Any other information on results incl. tables

Calculations:

The density was calculated using Equation 4.1 to Equation 4.4.

* Equation 4.1:

Reference cell volume (cm3): Vref = Vcal / (P1/P2 - P3/P4)

* Equation 4.2:

Sample cell volume (cm3): Vcel = Vref (P1/P2 - 1)

* Equation 4.3:

Test item volume (cm3): Vsample = Vcell - Vref (P1(sample)/ P2(sample) - 1)

* Equation 4.4:

Density (kg/m3): p = 1000 m/Vsample

where:

Vsample: Volume of the test item (cm3)

Vcell: Volume of the sample cell (cm3)

Vref: Volume of the reference cell (cm3)

Vcal: Volume of the calibrated sphere (56.559 cm3)

m: Amount of test item (g)

P1: Pressure reading after pressurizing reference cell without calibration sphere (psi)

P2: Pressure reading after including sample cell without calibration sphere (psi)

P3: Pressure reading after pressurizing the reference cell with the calibration sphere (psi)

P4: Pressure reading after including sample cell with calibration sphere (psi)

P1(sample): Pressure reading after pressurizing the reference cell (with test item) (psi)

P2(sample): Pressure reading after including sample cell (with test item) (psi)

p: Density of the test item (kg/m3)

Applicant's summary and conclusion

Conclusions:
The density of the test item has been determined to be 1440 kg/m3 at 20.5 ± 0.5°C.
Executive summary:

The registered test item has a density of 1440 kg/m3 at 20.5 ± 0.5°C, using a gas comparison pycnometer, designed to be compatible with Method 109 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
