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).

ISO 19912:2019(E)
Introduction
The IMO International Convention on the Safety of Life at Sea of 1974 (SOLAS 74) sets requirements
for the monthly inspection and periodic inspection of life-saving appliances, including immersion
suits, anti-exposure suits and constant wear suits. The IMO has circulated guidelines which are not
sufficiently detailed as to provide uniform application by crews on board ships and for authorisation of
servicing stations.
This document addresses the servicing of immersion suits, anti-exposure suits and constant wear suits.
It is intended for use as a companion to the IMO recommendations. It is also intended to encompass all
other relevant personal protective suits not covered by SOLAS regulations.

3.1
immersion suit
protective suit including head, hand and feet protection which reduces the body heat loss of a person
wearing it in cold water
3.2
anti-exposure suit
protective suit designed for use by rescue boat crews and marine evacuation system parties, with head
and hand protection, but the feet need not be covered, and a minimum buoyancy of 70 N
3.3
constant wear suit
protective suit designed to be routinely worn for activities on or near water in anticipation of accidental
immersion in water, but permitting physical activity to such an extent that actions can be undertaken
without undue encumbrance and thus, head, hands and feet need not be covered
3.4
dry suit
protective suit designed to protect the user against the effect of cold water immersion by precluding
the entry of water upon immersion
3.5
wet suit
protective suit designed to protect the user against the effect of cold water immersion by providing
insulation and permitting the entry and exit of water upon immersion

4 Servicing of immersion suits and anti-exposure suits
4.1 General
Immersion and anti-exposure suits encompass dry suits and wet suits intended for planned immersion
or emergency abandonment that are not normally used as constant wear.
Periodic servicing and repair of immersion and anti-exposure suits shall be carried out in accordance
with the requirements of ISO 18079-1 and the appropriate manufacturer's servicing manual and
instructions. The tests and procedures shall include, but not be limited to, those specified in 4.2.
4.2 Inspection, testing and repair
4.2.1 Check closures on storage bag as well as general condition of bag, if provided.
4.2.2 Ensure donning instructions are legible. Confirm that suit is the type and size identified on the
bag, if provided.

4.2.3 Unpack and visually inspect the suit for damage and signs of moisture or dampness. The
suit shall be dry inside and out. All outer materials shall be checked for rips, tears and punctures. All
separable inherent buoyant or insulation materials shall be removed for inspection. All inherent buoyant
or insulation materials, both fixed and separable, shall be checked for rips, tears and undue compression,
stiffening, cracking or deterioration.
Rips, tears or punctures shall be repaired in accordance with the manufacturer's instructions by an
authorized servicing station using proper parts and certified personnel. Deterioration or damage to inner
buoyancy and insulation materials shall be referred to the manufacturer for further checks and advice.
4.2.4 Check the zipper by fully opening and closing to check for ease of operation. Where lubricant
is recommended by the manufacturer, lubricate the zipper acco
