This document specifies a method for the determination of burning rate under ambient conditions for solid gun propellants. It is applicable to solid gun propellants and black powder in their original form up to a grain size of 8 mm. NOTE 1 Knowledge of burning rate is of high importance to manage risks associated with handling such explosives and of high importance to assess whether performance characteristics are met. NOTE 2 In cases where propellants having grain size higher than 8 mm are generally used, their burning rate is more influenced and controlled by parameters of element containing thereof, and thus knowledge of their burning rate at ambient condition is not of high importance.
