Which standard must interior floor covering materials comply with in all occupancies?

The requirement for interior floor covering materials to comply with specific standards is essential for safety and performance in all types of occupancies. The correct answer indicates that compliance with either the DOC FF-1 "pill test" or ASTM D 2859 is acceptable for these materials.

The DOC FF-1 “pill test” is a standard developed by the Consumer Product Safety Commission which assesses the flammability of floor coverings. This standard is crucial because it helps to ensure that the materials used within a space do not contribute to the spread of fire, which is a significant safety concern across all types of buildings.

Similarly, ASTM D 2859 is a standard test method that evaluates the flammability characteristics of floor covering materials. It complements the DOC FF-1 test by providing another avenue for assessing the fire performance of flooring materials.

By allowing for compliance with either of these established standards, the correct answer highlights the importance of ensuring that all interior floor coverings, regardless of the building type, meet recognized safety criteria to minimize fire hazards. This dual compliance option provides flexibility for manufacturers and builders while maintaining necessary safety levels across diverse occupancy types.
