ASTM D2502-14<\/h3>\n

Historical Standard: Standard Test Method for Estimation of Mean Relative Molecular Mass of Petroleum Oils from Viscosity Measurements<\/h4>\n
\n

ASTM D2502<\/h4>\n

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

\n

1.1 This test method covers the estimation of the mean relative molecular mass of petroleum oils from kinematic viscosity measurements at 100\u2009\u00b0F and 210\u2009\u00b0F (37.78\u2009\u00b0C and 98.89\u2009\u00b0C).2<\/sup><\/span> It is applicable to samples with mean relative molecular masses in the range from 250 to 700 and is intended for use with average petroleum fractions. It should not be applied indiscriminately to oils that represent extremes of composition or possess an exceptionally narrow mean relative molecular mass range.<\/p>\n<\/p><\/div>\n

\n

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.<\/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
