Ash can result from oil or water-soluble  metallic compounds or from extraneous solids such as dirt and rust.1.1 This test method covers the determination of ash in the range 0.001x2013;0.180 mass %, from distillate and residual fuels,  gas turbine fuels, crude oils, lubricating oils, waxes, and other petroleum  products, in which any ash-forming materials present are normally considered  to be undesirable impurities or contaminants (Note 1). The test  method is limited to petroleum products which are free from added ash-forming  additives, including certain phosphorus compounds (Note 2).   Note 18212;In certain types of samples, all of the ash-forming metals are not retained quantitatively in the ash. This is particularly true of distillate oils, which  require a special ash procedure in order to retain metals quantitatively.    Note 28212;This test method is not intended for the analysis of unused lubricating oils containing additives; for such samples use Test Method D 874. Neither is it intended for the analysis of lubricating oils  containing lead nor for used engine crankcase oils.  1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. The preferred expression of the property is mass %. 1.3 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.【中国标准分类号】: E30【国际标准分类号】: 75_08【页数】: 4P.;A4【正文语种】:
