The Heat Release apparatus measures time to ignition, mass loss and heat-release rate (option) of specimens exposed in the horizontal orientation to controlled levels of irradiance with an external igniter.
On the front panel, the following are mounted:
Load cell controller
Tare button
Temperature Controller
Control switches comprising four red on/off push-button switches, which operate by firm pressure and light up when activated:
Ignition switches on the spark-generator circuit housed in the test chamber base
Load cell switches on the Newport controller
Power switches on mains electricity to the unit
Cone switches on the Eurotherm controller. This, in turn, energises a solid state relay, which switches the power to the cone heater (5kW)
Features:
Special split shutter mechanism is designed to prevent heating of the sample before the test is started
Fire model manufactured from stainless steel for long life
Three control thermocouples for the cone heater to maintain accurate heat flux
Sample weight measurement is by a strain gauge load cell with quick electronic tare facility
Control unit contains switches for power, ignition, load cell and cone heater
Spark assembly is used in conjunction with the shutter mechanism. Microswitches are fitted to the spark arm and the shutter mechanism for safe operation
Load cell controller with a weight-ranging facility to improve performance to suit weight of sample 0-500g
Temperature controller for ramp and control of cone heater.
The Cone Calorimeter has been produced to be the most compact and easily maintained unit in the marketplace. It fits into the smallest of labs and is easy to operate using the user-friendly, menu-driven software, which guides users through the calibration, testing and reporting protocols. The name of the cone calorimeter was derived from the shape of the truncated conical heater the designer, Babrauskas, used to irradiate the test specimen (100 × 100mm) at fluxes up to 100 kW/m2 in the bench-scale oxygen-depletion calorimeter that he and his co-workers developed.
