Standards compliant:
GB / T 14402-2007 "Combustion properties of building materials and articles - Determination of combustion calorific value"
Building materials burning calorific value tester / building materials burning calorific value detector
Main features:
1. This equipment is in the same kind of pre-product developed on the basis of a new type of analytical instruments;
2. Using high-end single-chip, large-screen LCD screen, the entire Chinese user interface;
3. Has a high precision measurement, small size, easy operation, automatic ignition, automatic water, water, mixing, calculation, printing and other characteristics;
4. It is one of the test methods to evaluate whether the combustion performance meets Grade A composite (sandwich) materials is used to determine the total calorific value and the net calorific value.
Building material combustion calorific value calorimeterTest principle:
Under standard conditions, a specific mass of the sample is placed in a constant volume of oxygen and nitrogen calorimeter, the test sample combustion calorific value of the equipment, under standard conditions, the test to test the temperature based on the consideration of all heatLoss, and latent heat of vaporization, calculate the combustion calorific value of the sample.
