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 21898 was prepared by Technical Committee ISO/TC 122, Packaging, Subcommittee SC 3,
Performance requirements and tests for means of packaging, packages and unit loads.

Packaging — Flexible intermediate bulk containers (FIBCs)
for non-dangerous goods
1 Scope
This document specifies materials, construction and design requirements, type test, certification
and marking requirements for flexible intermediate bulk containers (FIBCs) intended to contain non-
dangerous solid materials in powder, granular or paste form, and designed to be lifted from above by
integral or detachable devices.
Guidance is also provided on the selection and safe usage of FIBCs.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 General
3.1.1
flexible intermediate bulk container
FIBC
intermediate bulk container having the body made of flexible material such as woven plastic fabric or
plastics film, designed to be in contact with the contents, either directly or through an inner liner, and
collapsible when empty
3.1.2
heavy-duty reusable flexible intermediate bulk container
FIBC designed and intended to be used for a multitude of fillings and discharges, and both factory and
field repairable in such a way that the tensile strength across a repair is at least as great as that of the
original
oSIST prEN ISO 21898:2023
ISO/DIS 21898:2023(E)
3.1.3
standard-duty reusable flexible intermediate bulk container
FIBC designed and intended to be used for a limited number of fillings and discharges
Note 1 to entry: An FIBC of this category cannot be reused if damaged, i.e. it is not repairable.
Note 2 to entry: The replacement of a removable inner liner is not considered a repair.
3.1.4
single-trip flexible intermediate bulk container
FIBC designed and intended to be used for one filling only
Note 1 to entry: An FIBC of this category cannot be reused. Neither replacement of an inner liner nor repair of the
FIBC is relevant to this category.
3.1.5
FIBC type
FIBCs of like design, manufactured using like materials and methods of construction (giving at least
equal performance) to the same nominal cross-sectional dimensions
Note 1 to entry: Within a type, the circumference may be increased by up to 10 % by comparison with samples
passing a type test, provided the same geometry is maintained. Where the type has a base discharge spout,
smaller diameter discharge spouts of like design may be used.
Note 2 to entry: The presence or absence of an inner liner does not constitute a change of type.
3.1.6
safe working load
SWL
maximum load which the FIBC may carry in service, as certified
3.1.7
safety factor
SF
integer quotient between the final test load in the cyclic top lift test and the SWL value rounded down
Note 1 to entry: Safety factors may be illustrated as follows (see also B.3.3):
Example 1 Example 2
Designated SWL 500 kg 500 kg
Final load, cyclic test 2 400 kg 2 600 kg
Quotient 4,8 5,2
Integer quotient, rounded down 4 5
Note 2 to entry: The results in Example 1 above indicate a single-trip FIBC which does not meet the re
