The Heubach test method was established in 2008 to measure free-floating dust from treated seeds. In this test, treated seeds are mechanically stressed over a defined time period to measure the proportion of free floating dust in the seed lot. With the help of a continuous operating airflow free-floating dust an abrasion particles are collected in a filter. The measured amount of dust can be applied to the amount of seed inserted. In the laboratory, the JKI applies the "JKI-Heubach-Method".
