摘要:: 简要介绍了自吸过滤式呼吸防护用品的种类和全面罩的基本结构。重点描述了日本社团法人产业安全技术协会和我国国家标准中规定的自吸过滤式全面罩呼吸阻力的检测原理、检测程序和检测方式，用两种检测方式分别对DR165L4N型全面罩和X-Plore 5500全面罩的呼吸阻力进行测试，对测试结果进行比较，通过分析与讨论，建议检测自吸过滤式全面罩呼吸阻力时，应采用将全面罩的外面罩和内面罩拆开分别测试的方式，阻力值加和，进而得出贴近自吸过滤式全面罩在实际使用时呼气和吸气阻力的值。

Abstract:: The type of the nonpowered airpurifying protective respirators and the basic structure of full facepiece are introduces in this paper. It’s mainly describes the testing principle and testing method of breathing resistance test in Japanese Technology Institution of Industrial Safety(TIIS)and the national standards. The breathing resistance test are tested with Japan and the national standard to DR165L4N and XPlore 5500.Through the comparison test results, analysis and discussion, we should take full facepiece in the mask and mask apart to test and add the two part of the resistance value.
