Reference
Table 1 shows the determined volume of the pycnometer. The results of the test for the determination of the density of the test item are given in Table 2.
The individual measurements were obtained with a deviation of ≤ 0.01 g/cm3. According to the guideline, the density of the test item is given as the mean value.

Conclusion
A pycnometer was used for the determination of the density and relative density of N-ethylcaprolactam.
The density of the test item at 20°C was 0.987 g/cm3 (0.987 × 103 kg/m3).
The relative density was 0.987.
Description of key information
0.987 at 20 °C (pycnometer method, OECD 109)
Key value for chemical safety assessment
- Relative density at 20C:
- 0.987
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).
