ISO 9705 Surface Products Full Scale Room Corner Test Heat Release
Rate Fire Testing Equipment
Description:
Room Corner Test to perform fire reaction tests from Ineltec
simulates a fire in a well-ventilated conditions started in a
corner of a small room with one door open according to the standard
ISO 9705:1993.
It is intended to evaluate the contribution to fire growth provided
by a product surface using a specified ignition source.
The Room Corner Test ISO 9705 is particularly suitable for products
that for some reason can not be tested in a small laboratory scale.
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.
Standards:
ISO 9705: 1993 Fire Tests
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.

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.
