Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
Experimental test result performed using standard test guidelines
Qualifier:
according to
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Principles of method if other than guideline:
The density of test item is determined by using pyknometer. It is the ratio of mass of the unit volume of test item at a stated temperature to mass of the same volume of gas free distilled water at a stated temperature.
GLP compliance:
no

Conclusions:
The mean density of test chemical was determined to be 0.9843 g/cm³at 20°C and 967.9 hPa.
Executive summary:

The density of test chemical was determined following OECD Guideline 109 and according to the Adapted from ASTM D854-02 using glass pyknometer. The mean density of test item was determined to be 0.9843 g/cm³at 20°C and 967.9 hPa.

Description of key information

The mean density of test chemical was determined to be 0.9843 g/cm³at 20°C and 967.9 hPa.

Key value for chemical safety assessment

Relative density at 20C:
0.984

Additional information

The density of test chemical was determined following OECD Guideline 109 and according to the Adapted from ASTM D854-02 using glass pyknometer. The mean density of test item was determined to be 0.9843 g/cm³at 20°C and 967.9 hPa.

Other supporting study from authoritative predicted databases indicates that the density of test chemical to be to be 1.126±0.06 g/cm3  at 20 degree C and 760 torr pressure, which is close to selected key study value.
