Cigarette Smolder Standard

Direct Answer Summary

CPSC 16 CFR Part 1632 is the federal flammability standard governing cigarette ignition resistance of mattresses and mattress pads. The test places lighted standard reference cigarettes on the bare mattress surface, between tufts, and along tape edges, both with and without bed sheets. To pass, the resulting char length on the mattress surface must not exceed 2.0 inches in any direction, and no progressive smoldering may develop.

Audited Core Takeaways

  • 1Mandates that char length must not exceed 2.0 inches in any direction from a burning cigarette.
  • 2Tests multiple surface configurations: bare ticking, sheeted, quilt crevices, and tape edges.
  • 3Operates as a companion standard alongside CPSC 16 CFR Part 1633 open flame testing.

Uniform Law Label & Material Deconstruction

Under FTC 16 CFR Part 303 and IABFLO uniform law label standards, bedding manufacturers must disclose exact net filling weights using standardized generic fiber terms. Marketing buzzwords are prohibited under federal penalty.

Safety Inspection Protocol3 Actionable Steps

Consumer Safety & Chemical Verification Protocol

Step-by-step physical inspection procedure for flame barrier integrity and law label compliance.

Verify Law Tag Compliance

Step 1

Confirm the law tag cites compliance with 16 CFR Part 1632 and 16 CFR Part 1633.

Critical Hazard to Avoid

Never buy mattresses citing only Part 1632; modern federal law requires both.

Inspect Surface Rosettes

Step 2

Examine button tufting or rosettes to verify dense, non-combustible thread construction.

Critical Hazard to Avoid

Do not smoke in bed or leave unattended hot irons or electric heating pads.

Check Protective Mattress Pads

Step 3

Ensure any topper or pad added also complies with 16 CFR Part 1632.

Critical Hazard to Avoid

Avoid cheap untreated synthetic fleece toppers that easily ignite.
