The onset temperature indicated corresponds to the extrapolated onset temperature given by the intersection of the tangent drawn at the point

of greatest slope on the leading edge of the endotherm peak, with the extrapolated baseline.

The melting point is considered to correspond to the extrapolated onset temperature.

The melting point of the technical material was found to be 297.6°C.
