Key result
Remarks on result:
other: Acid Yellow 49 (CAS no. 12239-15-5) 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:
Acid Yellow 49 (CAS no. 12239-15-5) 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 Acid Yellow 49 (CAS no. 12239-15-5) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Acid Yellow 49 (CAS no. 12239-15-5) was considered non-flammable for chemical safety assessment.
Executive summary:

Acid Yellow 49 (CAS no. 12239-15-5) 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 Acid Yellow 49 (CAS no. 12239-15-5) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Acid Yellow 49 (CAS no. 12239-15-5) was considered non-flammable for chemical safety assessment.
