ELGI Working Groups
The working groups (WGs) are a popular part of the ELGI and the interest and participants increase every year. At the last ELGI AGM in Barcelona close to a hundred people participated in the meetings.
There are currently five active WGs focusing on different aspects of our industry. Meetings are held at least twice a year. One in the spring at the ELGI AGM and one in the fall, usually in Amsterdam. The WGs are not limited to these five groups. As long as there are interested members, new groups covering different topics can be started. The working groups are not only open for members. Quite often industry representatives are invited to give their view and input on a specific topic or more in depth to explain applications and end-user needs.
We are always looking for more active members. So if you have the opportunity, attend a WG meeting. They are not only a great source of knowledge but are also a great opportunity to be able to influence our part of the industry.
initial work were asked to repeat testing using guidelines which could reduce variability introduced by different interpretations and counting methods.
Feedback from OEMs and end-users is actively sought and encouraged to help make these classifications and measurements as useful as possible.
Additional discussion will take place at the next WG meeting in June at the NLGI Annual Meeting in the U.S. and again in November at the ELGI WG meetings in Amsterdam. Those with an interest in contributing to this WG may contact the Chair Joe Kaperick.

Food Grade Lubricants Working Group The Food Grade Lubricants Working Group differs from other ELGI work groups due to its main focus being legislation, health and safety and public concerns. Food Grade lubricants, or better lubricants for incidental food contact are in their function similar to industrial grade lubricants. Where they differ is in the selection of components (HX1) and their production (ISO21469). To make it easy for the user the lubricants are registered at INS (
www.insservices.eu or NSF
www.nsf.org) under the category H1, and the producer can opt to be certified under ISO 21469.

Grease Particle Evaluation Working Group The Grease Particle Evaluation Working Group is a joint working group operating through both ELGI and NLGI. The goal is to arrive at a relatively inexpensive and easy way to evaluate the particles within a grease sample. The three characteristics of interest are size, number and ability to do damage of any particles.
Two methods have been evaluated to date: • Hegman Gauge (size/number of particles by distributing sample of grease within graduated trough and noting number of tracks and size)
• ASTM D1404 Deleterious Particles (acrylic squares used to measure number of particles within grease that cause scratches).
Results shown from three labs that used the similar-sized Hegman gauges showed better reproducibility and gave some hope that variability could be reduced. Labs participating in this
The main focus by the work group during recent times has been to further professionalize our industry and to help the users of the lubricants, the Food, animal feed and pharmaceutical industry, by sending a clearer message separating facts from marketing fiction. Education on the correct use of lubricant products will remain high on the agenda and very necessary. With our responsible behavior toward food safety we can help the law makers and the lubricant users to create safer food stuffs. To support this the ELGI work group has made a position paper that has been published in May 2015 and can be found at

Test Methods Working Group (TMWG) The objective of this ELGI working group is to focus on grease testing, to establish valid, recognised procedures and test methods. The TMWG is a global network of experts in lubricating grease testing and is focused on topics like;
• Rheological Measurements TMWG members are involved in ASTM and DIN working group activities, both are looking for a rheological measurement testing programme separately, resulting in different test method profiles. • Copper corrosion Copper corrosion results can be influenced; additional activities underway to find the reason of the deviation in results in several round robin activities at DIN and ASTM. Aspects like cleaning, filling, equipment and reporting are under investigation. • ELGI Reference Greases
For evaluation on test methods it would be beneficial to build up data based on same reference greases. The TMWG want
