ASTM D612

ASTM D612 is a test method for determining the oil content in paraffin wax and related petroleum waxes using a refractive index measurement.

Description of ASTM D612 (paraffin wax)

  • Property measured: Oil content
  • Material: Paraffin wax, microcrystalline wax, petroleum waxes
  • Principle: Refractive index
  • Result: Mass percent (%) oil

The presence of oil changes the refractive index of the wax, allowing the oil level to be quantified.
