Intertek-Verified Fire Safety: Class A Excellence for Critical Environments

Sinopan's PIR insulated panels deliver uncompromising fire safety, validated through rigorous third-party testing by Intertek under the ASTM E84-22 standard – North America's benchmark for surface burning characteristics. Our panels achieved the highest possible classification with exceptional results:

Certified Fire Performance Metrics:

🔥 Flame Spread Index (FSI): 0
*(Class A threshold: ≤25 | Perfect score = 0)*

☁️ Smoke Developed Index (SDI): 140
*(Class A threshold: ≤450 | Lower = Better)*

Why ASTM E84-22 Certification Matters:

✅ Highest Fire Classification: Meets and exceeds Class A requirements (FSI ≤25, SDI ≤450)

✅ Life Safety Priority: Limits flame propagation and toxic smoke in critical facilities

✅ Code Compliance: Accepted by IBC, NFPA 101, and FM Global for commercial/industrial projects

✅ Third-Party Trust: Intertek verification ensures unbiased, globally recognized data

Engineering Superiority Behind the Numbers:

FSI=0: Near-zero flame propagation – among industry's highest fire containment performance

Optimized Smoke Control: SDI 140 represents Class A's maximum allowable smoke density

Core Technology: Advanced PIR formulation with flame-retardant chemistry resisting 1000°C+ temperatures

FSI=0 isn't just a number – it's potentially life-saving containment. Combined with our managed smoke development, this gives designers confidence to specify Sinopan panels where safety can't be compromised.
