Conclusions:

The relative density of N,N-bis(2-hydroxyethyl)-p-phenylenediamine sulphate monohydrate was determined to be 1.497.

Executive summary:

The relative density of N,N-bis(2 -hydroxyethyl)-p-phenylenediamine sulphate monohydrate was determined according to DIN EN ISO 2811 which succeeds DIN 53217 referenced in EU test method L383 A/21-25 (EU A.3). The determination was performed by the pycnometer method. Shellsol T was used as the immersion liquid since the test item was soluble in water. The relative density (D₄²⁰) was determined to be 1.497.

Description of key information
