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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at

Introduction
“B” class fire-resistant compartment systems made of composite mineral wool panels are widely used in
accommodation spaces in ships and offshore installations. Both ships and offshore installations have fire
and acoustic insulation capability as required by 1974 International Convention for the Safety of Life at Sea
(SOLAS 74) and its amendments.
This document is aligned with IMO documents, in particular SOLAS 74, IMO Resolution MSC.337 (91), IMO
MSC/Circ.917 and the International code for application of fire test procedures (FTP Code).
