Radiant Flooring Panel Apparatus

EN ISO 9239-1

The EN ISO 9239-1 Radiant Flooring Panel test is the cornerstone of the flooring materials reaction to fire tests in the Euroclass system.  The test measures the spread of flame of the sample, under thermal exposure, using a radiant heat ignition source.  The thermal exposure is that of a fire growing in the room of origin that through a door opening, radiates onto the floorings in an adjacent room or corridor.  It is relevant to classification of the flooring material into classes A2FL, BFL, CFL and DFL as set out in BS EN 13501-1 2007 + A1 2009. EN ISO 9239-1 applies to floorings. The apparatus can also be used for tests to standards ASTM E648 and DIN 4102; Part 14.

The test chamber consists of a support frame covered with polished stainless steel panels. The resulting test chamber is insulated with calcium silicate insulation board and is provided with a temperature resistant observation window. The stainless steel sample support assembly is mounted on a sliding platform to allow safe and easy loading of the test sample.

A ceramic porous radiant panel complete with mass flow instrumentation with fine adjustment for the gas and air supplies. The control system regulates the flow rates to ensure a constant air gas mixture, which is very important in achieving a constant heat flux profile during the test. Safety instrumentation is also included.

Electrical: 120V AC 60Hz / 230V AC50Hz– 25A

Dimensions: 2400mm (W) x 2300mm x (H) x 700mm (D)

Weight of equipment: 400 kg

Ambient Temperature: Operating 10°C to 35°C

Gas Supplies: The preferred fuel gas used in the test is a mixture of air & propane

Propane: The flow needs to be capable of delivering 1kg/hour at a minimum pressure of 3 Bar with a minimum purity of 95%

Clean & Dry Air: The flow needs to be capable of delivering 350nl/min at a nominal pressure of 7 Bar. This is required to obtain flame stability for testing

Water supply with drain or re-circulation system to cool the heat flux meter (1l/min)

Suitable exhaust system, de-coupled from the exhaust stack, whose air velocity should be 2.5+0.2m/s within the stack with the panel turned off, dummy specimen in place and access door closed. An axial flow fan with a variable extraction rate up to a maximum of 2500 m3/h  is suitable
