Mr. Zander (BASt) and Mr. Gehring (BGS) presented the results of the BASt study. This study aimed at answering the two following questions:

• - Does the use of plastic windscreens in vehicles lead to a higher injury risk for vulnerable road users, especially for pedestrians?
• - Can the current test procedure (Phantom head drop test) on the approval of glazing according to UN regulation Nr. 43 be used for plastic glazing? Which modifications or extensions might be necessary?

The group held a Q&A exchange:

• - The operators used the same glue for the plastic windscreens as for glass windscreens. The fixations of the windscreens were performed by a firm which is expert in windscreen exchanges. The informal group however acknowledged that the type and quality of glue could have an influence on the state of the windscreen and its aging.
• - Dilatation must also be taken into account to a range of about 10mm/100°c. When the samples were clamped, the dilatation was taken into account (clamping was done at the test temperature). Also, it was stressed that the test vehicle was designed for glass panes rather than for PC. While it could be considered reasonable that a vehicle manufacturer adapts the windscreen frame design to the nature of the windscreen, the operators considered logical not to introduce an additional influencing factor into the study.
• - Also the 3rd dimension can take over one part of the dilatation and, in case of multi-pane glazing, one of the panes can take over the dilatation of the other.
• - Concerning rescuing the occupants, the experts were informed that the rescue teams can use the same cutting tools used for steel panes.

The informal group was informed that it is expected that an additional, more complete report will be distributed around the end of 2011 / beginning of 2012.

The agenda was adopted unchanged. The following documents were added during the meeting:
IGPG-03-10: (Bayer) Car Wash Round Robin Test
IGPG-03-11: (Bayer) Taber Round Robin Test Analysis
IGPG-03-12: (Bayer) PC Cutting Trails done by German Fire and Rescue Service (initiated by VDA)
IGPG-03-13: (MPA NRW) Round Robin sand drop test: Results and analysis
IGPG-03-14: (BASt) Comparative Tests with Laminated Safety Glass Panes and Polycarbonate
