Floor Material Thermal Radiation Plate Tester

Floor Material Thermal Radiation Plate Tester

Flooring radiant panel test apparatus

model: FRP

Floor Material Thermal Radiation Plate TesterPurpose:

Used for various flooring materials, such as textile carpetsCork board, wooden board, rubber board, plastic flooring, and floor spraying materials, etc,Measure through certain thermal radiation and flame environmentMaterial ScienceThe critical thermal radiation value under combustion conditions.

The EU uses this testing method to classify the fire rating of flooring materials in all EU member states.

Floor Material Thermal Radiation Plate TesterCompliant with standards:

GB/T11785Determination of combustion performance of flooring materials - Radiant heat source method

EN ISO9239-1Combustion performance of flooring materials - Part 1: Determination of combustion performance using a radiant heat source

EN ISO9239-2Burning performance of flooring materials Part 2::Measurement of flame spread test under thermal radiation of 25k W/m

ASTM E648Critical thermal radiation test of ground materials

ASTM E970Critical Radiation Flux Test of Roof Insulation Materials

NFPA 253Testing of critical thermal radiation flux for floor covering systems, etc

Floor Material Thermal Radiation Plate TesterProduct Technical Specifications:

1The stainless steel test box adopts a front opening design, which is easy to clean and replace the sample device

2The inner wall of the box is made of calcium silicate board, which is heat-resistant and corrosion-resistant

3Equipped with 300mm × 450mm porous ceramic heat radiation plate, placed at a 30 degree angle

4Provide T-shaped porous burner and apply open flame to the sample

5The optical system includes a 2900 ± 100 K color temperature incandescent lamp as the light source, a silicon photovoltaic cell as the light source, and a shutter for optical path testing, which is convenient for 0% and 100% calibration use

6Testing software: Smoke density DAQ testing software, which can display experimental related information such as heat radiation flux values, smoke density curves, transmittance curves, etc

7Gas control part: Use a needle valve to adjust the flame height of the T-shaped burner, a propane mass flow meter to adjust the gas flow rate of the radiation plate, digital display, a frequency converter to adjust the proportion of the mixed gas, equipped with a tempering valve to ensure no tempering during testing, and a built-in blower to provide air source. The gas used for testing is mixed through a Venturi mixture

8Medtherm water-cooled heat flow meter from the United States, with a working range of 0-50 kW/m2, heat flow meter accuracy<± 2%, response time of 0.2 s, provides a portable cooling water source, and does not require external water

Floor Material Thermal Radiation Plate TesterTechnical advantages:

1Using a blower device to provide an air source for the radiation plate, abandoning the previous practice of using an air compressor, as the air source of the air compressor is intermittent and cannot effectively ensure its continuity of supply;

2Using the MEDTHERM water-cooled heat flow meter from the United States and providing an automatic circulating cooling water source, there is no need for users to connect external cooling water;

3When calibrating the calibration plate, it can be ensured that all calibration holes meet the testing standard requirements, changing the previous situation where the remote thermal radiation flux value cannot meet the requirements;

4The optical path calibration has added an automatic shutter switch, eliminating the need to turn off the light source. Compared to similar machines at home and abroad, this is *, while better ensuring the stability and accuracy of test results.
