Mr. Hara presented document IGPG-06-02 on behalf of FGMAJ and recalled that the intention is the improvement of the Daiwa wheels for reaching the Taber test performance requirements. The two 1st trials were not successful, but this 3rd trial was a success: it was possible to reach the 2% Haze difference with the new Daiwa wheels.

Some wheels reached a 2% haze difference on plastic shields, but had almost 0% on glass (Trial F).

Mr. Hara concluded that there is still a need for further improvements for being able to use the same wheels for glass and plastics.

The delegate from France stated that there is a need that Plastic provides the same performance as the glass, while the FGMAJ presentation seems that it is an attempt to change the tool for ensuring that Plastic can be used. The delegate from France questioned the utility of developing new wheels.

Mr. Dümmler found it unusual to develop wheels which provide a haze of 2% on Plastics.

Dr. Buckel recalled that Taber changed the wheels without providing any information on the change, and that the today situation comes from the fact that there is no description of the wheels and their “abrasiveness”. All kinds of abrasions must be taken into account for the abrasion test, and the plastic materials do not react the same way as the glass panes. F repeated the need to maintain the Taber test, and agreed on the development of a new test simulating the real conditions. The delegate from France was reluctant, as representative of a Technical Service, to be obliged to replace the Taber machines currently in use.
