Summary

Ash analysis in petroleum products according to ASTM D482

This test method covers the determination of ash in the range 0.001 to 0.180% by mass, from distillate and residual fuels, gas turbine fuels, crude oils, lubricating oils, waxes and other petroleum products, in which any ash-forming material is normally considered an impurity or undesirable contaminant. The test method is limited to petroleum products free from ash-forming additives, including certain phosphorus compounds.
