Intrusion Resistance Test Development for Automotive Glazing 1999-01-3159

Consumers worldwide are demanding intrusion resistant automotive glazing. In response, carmakers are installing laminated side and rear glazing for enhanced protection. To insure enhanced protective glass (EPG) performance, a test is being developed to measure intrusion resistance in three simulated break-in modes.
The three test modes are: glazing point attack; exterior impacts to penetrate the glazing or separate it from the vehicle body; continuous force to pull the glazing out of the body.
The strength of the glazing and the strength of the glazing/vehicle attachment are both important for intrusion resistance.
An intrusion resistance test method is recommended.
