Key result
Remarks on result:
other: Zinc distearate did not catch fire on being exposed to air at room temperature of 38 deg C and atmospheric pressure of 755 hPa.
Remarks:
at atm. press. of 755.0 hPa
Conclusions:
Zinc distearate did not catch fire on being exposed to air at room temperature of 37 deg C and atmospheric pressure of 760 hPa. This indicates zinc distearate is not auto-flammable.
Executive summary:

Zinc distearatedid not catch fire on being exposed to air at room temperature of 37 deg C and atmospheric pressure of 760 hPa. This indicates zinc distearate is not auto-flammable.
