioned for 21 days at a minimum temperature of 40 °C with each standard
liquid required.
The procedure shall be applied for polyethylene types as defined in A.3.1 and A.3.2. For other types of
polyethylene such as defined in A.3.3 and A.3.4, the approval of the competent authority shall be obtained.
7.3 Procedure at the end of the conditioning period
At the end of the conditioning period, all IBCs, except those intended to withstand the stack test for 28 days at
40 ˚C (see Table 1), shall be emptied, rinsed, inspected for damage and prepared for test in accordance with
the test procedures for plastics IBCs for liquids (ISO 16467). Testing shall commence within 21 days of the
end of the conditioning period. If emptied the packaging shall be kept closed until testing commences.
