SN/T 3078.1-2012 (English Version) PDF

Scope: This part of SN/T 3078 specifies recommended operating procedures for acceleration calorimeters. This calorimeter can obtain data on the temperature and pressure changes with time when the system undergoes physical and chemical changes under approximately adiabatic conditions. This section applies to the evaluation of thermal stability of chemicals using the accelerated calorimeter method. When appropriately scaled, data from tests in this section can be used with caution to predict hazards associated with the processing, storage, and transportation of chemicals or chemical mixtures. Under appropriate conditions, this standard is suitable for studying the effects of catalysts, polymerization inhibitors, initiators, reaction atmosphere, material structure or stirring.
