時間-壓力測試器

TPT 系列™（時間-壓力測試器）用於根據《聯合國危險貨物運輸建議書》對危險物質（易燃、氧化和高能量物質）進行危險性分類。測試方法是在半封閉容器中點燃被測物質，並測量由此產生的壓力-時間曲線。

應用

確定封閉條件下的燃燒特性（從點燃到爆燃轉變的趨勢及其劇烈程度）是化學和炸藥行業在生產、處理和運輸過程中對高能量化學品進行危險評估的一個重要參數。透過標準化測試獲得的結果（最大壓力和壓力上升時間等）可提供有關暴力分解的安全資訊。比能量 ( 能耗 ) 決定了被測物質所釋放的機械能的大小。

TPT-SW3 軟體中的測量視窗	TPT-SW3 軟體中氧化性液體測試的評估程序( 圖表 )

The TPT Series™ (Time-Pressure Test Apparatus) is used for the hazard classification of dangerous substances (flammable, oxidizing and energetic materials) according to the UN Recommendations on the Transport of Dangerous Goods. The test is based on ignition of a tested substance in a semi-closed vessel and measurement of the resulting pressure-time profile.

APPLICATIONS

Determination of the burning characteristics (tendency to ignition-to-deflagration transition and its violence) under confinement is an important parameter for hazard assessment of energetic chemicals in production, handling and transportation in chemical and explosives industries. Results obtained by standardized tests (max. pressure and pressure rise time etc.) provide safety information about violence of decomposition. Specific energy determines the amount of mechanical energy released by tested substances.
