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 12401 was prepared by Technical Committee ISO/TC 188, Small craft.
This second edition cancels and replaces the first edition (ISO 12401:2004), which has been technically

Introduction
This International Standard has been prepared to meet the needs of persons afloat on recreational craft. Deck
safety harnesses and safety lines manufactured according to this International Standard will give reasonable
assurance that the wearer will remain attached to the craft.
A deck safety harness and safety line does not provide protection against falls from a height. This
International Standard does not cover the requirements of a dinghy “trapeze” harness, a windsurfing harness,
or a seat harness for fast motor boats.
This International Standard is intended to serve as a guide to manufacturers, purchasers and users of such
safety equipment by ensuring that the equipment provides an effective standard of performance in use.
Equally essential is the need for the designer to encourage the wearing of the equipment by making it
comfortable and attractive for continuous wear while afloat, rather than for it to be stowed in a locker for
emergency use. The principal reason for the existence of this International Standard is the recognition that
comfort and mobility are important factors in determining whether deck safety harnesses are worn.
The primary aims in wearing a deck safety harness are:
a) to prevent the wearer from falling into the water, and
b) to assist in recovering the wearer onto the working deck.
Preventing the wearer from actually falling into the water is dependent on the location of the attachment to the
craft and the length of the safety line. Because a correctly worn deck safety harness and safety line will, in
normal circumstances, prevent the wearer from entering the water, no consideration is given to the towing
position after a fall. The importance of ensuring a firm fit cannot be overstressed. Unless the harness is fitted
with an automatic tensioner, it remains the responsibility of the wearer to correctly adjust the harness to
achieve a firm fit.

4 Requirements for safety
4.1 General
The original effective maximum length of a safety line, measured with a measuring tape between the
attachment points, under a load of 10 kg, shall not exceed 2 m including the length of the hooks.
Design of the safety line and its attachments to the wearer shall preclude accidental incorrect attachment
resulting in more than 2 m between the strong point on the craft and the strong point on the deck safety
harness.
4.2 Materials and construction
4.2.1 Materials and components shall comply with the relevant requirements in ISO 12402-7. Sewing
threads shall be of a contrasting shade or colour in order to facilitate visual inspection.
4.2.2 All machining shall have been carried out on a lockstitching machine and securely finished off by
back-sewing for at least 13 mm, except where sewn by an automatic lockstitching machine when the first and
last stitches shall have been sewn in such a way as not to provide a natural starting point for a break in the
stitching. Sewing shall not have been carried out within 2 mm of any edge of the material. However, ends may
be oversewn if not heat-sealed. Sacrificial elements are not required to comply with this method of stitching.
4.2.3 The system of deck safety harness and/or safety line, including all metal components attached at the
intended attachment points, shall not deflect a magnetic compass by more than 1°. Testing shall be carried
out in accordance with ISO 12402-9:2006, 5.4.
4.2.4 The webbing or equivalent primary elements designed to transfer the shock load to the wearer's body
shall have a minimum width of
a) 45 mm for size 1,
b) 35 mm for size 2 and
c) 25 mm for size 3.
NOTE For a definition of sizes, see Clause 1.
4.3 General performance
4.3.1 Donning
Donning of a deck safety harness shall be obvious and simple on the briefest of instructions. This shall be
tested in accordance with 5.5.
4.3.2 Attachment point
The point of attachment of a safety line to a deck safety harness shall be positioned within 50 mm of the
central axis of the body, front or back, above the lowest point of the ribcage.
If a deck safety harness incorporates more than one point to which the safety line can be attached, it shall
either be demonstrated, using the test in 5.2, that attachment to each single point of attachment in turn meets
the requirements of this International Standard, or the harness shall be marked as specified in 6 f).

ISO 12401:2009(E)
4.3.3 Comfortable wear
A deck safety harness shall
a) be comfortable to wear for men, women and children as appropriate for the sexes and sizes for which it is
intended and when correctly adjusted,
b) be adjustable to fit the body firmly unless fitted with an automatic tensioner,
c) not be unduly bulky or heavy,
d) not restrict the vision, hearing, breathing or movement of the wearer, and
e) not contain any component nor use any method of component attachment which, in normal use, is likely
to cause injury to the user.
Testing shall be carried out in accordance with 5.5.4.2.
4.3.4 Detachability of safety lines
A safety line shall be detachable by the wearer both from the deck safety harness and from the craft when
tested in accordance with 5.5.4, except in the case of a deck safety harness intended for size 2 and size 3. In
the latter case, the safety line shall be attached in such a way, or the attachment shall be so positioned, that
the wearer cannot detach the line from the harness. When tested in accordance with 5.5, the safety line shall
be detachable from a size 2 and size 3 deck safety harness or from the craft, or from both, by an adult.
Accidental release of a safety line shall not occur when tested in accordance with 5.4.
4.3.5 Hooks
All hooks provided shall be of a self-closing type, with an opening large enough to accept, and fully close on, a
+ 0,1
cylinder of diameter 12,5 mm. There shall be no tendency for the hooks to open by any action, as
( )
0
tested in 5.4, other than deliberate release, except when a clear and permanent warning label as specified in
5.4 and 6 g) indicates that an attachment bracket is fitted to the craft.
If intermediate hooks are fitted in a safety line, the test specified in 5.4 shall be repeated using each possible
combination of points of attachment. Each repetition shall meet the requirements of this International Standard.
The hooks shall be tested in accordance with ISO 9227. When tested for a period of 160 h, the hooks shall not
be significantly affected by corrosion.
4.3.6 Holding down device
All safety harnesses shall allow the fitting of a holding-down device, which shall be at least half the width of
the flexible elements listed in 4.2.4.
4.3.7 Integrated combinations

4.4 Inspection requirements for deck safety harness sizes 1 and 2 and safety line
When tested as specified in 5.2, the deck safety harness and safety line shall comply with the following.
a) Throughout the test, the torso dummy shall be restrained securely in the harness, clear of the ground.
b) Throughout the test, all components of the deck safety harness and safety line shall remain functional
and operate as designed. Sacrificial shock absorbers may rupture, e.g. if stitching breaks. If this occurs, it
shall not affect the security of the torso dummy in the deck safety harness.
c) After the first drop test only, the slipping of any adjustment device shall not exceed 25 mm.
d) After the first drop test only, and with the load of the torso dummy or test mass relieved from the safety
line, the detachability of the safety line shall be checked in accordance with 5.5.4.
4.5 Static loading of deck safety harness size 3
When tested in accordance with 5.3, the total slippage in the safety harness adjustment devices shall not
exceed 25 mm.
5 Test methods
5.1 Magnetic properties testing
Place a direct reading magnetic compass in an undisturbed magnetic area (i.e. an area in which magnetic
items and d.c. electrical cables are not continually moved or switched). Check the compass to ensure that it
has negligible pivot friction. This can be done by deflecting the compass card 10° by means of a magnet and
then removing the deflecting force when the card should return to within 0,5° of its original position.
Present the metal components (with any hooks closed) individually to the compass on an approximately
East-to-West line, to a position where the nearest point of the component is (300 ± 10) mm horizontally from
the centre of the compass. Lightly tap the compass to eliminate the effect of friction. Record the angle in
degrees of any deflection of the compass from its position before the metal components were brought near
the compass.
5.2 Dynamic testing
5.2.1 Principle
Dynamic testing includes two tests. One for testing the strength of the complete harness and one for testing
the safety lines. For a deck safety harness and safety line that can be separated, each item is tested
separately against a reference counterpart, i.e. reference line and torso dummy for the harness and reference
harness and test mass for the safety line.
For an integrated deck safety harness and safety line, the two tests are combined. Unless the harness is part
of an integrated combination of deck safety harness and clothing, the holding-down device shall not be fitted
during the dynamic test.
NOTE These dynamic tests do not simulate reality on board a craft, but represent a strength test under overload
conditions in order to ensure sufficient durability of the components tested.
