Large engineering firms and academic institutions utilize authorized multi-user platforms like IHS Markit (S&P Global), Techstreet, or ANSI. These platforms provide cloud-based access to the most up-to-date versions of Section II, automatically integrating errata and code cases.

The section is divided into four distinct parts, each serving a specific engineering purpose:

Part C is critical for ensuring the strength and integrity of welded joints. It provides specifications for the manufacture, chemical composition, mechanical usability, testing, and operating characteristics of welding consumables. These specifications are derived from AWS (American Welding Society) standards and use "SFA" numbers.
