clothing including hand and arm protection and lifejackets”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by June 2018, and conflicting national standards shall be
withdrawn at the latest by June 2018.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 14225-2:2005.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of Regulation (EU) 2016/425.
For relationship with Regulation (EU) 2016/425, see informative Annexes ZA and ZB, which are an
integral part of this document.
Annex C provides details of significant technical changes between this European Standard and the
previous edition.
EN 14225 consists of the following parts under the general title Diving suits:
— Part 1: Wet suits — Requirements and test methods;
— Part 2: Dry suits — Requirements and test methods;
— Part 3: Actively heated or cooled suit systems and components — Requirements and test methods.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,

Introduction
This document for dry diving suits has been prepared to meet the needs of persons engaged in
underwater activities where the user is breathing underwater, and where thermal comfort and
required thermal protection is higher than that provided by a wet suit. A dry suit is also designed to
enable the wearers to adjust the gas volume in the suit according to their requirements.
A dry suit may be comprised of one or more pieces. Dry suits may be used in conjunction with a range of
accessories including passive and active undergarments, gloves, a hood and other head protection
equipment.
The conformity of a dry suit to this document does not imply that it is suitable for all circumstances, nor
does the standard make detailed provisions for all the special uses for which dry suits may be utilized.
A dry suit manufactured for special purposes may also:
a) provide or enable thermal insulation;
b) provide special protection.
The level of protection and performance offered by a dry suit may be altered by a number of factors,
including the water temperature, the depth of the dive, the diver’s work rate and behaviour, and the
manner in which the suit has been maintained. The adequacy of the protection provided by a dry suit
also depends upon the individual diver’s level of cold tolerance. The degree of thermal protection
offered by a dry suit is especially problematic. Appropriate material and manikin tests are being
developed and refined, but at best they will only be able to provide broad indications of the likely
protection provided by a particular suit to an individual diver.
1 Scope
This European Standard specifies the construction and performance of dry suits for wear by divers for
underwater activities where the user is breathing underwater. Marking, labelling, information meant to
be provided at the point of sale and instructions for use are also specified.
Laboratory and practical performance tests are specified.

score of 5 or more (see A.2 and A.3).
4.6.2.2 Resistance against chemicals
For suits intended to provide the user with protection against chemicals in the diving environment, the
suit material and all interfaces, e.g. seams, penetrators, closures and slide fasteners, shall restrict the
permeation and penetration of chemicals to the inside of the suit. Materials and seams shall be tested in
accordance with 5.7.2.
For a dry suit to offer chemical resistance all components of the suit shall be shown to comply fully with
this standard.
NOTE It is recognized that most suit inflation and deflation devices are unable to be tested in accordance with
5.7.2. In addition suit inflation and deflation devices would need to show that they offer protection during their
operation. As a result it is likely that only suits without inflation and deflation devices are able to meet the
requirements of this standard.
The average normalized breakthrough detection time shall be a minimum of 20 min. Materials with an
average normalized breakthrough detection time of 20 min to 60 min shall be deemed to have a low
protection index and materials with an average normalized breakthrough detection time of more than
60 min shall be deemed to have a high protection index.
The protection index, and the chemicals which the suit protects against, shall be marked on the suit [see
Clause 6 item n)].
The manufacturer shall provide instructions on effective methods for decontaminating the suit and
measuring that decontamination has been effectively achieved.
4.6.2.3 Resistance against biological hazards
For suits intended to provide the user with protection against microorganisms e.g. infective agents in
the diving environment, the suit material and all interfaces, e.g. seams, penetrators, closures and slide
fasteners, shall restrict the penetration of microorganisms into the suit. Testing shall be performed in
accordance with in EN 14126:2003, 4.1.4.1, Class 6.
For a dry suit to offer resistance against biological hazards all components of the suit shall be shown to
comply fully with this standard. It is recognized that testing in accordance with EN 14126:2003, 4.1.4.1
is not suitable for many suit components, e.g. inflation and deflation devices. Therefore this standard
only covers suits where all the components can be tested in accordance with EN 14126:2003, 4.1.4.1.
4.6.2.4 Resistance against abrasion
After the suit material has been subjected to 8 000 cycles of abrasion the material shall not leak when
tested in accordance with 5.7.4.
4.6.2.5 Visibility
If the suit manufacturer claims the suit to have enhanced visibility, there shall be affixed to the suit an
area of retro-reflective material. A total area of retro-reflective material of at least 400 cm , which
conforms to the requirements detailed in SOLAS:1974, as amended, Chapter III as amended by
IMO Resolution MSC 47(66) and LSA Code, adopted by Res A.658(16), Annex 2, issued by the
International Maritime Organization (IMO). These retro-reflective areas shall be located in at least two
positions of the suit. Preference shall be given to the upper body, and parts of the suit that will not be
covered by attachment or by other parts of the diving equipment.
When retro-reflective material attached to a suit and the same material that has not been attached to a
suit are tested in accordance with EN ISO 15027-3:2012, 3.10.6.4.2, there shall be no difference in retro-
reflectivity between the two samples.
5 Test methods
5.1 General
Three dry suits of different sizes, as stated by the manufacturer, together with material samples shall be
submitted for visual inspection (see 5.3) and testing. One suit shall undergo functional tests in sequence
in accordance with 5.4.2.1, 5.4.2.2, 5.4.2.3, 5.4.3.1 and 5.5.2. The two remaining suits shall undergo
leakage test in accordance with 5.5.2. All three suits shall undergo practical performance tests under
realistic conditions in accordance with 5.6.
One suit and suit material samples where appropriate shall undergo laboratory tests in accordance with
5.4 and 5.5. The suit material samples where appropriate shall undergo laboratory tests in accordance
with 5.4.2.1, 5.4.2.2 and 5.4.2.3.
5.2 Test sequence
The tests shall be conducted in accordance with the flow chart shown in Figure 2.
