Which are examples of consensus standards? (select one)

• A. NFPA, NEC, NESC, ANSI
• B. OSHA standards
• C. Proprietary company standards
• D. Local ordinances

Answer: (A)

Consensus standards are open, voluntary guidelines created through a formal process that includes input from a broad set of stakeholders—manufacturers, users, inspectors, and regulators—along with public review and balanced representation. This collaborative, due-process approach sits behind the credibility and broad adoption of such standards. Organizations like NFPA develop widely used standards such as the National Electrical Code, which is a quintessential consensus standard because it arises from a collaborative effort and is updated through a transparent process. The National Electrical Safety Code (NESC) also embodies this approach, with the development process that involves recognized bodies and adherence to ANSI/IEEE procedures. ANSI plays a crucial role as the accrediting body ensuring that standards are produced through open, balanced consensus.

These standards are typically voluntary guidelines that become mandatory only if adopted into law, contract, or regulation. In contrast, OSHA standards are regulatory requirements issued by the government, not products of a consensus development process. Proprietary company standards are internal guidelines specific to one organization, and local ordinances are laws enacted by municipalities. Therefore, the examples that illustrate consensus standards here are NFPA, the NEC, NESC, and ANSI.
