Information about Room Corner Test

Fire testing – Surface layer – Large Scale Room fire test. The method is a so-called reference scenario for surface linings to Euroclass A-E. It is also used in marine application for classification of “fire-restricting materials” intended for High-Speed Craft, FTP Code 2010 (Resolution MSC.307(88)), Part 10, annex 1.

The method evaluates the fire characteristics of a surface product in a room fire scenario. The field of application is for building products that, for some reason, cannot be tested in small scale, for example thermoplastic materials, joint systems and materials with large irregularity. Other products can also be evaluated in the method, for example pipe insulation and upholstered furniture.

Methods used: ISO 9705, EN 14390, FTP Code 2010 (Resolution MSC.307(88)), Part 10, annex 1.

The method measures the following: heat release rate (kW), total heat release (MJ) and smoke production rate (m2/s). The flashover phenomenon, flame spread and burning droplets or particles visually is also registered. When necessary, toxic gases can also be measured using FTIR analysis.

The method is also used for research purpose and for fire modelling studies.

Examples of products that can be tested with this method

Building products, mostly surface linings, composite panels etc.

Material consumption during test

Complete test At least 35 m2, with dimensions that facilitate mounting in the room described below (see figure)

Test procedure 

During test, the test sample is mounted on the inside of the room, in the ceiling and on all the walls except for the wall with the door opening. A propane gas burner is located in one of the corners and produces a heat release rate of 100 kW during 10 minutes, and then 300 kW the following 10 minutes. The total test time is 20 minutes. The combustion gases are collected through a hood where heat release rate and smoke production are measured. Flame spread along walls and ceiling are observed visually. If flames emerge from the door opening, flashover has occurred and the test is terminated. The heat release rate at flashover is generally about 1 MW. See figure below.
