The determination standards of explosion index at home and abroad are compared and analyzed from the aspects of determination principle, test device, test concentration, result expression and safety requirements. The requirements of test devices in domestic and foreign standards are the key parts of comparative analysis. It is found that there are significant differences in the flexibility, test principle, result expression and safety requirements of test devices between domestic and foreign standards. The domestic standard needs to be improved in terms of the flexibility of the test device, and it is necessary to refer to the relevant research and standards to formulate more strict and clear regulations. The domestic standard should consider turning to absolute pressure to improve the accuracy and reliability of the test.

从测定原理、测试装置、测试浓度、结果表达以及安全要求等方面对比分析国内外爆炸指数的测定标准,国内外标准中对测试装置的要求是重点对比分析的部分。研究发现,当前国内外标准在测试装置的灵活性、测试原理和结果表达以及安全要求方面存在显著差异。国内标准在测试装置的灵活性方面有待提升,需要参考有关研究和标准,制定更加严格和明确的规定;应考虑转向使用绝对压力以提高试验的准确性和可靠性。
