Expiration Date: January 01, 2001
Type:
relative density
Density:
1.76 g/cm³
Temp.:
20 °C
Conclusions:
The density of the test article FAT 40549/A was determined to be 1.76 g/cm3 using a gas comparison pycnometer.
Executive summary:

The determination of the density of FAT 40549/A was based on the EEC directive 92/69, Annex V, Part A, Methods for the determination of physico-chemical properties, A3 "Relative density", EEC Publication No. L383, December 1992 and the OECD Guideline No. 109, "Density of Liquids and Solids" adopted May 12, 1981.

The density of FAT 40'549/A was determined using the gas comparison method at a temperature of 20 ± 0.5 °C. The calibration procedure was performed by triplicate measurements. The determination of the density was performed by triplicate measurements of two independent test article samples.

Based on the findings of the study, the density of the test article FAT 40549/A was determined to be 1.76 g/cm3 using a gas comparison pycnometer.
