ASTM D7525-09<\/h3>\n

Historical Standard: Standard Test Method for Oxidation Stability of Spark Ignition Fuel\u2014<\/span>Rapid Small Scale Oxidation Test (RSSOT)<\/h4>\n
\n

ASTM D7525<\/h4>\n

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

1.1 This laboratory test method covers the quantitative determination of the stability of spark ignition fuel, including those containing alcohols or other oxygenates, under accelerated oxidation conditions, by an automatic instrument (Warning\u2014<\/b>This test method is not intended for determining the stability of gasoline components, particularly those with a high percentage of low boiling unsaturated compounds, as these can cause explosive conditions with the apparatus. )<\/p>\n

1.2 This test method measures the induction period, under specified conditions, which can be used as an indication of the oxidation and storage stability of spark ignition fuel.<\/p>\n

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

1.4 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.<\/span><\/p>\n
