Test phenomena

1) The sample temperature could not reach 400 °C until it was heated to its melting point.

2) There was no substance in the vessel after the test completed.

1) The sample temperature could not reach 400 °C until it was heated to its melting point.

2) There was no substance in the vessel after the test completed.

Melting range of CR SB08 was between 171.9 and 175.2 °C.

Conclusions:
According to EU A.16 test method, the relative self-ignition temperature of CR SB08 was above the melting point (171.9-175.2 °C).
Executive summary:

This test using the procedures outlined in the ZCTC Study Plan for PCF2017-003-4 and EU A.16. The relative self-ignition temperature of CR SB08 was above the melting point (171.9-175.2°C).

Description of key information

The relative self-ignition temperature of CR SB08 was above the melting point (171.9-175.2°C) (EC A.16).

Key value for chemical safety assessment
