This standard specifies the terms, definitions, symbols and abbreviations for high-efficiency and ultra-high-efficiency filter media and filter efficiency and resistance testing, selection of test methods, performance test methods for high-efficiency and ultra-high-efficiency air filters, and performance tests for high-efficiency and ultra-high-efficiency filter media. method etc. This standard applies to the detection of high-efficiency and ultra-high-efficiency filter materials used in filtering aerosols, as well as filter efficiency and resistance. Efficiency and resistance testing of sub-high-efficiency filter materials and filters can be carried out by reference.
