FOREWORD
Due to the frequent practice of prefiltering, filters are often used in two-stage systems. Because the first filter removes some of the particles from the airstream, the downstream filter sees fewer large particles and a greater percentage of smaller particles. This results in a different performance for the downstream (final) filter than would be expected based on loading with the same dust as the prefilter. Thus, an optional test method has been developed to allow standard testing for two-stage systems.
Note: In this addendum, changes to the current standard are indicated in the text by underlining (for additions) and (for deletions) unless the instructions specifically mention some other means of indicating the changes.
