ASTM E84 Class A Cert — Printed Acoustical Panels

ASTM E84 Class A surface burning characteristics certification for OrangePiel printed acoustical panels — Flame Spread Index ≤ 25 and Smoke Developed Index ≤ 450, the IBC Chapter 8 commercial-occupancy fire-rating requirement. Signed lab cert PDF. At a glance — Class A, Flame Spread Index ≤ 25, Smoke Developed Index ≤ 450 per ASTM E84 Standard Test Method for Surface Burning Characteristics of Building Materials. Test method: Steiner Tunnel apparatus, 10-minute burn cycle. Test panel configuration: face fabric over absorptive core, mounted as installed. Lab: independent NVLAP-accredited fire-testing laboratory. Class A is the most stringent rating under ASTM E84 — required by the International Building Code (IBC) Chapter 8 for interior wall and ceiling finishes in most commercial occupancies. Coverage: IBC Group A Assembly (restaurants, theaters, places of worship, conference venues), Group B Business (offices, professional services, banks), Group E Educational (K-12, daycare, vocational schools), Group I Institutional (hospitals, clinics, senior living, behavioral-health), Group R-1 Residential transient (hotels, motels, short-term lodging), Group M Mercantile (retail, showrooms, exhibition halls). Companion fabric flame propagation rating: NFPA 701 (2023 ed.) compliant under both small-scale Test Method 1 and large-scale Test Method 2. Many hospitality, healthcare, and assembly occupancies require both ASTM E84 (panel assembly) AND NFPA 701 (textile face) — OrangePiel printed acoustic panels carry both ratings on the same product.
