A Review of Glazing Road Use Conditions and Laboratory Simulations

This paper addresses glazing road use conditions and presents the results of a research program which investigated laboratory simulations of road use A review of current testing requirements for glazing used in locations through which driver vision is required is presented to introduce the development of improved glazing performance factors.

The focus of this paper is the perceived need to insure the continuing use of realistic safety performance tests as new glazing technology emerges. This paper presents results of test simulations on glass, plastic, and glass-plastic materials using elements of a road use exposure model. Both sequential and non-sequential types of testing were evaluated.
