\n Significance and Use <\/b><\/p>\n
\n

4.1 Knowledge of the amount of ash-forming material present in a product can provide information as to whether or not the product is suitable for use in a given application. Ash can result from oil or water-soluble metallic compounds or from extraneous solids such as dirt and rust.<\/p>\n<\/p><\/div>\n

1. Scope <\/b><\/p>\n

\n

1.1 This test method covers the determination of ash in the range 0.001\u20130.180 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<\/span> ). The test method is limited to petroleum products which are free from added ash-forming additives, including certain phosphorus compounds ( Note 2<\/span> ).<\/p>\n

Note 1 <\/span> \u2014 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. <\/span>\n <\/div>\n
Note 2 <\/span> \u2014 This test method is not intended for the analysis of unused lubricating oils containing additives; for such samples use Test Method D874<\/span> . Neither is it intended for the analysis of lubricating oils containing lead nor for used engine crankcase oils. <\/span>\n <\/div>\n<\/p><\/div>\n
\n

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 %.<\/p>\n<\/p><\/div>\n

\n

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. <\/i><\/p>\n<\/p><\/div>\n
