Which NFPA Standard deals with Fire Test for Flame Propagation of Textiles and Films?

• A. 70
• B. 80
• C. 701
• D. 101

Answer: (C)

Testing flame propagation of textiles and films relies on a standardized method so results are consistent and defensible in code compliance. NFPA 701 provides the official test methods and criteria for determining how textiles and films behave when exposed to flame, including how flame propagates across or through the material and the pass/fail thresholds. This standard is used to assess fabrics and films used in upholstery, drapery, clothing, theater, and architectural finishes, ensuring they meet minimum flame-resistance requirements required by codes and labeling.

NFPA 70 covers electrical installations, not flame propagation of textiles. NFPA 80 deals with fire doors and fire windows, focusing on door and window assemblies rather than textile materials. NFPA 101, the Life Safety Code, governs overall life-safety requirements in buildings but does not prescribe the specific textile flame-propagation test methods.
