ISO 12402-7:2020(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;

which are then published as laws by its Member States.

ISO 12402-7:2020(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 PFDs

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 swimm
