Summary	This standard applies to the determination of the standard atmospheric pressure (101. 3kPa), the fraction is less than 300��C not more than 5% (volume fraction recovered) containing no additives unused lubricating base oils polycyclic aromatic hydrocarbons (PCA) content, PGA content ranging from 1% (mass fraction) -15% (mass fraction). 1. 2 standard can also be used to determine the polycyclic aromatic hydrocarbons (PCA) content beyond this range and other non-petroleum fractions asphaltenes, but precision has not been determined.
