Description of the Test
Standard Test Method for Air Cleaning Performance of a High-Efficiency Particulate Air- Filter System
Products that can be tested
High-efficiency particulate air (HEPA) filter systems
- This test method covers the procedure and equipment for measuring the penetration of test particles through high-efficiency particulate air (HEPA) filter systems using a laser aerosol spectrometer (LAS). This test method provides the capability of evaluating the overall effectiveness of HEPA filter systems consisting of one or two filter stages.
- The aerosols used for testing have a heterodisperse size distribution in the submicrometer diameter range from 0.1 to 1.0 μm.
- The purpose for conducting in-place filter testing by this test method is in the ability to determine penetration of multi-stage installations.
- This test method provides a comparative indication of the capability and essential performance characteristics of high-efficiency particulate air (HEPA) filter systems.
