What design standard should be inspected on vehicle glass?

The correct answer focuses on the design standard known as AS, which stands for Automotive Safety. This standard is crucial for ensuring that the vehicle glass used in automobiles, such as windshields and windows, meets the necessary safety and durability requirements, providing protection to occupants and ensuring clear visibility.

The AS standard takes into account various factors including impact resistance, optical clarity, and the ability to withstand different environmental conditions without degrading. It plays a critical role in reducing the risk of injury in the event of an accident, as well as maintaining driver visibility under diverse weather conditions.

In contrast, the other options refer to non-standard identifiers that do not specifically correspond to recognized safety standards for vehicle glass used in automotive manufacturing and performance. Therefore, they would not provide the necessary assurance of quality and safety that the AS standard ensures for automotive glass.
