The expert from NSG Group presented the document IGPG-02-07.

The group in general was of the opinion that other test procedures should be investigated additional to the Taber test. It was also decided to watch the results of the ISO working group.

Bayer presented the results of their investigation about the possible relevant abrasion tests (document IGPG-02-05). The Technical Services confirmed it is possible to perform some of the proposed test methods.

An additional option was proposed as keeping the Taber test, and adding another relevant one for the plastic glazing. Some ideas were proposed to combine a less severe Taber test (500 cycles) with e.g. car wash test. The Chair recalled in this view document IGPG-01-06 where J proposed some successive tests on the same sample.

The Secretary informed that UNECE regulations are always possible to amend and improve if the necessity appears. OPEL supported this statement and suggested adding the Taber test at a later stage.

The Chair suggested having a closer look to the sand drop test and the Amtec-Kistler test and the proposal raised to organise two round robin tests for those tests:

Sand drop test

• - Companies with equipment for sand drop test are Bayer, MPA, GME (no), NSG Group(?) and Daimler (no) (to check internally).
• - Information about the equipment must be provided, for the sand drop itself as well as for the haze measurement.
• - Dr. Dümmler (MPA) to lead the task force.
• - Samples to be delivered by Bayer, NSG Group, Polyplastic. (50 X 50 mm)
• - Results expected for November meeting (IGPG-03)

Car wash (Amtec-Kistler)

• - Companies with equipment for car-wash are Bayer, Opel, Renault (?), Darmstadt Universität(GFTN, Prof May), Daimler, JAMA (?), VW (?)
• - Samples to be provided by Bayer, NSG Group, Polyplastic
• - Dr. Buckel (Bayer) to lead the task force.
• - Results expected for November meeting (IGPG-03)

Conclusion:

• - Setting up of a task force evaluating the “sand drop” test
• - Setting up of a task force evaluating the “Amtec-Kistler” test
• - Each task force to provide their results for the 3rd meeting of the informal group (21-22 November 2011, Leverkusen – D)
