Which of the following is NOT listed as a recognized source of standards used by the commissioner?

• A. Local building codes
• B. Federal law or regulation adopted standards
• C. Standards published by a nationally recognized standards-making organization
• D. Standards developed by individual manufacturers

Answer: (A)

The key idea is understanding what counts as an official standard in regulatory practice. The commissioner relies on standards that carry broad, formal recognition: federal law or regulation adopted standards; standards published by nationally recognized standards‑making organizations; and standards developed by individual manufacturers when they are adopted or referenced in regulations or listings. Local building codes, while important for a specific locality, are created by local authorities and can vary from place to place; they’re not the universal, nationally recognized sources the commissioner typically relies on. So local building codes are not listed as recognized sources of standards in this context.
