What is a Calorimeter? An Overview of Calorimeters and the SBG04 by HuksefluxUSA

Calorimeters are essential tools for measuring heat-related properties of materials and substances. This article provides an introduction to calorimeters, explains their functioning, and highlights the SBG04 heat flux sensor by Hukseflux, a standard component in cone calorimeters used for reaction-to-fire tests according to ISO 5660 and ASTM E1354.

A calorimeter is an instrument used to measure the amount of heat absorbed or released during chemical reactions, physical changes, or other thermal processes. It helps scientists and engineers determine the thermal properties of materials and analyze the energy content of substances.

There are several types of calorimeters, including:

1. Adiabatic calorimeters
2. Isothermal calorimeters
3. Bomb calorimeters
4. Differential scanning calorimeters (DSC)
5. Cone calorimeters

Each type of calorimeter serves specific purposes and operates based on different principles. This article will focus on cone calorimeters and their applications in reaction-to-fire tests.

Cone calorimeters are designed to measure heat release rates, smoke production rates, and other parameters related to the combustion behavior of materials. These calorimeters are widely used in reaction-to-fire tests according to ISO 5660 and ASTM E1354 standards.

Reaction-to-fire tests are critical for assessing the fire performance of materials and products. The data obtained from these tests are used to improve fire safety and prevent the spread of fire in various applications, including transportation, construction, and consumer products.
