|  | The Consumer Product Safety Commission (CPSC) requires flammability labels on aerosol household products based on aerosol flame extension testing. The test procedure requires that the formulated product be sprayed through a lighted candle from a distance of 6 inches. The length of the flame is measured and the presence of "flashback" is noted. Flashback occurs when the flame extends back to the aerosol dispenser.
| Flame Extension Tests
Aerosol flame extension tests for each ExxonMobil Chemical LVP Fluid were conducted with aerosol containers filled by volume with test fluid so that there was a constant head space in each. Carbon dioxide (CO2) was selected as the propellant to eliminate the effect of flammable propellants on the test results. A Precision aerosol valve assembly was used with a Neoprene® stem gasket, 0.018 inch stem orifice and a 0.08 inch valve body orifice with no vapor tap. Two different actuator buttons were used: 1) 0.02 inch MBFT Precision actuator button that gives a narrow 3-4 inch wide "cone-shaped" spray pattern at 12 inches, and 2) 0.02 inch Precision combo actuator button that gives a narrow "stream" spray pattern.
In all cases, the flame extension was greater than 18 inches with both actuator buttons and there was no flashback with any of the cans tested. In the test with the narrow "stream" pattern, Isopar V Fluid did not ignite.
