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
1)
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;
1) The International Maritime Organization (IMO) is an institution with domicile in London issuing regulations
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 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.

4 Materials and components
4.1 General
4.1.1 Principles
All structural materials and components of personal flotation devices shall meet the requirements
specified in this document.
The human subject performance tests shall be witnessed by a test panel of at least 2 experts familiar
with testing and with the products specified in the relevant parts of ISO 12402.
The human subject performance tests shall be carried out under the direction of a test house’s test
panel that is experienced in these specific test procedures. These tests shall be observed by at least
2 experienced observers from the test panel and repeated with 3 experienced observers from the
4 © ISO 2020 – All rights reserved
ISO 12402-7:2020(E)
panel if there is any question about the performance observed. An observer is to be qualified by having
experience of observing (or conducting under the supervision of a qualified observer) the specific test
on at least 3 occasions.
4.1.2 Sampling
Two samples (one from each end of the range) of materials and components common to a range of
products may be submitted and the results used to cover the full range of products.
Unless otherwise specified by the test method, the sampling of components shall be representative of
the production.
4.1.3 Pass or fail criteria
4.1.3.1 All required samples shall pass all objective tests for the component or material to meet the
requirements of this document.
4.1.3.2 For any test identified as subjective or which uses human test subjects, because of the high
variability between subjects and the difficulty in assessing some subjective measures, a component may
be accepted on the basis of the following additional testing. If a component does not completely meet the
requirements of a test for a particular measurement or does so but with only one test subject, another
two samples or subjects (with similar physical characteristics, if applicable) shall be subjected to the
same test and before the same test personnel. Such subjective tests shall be witnessed by a test panel
of at least two experts familiar with testing the products specified in the ISO 12402:2020 series and
repeated with three experts if there is any question about the performance observed. If this additional
test is still not clearly passed in accordance with this document, then the component or material shall be
deemed to have failed. The test panel should deem that the component or material has passed the test
only if it has now fulfilled the test requirements completely.
4.1.4 Units of measurement
Units of measurement shall be in accordance with ISO 80000-1:2009, ISO 80000-2:2019,
ISO 80000-3:2019 and ISO 80000-4:2019.
4.1.5 Material
4.1.5.1 Non-metallic components and fabrics
Non-metallic components and fabrics shall not be damaged when tested in accordance with the relevant
Tables of this document.
4.1.5.2 Corrosion of metal components
When tested in accordance with ISO 9227:2017 for a minimum of 160 h, metal components shall not be
significantly affected by corrosion as specified in the relevant Tables of this document.
4.1.5.3 Magnetic properties
No metallic component shall affect a magnetic compass of a type commonly used in small boats by more
than 1° when placed 500 mm from the compass according to ISO 12402-9:2020, 5.4.
4.1.5.4 Innocuousness
Innocuousness material shall comply with ISO 13688:2013, 4.2.
ISO 12402-7:2020(E)
4.1.6 Sample conditioning
4.1.6.1 General
Materials and components common to a range of products may be presented as one sample of each item.
Prior to testing, materials and components shall be conditioned.
4.1.6.2 Standard conditioning
a) Except for textile products (i.e., fabric, webbing, thread, tie tape), the applicable number of samples
specified in each section shall be conditioned at (23 ± 2) °C and (50 ± 5) % relative humidity for not
less than 24 h prior to the tests.
b) For textile products, the samples shall be conditioned according to ISO 139:2005/Amd 1:2011 for
not less than 24 h.
c) If it is specified that the sample is to be tested under “wet conditions”, the sample shall be soaked
+02,
for 6 h in fresh water, or as specified by the test procedure itself.
4.1.6.3 Temperature cycling
Where required by the test method, the component or sample of fabric shall be conditioned, in its
normal storage state, and then immediately exposed for (24 ± 0,5) h at a temperature of (–30 ± 2) °C,
then for (24 ± 0,5) h at a temperature of (60 ± 2) °C. Any damage shall be assessed by visual examination
and be reported. The component or sample shall undergo ten cycles.
4.1.6.4 Accelerated weathering
Laboratory exposure of components and fabrics for lifejackets to conditions representative of elements
found in a severe outdoor environment, including light and water, shall be conducted b
