Any other information on results incl. tables
Considering the density of acetonitrile at 20 °C of 0,781 g/cm3, two values of the relative densities were determined such as 1,5442 and 1,5183, respectively. An average value of 1,5313 for the relative density was considered with a deviation of 0,0183.
| Weighted (g) | test 1 | test 2 |
| pycnometer + acetonitrile = m1 | 54.2135 | 54.2240 |
| sample = m2 | 4.6540 | 8.6665 |
| pycnometer + acetonitrile + sample = m3 | 56.5137 | 58.4325 |

Applicant's summary and conclusion
- Conclusions:
- The relative density of the test substance was determined to be 1,5313 at 20°C, using a volume pycnometer (in accordance with EC A.3 and OECD 109 guidelines).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
