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.
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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 186 was prepared by Technical Committee ISO/TC 6, Paper, board and pulps, Subcommittee SC 2, Test
methods and quality specifications for paper and board.
This fourth edition cancels and replaces the third edition (ISO 186:1994), which has been technically revised.
Annex A forms a normative part of this International Standard.

INTERNATIONAL STANDARD ISO 186:2002(E)

Paper and board — Sampling to determine average quality
1 Scope
This International Standard specifies a method of obtaining a representative sample from a lot of paper or board,
including solid and corrugated fibreboard (see ISO 4046), for testing to determine whether or not its average quality
complies with set specifications.
It defines the conditions which apply when sampling is carried out to resolve disputes between buyer and seller
relating to a defined lot of paper or board, which has been or is being delivered.
NOTE 1 If less than 50 % of the lot is available for sampling, then sampling in terms of this International Standard will be
invalid in the absence of agreement to the contrary.
The method is unsuitable for determining the variability within a lot.
In cases where International Standards make reference to sampling according to this standard but where such
sampling is impossible, impractical or inappropriate, and where no dispute is involved, guidance is given in
normative annex A.
NOTE 2 Information on the preparation of test pieces is given in the appropriate International Standards.
2 Normative reference
The following normative document contains provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent edition of the normative document indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.
ISO 4046, Paper, board, pulp and related terms — Vocabulary
3 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
3.1
lot
aggregate of paper or board of a single kind with specified characteristics produced under conditions that are
presumed uniform, and available for sampling at one time
NOTE A lot comprises one or more nominally identical units. Where the material to be tested has already been
incorporated into a manufactured article (for example a packing case), the lot is the aggregate of such articles of a single kind,
of specified characteristics.

3.2
unit
component of a lot which may be in the form of a reel, a bale, a bundle, a parcel, the contents of a packing case, a
pallet load, etc.
See Figure 1.
3.3
sheet
area of paper or board taken from the selected units
See Figure 1.
3.4
specimen
area of paper or board cut to given dimensions, from the sheets (or manufactured articles)
See Figure 1.
3.5
sample
aggregate of all the specimens taken from the lot to provide information on the average quality of the lot and
possibly serve as a basis for a decision on the lot
See Figure 1.
3.6
test piece
piece or pieces of paper or board on which the measurement is carried out in accordance with the stipulations of
the method of test
See Figure 1.
NOTE The test piece is generally taken from a specimen. In some instances, the test piece may be the specimen itself, or
several specimens.
3.7
selected at random
taken in such a way that each part of the whole has an equal chance of being selected
4 Principle
Selection of the sheets at random from production units selected at random from a lot of paper or board. Further
subdivision and combination of these sheets to provide the specimens of the sample from which the test area or
test pieces will be taken.
