Points to Know for Process Safety Testing - Sigma HSE
1. Thermal Stability GAS &VAPOUR TESTING The thermal stability of all materials exposed to elevated temperatures must be known to ensure safe handling conditions. This includes raw materials, intermediates (including reaction mixtures) and final products The range of tests include: - Air over layer - A test in which pre-heated air is circulated over the sample during a temperature ramped or isothermal test. This test specifically simulates the tops of spray dryers, flash dryers or conditions where thin layers exist Bulk Powder(diffusion Cell) - The bulk powder diffusion cell test is conducted to establish the onset temperature of exothermic activity of a material when exposed to elevated atmospheric temperatures. Aerated Cell - A test in which air is forced through the sample during a temperature ramped or isothermal test. This test simulates fluid bed drying and tumble type dryers 2. ELECTROSTATIC TESTING Static electricity is ubiquitous an
