Applicant's summary and conclusion

Conclusions:

In conclusion, the relative density of Solvent Red 119 was deter-mined to be: D20/4=1.601.

Executive summary:

The relative density of Solvent Red 119 was determined using the gas comparison method at a temperature of 20 °C ± 1 °C.

The determination of the relative density was performed by three-fold measurements of two independent test item samples. The individual readings are summarised in Table 1.

The density of Solvent Red 119 was determined to be 1.601 g/cm³ (= 1601 kg/m³) at 20 °C ± 1 °C.
