Introduction
This document has been prepared to meet the needs of persons engaged in certain activities on or near water.
Abandonment suits manufactured and maintained according to this document will provide protection from
cold shock and delay the onset of hypothermia.
The complete immersion system (suit and clothes worn under the suit) is intended to keep the user alive
long enough for the rescue services to find and recover them. An individual’s estimated thermal protection
time depends on water temperature and wave state as well as their physiology. This document provides the
minimum recommended insulation levels and the associated water temperatures in which the suits are to
be used.
This document is intended to serve as a minimum performance requirement for manufacturers, purchasers
and users of such safety equipment and seeks to ensure that the equipment provides effective performance
in use. The abandonment suit is not intended to jeopardize safety by causing undue discomfort which can
result in a degradation of performance.
The abandonment suit is not intended to have any features which can have a detrimental effect on the
operation of other life-saving equipment. In particular, any part of the suit which might pose a snagging
hazard is intended to be suitably covered, protected or restrained.
The primary aims in wearing an abandonment suit are:
a) to reduce the risk of cold shock and delay the onset of hypothermia;
b) to enable users to propel themselves in the water and extricate themselves from the water without it
becoming an encumbrance;
c) to make users sufficiently conspicuous in the water so as to aid their recovery.
The performance of the suit may be altered by a number of factors, including wave action or the wearing of
additional equipment. Users, owners and employers should ensure that equipment is correctly maintained
according to the manufacturer’s instructions.
A suit system may comprise one or more pieces provided that in all cases it meets the requirements of this
document as a complete system.
An abandonment suit may often be worn with a lifejacket as it will provide flotation and can help to bring a
user to a face-up position.

4 Requirements and guidance
4.1 General
4.1.1 An abandonment suit system shall not be damaged or fail in its determined function when tested in
accordance with ISO 15027-3:—, Clause 4.
When a PFD or auxiliary buoyancy is part of the suit system, it shall be tested and included as part of the
suit system.
4.1.2 The suit system shall be designed so as not to impede the user during normal use when tested in
accordance with ISO 15027-3:—, 4.15.
4.1.3 All suit samples shall undergo temperature cycling in accordance with ISO 15027-3:—, 4.3, followed
by the rotating shock bin test in accordance with ISO 15027-3:—, 4.4.
Following ISO 15027-3:—, 4.3, and ISO 15027-3:—, 4.4, and prior to all remaining tests, cleaning shall be
done according to the specification of the manufacturer in accordance with ISO 15027-3:—, 4.11.
Material, fabric and component samples shall be preconditioned as defined in 4.12.
4.1.4 The manufacturer shall specify the components of the suit system including components and
accessories, and any auxiliary buoyancy or PFD, and underclothing. The abandonment suit shall cover the
whole body with the exception of the face. The hood shall make a tight fit around the face to limit water
ingress. Hand covering shall be provided either by integral hand protection or by permanently attached
hand protection/gloves. Test by visual inspection.
The abandonment suit may incorporate additional items conforming to 4.3 and ISO 12402-8:2020, none
of which shall impair its performance with respect to the requirements of this document, either by their
presence or their use.
4.1.5 The risk of heat stress and discomfort should be taken into account in the design and use of the
suit system. This should be included in the information supplied by the manufacturer by specific advice or
warnings according to Clause 6. This should be evaluated when testing in accordance with ISO 15027-3:—,
4.15 and 4.16.
In general, the higher the protection against cold shock and hypothermia, the higher the possibility of heat
strain. The user of an abandonment suit should balance those two effects when choosing a device.
4.1.6 There shall be no visible migration of insulation material and no visible wear-and-tear damage after
the rotating shock bin test specified in ISO 15027-3:—, 4.4. Material samples are excluded from the rotating
shock bin test.
4.1.7 A suit system designed to be used with a lifejacket shall not prevent the donning of a PFD in
accordance with ISO 12402-2:2020 or ISO 12402-3:2020. The manufacturer of the suit system shall specify
the type of PFD (inflatable or inherent) to be used. PFDs in accordance with ISO 12402-4 and ISO 12402-5
are not applicable in suit systems.
4.1.8 The suit system shall be designed in such a way as to minimize the risk of snagging. Test in accordance
with ISO 15027-3:—, 4.15 and 4.16.
4.1.9 The size of the suit shall fit the size(s) of the intended user(s). If an adult universally sized suit is
provided, it shall be sized to fit at least every person between 1,50 m and 1,95 m. Test in accordance with
ISO 15027-3:—, 4.15.2.1 a).
4.2 Basic health and ergonomic requirements
4.2.1 Innocuousness
The suit system shall not adversely affect the health or hygiene of the user. The materials shall not, in
the foreseeable conditions of normal use, release substances generally known to be toxic, carcinogenic,
mutagenic, allergenic, toxic to reproduction or otherwise harmful.
The materials shall meet the requirements of ISO 13688:2013, 4.2.
NOTE More information can be found in ISO 13688. Carefully selected materials minimize the environmental
impact of the production and disposal of protective clothing (see ISO 13688:2013, Annex F).
4.2.2 Design
The design of the suit system shall facilitate its correct positioning on the user and shall ensure that it
remains in place for the foreseeable period of use, considering ambient factors, together with the movements
and postures that the wearer is likely to adopt during the course of abandonment activity. For this purpose,
appropriate means, such as adequate adjustment systems or adequate size ranges shall be provided so as to
enable the suit system to be adapted to the morphology of the user. Test in accordance with ISO 15027-3:—,
4.15 and 4.16.
4.2.3 Comfort
4.2.3.1 The suit system shall provide users with a level of comfort consistent with the level of protection
against hazards for which it is intended, the ambient conditions, the level of the user’s activity, and the
anticipated duration of use of the protective clothing.
The suit system shall not:
— have rough, sharp or hard surfaces that irritate or injure the user;
— be so tight, loose or heavy that it restricts normal movement.
This shall be evaluated when testing in accordance with ISO 15027-3:—, 4.15 and 4.16.
4.2.3.2 A suit system that imposes significant ergonomic burdens such as heat stress, or is inherently
uncomfortable because of the need to provide adequate protection, should be accompanied by specific
advice or warnings in the information supplied by the manufacturer. Specific advice on the appropriate
duration for continuous use of the clothing in the intended application(s) should be given.
4.3 Accessories
Suit systems may be equipped with accessories. Where applicable, such accessories shall conform to
ISO 12402-8:2020, and shall be tested as a part of the suit system. No accessory shall impair the suit system’s
performance.
If the suit is intended to be used without a PFD, the suit shall be provided with a permanently attached
whistle and a light.
If the suit is intended to be used with a PFD, the PFD shall be fitted with a light.
4.4 Buddy lines
A buddy line, if provided, shall be made from synthetic cord or webbing and shall be at least 1 500 mm
in length. The line shall be attached securely to the suit and have a free end with a releasable means for
attachment to another person or object, such as a loop, a snap hook, or a wooden or plastic toggle. The buddy
line, if provided, shall be readily accessible to one of the user’s gloved hands as confirmed during device
testing. The attachment means and line shall be stowed in such a way that they do not create a hazard or
affect the normal operation of the immersion suit. If hardware is provided as an attachment means, it shall
not have sharp edges. The assembly shall float in fresh water. Hardware on the buddy line shall either not be
broken, or if broken, not expose sharp edges after pull testing. Weathering testing is not required when the
buddy line is normally stowed inside a pocket,

Introduction
This document of ISO 15027 has been prepared to meet the needs of persons engaged in certain activities on
or near water.
Abandonment suits manufactured and maintained according to this document of ISO 15027 will provide
protection from cold shock and delay the onset of hypothermia.
The complete immersion system (suit and clothes worn under the suit) is intended to keep the user alive long
enough for the rescue services to find and recover them. An individual'sindividual’s estimated thermal
protection time depends on water temperature and wave state as well as their physiology. Detailed in thisThis
document of ISO 15027 areprovides the minimum recommended insulation levels and the associated water
temperatures in which the suits are to be used.
This document of ISO 15027 is intended to serve as a minimum performance requirement for manufacturers,
purchasers and users of such safety equipment and seeks to ensure that the equipment provides effective
performance in use. The abandonment suit is not intended to jeopardize safety by causing undue discomfort
which maycan result in a degradation of performance.
The abandonment suit is not intended to have noany features which wouldcan have anya detrimental effect
on the operation of other life-saving equipment that may be used. In particular, any part of the suit which
might pose a snagging hazard is intended to be suitably covered, protected or restrained.
The primary aims in wearing an abandonment suit are:
a) to reduce the risk of cold shock and delay the onset of hypothermia;
b) to enable the userusers to propel themselves in the water and extricate himselfthemselves from the water
without it becoming an encumbrance;
c) to make the userusers sufficiently conspicuous in the water so as to aid histheir recovery.
The performance of the suit may be altered by a number of factors, including wave action or the wearing of
additional equipment. Users, owners and employers should ensure that equipment is correctly maintained
according to manufacturer'sthe manufacturer’s instructions.
A suit system may comprise one or more pieces provided that in all cases it meets the requirements of this
document as a complete system.
An abandonment suit may often be worn with a lifejacket as it will provide flotation and maycan help to bring
a user to a face-up position.

Le système d'immersion complet (la combinaison et les vêtements portés sous celle-ci) est destiné à maintenir
en vie son porteur suffisamment longtemps pour permettre aux services de sauvetage de le retrouver et de
le sauver. La durée estimée de protection thermique pour un individu dépend de la température de l'eau, de
l'état de la mer ainsi que de sa physiologie. Le présent document fournit les niveaux d'isolation minimaux
recommandés et les températures de l'eau associée dans laquelle les combinaisons doivent être utilisées.
Le présent document a pour but d'établir les exigences de performances minimales pour les besoins des
fabricants, acheteurs et utilisateurs de ces équipements de sécurité, en garantissant que ces équipements
présentent à l'usage un niveau satisfaisant de performance. Les combinaisons d'abandon ne sont pas
destinées à compromettre la sécurité en provoquant une gêne excessive qui peut entraîner une dégradation
des performances.
La combinaison d'abandon n'est pas conçue pour présenter des caractéristiques qui peuvent nuire au
fonctionnement d'autres équipements de sauvetage. En particulier, toute partie de la combinaison qui
pourrait présenter un risque d'accrochage est destinée à être convenablement couverte, protégée ou
immobilisée.
Les principaux objectifs du port d'une combinaison d'abandon sont de:
a) réduire le risque de choc froid et retarder l'apparition de l'hypothermie;
b) permettre aux utilisateurs de se déplacer dans l'eau par eux-mêmes et d'en sortir sans qu'elle devienne
une entrave;
c) rendre les utilisateurs suffisamment repérables dans l'eau afin de faciliter leur sauvetage.
Les performances de la combinaison peuvent être altérées par un certain nombre de facteurs, notamment
l'action des vagues ou le port d'équipements supplémentaires. Il convient que les utilisateurs, les
propriétaires et les employeurs s'assurent que l'équipement est correctement entretenu, conformément aux
instructions du fabricant.
Un système de combinaison peut comprendre une ou plusieurs pièces à condition de satisfaire dans tous les
cas aux exigences du présent document en tant que système complet.
Une combinaison d'abandon peut souvent être portée avec un gilet de sauvetage car celui-ci apportera de la
flottabilité et peut contribuer au retournement d'un porteur en position face vers le haut.

4 Exigences et lignes directrices
4.1 Généralités
4.1.1 Une combinaison d'abandon ne doit pas être endommagée ou faire défaut dans sa fonction
déterminée lorsqu'elle est soumise à essai conformément à l'ISO 15027-3:—, Article 4.
Lorsqu'un EIF ou un auxiliaire de flottabilité fait partie du système de combinaison, il doit être soumis à
essai et inclus dans le système de combinaison.
4.1.2 Le système de combinaison doit être conçu de manière à ne pas gêner l'utilisateur pendant une
utilisation normale, lors des essais réalisés conformément à l'ISO 15027-3:—, 4.15.
4.1.3 Tous les échantillons de combinaison doivent être soumis à l'essai de cycle de température
conformément à l'ISO 15027-3:—, 4.3, suivi par l'essai de choc dans la cuve rotative conformément à
l'ISO 15027-3:—, 4.4.
Suite à l'ISO 15027-3:—, 4.3 ainsi qu'à l'ISO 15027-3:—, 4.4 et avant tous les autres essais, un nettoyage doit
être effectué selon les spécifications du fabricant, conformément à l'ISO 15027-3:—, 4.11.
Les échantillons de matériaux, textiles et composants doivent être préconditionnés comme défini en 4.12.
4.1.4 Le fabricant doit spécifier les éléments du système de combinaison, y compris les composants et
les accessoires, ainsi que tout auxiliaire de flottabilité ou EIF, et les vêtements portés sous la combinaison.
La combinaison d'abandon doit recouvrir le corps entier à l'exception du visage. La capuche doit avoir un

ajustement serré sur le visage afin de limiter les entrées d'eau. Les mains doivent être recouvertes par une
protection des mains intégrée ou par une protection des mains/gants reliée à demeure. Essais par inspection
visuelle.
La combinaison d'abandon peut comprendre des accessoires complémentaires conformes à 4.3 et à
l'ISO 12402-8:2020, lesquels ne doivent pas réduire les performances de celle-ci par rapport aux exigences

l'utilisation du système de combinaison. Il convient que les informations fournies par le fabricant incluent
des avis ou avertissements spécifiques sur ces points conformément à l'Article 6. Il convient d'évaluer ceci
lors d'essais effectués conformément à l'ISO 15027-3:—, 4.15 et 4.16.
En général, plus la protection contre les chocs froids et l'hypothermie est importante, plus la possibilité de
tension thermique sera importante. Il convient que l'utilisateur d'une combinaison d'abandon tienne compte
de ces deux effets contradictoires lors du choix d'une combinaison.
4.1.6 Il ne doit y avoir aucun signe visible de migration du matériau d'isolation ni aucun dommage visible
d'usure après l'essai de choc dans la cuve rotative spécifié dans l'ISO 15027-3:—, 4.4. Les échantillons de
matériaux sont exclus de l'essai de choc dans la cuve rotative.
4.1.7 Un système de combinaison conçu pour être utilisé avec un gilet de sauvetage ne doit pas empêcher
d'enfiler un EIF conformément à l'ISO 12402-2:2020 ou l'ISO 12402-3:2020. Le fabricant du système de
combinaison doit spécifier le type d'EIF (à flottabilité inhérente ou gonflable) à utiliser. Les EIF conformes à
l'ISO 12402-4 et à l'ISO 12402-5 ne sont pas applicables dans les systèmes de combinaisons.
4.1.8 Le système de combinaison doit être conçu de manière à réduire au minimum le risque d'accrochage.

des utilisateurs. Lorsqu'une combinaison pour adulte de taille universelle est fournie, elle doit au moins
pouvoir être portée par toute personne mesurant entre 1,50 m et 1,95 m. Essai effectué conformément à
l'ISO 15027-3:—, 4.15.2.1 a).
4.2 Exigences fondamentales relatives à la santé et à l'ergonomie
4.2.1 Innocuité
Le système de combinaison ne doit pas nuire à la santé ou l'hygiène de l'utilisateur. Les matériaux ne doivent
pas, dans les conditions prévisibles d'utilisation normale, libérer de substances généralement connues pour
être toxiques, cancérigènes, mutagènes, allergiques, reprotoxiques ou autrement nuisibles.
Les matériaux doivent satisfaire aux exigences de l'ISO 13688:2013, 4.2.
NOTE Des informations supplémentaires sont disponibles dans l'ISO 13688. Les matériaux choisis avec soin
réduisent au minimum l'impact environnemental de la production et de l'élimination des vêtements de protection
(voir l'ISO 13688:2013, Annexe F).
4.2.2 Conception
Le système de combinaison doit être conçu de façon telle qu'il puisse être placé aussi aisément que possible
sur l'utilisateur dans la position appropriée et s'y maintenir pendant la période prévisible d'utilisation,
en prenant en compte des facteurs ambiants, ainsi que des mouvements et des postures que le porteur
est susceptible d'adopter au cours de l'activité d'abandon. Dans ce but, des moyens appropriés, tels que
des systèmes de réglage adéquats ou des gammes de dimensions adéquates doivent être fournis afin de
permettre au système de combinaison de s'adapter à la morphologie de l'utilisateur. L'essai est réalisé
conformément à l'ISO 15027-3:—, 4.15 et 4.16.

4.2.3 Confort
4.2.3.1 Le système de combinaison doit fournir aux utilisateurs un niveau de confort compatible avec le
niveau de protection contre les risques pour lesquels il est prévu, avec les conditions ambiantes, avec le
niveau d'activité de l'utilisateur, et avec la durée d'utilisation prévue des vêtements de protection.
Le système de combinaison ne doit pas:
— présenter de surfaces rugueuses, aigües ou dures, qui irritent ou blessent l'utilisateur;
— être tellement serré, desserré ou lourd qu'il restreigne les mouvements normaux.
Ceci doit être évalué lors d'essais effectués conformément à l'ISO 15027-3:—, 4.15 et 4.16.
4.2.3.2 Il convient qu'un système de combinaison qui impose d'importantes contraintes ergonomiques
comme la tension thermique, ou qui est intrinsèquement inconfortable en raison de la nécessité de fournir
une protection adéquate, soit accompagné de conseils ou d'avertissements spécifiques dans les informations
fournies par le fabricant. Il convient de donner des conseils spécifiques sur la durée appropriée d'une
utilisation continue de la combinaison dans l'application ou les applications prévues.
4.3 Accessoires
Les systèmes de combinaison peuvent être équipés d'accessoires. Le cas échéant, ces accessoires doivent
être conformes à l'ISO 12402-8:2020 et être soumis à essai en tant qu'élément du système de combinaison.
Aucun accessoire ne doit entraver les performances du système de combinaison.
Si la combinaison est destinée à être portée sans EIF, celle-ci doit être munie d'un sifflet fixé en permanence
et d'une source lumineuse.
Si la combinaison est destinée à être portée avec un EIF, l'EIF doit être muni d'une source lumineuse.
4.4 Lignes de rappel
Si elle est fournie, la ligne de rappel doit être un cordage ou une sangle en fibre synthétique et doit avoir une
longueur d'au moins 1 500 mm. Cette ligne doit être solidement attachée à la combinaison et son extrémité
libre doit disposer d'un dispositif largable de liaison avec une autre personne ou un objet, tel qu'une
boucle, un mousqueton, ou un cabillot en bois ou en plastique. La ligne de rappel, si elle est fournie, doit
être immédiatement accessible par au moins une des mains de l'utilisateur portant des gants, et cela doit
être vérifié lors de l'essai du dispositif. La ligne de rappel et le dispositif d'accrochage doivent être rangés
de manière à ne pas créer de danger ni affecter l'utilisation normale de la combinaison d'immersion. Si un
système est fourni comme dispositif d'accrochage, il ne doit pas avoir de bords tranchants. L'ensemble doit
flotter en eau douce. Après l'essai de traction, les systèmes de fixation de la ligne de rappel ne doivent pas se
casser ou, s'ils se cassent, ne doivent pas avoir de bord tranchant exposé. L'essai de vieillissement n'est pas
nécessaire lorsque la ligne rappel est normalement rangée dans une poche.
Si elle est fournie, la ligne de rappel doit être soumise à essai conformément à l'ISO 12402-9:2020, 5.5.6 et
+1
supporter une charge de (750 ± 50) N pendant au moins 3 min sans aucune détérioration. La force
requise pour séparer la ligne de rappel de la combinaison doit être supérieure à 750 N et inférieure à 1 500 N.
La séparation de la ligne de rappel de la combinaison d'immersion ne doit pas altérer l'intégrité de cette
dernière. Cela doit être vérifié par inspection visuelle.
Si elle est fournie, la ligne de rappel doit être conforme à l'ISO 12402-8:2020, 5.4.
Si elle est fournie, la ligne de rappel doit porter le marquage «ISO 12402-8» et celui-ci doit être suivi des
mots «ligne de rappel» au moins dans la ou les langues officielles du pays de destination (« buddy line » en
anglais). En outre, un marquage doit être fixé sur la ligne de rappel ou à l'extérieur de la poche dans laquelle
elle est rangée, en lettres d'au moins 12 mm de hauteur, avec les mots «PAS POUR LE LEVAGE» au moins
dans la ou les langues officielles du pays de destination (« NOT FOR LIFTING » en anglais).
