Applicant's summary and conclusion

Conclusions:

The relative density of fully hydrogenated coconut oil was found to be 0.96 at 20 °C.

Executive summary:

The relative density of fully hydrogenated coconut oil was determined using the gas comparison method according to OECD Guideline 109, EU Method A.3 and EPA OPPTS 830.7300.

Volume of the reference and the sample cells was determined using calibration balls. The density of the test material was determined by weighing the cells before and after filling with test material. The test procedure was repeated until a repeatability of < ± 0.02 g/cm³ was reached. The determination of the relative density was performed by threefold measurements of two independent test item samples.

The relative density of fully hydrogenated coconut oil was found to be 0.96 at 20 °C.
