√ 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 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 IMO, SOLAS) is primarily undertaken in accordance with classification society procedures through testing to the 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 MSC 307(88) where relevant, allowing testing to both IMO and ISO test procedures for specific classification ratings.

√ Scope
This document specifies a test procedure for determining the fire resistance of divisional elements with a fire protection system, when exposed to cellulosic or hydrocarbon-pool type fire conditions. It is applicable to divisional elements intended for non-marine applications but suitable for offshore fixed and mobile installations.
The test data obtained, when used in conjunction with published fire test standards, permit subsequent classification of the divisional elements based on the duration of their performance against specified criteria.

√ Terms and definitions
For the purposes of this document, the terms and definitions in ISO 13943 and the following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

◆bulkhead
vertical divisional element typically used in the marine industry

◆deck
horizontal divisional element typically used in the marine industry

◆divisional element
element that is intended for use in maintaining separation between two adjacent areas of facilities within the oil and gas industry, and which may or may not be load bearing

◆critical temperature
temperature at which the yield strength of the material is reduced to the minimum allowable under operating loading conditions

◆structural core
primary component or components of the divisional element responsible for providing load bearing capability or integrity (as appropriate), excluding additional components provided for insulation purposes
Note 1 to entry: This typically consists of a metallic plate (either flat or corrugated) with stiffeners.
