Presentation on status of the work on development of wiper tests for plastic glazing.
A status report was provided by Dr. Buckel on behalf of VDA. Dr Buckel informed that seven brands currently take part to the test campaign decided by the sub-group 1 of the Task-Force on Wiper-test.
Three vehicles started their on road testing:
BMW 3 Series:
- was on the road during 2 months
- one windscreen under on-road test
- Laboratory cycles on a 2nd windscreen (complete).
- investigation of deterioration in progress
VW GOLF 6:
- 3 months on the road, then investigation in laboratory.
- Intention to test one further vehicle.
Porsche Cayman:
- On road since May 2012
- Backlight is tested
- Road test on-going
The vehicles are driven in common conditions (safeguarding cars).
There is currently no information about the coating of the windscreens, but it is expected that all necessary information will be given. KRD with coating from Momentive was the supplier of one windscreen.
Evaluation of a different measuring technique based on light diffraction by the windscreen scratches.
Conclusion:
- Investigation is on-going
- no change in the timeline.
