- Results:
- The results showed that boron oxide (ETI; d50 mm 0.44) did not produce significant amounts of dust and was nearly dust free. Diboron trioxide (boric oxide 200 mesh; d50 mm 0.044) did produce a significant amount of dust and was classified as dusty.
- Conclusions:
- Boron oxide (ETI; d50 mm 0.44) did not produce significant amounts of dust and was nearly dust free. Diboron trioxide (boric oxide 200 mesh; d50 mm 0.044) did produce a significant amount of dust and was classified as dusty.
- Executive summary:
The dustiness of two samples of the test item were assessed in a GLP study according to CIPAC method MT 171. The sample with a d50 of 0.44 mm did not produce significant amounts of dust and was nearly dust free, the sample with a d50 of 0.044 mm did produce a significant amount of dust and was classified as dusty.

Description of key information
Dustiness:
Studies on dustiness were performed according to CIPAC method MT 171 according to GLP and showed that diboron trioxide (boric oxide 60 mesh with a d50 of 0.051 mm) and boron oxide (ETI, d50 = 0.44 mm) were dust category 1 - nearly dust free and diboron trioxide (Boric oxide 200 mesh with a d50 of 0.044 mm) was dust category 3 – dusty. The dustiness is related to the particle size.
