Introduction
This International Standard was developed to provide requirements and test procedures to meet the
multi-modal United Nations Recommendations on the Transport of Dangerous Goods Model Regulations
referred to as "UN recommendations" throughout this International Standard, and successful passing
of the tests may lead to the allocation of an appropriate UN packaging mark. The UN Recommendations
have been developed by the United Nations Sub Committee of Experts on the Transport of Dangerous
Goods as a ‘model regulation’ in the light of technical progress, the advent of new substances and
materials, the exigencies of modern transport systems and, above all, the need to ensure the safety
of people, property and the environment. Amongst other aspects, the UN Recommendations cover
principles of classification and definition of classes, listing of the principal dangerous goods, general
packing requirements, testing procedures, marking, labelling or placarding, and shipping documents.
There are in addition special recommendations related to particular classes of goods.
The UN Recommendations are given legal entity by the provisions of a series of international modal
agreements and national legislation for the transport of dangerous goods. The international agreements
include the following:
— The European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR)
[1]
(covering most of Europe).
— Regulations concerning the International Carriage of Dangerous Goods by Rail (RID) (covering most
[2]
of Europe, parts of North Africa and the Middle East).
[3]
— The International Maritime Dangerous Goods Code (IMDG Code) (worldwide).
— The International Civil Aviation Organization’s Technical Instructions for the Safe Transport of
[4]
Dangerous Goods by Air (ICAO TIs) (worldwide).
The application of this International Standard will need to take account the requirements of these
international agreements and the relevant national regulations for domestic transport of dangerous
goods.
It is important to note that there will be certain modal differences from the UN Recommendations and
that the schedule for revision of the Recommendations and modal provisions may lead to temporary
inconsistencies with this International Standard.
It is noted that success in the tests and the allocation of an official UN mark do not on their own
authorize the use of a packaging for any dangerous goods, which are subject to the packing instructions
published in the various modal regulations.
This International Standard is based on Revision 21 of the UN Recommendations.

single packaging
means of packaging that does not require an inner packaging to be capable of performing its containment
function and it includes composite packaging
4 Test report
All packaging, IBCs and large packaging tested for conformity with the UN Recommendations shall be
the subject of a test report (in accordance with Annex A) which should include a specification check
prepared in accordance with Annex B, C or D. It shall be possible to specifically identify the packaging,
IBC and large packaging relative to each test report, either by the retention of uniquely referenced
packaging, IBCs and large packaging or by inclusion of sufficient photographs and/or drawings with
unique references to enable identification of the packaging, IBCs and large packaging and all its
components.
5 Selection and preparation of packaging, IBCs and large packaging for testing
For the selection and preparation of packaging, IBCs and large packaging for testing the type of contents,
(liquid, viscous or solid) is decisive.
NOTE Guidance on the determination of the type of contents given in Annex E.
5.1 Selection of packaging, IBCs and large packaging
Sufficient numbers of packaging, IBCs and large packaging per design type shall be selected for testing
and
a) shall be examined for damage which might invalidate the tests, in which event the packaging, IBCs
and large packaging shall be replaced,
b) shall be marked with a test reference which shall also be entered on the test record and later used
on the test report, and
c) the different parts of the packaging shall be identified in accordance with ISO 2206, and
d) shall be individually weighed to establish the tare or filled gross mass.
NOTE 1 The form of such weighing can vary according to whether the packaging, IBCs and large packaging
have been supplied full or empty to the test station. Where the masses of individual empty packaging, IBCs and
large packaging are recorded, it is necessary to record only a typical filled gross mass (or vice versa).
NOTE 2 Under some circumstances it can be desirable to have a range of packaging, IBCs and large packaging
tested.
Examples include
—  in a number of different sizes but of the same construction,
—  with variety of closures,
—  for use with a range of solid contents.
In such situations selective testing procedure can be used to avoid testing of every possible permutation.
The competent authority can allow this procedure after consultation.

5.2 Information to be provided with packaging, IBCs and large packaging
5.2.1 General
Each packaging, IBCs and large packaging type shall be accompanied by a specification for that design
type containing the data set outlined in Annex B, C or D and by the following additional information
contained in 5.2.2 to 5.2.6 as appropriate.
5.2.2 Test contents – Using water and non-dangerous substances
Where the tests are to be carried out using water or other non-dangerous substances, a statement of the
packing group for which the packaging is to be tested shall be provided, together with data, enabling
appropriate selection of inert test contents. For liquids, such data shall include the required maximum
relative density for the tests together with data on, for instance, the internal pressure test required. For
solids, such data shall include mass, grain size and any other relevant characteristics, for example, bulk
density, angle of repose etc., to clearly show equivalence of physical characteristics.
5.2.3 Test contents – Using the dangerous substance
Where the tests are to be carried out using the dangerous substance(s) to be transported, a statement
of their packing group and their physical characteristics shall be provided. (See for example Safety
Data Sheet) Liquids shall be defined by their relative density together with viscosity and method of
determination. Solids shall be defined by their mass and grain size and any other relevant characteristic,
for example, bulk density, angle of repose etc. to ensure physical characteristics are sufficiently
identified and included. This data shall be recorded in the test report (see Annex A).
Where the tests are carried out using the actual substance to be transported then they shall be
applicable for other substances having the same or similar characteristics.
5.2.4 Vapour pressure
For liquids, the vapour pressure (at a given temperature) of the substance to be carried or the hydraulic
pressure to be achieved during the tests shall be provided.
5.2.5 Test contents – Using articles
Where the packaging and large packaging is intended for the transport of (an) article(s), a statement of
the packing group, an appropriate description and drawing(s) of the article(s) and or photographs and
details of the way in which dummy articles were filled for the purpose of testing shall be provided.
5.2.6 Closing instructions
Any special filling or closing instructions including, where relevant, the closure torque, or taping
patterns shall be provided.
5.2.7 Handling characteristics of IBCs and large packaging

5.3 Selection of contents and filling of packaging, IBCs and large packaging prior to
testing
5.3.1 General
Single packaging, IBCs, the inner packaging of combination packaging and large packaging shall be
filled for drop and stacking tests to not less than
— 98 % of brimful capacity for liquids, and
— 95 % of brimful capacity for solids.
NOTE There can be exceptions, some flexible packaging (see 5.3.4) and some packaging designed to be
transported part full (see 5.3.5).
Packaging, IBCs, the inner packaging of combination packaging and large packaging for liquids, or
those capable of containing liquids, shall have their capacity determined as in 5.3.3. Other packages the
capacity shall be determined by other suitable means e.g. by calculation.
5.3.2 Packaging, IBC, inner packaging of combination packaging and large packaging to
contain liquids
5.3.2.1 Determination of brimful capacity
The brimful capacity is determined for example by: weighing the empty packaging/IBC/inner
packaging including closures (mass empty (m) in kg) and weighing the packaging/IBC/inner packaging
full (mass brimful (W) in kg). The packaging/IBC/inner packaging shall be filled with water until the
water just overflows and then fitting the closure and any surplus mopped up. No steps shall be taken,
e.g. by tilting or tapping the packaging/IBC/inner packaging, to enable water to penetrate into a hollow
handle/lifting feature or other design feature above the closure.
The following formula expresses the brimful capacity:
W-m
b =
d
where
b is the brimful capacity in litres;
W is the mass in kilograms, of packaging/IBC/inner packaging when brimful with water;
m is the mass in kilograms, of the empty packaging/IBC/inner packaging;
d is the density of water (=1) in kg/l.
5.3.2.2 Filling of the packaging/IBC/inner packaging
When filling test samples of the above with liquids, at least one sample shall have its capacity and filling
level determined as below. Further samples of that design type shall be filled using a dipstick calibrated
on the first sample or by mass or volume. The calculation of required volume of liquids for testing shall
be:
b×98
C=
100
where

oSIST prEN ISO 16495:2021
ISO/DIS 16495:2021(E)

C is the required volume of water in litres;
b is the brimful capacity in litres.
5.3.3 Rigid packaging, rigid IBCs, inner packaging of combination packaging and large
packaging to contain solids
Where the packaging/IBC/inner packaging is capable of containing liquids the capacity shall be
determined as in 5.3.2.1.
The calculation of required mass of solids for testing shall be:
()bd× ×95
M =
100
where
M is the required mass in kilograms, of solids;
b is the brimful capacity either measured or calculated in litres;
d is the bulk density of the test contents in kg/l.
Alternatively, for cylindrical packaging/IBC/inner packaging the level of fill required to fill the
packaging/IBC/inner packaging to at least 95 % of its brimful capacity shall be calculated from its
internal height, taking into account any reduction in height caused by the fitting of the closure.
This procedure is not suitable for bag
