Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
From the experimental values of flammability,Zinc distearate ignited when the flame of Bunsen burner having temperature of 950 deg C was brought in contact with it. Thus it can be concluded that Zinc distearate is flammable only at high temperature of about 950 deg C. However since such high temperatures are not found under normal circumstances of transportation and use,Zinc distearate was considered non-flammable.
Executive summary:

From the experimental values of flammability,Zinc distearate ignited when the flame of Bunsen burner having temperature of 950 deg C was brought in contact with it. Thus it can be concluded that Zinc distearate is flammable only at high temperature of about 950 deg C. However since such high temperatures are not found under normal circumstances of transportation and use,Zinc distearate was considered non-flammable.

Description of key information
