Initially, 35 cm3 of sample is used. The discharged particles are collected using three particle size-selective metal foams and an absolute filter. The first two metal foams are identical. The duplication is normatively anchored and serves the purpose of manageability. Within this standard, the following table can be found for classifying the obtained results.
| Classes: | very low | low | moderate | high |
| Dustiness of inhalable dust, wI,A mg kg-1 | < 300 | 300 to 650 | > 650 to 3000 | > 3000 |
| Dustiness of thoracic dust, wT,A mg kg-1 | < 80 | 80 to 300 | > 300 to 1000 | > 1000 |
| Dustiness of respirable dust, wR,A mg kg-1 | < 10 | 10 to 60 | > 60 to 210 | > 210 |
