Draperies used in public spaces must pass the NFPA 701 standard, which specifically addresses the flammability of textiles and related products. This standard provides a test method to determine the burning characteristics of drapery materials. Compliance with NFPA 701 is essential in preventing the risk of fire spread in public areas, where large groups of people may be present and where strict safety regulations are enforced.

The other standards mentioned, while important in their respective contexts, do not specifically pertain to drapery materials in the same way that NFPA 701 does. For instance, NFPA 260 covers the flammability of upholstered furniture, UL 1715 pertains to the fire test of fire-resistance-rated doors and shutters, and ASTM E648 focuses on the critical radiant flux of floor coverings. Each of these standards serves different materials and applications, but for draperies specifically, NFPA 701 is the relevant standard to ensure compliance in public spaces.
