摘要:总结了国内口罩的类型、标准及适用范围,对部分标准中颗粒物过滤效率的指标要求进行了对比,分析了
各标准中颗粒物过滤效率检测的条件和检测方法,对比了文献报道的3 种校准方法。目前我国还没有口罩颗粒物过
滤效率测试仪计量检定规程或仪器校准规范,在全国范围内也没有量值统一或溯源的方法,必将影响口罩过滤效率
测量结果的准确性,最终影响口罩质量。
Abstract:The types, standards and application scope of domestic masks were summarized, and the index
requirements of particulate matter filtration efficiency in some standards were compared, analyzes the detection conditions
and methods of particulate matter filtration efficiency in various standards, and compares three calibration methods reported
in the literature. At present, there was no national metrological verification regulation or calibration specification for the
mask particulate matter filtration efficiency tester in China, and there was no method to unify the measurement value or
trace the source in the whole country, which would affect the accuracy of the measurement results of the filter efficiency of
the mask, and ultimately affect the quality of the mask.
