In 2024, the GFC is organizing round robin tests on the following methods:

Coolant Corrosion Glassware GFC-FL-22

Coolant Corrosion Hot Plates GFC-FL-108-X-04

Coolant Alkalinity Reserve GFC-FL13/FL111

Coolant foaming GFC-FL-10

Coolant Dynamic Corrosion GFC-FL-23

Coolant Ageing by Measurement of GFC-FL-24 Glycolates

GFC-SG2-95 Oil Micro-Coking Test

GFC-SG3-10 Oil Panel Cocker Test

Pistons rating

Rolling on greases ISO 12940

Improvement of the NF T60-144 standard on Grease Sulphated ash

Thermal Ageing of Oils under Nitrogen GFC-TR-41-A-14

Participating is a win-win approach: Statistical validity is improved by a larger number of participants and they can check their good practices, compare themselves to other laboratories (anonymously) and obtain a certificate of proficiency at a very low cost. (Rule 5.4 of the GFC by-laws)

A company that is not a member of the GFC may participate in a round robin tets if it owns (or purchases) the corresponding method and pays a contribution for the costs of organization estimated at half the price of the annual membership fee to the corresponding technical committee; This payment does not give access to the meetings of the committee, but to the meetings of the working group for the organization and results of the trial.
