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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO’s adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 188, Small craft, Subcommittee SC 1,
Personal safety equipment.
This third edition cancels and replaces the second edition (ISO 15027-3:2012), which has been
technically revised.
The main changes are as follows:

— in Subclause 4.14.1, the use of a thermal manikin has been revised;
— Annex B "Test protocol and checklist for manikin testing" has been added;
— Annex C "Thermal manikin – Means of circulated water" has been added;
— Annex D "Correlation of thermal manikin systems" has been added;
— Annex E "Thermal insulation identification for suit material — Test methods" has been added;

4 Testing of the device
4.1 General
Requirements, for which no special test methods are given in this document, shall be tested in one of
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.
4.2 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.
4.3 Temperature cycling test
4.3.1 General
The temperature cycling test shall be carried out as a preconditioning before all other tests.

ISO/DIS 15027-3:2023(E)
4.3.2 Procedure
The suit, along with any attachments, shall be subjected to the following exposures with the suit packed
in accordance with the manufacturer's instructions.
If the suit is to be supplied in a sealed storage bag such as hermetically sealed or vacuum packed, the
suit samples shall be exposed to this test in this condition, including the storage method.
The suit shall be subjected to 10 alternating cycles of 8 h continuous exposures to temperatures of
(65 ± 2) °C and (– 30 ± 2) °C. These alternating temperatures need not follow immediately after each
other. On completion of the temperature cycling test, the suit shall be visually inspected for signs of
degradation to the materials or construction or to any attachments.
4.4 Rotating shock bin test
4.4.1 General
The rotating shock bin test shall be carried out as a preconditioning after the temperature cycling test
in 3.3 but before all other tests.
4.4.2 Apparatus
The equipment used shall be that shown in Figure 1, consisting of a box of specific design made from
plywood board or equivalent, 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.
4.4.3 Procedure
Place the suit in the shock bin through a flush panel in one of the shock bin's faces, then close and secure
it. The shock bin shall be operated for a total of 150 rotations at a steady rate of 6 rotations per minute.
4.4.4 Evaluation
On completion of the rotations, the suit shall be removed from the shock bin and examined by the panel
for signs of wear and tear, and for any signs that the thermal insulation material has migrated.

4.5 Tensile strength of seams
The tensile strength of seams shall be measured on separate samples using the grab method given in
ISO 13935-2, using specimens of at least 60 mm width and with at least 100 mm of material on each side
of the test point, with four similar seams for each type of seam including the seam between fastening
devices, including zip fas
