Key result
Remarks on result:
other: C.I. Pigment Violet 1 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:
C.I. Pigment Violet 1 did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that C.I. Pigment Violet 1 is not auto-flammable.
Executive summary:

C.I. Pigment Violet 1 did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that C.I. Pigment Violet 1 is not auto-flammable.
