Pnv = Quoted pycnometer volume

Sd = Sample density

PnSw = Weight of pycnometer with sample

Conclusions:

The density of the test item was determined to be 1.1428 g/cm3 at 22.3°C.

Executive summary:

Crane J (2018) is a GLP-compliant study following OECD guideline 109 and is therefore reliable without restrictions (Klimisch 1). The pycnometer method was used to determine density of the test item. The measurements were performed in triplicate.

The density of the test item was determined to be 1.1428g/cm3 at 22.3°C. The test is considered valid as all three replicates were found to be within the ±5% of the average density for the test.

Description of key information

The density of the test item was determined to be 1.1428 g/cm3 at 22.3°C.

Key value for chemical safety assessment

Relative density at 20C:
