ISO 12401:2009(E)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 andnon-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with theInternational 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 patentrights. 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 technicallyrevised.

ISO 12401:2009(E)Introduction
This International Standard has been prepared to meet the needs of persons afloat on recreational craft. Decksafety harnesses and safety lines manufactured according to this International Standard will give reasonableassurance 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, andb)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 thecraft and the length of the safety line. Because a correctly worn deck safety harness and safety line will, innormal 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 fittedwith an automatic tensioner, it remains the responsibility of the wearer to correctly adjust the harness toachieve a firm fit.

ISO 12401:2009(E)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 functionaland 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.

5Test 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 andthen 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 fromthe centre of the compass. Lightly tap the compass to eliminate the effect of friction. Record the angle indegrees 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 partof 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.

ISO 12401:2009(E)5.4.2 Move the hook by hand as far as is possible in the following directions with the attachment point
mounted vertically:a)move forward and backward, right and left without any rotation, movement being in the horizontal plane;b)rotate in the horizontal plane by up to 360° using the attachment point as the axis, rotating both clockwise
and anticlockwise;c)rotate in the vertical plane by up to 360° about the axis of the hook, rotating both clockwise and anticlockwise;d)rotate in the vertical plane by up to 360° about an axis running through the attachment point, rotating bothclockwise and anticlockwise.

The hook fails the test if it releases from the attachment point. If the hook closure mechanism is shown toopen but not release, this will also constitute a failure, as release would probably occur with geometry ofdifferent dimensions.
No hook will fail a test on an attachment point where its use is clearly and permanently warned against inaccordance with 6 g).
