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 15027-3 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 162, Protective clothing including hand and arm protection and lifejackets, in collaboration with
Technical Committee ISO/TC 188, Small craft, Subcommittee SC 1, Personal safety equipment, in accordance
with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 15027-3:2002), which has been technically revised.
The main technical changes are:
a) clarification that test subjects are human test subjects;
b) addition of two sites for skin temperature measurement;
c) revision of field of vision test;
d) merger of 3.10 and 3.11 into one clause and renumbering of consecutive clauses;
e) mean body temperature deleted;
f) clarification that underclothing shall be specified by the manufacturer
g) revision of requirements regarding the testing of a Class D suit.
ISO 15027 consists of the following parts, under the general title Immersion suits:
— Part 1: Constant wear suits, requirements including safety
— Part 2: Abandonment suits, requirements including safety

the following ways:
a) by tests referred to in ISO 15027-1 and ISO 15027-2; or
b) by measurement; or
c) by visual assessment; or
d) by functional test.
Prior to testing, materials and components shall be conditioned for (24 ± 0,1) h under standard atmosphere.
The temperature cycling test and the rotating shock bin test shall be carried out as pre-conditioning before any
other tests are carried out.
ISO 15027-3:2012(E)
3.2 Sampling
Where materials and components are common to a range of suits, it is permitted to test just one sample of each
material or component, unless specified otherwise by the relevant test procedure.
3.3 Human test subjects
3.3.1 Instruction and selection
All human test subjects shall be familiar with the use of the suit under test. They shall be informed and instructed
on the potential hazards of the tests. The human test subjects shall have a medical check-up to prove their
medical fitness for completing the test. See also 3.8.
NOTE Attention is drawn to the principles of the Declaration of Helsinki (World Medical Association, 1964) as
amended at Edinburgh 2000.
3.3.2 Number and sizes of human test subjects
Where tests call for the use of human test subjects, unless otherwise specified, six people shall be used, each
wearing a suit of a size category suitable for their build. Their body sizes shall be within the heights and masses
shown in Table 1.

circumstances, two other human test subjects within the same weight category and with the same gender,
wearing the same size of suit should be subjected to the same test and before the same test panel as at 3.10.3.
If this additional test is still not clearly passed as required in ISO 15027-1:2012 or ISO 15027-2:2012, then the
device shall be deemed to have failed, whilst if it is clearly passed by the additional two subjects, the test panel
may deem that the device has passed the test overall.
3.4 Fuel resistance test
Place three samples each of all exterior fabrics, typical seams, apertures and components in a suitable
container and submerge them under a 100 mm head of diesel according to EN 590 at a temperature of
(20 ± 2) °C for 24 h. After removal from the container, remove the surface oil by wiping. Subject the samples to
a hydrostatic test according to ISO 811 with a speed of 10 cm/min until 1 000 mm water head and then carry
out a tensile seam strength test according to ISO 13935-2.
3.5 Flammability test
3.5.1 Principle
The test suit is passed over a test pan with burning test fuel to determine if the suit burns or continues to melt
after removal.
3.5.2 Apparatus
Test pan, (300 ± 20) mm × (350 ± 20) mm × (65 ± 5) mm.
Test fuel: petrol or n-heptane.
3.5.3 Sampling
One suit system shall be subjected to the flammability test.
3.5.4 Procedure
Place the test pan in a draught-free area so that the suit, which is folded so that the neck part and feet are even,
travels freely across the diagonal distance of the test pan.
Fill the test pan with water to a depth of 10 mm, followed by enough petrol or n-heptane to make a minimum
total depth of 40 mm.
Ignite the petrol or n-heptane and allow to burn freely for 30 s.
Drape the suit over a suitable hanger, folded at the waist with the front outward. The bottom of the suit shall be
(250 ± 20) mm from the top edge of the test pan, see Figure 1. Secure loose parts above the lower part of the suit.
Then expose the suit with a constant speed of 0,29 m/s through the flames for 2 s. The suit shall start and finish
the test 2 m away from the closest edge of the test pan.
3.5.5 Evaluation
It shall be reported if the suit is destroyed by the flames. It shall be reported whether the suit sustains burning
or continues melting 6 s after being removed from the flames.

3.7 Leakage measurement
3.7.1 Leakage measurement for jumping
3.7.1.1 Clean the suit samples in accordance with the manufacturer’s cleaning instructions to condition
them prior to leakage measurement and thermal testing. The number of cleaning cycles recommended by the
manufacturer or five cleaning cycles shall be undertaken.
NOTE The amount of leakage will be used as the threshold value for the thermal test.
ISO 15027-3:2012(E)
3.7.1.2 Each human test subject shall wear the suit system with the standard underclothing as specified by
the manufacturer or, if not specified by the manufacturer, the standard underclothing according to 3.8.1.3. The
human test subject shall carefully enter the pool using the pool ladder and remain there for 2 min in order to
completely pre-wet the suit. The suit shall be vented of excess air prior to this test according to the instructions
of the manufacturer. If a PFD is not required and there is an inflatable element on the suit, it shall not be inflated
for this test.
3.7.1.3 The human test subject shall then climb out using the pool ladder, crouch, stretch, shake limbs and
then stand to permit excess water to run off the exterior of the suit and to remove the water from all trapped
areas. After 1 min the human test subject shall be weighed, in order to establish the human test subject’s gross
weight before the leak test starts. The weighing scales shall have a capacity up to 150 kg, and a resolution of
0,02 kg or better.
3.7.1.4 Immediately after the “pre-wetting” and weighing, a PFD shall be donned and inflated if required. The
human test subject shall then cover the mouth and nose with one hand and cross the other arm over the top,
grasping the shoulder of the suit or of the PFD. The human test subject shall then jump vertically, feet first, into
+ 05,
the pool from a height of (,45 )m .
3.7.1.5 After the jump, the human test subject shall climb out using the pool ladder, remove the PFD if used,
crouch, stretch, shake limbs and then stand to remove free water from all trapped areas. After 1 min the human
test subject shall be weighed again. The increase in weight shall be recorded, to be used together with the
amount of leakage from swimming (see 3.7.2.4) as the amount of leakage for the thermal test according to 3.8.
The suit shall then be removed to record the location of leakage in the suit and the areas of wetted underclothing.
3.7.2 Leakage measurement for swimming
3.7.2.1 Following the leakage measurement for jumping, the human test subject shall re-don the suit system
using a dry set of underclothing and vent the suit. The human test subject shall then carefully enter the pool
using the pool ladder and remain there for 2 min in order to completely pre-wet the suit.
3.7.2.2 The human test subject shall then climb out using the pool ladder, crouch, stretch, shake limbs and
then stand to permit excess water to run off the exterior of the suit and to remove the water from all trapped
areas. After 1 min the human test subject shall be weighed in order to establish the human test subject’s gross
weight before the swim starts.
3.7.2.3 Immediately after the “pre-wetting” and weighing, any hand protection provided with the suit shall be
donned and a PFD shall be donned and inflated if required. The human test subject shall then carefully re-enter
the pool using the pool ladder and swim on the back for 20 min, covering a distance of at least 350 m in this
time. The hands and arms shall be kept in the water even if not being used for propulsion.
3.7.2.4 After the swim, the human test subject shall climb out using the pool ladder, remove the hand protection
and PFD if used, crouch, stretch, shake limbs and then stand to remove free water from all trapped areas. After
1 min the human test subject shall be weighed again. The increase in weight shall be recorded, to be used
together with the amount of leakage from jumping (see 3.7.1.5) as the amount of leakage for the thermal test
according to 3.8. The suit shall then be removed to record the location of leakage in the suit and the areas of
wetted underclothing.

3.8 Thermal test
3.8.1 Using a thermal manikin
3.8.1.1 General
The test house shall validate that the thermal manikin used is able to provide thermal insulation values for
immersion suits which are within ± 10 % of the values obtained from human subject testing of the suits.
NOTE The validation should be accompanied by an exchange of experience between the manikin testing laboratories,
round robin testing, and the correlation of results between the tests with human subject and manikin.
3.8.1.2 Apparatus
A thermal manikin shall be constructed so that it
a) has a surface area and shape similar to that of a 50th percentile man and at least 9 segments representing
the head, upper torso, right and left arms, hip, right and left thigh, and right and left lower legs;
b) can be dressed in the underclothing specified by the manufacturer or in standard underclothing
