I. Applicable standards:
ASTM E648-15 Standard Test for Critical Radiant Flux of Floor Coating Systems Using Radiant Heat Energy sources
BS EN ISO 9239-1-2010 "Reaction to fire tests on floor coverings - Determination of combustion performance using a radiant heat source"
GB/T 11785-2005 -- Determination of the Combustion Properties of Paving Materials -- Radiant Heat Source Method
Ii. Product Overview of the floor material combustion performance tester:
The test machine measures all kinds of paving materials, such as textile carpet, cork board, wood board, rubber board and plastic floor and floor spray material.
The results can reflect the combustion performance of the paving material (including the substrate). The test method is to assess the flame propagation capability of the paving material horizontally placed and exposed to the tilted thermal radiation field by small flame ignition in the test combustion chamber.
Three, the floor material combustion performance testing machine product characteristics
1, the main components are imported, safe and reliable, long service life;
2. The gas pipeline is reasonably arranged and equipped with gas leakage and tempering device. In case of gas leakage, the gas at the inlet will be automatically shut off and an alarm will be given.
3. Radiant panel temperature can be automatically adjusted, propane gas supply is equipped with imported mass flow controller, air output measurement is equipped with an independent blower, frequency conversion is automatically adjusted, without manual labor;
4. During normal test, the flame spread distance can be recorded by foot switch without manually clicking the mouse to operate the computer;
5. Adopt industrial all-in-one machine, convenient and reliable operation;
6. Adopt the advanced measurement and control software independently developed in VB language to centrally control the collection, processing and analysis of data;
