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.

SIST EN ISO 12402-1:2005
ISO 12402-1:2005(E)
Introduction
ISO 12402 has been prepared to give guidance on the design and application of personal flotation devices
(hereafter referred to as PFDs) for persons engaged in activities, whether in relation to their work or their
leisure, in or near water. PFDs manufactured, selected, and maintained to this standard should give a
reasonable assurance of safety from drowning to a person who is immersed in water.
Requirements for lifejackets on large, commercial seagoing ships are regulated by the International Maritime
Organisation (IMO) under the International Convention for the Safety of Life at Sea (SOLAS). ISO 12402-1
addresses lifejackets for seagoing ships.
ISO 12402 allows for the buoyancy of a PFD to be provided by a wide variety of materials or designs, some of
which may require preparation before entering the water (e.g. inflation of chambers by gas from a cylinder or
blown in orally). However, PFDs can be divided into the following two main classes:
 those which provide face up in-water support to the user regardless of physical conditions (lifejackets),
and
 those which require the user to make swimming and other postural movements to position the user with
the face out of the water (buoyancy aids).
Within these main two classes there are a number of levels of support, types of buoyancy, activation methods
for inflatable devices, and auxiliary items (such as location aids), all of which will affect the user‘s probability of
survival. Within the different types of buoyancy allowed, inflatable PFDs either provide full buoyancy without
any user intervention other than arming (i.e. PFDs inflated by a fully automatic method) or require the user to
initiate the inflation. Hybrid PFDs always provide some buoyancy but rely on the same methods as inflatable
PFDs to achieve full buoyancy. With inherently buoyant PFDs, the user only needs to put the PFD on to
achieve the performance of its class.
PFDs that do not require intervention (automatically operating PFDs) are suited to activities where persons
are likely to enter the water unexpectedly; whereas PFDs requiring intervention (e.g. manually inflated PFDs)
are only suitable for use if the user believes there will be sufficient time to produce full buoyancy, or help is
close at hand. In every circumstance, the user should ensure that the operation of the PFD is suited to the
specific application. The conformity of a PFD to this part of ISO 12402 does not imply that it is suitable for all
circumstances. The relative amount of required inspection and maintenance is another factor of paramount
importance in the choice and application of specific PFDs.
ISO 12402 is intended to serve as a guide to manufacturers, purchasers, and users of such safety equipment
in 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 on or near water, rather than for it to be stored in a locker for emergency use. Throwable
devices and flotation cushions are not covered by this part of ISO 12402. The primary function of a PFD is to
support the user in reasonable safety in the water. Within the two classes, alternative attributes make some
PFDs better suited to some circumstances than others or make them easier to use and care for than others.
Important alternatives allowed by ISO 12402 are the following:
 to provide higher levels of support (levels 100, 150, or 275) that generally float the user with greater water
clearance, enabling the user’s efforts to be expended in recovery rather than avoiding waves; or to
provide lighter or less bulky PFDs (levels 50 to 100);
 to provide the kinds of flotation (inherently buoyant foam, hybrid, and inflatable) that will accommodate
the sometimes conflicting needs of reliability and durability, in-water performance, and continuous wear;

---------------------- Page: 9 ----------------------

SIST EN ISO 12402-1:2005
ISO 12402-1:2005(E)
 to provide self-acting (inherently buoyant or automatically inflated) PFDs that float users without any
intervention on their part, except in initially donning the PFD (and regular inspection and rearming of
inflatable types), or to provide user control of the inflatable PFD’s buoyancy by manual and oral operation;
and
 to assist in detection (location aids) and recovery of the user.
PFDs provide various degrees of buoyancy in garments that are light in weight and only as bulky and
restrictive as needed for their intended use. They will need to be secure when worn, in order to provide
positive support in the water and to allow the user to swim or actively assist herself/himself or others. The PFD
selected shall ensure that the user is supported with the mouth and nose clear of the water under the
expected conditions of use and the user’s ability to assist.
Under certain conditions (such as rough water and waves), the use of watertight and multilayer clothing, which
provide (intentionally or otherwise) additional buoyancy, or the use of equipment with additional weight (such
as tool belts) will likely alter the performance of the PFD. Users, owners and employers need to ensure that
this is taken into account when selecting a PFD. Similarly, PFDs may not perform as well in extremes of
temperature, although fully approved under this part of ISO 12402. PFDs may also be affected by other
conditions of use, such as chemical exposure and welding, and may require additional protection to meet the
specific requirements of use. If the user intends taking a PFD into such conditions, she/he has to be assured
that the PFD will not be adversely affected. This part of ISO 12402 also allows a PFD to be an integral part of
a safety harness designed to conform to ISO 12401, or an integral part of a garment with other uses, for
example to provide thermal protection during immersion, in which case the complete assembly as used is
required to conform to this part of ISO 12402.
In compiling the attributes required of a PFD, consideration has also been given to the potential length of
service that the user might expect. Whilst a PFD needs to be of substantial construction and material, its
potential length of service often depends on the conditions of use and storage, which are the responsibility of
the owner, user and/or employer. Furthermore, whilst the performance tests included are believed to assess
relevant aspects of performance in real-life use, they do not accurately simulate all conditions of this. For
example, the fact that a device passes the self-righting tests in swimming attire, as described herein, does not
guarantee that it will self-right an unconscious user wearing waterproof clothing; neither can it be expected to
completely protect the airway of an unconscious person in rough water. Waterproof clothing can trap air and
further impede the self-righting action of a lifejacket.
It is essential that owners, users and employers choose those PFDs that meet the correct standards for the
circumstances in which they will be used. Manufacturers and those selling PFDs have to make clear to
prospective purchasers the product properties, alternative choices and the limitations to normal use, prior to
the purchase.
Similarly, those framing legislation regarding the use of these garments should consider carefully which class
and performance levels are most appropriate for the foreseeable conditions of use, allowing for the higher risk
circumstances. These higher risk circumstances should account for the highest probabilities of occurrence of
accidental immersion and the expected consequences in such emergencies. More information on the
selection and application is given in ISO 12402-10.

SIST EN ISO 12402-1:2005
ISO 12402-1:2005(E)
4.1.2 Buoyancy aids
These devices should be comfortable for continuous wear and provide lift, without significant face-up turning
ability, to float the conscious user with the level of support marked on the device. Buoyancy aids shall at least
be suitable for sheltered waters, but at higher performance levels may be suitable for some users in other
waters.
4.1.3 Special purpose lifejackets and buoyancy aids
These devices perform as in 4.1.1 and 4.1.2 with different levels of support, but have modifications related to
special applications for use. These applications shall not relate to essential requirements such as in-water
performance, stability and safety in use. The specific conditions for use shall be stated on their label to
maintain essential requirements.
4.2 Performance levels
4.2.1 Level 275
This level is intended primarily for offshore use under extreme conditions and by people who are carrying
significant weights and thus require additional buoyancy. It is also of value to those who are wearing clothing
which traps air and which may adversely affect the self-righting capacity of the lifejacket. It is designed to
ensure that the user is floating in the correct position with his mouth and nose clear of the surface.
See ISO 12402-2.
4.2.2 Level 150
This level is intended for general application or for use with foul weather clothing. It will turn an unconscious
person into a safe position and requires no subsequent action by the user to maintain this position.
See ISO 12402-3.
4.2.3 Level 100
This level is intended for those who may have to wait for rescue, but are likely to do so in sheltered water. The
device should not be used in rough conditions.
See ISO 12402-4.
4.2.4 Level 50
This level is intended for use by those who are competent swimmers and who are near to bank or shore, or who
have help and a means of rescue close at hand. These garments have minimal bulk, but they are of limited use
in disturbed water, and cannot be expected to keep the user safe for a long period of time. They do not have
sufficient buoyancy to protect people who are unable to help themselves. They require active participation by the
user.
