輻射地面面板設備

 

EN ISO 9239-1

 

EN ISO 9239-1輻射地板面板測試是地板材料對Euroclass系統中的防火測試做出反應的基石，該測試使用輻射熱點火源在熱暴露下測量樣品火焰的擴散。暴露是指起源房間內發生的火災，該火災通過門的開口輻射到相鄰房間或走廊的地板上，與將地板材料分類為A2FL，BFL，CFL和DFL類別有關符合BS EN 13501-1 2007 + A1 2009中的要求.EN ISO 9239-1適用於地板，該設備還可用於根據標準ASTM E648和DIN 4102;第14部分進行測試。

 

測試室由覆蓋有拋光不銹鋼面板的支撐框架組成，測試室用矽酸鈣絕緣板絕緣，並設有耐溫觀察窗。不銹鋼樣品支架組件安裝在滑動平台上，以允許安全輕鬆地加載測試樣品。

 

控制系統調節流量以確保恆定的空氣混合氣，這對於在測試過程中保持恆定的熱通量曲線非常重要。陶瓷多孔輻射板配有​​質量流量儀表，可對氣體和空氣供應進行微調。安全儀表也包括在內。

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.
