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

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

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.
