In the U.S. the most common method of measuring LFLs and UFLs is ASTM E681. This standard test is required for HAZMAT Class 2 Gases and for determining refrigerant flammability classifications. This standard uses visual observations of flame propagation in 5 or 12 L spherical glass vessels to measure the flammability limits. Flammable conditions are defined as those for which a flame propagates outside a 90° cone angle. WebThe calculated LFL varies from 3% at 1000 K to 4.8% at 1500 K. The calculated UFL varies from 60% at 1000 K to 68% at 1500 K. At the reported literature flammability limits (LFL of 5% and UFL of 60%), the methane-oxygen system has a threshold theoretical flame temperature of 1500 K.
