The slow cook-off(SCO)test is one of the important items of ammunition safety assessment. In order to ensure the rationality of the safety assessment standard formulation and revision of the missile and its propulsion system and improve the effectiveness of the SCO test, we need to learn the mature technology and standards of the SCO test from developed countries and deeply analyze the revision principles of the SCO test standard. This paper analyzes the formulation and revision process of standardization agreement(STANAG) 4382 developed by NATO countries. The munitions design finalization and arms procurement are supported. The development of IM technology is promoted. The overall improvement of military survivability and combat effectiveness are realized through implementing the standard in 1996. However, during the implementation of the standard, some doubts on the provisions have been raised by NATO members, such as heating rate, precondition and acceptance. Re-evaluating the rationality and revising the standard according to the evaluation results are required. The formulation process and key parameters of the first edition,and the revision contents and basis of the second edition are reviewed. The implementations of the standard in NATO members are collected, and the revision suggestions from the members are summarized. Through analyzing the simulation results of various heating rates and various typical environments, some suggestions on the setting of heating rates and precondition parameters in the standard are put forward, which can provide reference for the establishment of the SCO test standard in China.
