J2568_202508 Intrusion Resistance of Safety Glazing Systems for Road Vehicles

This SAE Recommended Practice specifies an intrusion resistance test method for glazing systems installed in motor vehicles.

Intrusion resistance performance is determined not solely by the glazing but also by the glazing attachment to the vehicle and by the vehicle structure. Therefore, the glazing/attachment/vehicle structure must be tested as a single unit.

This test determines intrusion resistance only. The test applies to those materials that meet the requirements for use as safety glazing materials as specified in ANSI/SAE Z26.1 or other applicable standards. The test applies to all installation locations.
