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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Baill. seeds and seedlings.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at http:// www.e lectropedia. org/
— ISO Online browsing platform: available at http:// www. iso. org/o bp
3.1
lot
specified quantity of seeds or seedlings that are physically and uniquely identifiable
3.2
primary sample
portion taken from the lot (3.1) during one single sampling action
3.3
composite sample
formed by combining and mixing all the primary samples (3.2) taken from the lot (3.1)
3.4
test sample
portion of the composite sample (3.3) to which one of the test required in this document is applied
Note 1 to entry: The test samples (3.4) may be packed in different materials meeting conditions for specific tests
[e.g. moisture or purity (3.6)].
3.5
sealed
condition whereby a container which contains seeds is closed in such a way that it cannot be opened
to get access to the seed and be closed again without either destroying the seal or leaving evidence of
tampering
Note 1 to entry: This definition refers to the sealing of seed lots, as well as of seed samples.

3.6
purity
weight of pure seed fraction over the total weight of the test sample (3.4) in per cent
Note 1 to entry: The pure seed refers to the species stated by the applicant, or found to predominate in the test,
and includes all botanical varieties and cultivars of that species.
3.7
1 000-seed weight
average weight of every 1 000 pure seeds of a test sample (3.4)
3.8
seed width
largest distance from the side of raphe to its opposite, in millimetre
Note 1 to entry: See Figure 1.
3.9
viability
index to show the potential ability of seed to germinate, or the capability of embryo to live
Note 1 to entry: It is expressed as the percentage of stained seeds in the test sample (3.4).
Note 2 to entry: It is estimated by the method of Topographical Tetrazolium Test.
3.10
stratification rate
percentage of stratified seed, determined by number, in the test sample (3.4)
Note 1 to entry: Stratified seed is the seed with embryos fully grown, endosperm volume expanded, seed coat
longitudinally fissured through the raphe by after-ripening treatment (see Figure 1).
3.11
stem diameter
boundary of aboveground and belowground of the seedling
Note 1 to entry:
