s: standard deviation
t: value t-table: 4.303 (two sided, P: 95 % (f = N-1))
N: number of measurements
P: probability
f: degree of freedom
Average relative density D420: 0.9616 ± 0.00042 * 4.303 / √3
Average relative density D420: 0.9616 ± 0.00105 (N = 3, P: 95 %)
Description of key information
Relative density at 20 °C (compared to water at 4 °C) = 0.9616 ± 0.00105 (OECD Guideline 109, pycnometer method)
Key value for chemical safety assessment
- Relative density at 20C:
- 0.962
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.
