Method concerning safety regulations for the determination of justifiable ignition temperature of liquids, especially oils, following the pattern of the standard DIN 51794. F. Gutte. Erdol Erdgas Kohle, May 1995, 111(5), 203--207.

Mineral oils and vegetable oils can ignite even below the ignition temperature determined in accordance with the standard DIN 51794. Various experiments have been undertaken to develop safer methods and a modified test method for the determination of the lowest ignition temperature of a mixture below the standard-ignition temperature, following the pattern of DIN 51794, has been developed. The existence of a method for determining the ignition of combustible mixtures at hot surfaces being essential, as the standard DIN 51794 is not sufficient for determining the ignition temperature of these mineral oils and vegetable oils. 7 refs.
