The repeatability was better than 0.0001 g/mL at both temperatures.

Conclusions:
Under the test conditions, the density of the test material was determined to be 1.0742 and 1.0698 g/mL at 20 and 25 °C respectively.
Executive summary:

A study was performed to determine the density of the test material using an Anton Paar DMA 4500 Digital Density Meter. The study was conducted according to OECD Guideline 109.

 

Duplicate measurements were made at 20 and 25 °C. NIST traceable toluene was used as a standard for instrument calibration.

 

Under the test conditions, the density of the test material was determined to be 1.0742 and 1.0698 g/mL at 20 and 25 °C respectively.

Description of key information

The density was determined according to OECD Guideline 109 (Pepe, 1995 and Rivera, 2010).
