Test No. 318: Dispersion Stability of Nanomaterials in Simulated Environmental Media
This test guideline describes a test procedure to gain information on dispersion stability
of manufactured nanomaterials in simulated environmental media. The main purpose of
this guideline is to assess the ability of a nanomaterial to attain a colloidal dispersion
and to conserve this dispersion under environmentally relevant conditions. The test
procedure involves a dispersion of the nanomaterial with the aid of a calibrated sonication
procedure and the determination of the mass concentration of the nanomaterial in a
set of test vials while the particles undergo homoagglomeration and settling in environments
of different hydrochemistry
