Conclusions:
The melting point/melting range of HAT ISO was determined according to EU Method A.1 The melting range of the test article was determined to be 239 to 252 °C (512.15 to 525.15 K).
Executive summary:

The melting point/melting range of HAT ISO was determined by the Kofler hot bar method. The temperatures corresponding to the beginning and to the end of the melting process were noted. The melting range of HAT ISO was determined to be 239 to 252 °C (512.15 to 525.15 K).

Description of key information

The melting point/melting range of HAT ISO was determined according to the Kofler hot bar method (EU-Method A 1, Boiling point). The melting range of HAT ISO was determined to be 239 to 252 °C (512.15 to 525.15 K).

Key value for chemical safety assessment
