Mean density pPRfor the four test series: 1.296 g/cm3Relative density (compared to water at 4 °C) D4R: D4R= ρPRW4= 1.296 g/cm3/ 1.000 g/cm3= 1.296

Conclusions:
The relative density of the test item at ambient temperature (compared to water at 4 °C) according to the European Commission Regulation (EC) No. 440/2008 method A.3. and in the OECD 109 was determined to be D = 1.296.
Executive summary:

A study was conducted according to Regulation (EU) No. 440/2008 method A.3 and OECD Guideline No. 109 to determine the relative density of the test item. The density was determined using a gas comparison pycnometer. The relative density of the test item at ambient temperature (compared to water at 4 °C) was determined to be D4R= 1.296.

Description of key information

The relative density of the test item at ambient temperature (compared to water at 4 °C) according to the European Commission Regulation (EC) No. 440/2008 method A.3. and in the OECD 109 was determined to be D4R= 1.296 (reference 4.4-1).
