Key result
Remarks on result:
other: 4'-cyanoacetophenone ignites only when the flame of bunsen burner having temperature of 950°C is brought in contact with it.Thus it can be concluded that substance is flammable only at high temperature of about 950°C.
Conclusions:
4'-cyanoacetophenone did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 4'-cyanoacetophenone is not auto-flammable.
Executive summary:

4'-cyanoacetophenone did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that  4'-cyanoacetophenone is not auto-flammable.
