Which are examples of consensus standards?

• A. NFPA
• B. NEC
• C. NESC
• D. NFPA, NEC, NESC, ANSI

Answer: (D)

Consensus standards come from open, balanced processes where a broad group of stakeholders contributes and votes to approve the content. National Fire Protection Association standards are built this way, with committees that include manufacturers, users, regulators, and other interested parties, and they go through formal public input and voting. The National Electrical Code is part of that family, published by the same organization and developed through the same broad, participatory process. The National Electrical Safety Code follows a similar pathway, developed by IEEE with ANSI endorsement, again through open review and voting. ANSI itself is the accrediting body that ensures these standards come from a transparent, consensus-based process. So NFPA standards, the NEC, the NESC, and ANSI all illustrate consensus standards.
