微燃燒量熱儀

ASTM D 7309

微型燃燒量熱儀是由聯邦航空局(FAA)開發的,旨在為工業界提供一種研究工具,以協助FAA大幅提高飛機材料的防火安全性。

由於該測試儀能夠獲得有意義的測試數據,並且樣品大小在0.5 Mg至50 mg之間,因此它正在成為研究實驗室的主流。該儀器已通過國家共識組織ASTM International的驗證,現已成為ASTM標准出版物D7309的主題。微型燃燒量熱法(MCC),有時也稱為熱解-燃燒流動量熱法(PCFC),用於測量在惰性氣流中受控的熱解過程中,固體釋放出燃料氣體燃燒熱的速率。將燃料氣體與過量的氧氣混合併在高溫下燃燒(氧化),並透過耗氧量熱法測量流動氣流的瞬時燃燒熱。

規格及特點
新的可燃性測試方法可以快速,輕鬆地測量塑料,木材和紡織品等的可燃性。只需要幾毫克的樣品,幾分鐘即可獲得結果,而無需花費數小時或數天的時間。 上面顯示的測試設備提供了大量有關材料著火危險的信息。

Micro Combustion Calorimeter

ASTM D 7309

The Micro Combustion Calorimeter was developed by the Federal Aviation Administration (FAA) to offer industry a research tool to assist the FAA in its mandate to  dramatically improve the fire safety of aircraft materials.

The tester is becoming a mainstay in research laboratories due to its ability to obtain meaningful test data with a sample size in the range of 0.5 Mg to 50 mg.  The instrument has been validated by a national consensus organisation ASTM International and is now the subject of an ASTM standards publication, designated D7309.  Micro Combustion Calorimetry (MCC), sometimes referred to as Pyrolysis-Combustion Flow Calorimetry (PCFC), measures the rate at which the heat of combustion of fuel gases are released by a solid during controlled pyrolysis in an inert gas stream. The fuel gases are mixed with excess oxygen and combusted (oxidised) at high temperature, and the instantaneous heat of combustion of the flowing gas stream is measured by oxygen consumption calorimetry.

Specification and Features
The new flammability test method quickly and easily measures the combustibility of plastics, wood and textiles etc. Only a few milligrams of sample are needed and results are obtained in minutes, instead of hours or days of analysis. The test apparatus shown above, provides a wealth of information on the fire hazard of a material. View the downloadable data sheet for more information.
