Fire Testing Equipment Building Materials Heat Release Rate Test Machine ISO5660-1

1, Equipment standard:

ISO5660-1:2015 Test Method for Heat Release Rate of Building Materials.

2, Scope of use:

The oxygen consumption calculated from the oxygen concentration in the gas stream of combustion products and the heat release rate of combustion products. The heat release rate of materials is also the most important parameter in the combustion performance of materials. Accurate measurement of the heat release rate of materials in the combustion process is extremely important for the prediction of fire hazards and fire retardant prevention treatment.

3, Operating conditions:

Heat Release Rate test mainly evaluates the following test items:

1. Flammability;
2. Flame propagation;
3. Smoke production;
4. Smoke toxicity;

ISO 5660-1 Sample Requirements:

The surface of the sample must be flat, and the sample must represent the actual product, preferably similar to the final product. A complete test requires 12 samples.
