Interlaboratory Crosscheck Program on Biodiesel Now Offered by ASTM International and AOCS

Printer-friendly version

A new Interlaboratory Crosscheck Program (ILCP) on Biodiesel is being offered by ASTM International Proficiency Testing in cooperation with the American Oil Chemists’ Society (AOCS) ( The program will provide participating laboratories with statistics that can be used to improve or maintain high performance levels in their laboratories when conducting routine ASTM biodiesel analyses.

Laboratories involved in the ILCP will be able to compare test results and calculated statistical parameters with those of other laboratories as well as to compare test data for a given quality parameter. In addition, participation will allow laboratories to monitor their own strengths and weaknesses in biodiesel quality testing.

The new program begins in November 2005 and will be conducted three times annually thereafter. Laboratories who choose to be part of the process will receive a biodiesel sample for each test cycle as well as the necessary instructions for the cycle. Test data from the completed determinations will be submitted electronically to ASTM International, and each participant will receive a summary report containing coded laboratory test results; statistical analyses of test data; and charts plotting test results versus lab code. Tests will cover such properties as acidity, carbon resident, corrosion, flash point, sediment, viscosity, and more.

Test trials for 2006 are scheduled for April, August, and November, with a program fee of $555.00 for all three trials. For additional registration information, contact Helen Mahy, ASTM International (phone: 610/832-9683;
