other: International Electrotechnical Commision (IEC), IEC standard 79-4: "Electrical Apparatus for Explosive Gas Atmospheres, Part 4, Method of Test for Ignition Temperature", 1975.
Deviations:
no
Principles of method if other than guideline:
The auto-ignition temperature of the test substance was determined using a commercially available auto-ignition temperature apparatus (Chilworth Technology, Southampton, UK). The method is applicable to test substances with an auto-ignition temperature in the range 75°C -650°C. In every ignition test, liquefied test substance was introduced into a preheated test vessel using a volumetric pipette. It was observed visually whether a reaction (clearly perceptible flame and/or explosion) of the sample within five minutes after introduction took place at the prevailing temperature. After each ignition test, any vaporizable components left in the flask were blown out with air (Air Products, Amsterdam, The Netherlands).
GLP compliance:
yes (incl. certificate)
Key result
Auto-ignition temperature:
425 °C
Atm. press.:
>= 1 005.5 - <= 1 023.5 hPa
Conclusions:
Commercially available auto-ignition temperatures apparatus was used for the determination of the degree of auto-ignitability of Standolized linseed oil. The test substance is auto-ignitable with an auto-ignition temperature at 1005.5 - 1023.5 hPa of 425°C.

Additional information

Commercially available auto-ignition temperatures apparatus was used for the determination of the degree of auto-ignitability of Standolized linseed oil. The test substance is auto-ignitable with an auto-ignition temperature at 1005.5 - 1023.5 hPa of 425°C. This observation is read across to Standolized Soybean oil.
