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 16663-1 was prepared by Technical Committee ISO/TC 38, Textiles.
This second edition cancels and replaces the first edition (ISO 16663-1:2003), which has been technically
revised.
ISO 16663 consists of the following parts, under the general title Fishing nets — Method of test for the
determination of mesh size:
⎯ Part 1: Opening of mesh
⎯ Part 2: Length of mesh

INTERNATIONAL STANDARD ISO 16663-1:2009(E)

Fishing nets — Method of test for the determination of mesh
size —
Part 1:
Opening of mesh
1 Scope
This part of ISO 16663 specifies a method for the determination of the size of the mesh opening of fishing nets,
using an objective mesh gauge. It is applicable to active and passive fishing gear.
2 Normative references
The following referenced documents are indispensable for the application 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.
ISO 139, Textiles — Standard atmospheres for conditioning and testing
ISO 1107, Fishing nets — Netting — Basic terms and definitions
IEC 60529, Degrees of protection provided by enclosures (IP Code)
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
active fishing gear
fishing gear requiring movement to catch the fish
NOTE In general, mobile fishing equipment (i.e. equipment which is mobile relative to the sea bed or to the water) is
led into the path of the fish to pursue and catch them. All trawls, dredges, seine nets, purse seines and other surrounding
nets are examples of active gear.
3.2
trawl
towed net consisting of a cone-shaped body closed at the rear by a bag or cod end and widened at the
opening by wings
NOTE A trawl may be towed by one or two boats and, depending on the type, is used on the bottom or as a midwater
(pelagic) trawl.
3.3
Danish seine
funnel-shaped net (with wings and cod end) with very long ropes laid out on the sea bed and hauled in to a
vessel in the open sea
ISO 16663-1:2009(E)
3.4
purse seine
large single-panel multisection net used to encircle pelagic fish, the bottom of the net being drawn together to
enclose the encircled fish
3.5
passive fishing gear
fishing gear requiring movement of the fish in order for the fish to be caught
NOTE This gear is usually stationary equipment, often, but not always, anchored on the sea bed. Gill nets and
entangling nets are examples of passive gear.
3.6
gill net
panel of netting, usually of rectangular shape, made of thin twine or monofilament yarn, in the meshes of
which the fish are caught
NOTE The net is suspended vertically in the water by floats and sinkers.
3.7
entangling net
loosely hung vertical net that catches fish by entangling rather than enmeshing them
3.8
trammel net
bottom-set net which is made up of of three walls of netting, the two tightly hung outer walls having a larger
mesh size than the inner wall which is loosely hung between them
NOTE The fish pass through one of the outer walls and become entangled in the small meshes of the inner wall, after
which they push themselves into the second outer wall, thus forming a bag.
4 Principle
An objective mesh gauge is inserted into the mesh opening. The mesh is stretched by a movable jaw until a
pre-set measurement force is reached. The size of the mesh opening is then measured automatically.
5 Apparatus
5.1 Objective mesh gauge, complying with the requirements of 5.1.1 to 5.1.6.
5.1.1 The objective mesh gauge used for determining mesh openings shall be automatic and electrically
driven (see Figure 1). The gauge shall be able to apply selected longitudinal measuring forces, in the range
5 N to 180 N, to the meshes with a precision of 1 N. Fixed measuring forces of 10 N, 20 N, 50 N and 125 N
shall be provided. A built-in system for measuring the applied force is needed. The gauge shall have two jaws,
one fixed and one movable, each 2 mm thick with rounded edges with a radius of 1 mm, to ensure that the
jaws slip easily over the twine or yarn. A mesh shall be stretched at a constant speed of (300 ± 30) mm/min by
the movable jaw. The gauge shall be able to measure meshes from 10 mm to 300 mm and may have different,
detachable, jaws for use on small and large meshes. The measurement precision shall be 1 mm.
5.1.2 The structure of the gauge shall be rigid and shall not distort under load. The body shall be light yet
robust
