Reference
Two test series with different weights were performed at ambient temperature (22.4 °C ± 0.2 °C).
1strun: weight = 10.7605 g
1. measurement: p1 (psi) = 19.414, p2 (psi) = 11.198, volume (cm³) = 7.8798, density (g/cm³) =1.3656
2. measurement: p1 (psi) = 19.510, p2 (psi) = 11.253, volume (cm³) = 7.8820, density (g/cm³) = 1.3652
3. measurement: p1 (psi) = 19.671, p2 (psi) = 11.347, volume (cm³) = 7.8753, density (g/cm³) = 1.3664
Mean volume = 7.8790
Mean density = 1.3657
2ndrun: weight = 10.2395
1. measurement: p1 (psi) = 19.400, p2 (psi) = 11.234, volume (cm³) = 7.6133, density (g/cm³) = 1.3449
2. measurement: p1 (psi) = 19.584, p2 (psi) = 11.343, volume (cm³) = 7.5986, density (g/cm³) = 1.3476
3. measurement: p1 (psi) = 19.474, p2 (psi) = 11.284, volume (cm³) = 7.5700, density (g/cm³) = 1.3526
Mean volume = 7.5940
Mean density = 1.3484
Mean density for the two test series: 1.3571 g/cm³
Relative density (compared to water at 4 °C, 1.000 g/cm³): 1.357
Description of key information
Relative density at 22.4 °C (compared to water at 4 °C) = 1.36 (OECD Guideline 109, air comparison pycnometer method).
Key value for chemical safety assessment
Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
