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)

Conclusions:

The relative density of the test item was determined to be 1.0761 ± 0.00046 g/cm^3 (with 95 % confidence interval) at 20 °C.

Executive summary:

The purpose of this study was to determine the relative density of test item using pycnometer method at 20°C. The relative density of the test item was determined to be 1.0761 ± 0.00046 g/cm³ (95 % confidence interval) at 20 °C.

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.

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.
