Type of information:

experimental study

Adequacy of study:

key study

Study period:

29 October 1998

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.3 (Relative Density)

Deviations:

no

GLP compliance:

yes

Type of method:

air comparison pycnometer (for solids)

Type:

relative density

Density:

1.29

Temp.:

24.3 °C

Two test series where carried out on the substance:

Weight / g	11.7349	12.7157
Volume / cm^3
1. measurement	9.20	9.92
2. measurement	9.17	9.87
3. measurement	9.15	9.89
Mean	9.17	9.89
Density g / cm^3	1.28	1.29

 

Conclusions:

The relative density (compared to water at 4 °C) is DR4= 1.29

Executive summary:

The purpose of the test was the determination of the relative density according to Guideline 92/69/EEC of 31 July 1992, Annex. Part A: Methods for the determination of physico-chemical properties. A.3. Relative Density. The study was conducted in compliance with the Principles of Good Laboratory Practice (GLP).

 

The density of a solid in any form can be measured at room temperature with the gas comparison pycnometer. The volume of a substance is measured in air or in an inert gas in a cylinder of variable calibrated volume. For the calculation of density one mass measurement is taken after concluding the volume measurement. Instrument: gas comparison pycnometer, model 930 (Beckmann).

 

The relative density (compared to water at 4 °C) is D^R₄= 1.29

Description of key information
