Abstract
The focus of this paper is the interpretation and application of the Multipass Filter test- more commonly known as the Beta test for determining a filters (or medias) Beta Rating.
A specific Beta test report is deserved and analyzed. A review of the required test equipment for conducting a Multipass test is provided and many test operating conditions are described. The Beta Rating definition and detailed points for conducting a Beta test are also given.
