Wood board ISO 5660-1 heat release rate mapping test

ISO 5660-1 Standard name ：

ISO5660-1 Reaction to fire test — Heat release 、 Smoke production and mass loss rate - The first 1 part : Heat release rate

ISO5660-1 Reaction to fire tests-Heat release, smoke production and mass loss rate-Part 1: Heat release rate (cone calorimeter method)

Sample specification ：

Sample specification ：100 mm x 100 mm , The sample thickness is less than 50mm. The actual thickness of the specimen is less than 6mm The actual substrate used in the sample shall be taken with the sample during the test so that its overall thickness is not less than 6mm.

The face of the sample must be flat , And the sample must be representative of the actual product , It is better to be similar to the final product , Complete testing requires 12 A sample , Bottom test 2pcs sample .

Testing process ：

Mount the specimen horizontally under the radiation cone with a specific radiation flux , Insert spark plugs , Ignite the igniter .

In the following cases , Stop data collection ：

a) Keep burning 32min

b) Sample at 30min Not ignited inside

c) The sample mass becomes zero

d)XO2 Return to the pre test oxygen concentration 0.01% Within the scope of , continued 10min

The radiation flux is 25kW/m2 and 50kW/m2, The radiation flux needs to be confirmed before the test .

Test range ：

This standard specifies the use of external igniters , When the specimen is subjected to a controllable level of thermal radiation in the horizontal position , Method for determining heat release rate . The measurement of heat release rate is determined by the oxygen consumption calculated from the oxygen concentration in the gas stream of combustion products and the flow rate of combustion products , It also ignites the sample ( Continuous flaming combustion ) Time was measured .
