提出了危险货物运输用自热物质分类的测试策略。该战略是根据联合国建议书中所述的测试和使用的相关性制定的。结果表明，放热反应的活化能值对不同容器尺寸和温度下试验结果的外推有显著影响。基于Grewer烘箱试验筛选、140°C下的25mm立方体试验和特定材料的活化能的测定的组合，提出了将化学品分类为自热的流程图。所提出的方法允许更准确地预测大型容器中的化学稳定性，并且消除了在实验室中对高能化学品进行危险的大规模测试的需要。
A testing strategy for the classification of self-heating substances for transport of dangerous goods is proposed. The strategy was developed based on the tests described and correlations used in the UN Recommendations. It was demonstrated that the value of activation energy of the exothermic reaction has a significant impact on the extrapolation of test results with regard to different container sizes and temperatures. Based on a combination of the Grewer Oven test screening, the 25mm cube test at 140°C, and the determination of the activation energy of a specific material, a flowchart is presented for classifying chemicals as self-heating. The presented approach allows predicting chemical stability in large containers more accurately and eliminates the need to perform hazardous large-scale tests of energetic chemicals in a laboratory.
