Fire test procedures for divisional elements that are typically used in oil, gas and petrochemical industries — Part 2: Additional procedures for pipe penetration and cable transit sealing systems
This document specifies a test methodology for determining the fire resistance of divisional elements with a fire protection system when subjected to cellulosic or hydrocarbon-pool type fire exposure conditions. This document describes additional test procedures for penetration and cable transit sealing systems intended for non-marine applications but suitable for offshore fixed and mobile installations. The test data thus obtained enables subsequent classification on the basis of the duration for which the performance of the divisional element under these conditions satisfies specified criteria.
Méthodes d'essais au feu des éléments de séparation habituellement utilisés dans les industries pétrolières, gazières et pétrochimiques — Partie 2: Modes opératoires supplémentaires pour les systèmes de calfeutrement de traversées de câbles et de trémies de tuyaux
Ce document spécifie une méthodologie d’essai pour déterminer la résistance au feu des éléments de séparation avec un système de protection contre l’incendie lorsqu’ils sont soumis à des conditions d’exposition au feu de type cellulosique ou de nappes d’hydrocarbures. Le présent document décrit les modes opératoires d’essai supplémentaire pour les systèmes de calfeutrement de trémies et de traversées de câbles destinés aux applications non maritimes, mais adaptés aux installations fixes et mobiles en mer. Les données d’essai ainsi obtenues permettent une classification ultérieure sur la base de la durée pendant laquelle la performance de l’élément de séparation satisfait aux critères spécifiés dans ces conditions.

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).

Introduction
This document describes a test procedure to assess the protection afforded by fire protection materials
and systems to divisional elements. It gives an indication of how fire protection materials will perform
when exposed to a set of specified fire conditions.
The classification of divisional elements (bulkheads and decks) in the marine industry [i.e. ships
as defined by the International Maritime Organisation (IMO) and Safety of Life and Sea (SOLAS)
convention] is primarily undertaken in accordance with classification society procedures through
testing to the fire test procedures (FTP) codes IMO resolution 307(88), formerly IMO A.754(18).
Historically, FTP-code-compliant test evidence has been used to support non-marine applications by
implementing hydrocarbon time temperature regime profiles. To reduce the burden on industry, this
document is compatible with FTP codes IMO resolution MSC 307(88) where relevant, allowing the use
of both IMO and ISO test procedures for specific classification ratings.

transit sealing systems
1 Scope
ISO 20902-1 specifies a test methodology for determining the fire resistance of divisional elements
with a fire protection system when subjected to cellulosic or hydrocarbon-pool type fire exposure
conditions. This document describes additional test procedures for penetration and cable transit sealing
systems intended for non-marine applications but suitable for offshore fixed and mobile installations.
The test data thus obtained enables subsequent classification on the basis of the duration for which the
performance of the divisional element under these conditions satisfies specified criteria.
