ASTM D7462-08<\/h3>\n

Historical Standard: Standard Test Method for Oxidation Stability of Biodiesel (B100) and Blends of Biodiesel with Middle Distillate Petroleum Fuel (Accelerated Method)<\/h4>\n
\n

ASTM D7462<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers a measurement of the oxidation stability of biodiesel (B100) and blends of biodiesel with middle distillate petroleum fuels under specified oxidizing conditions at 95\u00b0<\/span>C. Specifically, the oxidation stability is assessed by the formation and measurement of insoluble degradation materials.<\/p>\n

Note<\/span> 1\u2014Biodiesel B100, composed of alkyl esters, can have good solubility for some products of oxidative degradation. Thus some B100 samples could undergo significant degradation, but show little or no sediment formation. By contrast, many petroleum diesel fuels have relatively poor solubility for products of oxidative degradation, so Bxx blends, such as B20, could show higher sediment levels. Refer to Appendix X1 for a suggested paraffinic dilution procedure to evaluate oxidative degradation of B100 for degradation materials that are soluble in B100, but insoluble in iso-octane.<\/p>\n

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\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.<\/span><\/p>\n
