Conclusions:

The relative density of cC6O4 ammonium salt was determined to be = 1.909.

Executive summary:

The determination of the relative density of the test item was performed in accordance with theDirective 92/69 and Council Regulation (EC) No. 440/2008, Part A, Methods for the determination of physico-chemical properties, A.3 ”Relative density” and the OECD Guideline for Testing of Chemicals, No. 109, ”Density of Liquids and Solids”, using a gas comparison pycnometer.

The density of the test item cC6O4 ammonium salt was determined to be 1.909 g/cm³ (= 1.909 · 10³ kg/m³) using a gas comparison pycnometer. The relative density of cC6O4 ammonium salt was determined to be D ⁴ ₂₀ = 1.909.
