Self-Accelerating Decomposition Temperature (SADT) the lowest ambient temperature at which a runaway decomposition is observed within seven days the test is run with unstable substances, such as a peroxide, in its commercial shipping container, and the reported result applies only for the container used. 

The decomposition of some materials into smaller, more stable molecules can be initiated by mechanical shock alone, and they are known as shock-sensitive. Many commercially important chemicals are thermally sensitive and decompose with the addition of heat. For storage situations, the critical temperature at which the thermal energy is sufficient to start an uncontrolled reaction in a particular storage configuration for a specified time is known as the self-accelerating decomposition temperature (SADT), as described in NFPA 49. 

The fact that organizational values and norms are not simply a set of rules and procedures is shown by introducing the espoused theory and the theory-in-use and this has to be taken into account in the remainder of this thesis. A possible graphical representation to take organizational values and norms into account is given in Figure 17, which is derived from SADT (Structured Analysis and Design Techniques), SofTech (SofTech, 1976).

SADTs, a measure of safe storage and drying temperatures for industrial products, are determined by a variety of techniques, often large scale with up to 200 kg samples. Smaller scale calorimetric methods are discussed.
