| 英文摘要: |
| The work aims to study the accuracy of the 71 ℃ test method for extrapolating the storage life of pyrotechnics. By using a comparative analysis method, the life influencing factors of the 71 ℃ test method in the US military standard and the national military standard were analyzed. The acceleration model, experimental conditions, and extrapolated temperature values all had an impact on the life extrapolation results of pyrotechnics. In conclusion, the accuracy of the evaluation results using the 71 ℃ test method depends on whether the usage scenario is correct, whether the test conditions are set reasonably, and whether the storage environment temperature value is accurate. Suggestions for the use of the 71 ℃ test method are proposed. |
