BS ISO 21843:2018

This standard BS ISO 21843:2018 Determination of the resistance to hydrocarbon pool fires of fire protection materials and systems for pressure vessels is classified in these ICS categories:

• 13.220.50 Fire-resistance of building materials and elements

This document specifies a test method for determining the fire resistance of pressure vessels with a fire protection system when subjected to standard fire exposure conditions. It does not address vessels cooled by water deluge or water monitor. The test data thus obtained permits subsequent classification on the basis of the duration for which the performance of the pressure vessel under these conditions satisfies specified criteria. The design of the pressure vessel is not covered in this document.
