ISO 12402-9:2020(E)
Introduction

ISO 12402 (all parts):2020 deals with personal floatation devices (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 International Standard give a reasonable assurance of safety from

drowning to a person who is immersed in water. ISO 12402 (all parts):2020 does not include the

following:

— requirements for lifejackets on seagoing ships, which are regulated by the International Maritime

Organization (IMO) under the International Convention for the Safety of Life at Sea (SOLAS);

— throwable devices and flotation cushions.

ISO 12402 (all parts):2020 allows for the buoyancy of a PFD to be provided by a variety of materials or

designs, some of which can require preparation before entering the water (e.g. inflation of chambers by

gas from a cylinder or blown in orally). 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), which all 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, if automatic operation would result in entrapment, or if 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 the ISO 12402 series: 2020 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 (all parts):2020 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. 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

provided by ISO 12402 (all parts):2020 are the following:

— to provide higher levels of support (levels 100, 150, or 275) that generally float the user with greater

water clearance, when required for increasingly severe conditions; or to provide lighter or less

bulky PFDs (levels 50 or 100);

— to provide the kinds of flotation (inherently buoyant foam, hybrid, and inflatable) that

accommodate the sometimes conflicting needs of reliability and durability, in-water performance,

and continuous wear;

SIST EN ISO 12402-9:2020
ISO 12402-9:2020(E)

— to provide automatically operating (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 need to be secure when worn, in order to provide

positive support in the water and to allow users to swim or actively assist themselves or others. The

PFD selected ensures 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) can alter the performance of the PFD. Users, owners and employers need to

ensure that this is taken into account when selecting a PFD. Similarly, it is possible that PFDs do not

perform as well in extremes of temperature, although meeting ISO 12402 (all parts):2020 requirements.

PFDs can also be affected by other conditions of use, such as chemical exposure and welding, and can

require additional protection to meet the specific requirements of use. Taking a PFD into such conditions

necessitates the assurance that the PFD will not be adversely affected. ISO 12402 (all parts):2020 also

allows a PFD to be an integral part of a safety harness designed to conform to ISO 12401:2009, 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 expected to conform to ISO 12402 (all parts):2020.

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 use. 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 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 impair 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.

The characteristics of the product properties, alternative choices and the limitations to normal use are

to be explained to potential buyers by manufacturers and distributors of PFDs prior to purchase.

Similarly, it is advised that regulators regarding the use of these garments 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 expected consequences. Requirements and

recommendations for the correct selection and application of PFDs are given in ISO 12402-10:2020.

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 12402-9 was prepared by Technical Committee ISO/TC 188, Small craft, Subcommittee SC 1, Personal

safety Equipment.

This second edition cancels and replaces the first edition (ISO 12402-9:2006, ISO 12402-9:2006/A.1:2010), of

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

Organization (IMO) under the International Convention for the Safety of Life at Sea (SOLAS).

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 or 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;

to provide automatically operating (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 use. 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 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

impair 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.
