Stability analysis of nanomaterials according to OECD 318
Chemical testing : stability of nanomaterials according to OECD 318
Why carry out nanomaterial testing ?
At the nanometric scale, new physico-chemical properties can appear on certain materials. The analysis and study of these phenomena is therefore essential to understanding the effects of nanomaterials in their environment.
What does OECD 318 say ?
The OECD defines tests to be carried out on chemicals to determine their potential hazards in their context of use.
Test 318 in Section 3 describes a test method for obtaining data on the dispersion stability of manufactured nanomaterials in simulated environmental media.
FILAB can help you test the stability of nanomaterials according to OECD 318
What is the method described in this test ?
The test described by OECD 318 is designed to assess the ability of a nanomaterial to form and maintain a colloidal dispersion. The test method described here is dispersion by calibrated sonication, followed by particle determination in environments with different hydrochemical characteristics.
