ASTM D7397 Determination of the cloud point of petroleum and biodiesel fuels

ASTM D7397 and D5773 (as used in Phase Technology CPA-T30 and 70X analyzers) are the only automatic methods for determining cloud point allowed in ASTM D6751 the specification used to control pure biodiesel (B100) quality prior to blending with conventional diesel type fuels.

ASTM D7397 and D5773 are included as methods for determining cloud point in ASTM D7467, the specification that covers finished fuel blends of between six (B6) and twenty (B20) percent biodiesel for on- and off-road diesel engine use.

Cost-saving Benefits With Big Payoffs

  • Optimize additives
  • Monitor fuel quality

Precision & Portability at an Economical Price

  • Unsurpassed precision
  • Super fast speed
  • Compact, portable design
  • Completely self-contained system
  • Incredibly simple to use

The CPA-T30 is designed to test the cloud point of middle distillate fuels. These typically include light to middle distillate Number 1 or 2 fuels, biodiesel and biodiesel blends intended for light- or heavy-duty diesel engines.

For operability purposes and adequate cold weather protection, the diesel cloud point should be a minimum of 7 °F (approximately 4 °C) below the lowest anticipated ambient temperature that the fuel is expected to operate. For biodiesel, a minimum 10 °F (approximately 6 °C) difference is recommended.

Phase Technology CPA-T30 Analyzers can be used in both the lab and field.
