ASTM F1471-09

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

Scope

  • 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.
