Intrusion Resistance Test Development for Automotive Glazing

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.
