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 22488 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee

Introduction

A fire on board a ship will be fought firstly and, in most cases, only by the ship's crew. Although they may have

some training in fire-fighting activities, most crewmembers cannot be considered to be professional firefighters.

In addition, fire-fighting operations on ships take place in environmental conditions (narrow paths, limited

spaces, adverse sea conditions) in which free and easy movement is essential.

Existing International Standards for various components of firefighters' outfits, intended for use by professional

firefighters in shore-based fire-fighting operations, are not well suited to use by firefighters on board ships,

either in terms of the skill level of the user, or the environmental conditions typically found on ships. This

International Standard, while drawing heavily on those International Standards for basic performance

requirements, is intended to address the specific needs of non-professional firefighters in the shipboard

environment.

samples are required from each of three sizes, these shall comprise the largest, smallest and a middle size of

the footwear under test. All test pieces shall be conditioned in a standard atmosphere of (23 ± 2) °C and

(50 ± 5) % relative humidity for a minimum of 48 h before testing unless otherwise stated in the test method.
