3 Testing of the device
3.1 General
Requirements, for which no special test methods are given in this standard shall be tested in one of the following
ways:
a) by tests referred to in EN ISO 15027-1 and EN 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.
3.2 Sampling
Materials and components common to a range of samples may be presented as one sample of each item to be
tested according to test methods given in 4.13 of EN ISO 15027-2:2002, if not specified otherwise by the related
test procedure.
3.3 Test subjects
3.3.1 Instruction and selection
All test persons shall be familiar with the test procedures and the use of the suit under test. They shall be informed
and instructed on the problematic of the tests. The subjects shall have a medical check-up to prove their
qualification for the tests. The tests and a reasonable pre-treatment and follow-up shall be witnessed by a
physician. All essential body functions shall be monitored and reported during the tests.
NOTE Attention is drawn to the principles of the Declaration of Helsinki (World Medical Association, 1964) as
amended at Edinburgh 2000 and to national rules and regulations such as supervision of the tests by a national
ethic commission.
3.3.2 Subject sizes
Where tests call for the use of human subjects at least 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 weights shown in Table 1, unless
otherwise specified.
Table 1 — Subject sizes

1 person over 70
1 person under 80
over 1,80
1 person over 80
3.3.3 Sex of subjects
Not more than / of the test subjects shall be of any one sex.
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 a lifejacket approved to a relevant EN 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 3.8.1.2 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 EN ISO 15027-1or
EN ISO 15027-2. However, 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 example and in no more than in one test subject. In these circumstances, two other
subjects within the same weight category and with the same sex, 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 EN ISO 15027-1 or
EN ISO 15027-2, 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.
3.4 Fuel resistance test
Place representative samples of all exterior fabrics, typical seams, apertures and components in a suitable
container and submerge them under a 100 mm head of engine fuel 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 with a
1 000 mm water head and a tensile seam strength of at least 150 N without damage.
Note any damage to the fabric or the seams.
3.5 Flammability test
3.5.1 Principle
The test suit is passed over a test pan with burning test fuel. It shall be noted if the suit burns or continues to melt
after removal.
3.5.2 Apparatus
Test pan (460 350 60) mm.
Test fuel: engine fuel.
3.5.3 Sampling
One suit system shall be subjected to the fire 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 578 mm distance of the test pan.
Fill the test pan with water to a depth of 10 mm, followed by enough petrol to make a minimum total depth of
40 mm.
Ignite the petrol 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 move the suit with a constant speed 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 whether the suit sustains burning or continues melting 6 s after being removed from the flames.

3.6 Rotating shock bin testing
3.6.1 Apparatus
The equipment used shall be that shown in Figure 2, consisting of a box of specific design made from plywood
board, the inside surface of which shall be coated with hard plastic laminate or similar. The bearing of the bin shall
be in the centre of the mass and permit the bin to be rotated freely. This rotation can be effected mechanically,
either manually or using a motor.
3.6.2 Procedure
Place the test sample in the bin through a flush panel in one of the bin's faces, then close and secure it. The bin
shall be rotated for a total of 150 revolutions at a steady rate of 6 revolutions per minute.
3.6.3 Evaluation
On completion of the rotations, the test sample shall be removed from the bin and examined by the panel for
functional integrity.
If any doubts appear further functional testing shall be performed.

3.7 Leakage measurement
3.7.1 Clean the suit to condition it prior to leakage measurement and thermal testing. The test sample shall
undergo 5 cleaning cycles according to the specification of the manufacturer.
NOTE The amount of leakage will be used as the threshold value for the thermal test.
3.7.2 Each test subject, wearing test clothing, the suit system and a lifejacket if required, shall enter the pool and
remain there for 2 min in order to completely pre-wet the suit. Where necessary the suit shall be vented of excess
air prior to this test.
