Standard Test Method for Determining the Initial Efficiency of Materials to Penetration by Particulates Using Latex Spheres

Importancia y uso:

5.1 This test method measures the initial filtration efficiency of materials by sampling representative volumes of the upstream and downstream latex aerosol concentrations in a controlled airflow chamber.

5.2 This test method provides specific test techniques for both manufacturers and users to evaluate materials when exposed to aerosol particle sizes between 0.1 and 5.0 μm.

5.2.1 This test method establishes a basis of efficiency comparison between materials.
