Popis

BS 2000-346:1996


This standard BS 2000-346:1996 Methods of test for petroleum and its products is classified in these ICS categories:
  • 75.100 Lubricants, industrial oils and related products

1.1 This method specifies the determination of polycyclic aromatics (PCA) over the concentration range 1–15 mass % in unused additive free lubricating base oils having an atmospheric boiling point of 300°C minimum at 5% recovered sample. This method may apply to PCA concentrations outside this range and to other asphaltene-free petroleum fractions, but the precision has not been determined.


Identical with IP 346/92(98).
