Which standard would not apply to a sample for hot-rolled steel shapes?

To determine why the option related to ASTM A53 does not apply to a sample for hot-rolled steel shapes, it's essential to understand the specific focus of each standard.

ASTM A36 is a standard specification for carbon structural steel shapes, plates, and bars used in general construction and structural applications. Therefore, this standard is applicable to hot-rolled steel shapes.

ASTM A992 provides specifications for structural steel shapes used in building framing. It is specifically tailored for use in steel construction and is closely associated with hot-rolled shapes. Thus, this standard is also relevant.

ASTM A325 pertains to the specifications for high-strength bolting for use in structural steel joints. While it plays a critical role in the connections and assembly of hot-rolled steel shapes, it does not govern the shapes themselves directly.

In contrast, ASTM A53 focuses on seamless and welded steel pipes and does not cover hot-rolled steel shapes. It is primarily concerned with pipe specifications rather than structural shapes. Therefore, this standard is the one that does not apply in the context provided.
