ASTM diesel standard now includes PAC distillation method

摘要

ASTM recently published its latest version of the ASTM D975-12 Standard Specificatiomfor Diesel Fuel Oils, which includes an alternate distillation method, ASTM D7345. This alternate method achieves significant response-time improvements compared to the conventional ASTM D86 method. PAC, a global provider of advanced analytical instruments for laboratories and online process applications, developed the ISL PMD 110 and ISL MicroDist instruments, both of which utilize this alternative method. The ISL PMD 110 (FIG. l) is a laboratory instrument that determines the complete distillation curve within eight minutes, using data from one phase transition (evaporation), thus eliminating the process of condensation. The analysis is based on fundamental thermodynamic dependencies. Immediately after test completion, distillation characteristics are calculated from collected data with an ASTM D86/ ISO 3405-compliant, detailed report.
