The gas produced per unit weight of DIPAM in the 260 C vacuum stability test is dependent upon the size of the sample used. This lack of scaling is the result, in part, of decomposition of DIPAM vapor as well as from solid DIPAM. DATB showed the same lack of scaling as DIPAM. However, TATB, HNS and NONA scale quite well. A unique pressure effect was found while investigating the thermal stability of DIPAM.
