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 18079-2:2018(E)
Introduction

The IMO International Convention on the Safety of Life at Sea of 1974 (SOLAS 74) Chapter III

Regulation 20.8 sets requirements for the annual servicing and inspection of inflatable life rafts,

inflatable lifejackets, marine evacuation systems, and maintenance and repair of inflated rescue boats

on ships. This regulation refers to the IMO Recommendation on the conditions for the approval of

servicing stations for inflatable life rafts Assembly resolution A.761(18).

However, this resolution only provides specific standards for the servicing, maintenance and repair

of inflatable life rafts and remains silent for other types of inflatable or inflated life-saving appliances

mentioned by SOLAS Chapter III Regulation 20.8 and consequently, the application of this statutory

requirement could vary widely in practice.

The ISO 18079 series addresses those areas in which the IMO recommendation is silent, in order to

facilitate consistent implementation by maritime Administrations. It is intended for use as a companion

to the IMO recommendation and also to encompass all other relevant life-saving appliances covered by

the ISO 18079 series and not necessarily regulated by IMO instruments.

The IMO Recommendation on the conditions for the approval of servicing stations for inflatable

life rafts Assembly resolution A.761(18) specifies obligations and responsibilities for Administrations,

manufacturers and ship owners. While the ISO 18079 series covers the requirements of this resolution,

it has been rearranged and reformulated in order to enable a single entity, i.e. a servicing station, to

attain certification in accordance with the ISO 18079 series. This does not mean that the specified

obligations and responsibilities are lifted, delegated or otherwise transferred by authority from those

parties to the single entity being certified.

This document addresses the servicing of inflatable life rafts and it is intended for use as a companion

to the IMO recommendation and also to encompass all other relevant inflatable life rafts not regulated

by IMO/SOLAS.

4 Servicing of inflatable life rafts
4.1 General

Inflatable liferafts approved by a SOLAS contracting government or its recognised organisations

shall be inspected and serviced in accordance with paragraphs 4 and 5 of the annex to IMO Assembly

Resolution A.761(18), as amended. This shall include the following unless otherwise specified.

The following tests and procedures shall be carried out, except where noted otherwise, at every

servicing of an inflatable life raft fitted as life-saving appliance. Inflatable life raft servicing shall be

carried out in accordance with the appropriate manufacturer's servicing manual. Necessary procedures

shall include, but not be limited to, the following.

ISO 18079-2:2018(E)
4.2 Initial visual inspection

4.2.1 The life raft shall be visually inspected before performing the tests required according to 4.3.

This visual inspection shall, as a minimum, include the following in accordance with the instructions of

the manufacturers servicing manual.

4.2.2 The container or valise shall be inspected for damage and signs of pilferage. This shall include

inspection of outer appendages, lines, sealing, closing bands and labels.

4.2.3 The life raft container or valise shall then be opened and the still folded life raft and the interior

of the container or valise shall be inspected for signs of dampness or damage.
4.3 Test procedures
4.3.1 General

Following the visual inspections in 4.2, the life raft shall be subject to the following tests at frequencies

as described in Annex A. The tests shall be performed in accordance with the manufacturer's

servicing manual.
4.3.2 Gas inflation (GI) test

Gas inflation (GI) test shall be carried out at five-year intervals, and when undertaking a GI test, special

attention shall be paid to the effectiveness of the relief valves.

The folded life raft shall be removed from its container before activating the fitted gas inflation system.

After gas inflation has been initiated, sufficient time shall be allowed to enable the pressure in

the buoyancy tubes to become stabilized and any formation of solid particles of the inflation gas to

evaporate.

After this period, the buoyancy tubes shall, if necessary, be topped up with air, and the life raft subjected

to a pressure holding test over a period of not less than one hour, during which the pressure drop will

not exceed 5 % of the working pressure.

Life rafts associated with a marine evacuation system having been deployed and successfully inflated

in conjunction with a rotational deployment in accordance with ISO 18079-4:2018, Clause 7 shall be

deemed to have satisfied the gas inflation test.
4.3.3 Necessary additional pressure (NAP) test

Each life raft shall be subjected to the necessary additional pressure (NAP) test at yearly intervals after

the tenth year of the life raft's service life unless earlier servicing is deemed necessary as a result of

visual inspection.
The life raft shall be removed from its container or valise and from its reta
