Since dust may choose machines, the ignition temperature from the dust layer (smouldering temperature) will have to also be viewed as. The smouldering temperature is the lowest temperature of a warm floor on which a dust layer of five mm can ignite. Adjustment depending on the most equipment surface tempera- ture is done with a security element of seventy five K.
