Wood shingles are rated by which standard?

Wood shingles are rated by which standard?

• A. NFPA 101
• B. NFPA 256
• C. NFPA 70
• D. NFPA 80

Answer: (B)

Testing roof coverings for fire performance is the focus here. NFPA 256 provides the standard method for fire testing roof coverings, including wood shingles, to evaluate how they behave under fire exposure and what fire rating they carry. This rating helps codes determine whether the material is acceptable for use on a roof and how it affects overall fire safety of the building. The other standards address different areas: NFPA 101 covers life safety, NFPA 70 is the electrical code, and NFPA 80 deals with fire doors and fire-rated openings, none of which govern how roof coverings like wood shingles are tested and rated.
