Sweepers - Part 3: Efficiency of particulate matter collection - Testing and Evaluation
 N EN 15429-3

Annotation

This European Standard establishes a method to assess the PM10 and PM2,5 efficiency of road sweepers. PM10 and PM2,5 efficiency includes a sweeper's ability to:

— Remove and capture PM10 and PM2,5 particulate matter, and coarse size fractions, from typical urban road surfaces;

— Minimize the amount of airborne and entrained PM10 and PM2,5 particulate matter resulting from the sweeping process.

The sweeper's ability to remove and capture particulate matter and coarse size fractions is assessed using procedures and equipment to determine the amount of a test material (consisting of particulate matter and coarser size fractions) the sweeper is able to remove from a test surface during a controlled test run. This test measurement is used to calculate the removal efficiency for the sweeper.

The sweeper's ability to minimize the amount of airborne and entrained particulate matter is also assessed using procedures and equipment to determine the airborne concentrations of PM10 and PM2,5 resulting from the sweeping of a test material (consisting of particulate matter and coarser size fractions) during a controlled test run. The test measurements are used to calculate PM10 and PM2,5 emission ratings for the sweeper. This test allows the use of dust suppression water. Sweepers configured as flushing machines, or equipped with front-mounted spray bars which are not part of a dust suppression water system are not within the scope of this test.

The road sweeper's performance results are reported in a quantitative numerical format that will allow comparative assessments of similarly classified sweepers. This test does not specify pass/fail criteria for the PM10 and PM2,5 efficiency measurements specified in the test procedure.
