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 3.
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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 5555 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee
SC 11, Animal and vegetable fats and oils.
This third edition cancels and replaces the second edition (ISO 5555:1991), which has been technically revised.
Annexes A and B of this International Standard are for information only.

INTERNATIONAL STANDARD ISO 5555:2001(E)
Animal and vegetable fats and oils — Sampling
1 Scope
This International Standard describes methods of sampling crude or processed animal and vegetable fats and oils
(referred to as fats hereafter), whatever the origin and whether liquid or solid. It also describes the apparatus used for
this process.
NOTE Methods of sampling milk and milk products, including milk fats, are specified in ISO 707.
2 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
2.1
consignment
quantity of fat delivered at one time and covered by a particular contract or shipping document
NOTE It may be composed of one or more lots or parts of lots.
2.2
lot
identified quantity of fat, presumed to have uniform characteristics
2.3
increment
quantity of fat taken at one time from one place in a lot
2.4
bulk sample
quantity of fat obtained by combining the various increments from a lot in amounts proportional to the quantities they
represent
NOTE The bulk sample should be representative of the lot and should take account of any contractual requirements.
2.5
laboratory sample
quantity of fat, obtained from the bulk sample after suitable homogenization and reduction in size, which is
representative of the lot and intended for laboratory examination
2.6
conventional mass per volume sample
“litre weight in air” sample
quantity of fat taken for the mass of fat to be calculated from the volume
3 General principles
The object of sampling and of preparing samples is to obtain from a consignment (which may be in lots) a
manageable quantity of the fat, the properties of which correspond as closely as possible to the properties of the
consignment sampled.

ISO 5555:2001(E)
The methods of taking samples described below are intended for the guidance of experts and may be used for
a) consignments in bulk, e.g. in land tanks, ships' tanks, tank wagons, tank cars and tank containers, and
b) consignments consisting of a number of packages, e.g. barrels, drums, cases, tins, bags and bottles.
4 Requirements for apparatus
4.1 General
For a particular purpose, the choice of sampling instruments and their suitability depend on the skill of the sampler in
following the recommended procedures.
In all circumstances, it shall be borne in mind whether the sample is intended for preliminary inspection, for analysis,
or for the determination of conventional mass per volume (“litre weight in air”).
4.2 Materials
Sampling instruments, ancillary apparatus and sample containers shall be made of materials which are chemically
inert to the fat being sampled and they shall not catalyse chemical reactions.
For sampling instruments, stainless steel is the most suitable material. Aluminium may be used only when the acidity
is low but not for the storage of samples.
Only plastics which meet the requirements of the first paragraph above, at the operating temperature conditions, may
be used; polyethylene terephthalate (PET) satisfying food contact requirements is recommended.
Copper and copper alloys shall not be used nor any toxic material.
WARNING — If glass apparatus is use
