Reference
Apparatus
Pycnometer with thermometer 25 mL, described by DIN ISO 3507, No.: 10.06 89
Balance, BP 210D Sartorius (accuracy: 0.01 mg), No.: 60602907
Temperature controlled room: 20 °C ± 1 °C
Water purification system, MILLIPORE, DIRECT-Q5, No.: F0DA13956K
Principle of the Test
The density is calculated from the difference in weight between the full and empty pycnometer and its known volume.
Calibration of the Pycnometer
The calibration was performed with ultra-pure water. The empty, clean pycnometer (with all accessories) was weighted (m1) with an accuracy 0.01 mg in eight replicates. The water was transferred into the pycnometer at 20 °C (in a thermostated room). After the temperature became stable the pycnometer was levelled using a syringe. The outer wall of the pycnometer was cleaned and dried and its weight was measured and recorded with an accuracy of ± 0.01 mg in eight replicates (m2).
Main test
The weight of test item is the difference between the weight of the empty and the levelled pycnometer. The exact volume of the pycnometer is known by measured ultrapure water according the calibration procedure. The pycnometer was filled with test item in eight replicates and was measured as above described at Calibration of the Pycnometer paragraph. The weight of test item is the difference between the weight of the empty (m1) and the levelled pycnometer (m3). Eight replicate tests were carried out. The density of test item was calculated.
Calculations
Density: ρ = V/W
where: ρ = density of the test item (1 g/cm3= 1000 kg/m3); W = weight (g); V = volume (cm3)
Description of key information
The relative density of the test item was determined to be 1.0761 ± 0.00046 g/cm3 (95 % confidence interval) at 20 °C.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.076
Additional information
The purpose of this study was to determine the relative density of test item using pycnometer method according to EU Method A.3, OECD 109, and EPA OPPTS 830.7300. The density is calculated from the difference in weight between the full and empty pycnometer and its known volume. The relative density of the test item was determined to be 1.0761 ± 0.00046 g/cm3 (95 % confidence interval) at 20 °C.
