Parts of documents that contain required standards are called?

• A. Informational sections
• B. Mandatory sections
• C. Water mist fire protection
• D. Extracted text

Answer: (B)

In NFPA standards, content is divided into sections that state what must be done and sections that provide guidance. The parts that contain the required standards are called mandatory sections. These sections use enforceable language (often “shall”) to indicate the requirements designers, installers, and authorities having jurisdiction must follow. Informational sections, by contrast, offer explanations, examples, or commentary and aren’t enforceable requirements. The other options don’t fit because they refer to guidance or unrelated topics rather than the enforceable parts of the standard.
