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.

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.

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.

3.7.1.2 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

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
according to 3.8.1.3;
c) is capable of being heated to and controlled at a programmable uniform temperature in each segment;
d) can control and measure temperatures and power inputs and calculate, record and present the parameters;
e) can be immersed to the neck in water without causing failure in the electrical system if water leaks inside
the outer clothing;
f) can be calibrated both in and out of the water;
g) shows reproducible results with less than ± 4 % variance for three tests on the same suit system.
3.8.1.3 Standard underclothing
The underclothing to be worn in connection with the suit system shall be specified by the manufacturer. If not
specified by the manufacturer, the following standard underclothing shall be used for testing.
a) For class A suit systems:
— underwear (short-sleeved, short-legged);
— long-sleeved shirt;
— trousers (not woollen);
— woollen socks;
— appropriate footwear (if the suit is used with footwear).
The thermal insulation of the dry standard underclothing shall be no more than 1 clo measured with the
thermal manikin in air.
b) For class B, C and D suit systems: as for class A, with the addition of two woollen long-sleeved pullovers.
The underclothing shall be in good condition and shall not be altered by use or otherwise damaged. The size
of each piece of underclothing shall be suitable for the individual human test subject.
3.8.1.4 Procedure
The thermal protection provided by a suit system shall be assessed by measurement of the effective insulation
of the whole suit system and associated underclothing placed on a thermal manikin and immersed in calm but

circulated water. The suit shall be filled with the amount of leakage determined according to 3.7.1 and 3.7.2. The
immersed position shall be defined by using a male human test subject of approximately a 50th percentile size
and having an in-water weight of (55 ± 10) N, to correlate the tests with the tests using human test subjects.
Both tests shall show equivalent results.
The in-water weight of this male human test subject wearing a swim suit is taken with the tip of the chin and
bottom of the ear lobes touching the water at the bottom of the normal breathing cycle. The in-water weight is
the highest repeated value out of 10 readings or the third highest value if none is repeated.
3.8.2 Using human test subjects
3.8.2.1 Human test subjects
Human test subjects shall be volunteers meeting the requirements in 3.3.2 and shall have signed an informed
consent form. Children (person aged 16 years or younger) are not allowed to undergo thermal tests.
Due to the nature of this test, different human test subjects to those used in the other tests may be used. Each
human test subject shall be familiarized with the test procedure, medically screened, and their fat content shall
be measured prior to the start of the test. Each human test subject shall not be more than 10 % overweight or
underweight for his height and physical type as determined by a physician or physiologist or from published

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 Technical Committee ISO/TC 188, Small crafts, Subcommittee SC , and by
Technical Committee CEN/TC 162, Protective clothing including hand and arm protection and lifejackets in
collaboration.
This second edition cancels and replaces the first edition (EN ISO 15027-3:2002), which has been technically
revised.
ISO 15027 consists of the following parts, under the general title Immersion suits:
⎯ Part 1: Constant wear suits, requirements including safety (ISO/DIS 15027-1:2010)
⎯ Part 2: Abandonment suits, requirements including safety (ISO/DIS 15027-2:2010)

3.3 Test subjects
3.3.1 Instruction and selection
All test persons 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 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 subjects
Where tests call for the use of human subjects, unless otherwise specified, 6 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.

3.3.3 Gender of subjects
At least one and not more than two of the persons should be females.
3.3.4 Fitness of subjects
The persons complying with the criteria of 3.3.1 should be capable of relaxing when in water out of their depth,
be able to swim for 20 min and cover a distance of 350 m with the aid of an approved PFD as recommended
by the manufacturer and, after sufficient rest, board the platform specified in 3.11.6.2.
3.3.5 Dress of subjects
Throughout the following tests, unless otherwise specified, the test clothing described in 3.8.1.3 shall be worn
by each subject.
3.3.6 Pass/fail criteria
All samples shall pass all objective tests for the entire device to meet the requirements of
ISO/DIS 15027-1:2010 or ISO/DIS 15027-2:2010. However, for subjective test due to the high variability
between subjects and the difficulty in assessing some subjective measures, it is permitted that a device does
not completely meet the requirements of the following subjective tests in a single sample and in no more than
in one test subject. In these circumstances, two other subjects within the same weight category and with the
same gender, 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/DIS 15027-1:2010 or ISO/DIS 15027-2:2010, then
the device shall be deemed to have failed, whilst if it is clearly passed, the test panel may deem that the
device has passed the test overall.

3.7.1 Leakage measurement for jumping
3.7.1.1 Clean the suit to condition it prior to leakage measurement and thermal testing. The test sample
shall undergo 5 cycles according to the cleaning specification of the manufacturer.
NOTE The amount of leakage will be used as the threshold value for the thermal test.
3.7.1.2 Each test subject, wearing test clothing, the suit system and a PFD if required, shall enter the
pool 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 subject shall then climb out and stand for 1 min to permit excess water to run off the exterior
of the suit and to remove the water from all trapped areas. The subject shall then be weighed in order to
establish the subject's gross weight before the leak tests starts.

3.7.1.5 After the jump the subject shall climb out and stand for 1 min to remove free water from all
trapped areas and be weighed again. The increase of weight shall be recorded and to be used as the amount
of leakage for the thermal test according to 3.8.
3.7.2 Leakage measurement for swimming
After jumping and weighing the subject shall 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. The
increase of weight during the swim shall be measured in the similar method as described in 3.7.1.
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 ((Unit))
for immersion suits which are within +/- 10% of the values obtained from human subject testing of the suits.
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 representative test clothing;
c) is capable of being heated to and controlled at a programmable uniform temperature in each segment;
d) can control and measure temperatures and power inputs and calculate, record and present the
parameters;
e) can be immersed to the neck in water without causing failure in the electrical system if water leaks inside
the outer clothing;
f) can be calibrated both in and out of the water.
g) shows reproducible results with less than ± 4 % variance for three tests on the same suit system.
3.8.1.3 Test clothing
The garments to be tested in connection with the immersion suit shall be specified by the manufacturer or
shall consist of:
a) For class A suit systems
⎯ underwear (short-sleeved, short-legged)

⎯ long-sleeved shirt;
⎯ trousers (not woollen);
⎯ woollen socks;
⎯ appropriate footwear (if the suit is used with footwear).
The thermal insulation of the dry standard test clothing shall be no more than 1 Clo measured with the thermal
manikin.
b) For class B, C and D suit systems, two woollen long sleeved pullovers shall be worn additionally.
The test clothing shall be in good condition and shall not be altered by use or otherwise damaged. The size of
each piece of test clothing shall be suitable for the individual test subject.
3.8.1.4 Procedure
The thermal protection provided by a suit system shall be assessed by measurement of the effective
insulation of the whole suit system and associated test clothing placed on a thermal manikin and immersed in
calm but circulated water. The suit shall be filled with the amount of leakage determined according to 3.7.1.
The immersed position shall be defined by using a male human subject of approximately a 50th percentile
size and having an in-water weight of 55 N +/- 10 N, to correlate the tests with the tests using test subjects.
Both tests shall show equivalent results.
