EN ISO 1716 Reaction to Fire Tests for Products - Determination of Gross Heat of Combustion (Heat Value) Test

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 1716 testing. This standard specifies a method for determining the gross heat of combustion (QPCS) of fixed volume products in a bomb calorimeter. This method is intended to be applied to solid products.

In this test, a test sample of a given mass is burned in a calibrated bomb calorimeter by burning certified benzoic acid under standardized conditions, at a constant volume, in an oxygen atmosphere. The heat of combustion determined under these conditions is calculated on the basis of the observed temperature rise, taking into account the heat loss and the latent heat of evaporation of water.

This is a test method for determining the absolute value of the heat of combustion for a product and does not take into account any variability in the structure of the product.

The mixer must be driven by a constant speed motor. To prevent heat transfer to and from the calorimeter, the drive shaft of the agitator shall have a heat-insulated section in a gasket between the jacket cover and the jacket. A magnetic stirrer with similar performance is an acceptable alternative.

For an adiabatic calorimeter system, a heater and thermometer system must be included in the vessel such that the water temperature in the jacket is kept at the same temperature as the water in the calorimetric vessel.
