Large Furniture Calorimeter

Large Furniture Calorimeter

   Introduction:   

Furniture large calorimeter is based on GB / T 20286-2006 requirements in Appendix B and C of R & D production; the device can measure exposure to an open flame ignition source under the upholstered furniture and furniture components and combustion performance tests. The device meets GA111-1995, "Standard Test Method for Surface entity room fire products" GB / T 27904-2011 and GB / T 25207-2010 part of the requirements of the test (Note: The entity room part is optional).

Furniture large calorimeter consists of an ignition source, conical collector, exhaust pipes, fans, weighing station and measuring device component; test system comprising: a gas collection and analysis system; gas control system; weighing measuring system; smoke density test system.

Pipeline built-in temperature sensors, gas flow meters, gas sampling probe and a multi-stage filter sampling line analytical instruments to ensure long life.

Software control system under Windows can automatically collect and perform complex data analysis and recording. The software can automatically calculate the heat release rate, mass loss rate and smoke density and other relevant parameters, and gives detailed product test reports. Equipment while providing data printing interface.
