Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Relative Density

Two tests with different amounts of the test item were performed to determine the relative density D420 at a temperature of 20 °C ± 0.01 °C.

* The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation (RSD) of ≤ 0.2 %.

The mean density of the test item at 20 °C is 1.5590 g/cm³. The relative density D420 is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).

The relative density is D420 = 1.559.

Final Results

According to OECD Test Guideline 109 (2012), Regulation EC No. 440/2008 Method A.3. and EPA OCSPP Test Guideline 830.7300 (2002), the relative density D420of the test item DMPSA-K2 at 20 °C ± 0.01 °C (compared to water at 4 °C) is D420 = 1.559.
