ASTM E1231-19 + Redline

Standard Practice for Calculation of Hazard Potential Figures of Merit for Thermally Unstable Materials

1.1 ,This practice covers the calculation of hazard potential figures of merit for exothermic reactions, including:

(1) ,Time-to-thermal-runaway,

(2) ,Time-to-maximum-rate,

(3) ,Critical half thickness,

(4) ,Critical temperature,

(5) ,Adiabatic decomposition temperature rise,

(6) ,Explosion potential,

(7) ,Shock sensitivity,

(8) ,Instantaneous power density, and

(9) ,National Fire Protection Association (NFPA) instability rating.
