Anton Paar's SVM Method for Viscosity Testing: Fully Standards-Compliant Petroleum Analysis

Feb 20 2024

In the dynamic field of petroleum analysis, Anton Paar's SVM test method, ASTM D7042, stands out as the industry's newfound benchmark for viscosity testing, ensuring unparalleled precision and accuracy across a wide array of critical fuels and oils.

Anton Paar's SVM exceeds expectations: Mid-tier and high-end models not only adhere to ASTM D7042 but encompass density analysis according to D4052. Moreover, a specialized variant can analyze the cold flow properties of samples, presenting a multi-parameter approach that establishes SVM as a comprehensive solution for characterizing the physical properties of diverse petroleum products.

Versatility in Key Specifications

D7042 is an officially accepted test method in key petroleum specifications such as D975 and EN 590 for distillate/diesel fuels, SAE J300 and D6074 for lubricants, ASTM D396 for fuel oils, D6158 and D8029 for hydraulic oils, D3699 for kerosene, and many more. Notably, in the aviation sector, Anton Paar's SVM method aligns seamlessly with standards such as D1655 for aviation turbine fuels and D7566 for aviation fuels containing synthesized hydrocarbons, as well as JIG AFQRJOS and Def Stan 91-01. Given that density is often specified in these standards, SVM can also be utilized for the certification of this crucial parameter.

Specialized Version for Cold Flow Properties

Anton Paar takes innovation a step further with SVM 3001 Cold Properties. This advanced version not only measures viscosity and density but also determines the freeze point of aviation fuels (correlating to D2386) and the cloud point of diesel fuels (equivalent to D2500). With these additional parameters, SVM becomes an invaluable tool for assessing low-temperature properties, ensuring fuel quality even in extreme conditions.

A Contemporary Device

While adherence to standards is paramount, factors like flexibility, economic viability, and ease of use are equally crucial. SVM viscometers feature robust metal measuring cells with the broadest viscosity range (0.2 mm2/s to 30,000 mm2/s) and temperature range (-60 °C to +135 °C). Requiring only a minimum of 1.5 mL sample and solvent per measurement, they allow for a 150% higher throughput compared to manual methods. Control is facilitated through an easy-to-read touchscreen, eliminating the need for an external PC to run samples or store measurement data. Full automation is also possible when combined with a sample changer.

Competitive Edge

Anton Paar’s SVM is distinguished not just by its efficacy but by the comprehensive nature of its viscosity testing method. Included in over 50 international standards, Anton Paar's SVM stands as the trusted choice for viscosity analysis of petroleum products. Furthermore, its D4052 compliance, coupled with the additional features of SVM 3001 Cold Properties, has redefined precision and versatility in petroleum analysis, paving the way for characterizing newly developed products in the field, such as sustainable aviation fuels.
