Scope

Scope: This document establishes a test procedure for measuring the thermal stability of materials using a differential scanning calorimeter, a rapid screening calorimeter, and an adiabatic calorimeter in combination. It specifies the operational steps for obtaining material stability parameters and quickly determining whether the material exhibits exothermic behavior. This document is applicable to the thermal stability testing and thermodynamic research of various materials involved in chemical reaction processes, including raw materials, intermediates, products, by-products, and waste products, as well as materials involved in separation processes such as distillation and fractionation. Main technical content: Basic process for using five calorimeters in combination 5.1 Use a differential scanning calorimeter to conduct thermal stability tests on milligram-level materials. 5.2 Use a rapid screening calorimeter to conduct thermal stability tests on gram-level materials. 5.3 Determine whether the material exhibits exothermic behavior based on the test results from 5.1 and 5.2 and the following principles: a) If both the differential scanning calorimeter and the rapid screening calorimeter detect exothermic behavior, determine that the material exhibits exothermic behavior and proceed to the adiabatic calorimeter test. b) If the differential scanning calorimeter does not detect exothermic behavior but the rapid screening calorimeter does, determine that the material exhibits exothermic behavior and proceed to the adiabatic calorimeter test. c) If the differential scanning calorimeter detects exothermic behavior but the rapid screening calorimeter does not, determine that the material exhibits exothermic behavior and proceed to the adiabatic calorimeter test. d) If neither the differential scanning calorimeter nor the rapid screening calorimeter detect exothermic behavior, determine that the material does not exhibit exothermic behavior and end the test. 5.4 Use an
