Management Board

Unconfirmed Minutes from the last Management Board meeting, held on 15th May 2008, are now available to CEC Working Group members on the CEC Web Site.


Important Information About CEC L-85-T-99 PDSC Test

We are reporting the background to changes to the L-85-T-99 test & the potential impact on the ACEA limits.

This test involves heating a small amount of oil in an aluminium pan under a set of parameters laid out by the test. The stipulated pans are single use, disposable test parts & manufactured by Seiko.
The test result is a time (minutes) reflecting the oxidative stability of an oil. The test uses 2 reference oils, RL133 & RL134, of which RL133 is the more useful.
The L-85-T-99 group noticed a shift to higher test results for RL133 & RL134 & this coincided with Perkin Elmer becoming the sole worldwide distributor of the pans.
RRs were undertaken & the change in results was attributed to the pans. Results indicated a single batch of pans gave best results (reduction in r & R).
Discussions were held with Perkin Elmer as to the change. The group tried to have Perkin Elmer prepare a batch of pans dedicated to L-85-T-99 group members, but were let down in the later stages.
TA Instruments offered a suitable pan & reserved a batch of pans for CEC group members use.
Individual L-85-T-99 members have purchased sufficient pans for a minimum of 3 years, most likely longer.

The ACEA E3 limit of 35 minutes, established in ~2000 using Seiko pans was based on RL133 RR data, derived from:
RL133 mean value – 2 x Standard Deviation
Using RL133 the 2007 RR values obtained using TA Instrument pans were:
RL133 mean = 74.5 minutes
Standard Deviation: 2.44 minutes

The Test Method is in the process of being updated and produced electronically. It is expected to include a Precision Statement and will be made available as CEC L-85-99 (dropping the old ‘T’ Status designation from its title).


SG-L-099 – OM646LA

This sponsored test development has been completed.
The Test Method CEC L-99-08 was officially accepted by the CEC Board on 15th May 2008 for the cam outlet wear parameter. The Group moved to Surveillance upon publication of the official approved procedure (23rd May 2008).
Companies are now able to purchase a licence from CEC to use this test, at a cost of Euro 89,602. This entitles the company to access the Test Method on the CEC Web Site and membership of SG-L-099 meetings. Please contact the CEC Secretariat if you are interested in the Test Method.


SG-F-098 – DW10 Test

A Round Robin is taking place using B10 fuel.
The Group needs a stable blend of B10 to deliver the required power reductions and to store as a reference fuel. The Group would prefer to find a non-metal-containing poor reference fuel.
Income from sales of this Test Method should be returned to the original sponsors in equal parts, however, if the original sponsors prefer to use the funds for additional testing work then the Management Board will support this, providing that ALL original sponsors agree to the funds being used in this way.


SG-L-101 – OM501 Bore Polishing and Piston Cleanliness Test

Further analysis of results is taking place and investigations continue.  Thus, the test cannot yet be accepted into CEC.


SG-L-036 The Measurement of Lubricants Dynamic Viscosity under Conditions High Shear  (Ravenfield Viscometer)

This test is to be amended.
It now accepts the use of Tannas as well as Ravenfield equipment, following analysis of the results of a recent Round Robin.  A revised and re-named Test Method is expected soon.


Important Information About the CEC Web Site

Please take note of this important information to ensure you get the best use out of the CEC Web Site.
All Working Group Members are set up to receive Automatic Emails and Newsletters sent from the CEC Web Site.  Automatic Emails notify members about new documents that they need to see in their area of the Web Site.  Automatic Emails also notify test method holders about updates to CEC Test Methods.  

If you have not received these automatic emails in the past, you will need to follow the instructions below.

If you do usually receive these Automatic Emails and regular CEC Newsletters, please note that on Friday 13th June 2008 we shall be moving the CEC Web Site onto a new web server, co-located with the new CEC Test Monitoring system.

To prevent any problems with receiving Newsletters and Automatic Emails, please inform your IT department to update your firewall and spam filter whitelist to allow you to receive e-mails directly from the CEC Web Site.  Please logon to the CEC Web Site Members page, select ‘CEC Web Site Notifiers’ from the drop-down menu under ‘Document Search’ and you will find the details you need to give to your IT department.


Test Monitoring

The system is now live!
It is being introduced to Working Groups in phases, as validation and testing is completed for each test.  There are favourable responses about the clarity and user friendliness of the new system.  It will provide good detail to analyse when problems or drifts in results occur.  The Admin Report will show clearly which laboratories are inputting test data and if their results are in control.


Test Methods – Section 5 Calibration Methods

There is a proposal to update Section 5 of all CEC Test Methods.
It was originally compiled in 1998 by a CEC Calibration Task Force and issued to all Group Chairmen. The original aim was to encourage a consistent approach to the calibration process, thus achieving the ultimate goal of consistency between all engine test laboratories. Since its publication the CEC has issued (via the EA) ISO 17025 interpretation Document CEC-P-01-02 and European norms have been issued covering measurement vocabulary, measurement uncertainty, traceability and determining appropriate calibration intervals. A revised Section 5 has been modified to include these changes and sent out to all Working Group Chairmen for their comments.
In addition, Phil Baxter at Lubrizol has agreed to take on a co-ordinating role for any additional parameters that might be proposed by a Group to be included for calibration / measurement issues. Once the listing is defined after input by Working Group Chairmen, the new Section 5 will be added to Test Methods during regular updates. Any deviations from the standard wording will be referred to Phil for approval before publication.


Rating Workshop

The next Rating Workshop takes place at ISP, Salzbergen on 3-5 June 2008.
This is for raters of the OM646LA Piston and Sludge Rating and Wear Measurement.  Details about how to register for this Workshop are available on the public part of the CEC Web Site.


CRC Rating

CRC has discontinued its involvement in deposit / distress rating.  
ASTM International has assumed the rating responsibilities from CRC with the ASTM Test Monitoring Center responsible for conducting rating workshops and ASTM Intl. headquarters responsible for CRC Manuals 20 and 21 and other rating scales and aids.
For contact details please logon to the CEC Web Site Members page and select ‘All News’ under the News Zone.
