PAC LP Announces the Approval of a New ASTM Method D 7346 for the ISL MPP 5GS Product
Jan 11 2008
The no flow point of petroleum products is an index of the lowest temperature of its utility for some applications. Cold flow characteristics such as no-flow point can be critical for the operation of lubricating systems, fuel systems and pipeline operations. It requires precise measurement of the flow properties. The detection
principle is based on continuous monitoring of variation of air pressure within closed test specimen chamber. The test specimen is continuously tested until reaches the temperature where it stops to flow when undergoing cooling. D 7346 method covers sample range of lubrication & base stock oils, PAO, distillate fuels and biodiesel. Comparing to other test methods the instrument provides a higher resolution and uses only a sample volume of less than 1 mL.
In close cooperation with the petroleum industry PAC introduced the Automated ISL MPP5Gs Analyser that incorporates the new ASTM D 7346 method. To estimate the method precision for determining the no-flow point, ASTM conducted an interlaboratory test study consisting of 26 laboratories and 38 sample sets ranging from base oils, various lubricating oils up to fuel oils and biodiesel. The ASTM D 97 method was used as a control check since cold flow properties are typically measured by pour point. The test results demonstrated that the no-flow method is a robust technique for cold flow properties determining and provides equal precision for both known and unknown samples. The MPP5Gs is an ultra compact, easy to use instrument that automatically sets all test conditions. You will benefit from continuous measuring with highly precise results, no-flow, cloud & pour point determinations in one test run, fast results available within 20 minutes for a -30°C pour point, high automation with built-in 10 position sample changer, ultra low temperature testing to - 95°C, built-in cooling system, compact and portable system that easily moves within your lab and at-line.
