Abstract:

Flash point determination is essential for ensuring the safe handling, storage, and transportation of combustible materials. To investigate this variability, flash point testing was conducted using a closed-cup method in accordance with ASTM D93. This standardized approach provides controlled, enclosed conditions to simulate real-world scenarios where vapor containment plays a significant role in ignition risk. The study specifically examined the impact of varying heating rates on flash point measurements, with results indicating a clear inverse relationship. As heating rates increased, flash point readings decreased significantly, with sulfur igniting at temperatures as low as 195°C under rapid heating conditions. These results emphasize the need for controlled testing environments, especially when evaluating volatile materials or those sensitive to impurities. In this regard, the closed-cup method provides this by simulating real-world enclosed environments.
