ISO 29463-2:2011, titled "High-efficiency filters and filter media for removing particles in air — Part 2: Aerosol production, measuring equipment and particle-counting statistics," specifies the aerosol production and measuring equipment used for testing high-efficiency filters and filter media. It also outlines the statistical basis for particle counting with a small number of counted events. This standard is intended to be used in conjunction with other parts of the ISO 29463 series, which collectively address classification, performance, testing, and marking of high-efficiency filters and filter media
