Covers test apparatus and test procedure for determining ignition temperature of a chemically pure gas or vapour in air at atmospheric pressure, with particular reference to gases and vapours used in hazardous locations. Some established temperatures are tabulated.

This standard describes a method of test for use in the determination of the ignition temperature of a chemically pure vapour or gas in air at atmospheric pressure.NOTE: The ignition temperature of a compound increases as the pressure decreases below one atmosphere (i.e. 101.325 kPa), the rate of change depending on the compound concerned, e.g. it can be as much as 0.7 C/0.133 322 kPa for a linear rate of change. This rate of change may not, however, necessarily be linear.For the above reasons, the acceptance of ignition temperatures determined by laboratories at elevated altitudes for installations at lower altitudes, e.g. at sea level, could lead to danger. The degree of danger can only be quantified in each individual case.
