EC number: 215-125-8
CAS number: 1303-86-2
of dust collected
(boric oxide 60 mesh)
Nearly dust free
The dustiness of the sample was assessed in
a GLP study according to CIPAC method MT 171. The sample with a d50 of
0.051 mm did not produce significant amounts of dust and was nearly dust
Boron oxide (ETI)
Diboron trioxide (Boric oxide 200 mesh)
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.
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.
