Several density measurements were available
from the published literature. Although none of the published densities
were measured according to guidelines, there was good agreement between
all reported values, using different techniques and performed by
independant laboratories, on independant samples. As a result, the
average of the values (n=5) was selected for risk assessment purposes.
Considering the good agreement between independent results, based on the
weight-of-evidence the available data is considered to be reliable and
adequate for classification and labelling, and risk assessment purposes
in accordance with Regulation (EC) No. 1907/2006, Annex XI, 1.2.
