What is AS1 used for in vehicle glass?

AS1 is a designation used for specific types of automotive glass, primarily associated with windshields. It refers to the standard of safety and performance for the glass used in the front windshield of a vehicle. This designation indicates that the glass meets particular criteria for impact resistance, visibility, and other crucial safety standards. In general, the AS1 symbol is found on windshields, confirming that they conform to regulations for safety in the event of an accident.

Windshields serve multiple functions, including structural support to the vehicle's roof, protection for passengers from external elements, and, in many cases, the accommodation of sensors and cameras for advanced driver assistance systems. Thus, the glass used in these applications, denoted as AS1, is vital for ensuring both safety and compliance with Maryland's inspection standards.

The other choices reference various types of vehicle glass, which may have different standards and specifications but do not apply to the AS1 designation.
