Application Report Diana 700: ASTM D86 - ASTM Proficiency Testing Program for Distillation of Motor Gasoline

Anton Paar participated in the ASTM Proficiency Testing Program to test the gasoline sample MG 1808 with the Diana 700 and achieved convincing results.

Introduction

Quality and reliability of test results are essential for laboratories. The ASTM Proficiency Testing Program (PTP) is a valuable tool for laboratories and instrument manufacturers worldwide to conduct equal tests on the same material in accordance with the same test method. ASTM will evaluate the performance of the laboratories by arranging a statistical analysis of the results.

Participating in interlaboratory studies (ILS) organized by the German standardization body DIN or the European Standardization Committee EN for more than 20 years, ILS have a long history with Anton Paar.

To verify the excellent precision of Anton Paar’s distillation analyzer and to extend the geographical range of these interlaboratory tests to a worldwide level, we have now participated in the ASTM Proficiency Testing Program with the Diana 700. In this PTP the gasoline sample MG 1808 was analyzed by all participating laboratories (approx. 125 laboratories).

The given standard was ASTM D86 covering the atmospheric distillation of petroleum products and liquid fuels. In general, ASTM D86 defines a method to determine quantitatively the boiling range characteristics of materials such as automotive spark ignition fuels, aviation gasolines, diesel fuels, light and middle distillates.

ASTM organizes the ILS and conducts the statistical analysis of the reported results. The results (evaporated temperature values) of the Diana 700 were found to be much better than the ASTM D86 reproducibility defining the allowed temperature range as shown in the comparison table.

This Application Report describes the distillation of gasoline performed with the distillation analyzer Diana 700 for the ASTM Proficiency Testing Program. You will get information about all accessories you need and how you have to set up your Diana 700 to obtain excellent results.
