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 on the meaning of ISO specific terms and expressions related to conformity

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

to Trade (TBT), see the following URL: Foreword — Supplementary information.

Introduction

Fire-proof doors shall comply with the requirements of IMO FTP-code. The standard provides reference

for design, manufacturing and inspection of hydraulic watertight hinged fireproof doors, so it is not

imperative for shipyards to implement the standard.

INTERNATIONAL STANDARD ISO 17941:2015(E)
Ships and marine technology — Hydraulic hinged
watertight fireproof doors
1 Scope

This International Standard specifies classification and designation, requirements, test method,

marking, packaging, transport, and storage of hydraulic watertight hinged fireproof doors (hereinafter

referred to as “watertight doors”).

This International Standard is applicable to the design, manufacture, and acceptance of hydraulic

watertight hinged fireproof doors with water pressure not more than 1,0 MPa used for ships, other

floating structures and ocean engineering.

3 Classification and designation
3.1 Types

3.1.1 Depending on the opening direction, watertight doors shall be classified into two types (see Figure 1):

— Type R-Right-hand watertight door (the hinge stays right when the door opens towards the observer);

— Type L-Left-hand watertight door (the hinge stays left when the door opens towards the observer).

3.1.2 According to the fire-protection rating, watertight doors shall be classified into four levels: A-60,

A-30, A-15, and A-0.
3.2 Structure and main dimensions

3.2.1 The structure and main dimensions of watertight doors shall be in accordance with Table 1

and Figure 2. The nominal size, L × B, of watertight doors is denoted by reference to the clear opening

according to ISO 3796. Watertight doors of other dimensions can be provided upon agreement between

manufacturer and purchaser.
