This SAE Recommended Practice is intended to cover current safety glazing practice applicable to safety glasses for use in motor vehicles and motor vehicle equipment. Nominal specifications for thickness, flatness, curvature, size, and fabrication details are included principally for the guidance of body engineers and designers. For additional information on safety glazing materials for use in motor vehicles and motor vehicle equipment, see SAE J674.The function of uniform terminology is to promote understandable and exact communication. A great deal of effort has been expended to make these definitions suit this purpose. It is recognized that this terminology, like other dictionaries, must be revised perlodically to reflect current usage and changing needs. The Vehicle Dynamics Committee therefore solicits suggestions for improvements and additions to be considered in future revisions. Comments should be directed to SAE Headquarters.
