Key result
Remarks on result:
other: C.I Direct Blue 218 (CAS no. 28407-37-6) not ignited when the flame of bunsen burner having temperature of approximately 950°C was brought in contact with it.
Interpretation of results:
other: non flammable
Conclusions:
C.I Direct Blue 218 (CAS no. 28407-37-6) does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that C.I Direct Blue 218 (CAS no. 28407-37-6) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus C.I Direct Blue 218 (CAS no. 28407-37-6) was considered non-flammable for chemical safety assessment.
Executive summary:

C.I Direct Blue 218 (CAS no. 28407-37-6) does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that C.I Direct Blue 218 (CAS no. 28407-37-6) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus C.I Direct Blue 218 (CAS no. 28407-37-6) was considered non-flammable for chemical safety assessment.
