1.1 This test method covers the determination of the existent gum content of aviation fuels, and the gum content of motor gasolines or other volatile distillates in their finished form, (including those containing alcohol and ether type oxygenates and deposit control additives) at the time of test.<\/p>\n

1.2 Provisions are made for the determination of the heptane insoluble portion of the residue of non-aviation fuels.<\/p>\n

1.3 The values stated in SI units are to be regarded as the standard. The accepted SI unit of pressure is the Pascal (Pa); the accepted SI unit for temperature is degrees Celsius.<\/p>\n

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 6.4, 7.4, and 9.1.<\/p>\n
