ISO- 5660-1

Reaction-To-Fire Tests - Heat Release, Smoke Production And Mass Loss Rate


Si-Quat Fire testing according to ISO 5660-1

ISO 5660-1 – Reaction-to-fire tests - Heat release, smoke production and mass loss rate 

The reason this test is important for the Si-Quat active coating is to make sure our coatings do not negatively influence the surfaces on which they are applied. 

Heat release rate (Cone calorimeter method) and smoke production rate (dynamic measurement) 

If a fire would happen smoke would limit the visibility of people in a space. By making sure our coatings do not release a denser smoke we help increase our si-quat customers safety.


The test method is used for fire technical modelling. The data from the test results can be used for modelling bigger fires and can be part of a larger certification for construction, aviation or public transportation.



When testing a product according to ISO 5660, a sample with the dimension 100 mm x 100 mm is used for the test. The surface of the sample is heated and starts to emit gases that ignite by a spark igniter. 

The emitted gases are collected in a hood and transported away through a ventilation system. 

The heat release is measured using the data on measured oxygen concentration in the emitted smoke. The smoke production is measured continually throughout the test with a laser system.
