- Type:
- density
- Density:
- 1.058 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The density of PU-2021-971 at 20 °C was determined to be 1.0576 g/cm3 corresponding to
1057.6 kg/m3.
The relative density liquid of the test item was calculated to be 1.0576.
Reference
Determination of the Reference Item
The reference study (study ID 72103IRS / CPD70096) was carried out with n-heptane at 20 °C. The density of the reference item was determined to be 0.6838 g/cm3, corresponding to a relative density of 0.6839
Temperature Control
During the equilibration time the temperature was kept constant at 20.0 +- 0.1 °C, for temperatures at moments of weighing (TP) see Table 1 in Overall Remarks attachement
Validity Criteria
The temperatures at moments of weighing must be kept constant within 20.0 +- 0.1 °C (actual temperature in range of 19.98 to 20.05 °C). The relative standard deviation (RSD) of three replicate measurements should be ≤ 2% (actual value 0.04%).
Description of key information
Key value for chemical safety assessment
- Relative density at 20C:
