The test item showed five stages of melting viz. beginning of melting/wet point, shrinking point, collapse point, liquefying point and final stage of melting with no solid particles left.

Applicant's summary and conclusion

Conclusions:
The melting point of fully hydrogenated high erucic acid rapeseed oil was found to be in the range of 58 to 63 °C.

Executive summary:

The melting point of fully hydrogenated high erucic acid rapeseed oil was determined by the capillary method using an electronically controlled heating system according to OECD Guideline 102, EU Method A.1 and EPA OPPTS 830.7200.

In the preliminary test, a sample of the test item in a capillary glass tube heated from room temperature with a rate of approximately 10 ºC/min. to estimate phase transition temperature. For the actual determination of the melting point, the temperature rise adjusted to a maximum of 1 ºC/min. at about 15 ºC before and after the predetermined phase transition temperature.

The melting point of fully hydrogenated high erucic acid rapeseed oil was found to be in the range of 58 to 63 °C.
