FLOW AND FREEZING POINTS

ASTM D4305; IP 422; ASTM D2386-IP 16(correlation)
Incorporated into: IATA Guidance Materials for Aviation Turbine Fuels
DEF STAN 91-91 (DERD 2494) British Ministry of Defence Specification
ASTM D1655 Specification for Aviation Turbine Fuels

A unique automated instrument providing rapid and accurate freezing point of aviation fuels within the range +5 to -65C. A proven and accepted equivalent to ASTM D2386 with no bias, and fully authorised to release jet A1 Turbine Fuel.

A 5ml sample is progressively cooled using electronic pettier devices thus avoiding the l need for an external cooler.

A constant rate oscillating flow is maintained across a mesh filter, and as the temperature falls, separated wax crystals cause an increase in pressure which is sensed electronically.

Once a 'no flow' pressure is reached the sample is heated until the flow point temperature is reached.

An audible warning is then given and the freezing point is displayed.

Each test cycle takes only 10 to 15 minutes to complete, and the test chamber is cleaned by simply flushing through with sample.

The Point Detector allows simulation of other filterability tests such as IP 219 Cloud Point, IP 319 Cold Filter Plugging Point (CFPP), and SFPP. Fuels with a viscosity greater than 5cSt at -20C will indicate a warmer (i.e.safe) result.

Requires mains power and supply of cooling water.
