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 Safety Standard ANSI/SAE Z26.1 or other applicable standards. The test applies to all installation locations.
Every five years each SAE Surface Vehicle Recommended Practice should be reviewed by members of the Glazing Committee. This will ensure both current relevance of the practice and consistency with other practices. Once reviewed and endorsed by the Committee it will be updated and reissued as a current practice.
