Calibration check

Measured values for Indium:

- Onset temperature : 156.7°C

- Enthalpy of melting : 29.0 J/g

The measured values are within the acceptance limits

Test method 1: Thermal analysis method:

An endothermic peak was obtained. This is the melting range of Ethylene glycol dibenzoate (EGDB). The average (extrapolated) onset endpoint of the melting range is 70.4°C, rounded 70°C. The average enthalpy of the melting endotherm is 137 J/g.

Conclusions:
The melting point of Ethylene glycol dibenzoate (EGDB), CAS 94-19-5, was determined to be 70°C, based on the extrapolated onset.
Executive summary:

The melting point of Ethylene glycol dibenzoate was determined according to EC Regulation No 440/2008, Guideline A.1 and according to OECD Guideline 102, and in accordance with European Chemicals Agency (ECHA), Guidance on information requirements and chemical safety assessment, Chapter R.7a, Endpoint specific guidance, May 2008. The melting point was determined using thermal analysis

The melting point of the test substance is 70°C.
