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 19922 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee

SC 3, Piping and machinery.

Introduction

This International Standard does not apply to components for use in piping systems made of plastic. Such

components may be tested in accordance with IMO Resolution A.753 (18), Guidelines for the application of

plastic pipes on ships.

Tests with reproducible results are possible with the test bench specified in this International Standard for the

determination of fire resistance of metallic pipe components containing a resilient or elastomeric seal. As a

consequence of the connecting arrangement of the test pieces, it is possible not only to test the fire resistance

of the pipeline component’s systems but also the connection between the pipeline and pipeline component,

which may be critical. The requirement for a burner that covers a wide area and generates flames that

envelop the pipeline component under test was intended to simulate a type of flame found in practice.

The limited working pressure of 1 MPa (10 bar) and the requirement for a non-flammable test medium (water)

were implemented in order to ensure the safety of operating personnel as well as to protect the test bench in

case damage occurs at the test piece during the test.

In case of a request for a flame test under different test conditions, e.g. flame temperature, working pressure

or duration of flame application, the test is carried out in accordance with this International Standard and in

accordance with ISO 19921, but under the specific conditions requested.
