For gym owners, daycare facility managers, and construction contractors, the “Fire Inspection” day is often the most stressful part of a project.
Failing a fire code inspection because of non-compliant flooring means delays, ripped-up floors, and thousands of dollars in wasted material.
At Suzhou HRED Mat Co., Ltd., we believe safety shouldn’t be a guessing game. We are proud to announce that our latest batch of Fire Retardant EVA Foam Mats has been officially certified as NFPA 101 Class I by SGS, meeting the strictest US safety codes.
What is ASTM E648 and Why Do You Need It?
If you are buying flooring for a public space in the USA (or projects following US standards), your Fire Marshal will likely ask: “Does this flooring meet ASTM E648?”
ASTM E648 tests the “Critical Radiant Flux” of a floor. In simple terms, it measures how much heat energy is required to keep the floor burning. The higher the number, the harder it is to burn.
Class II (0.22 W/cm²): acceptable for some areas.
Class I (0.45 W/cm²): Required for exit corridors, hospitals, and high-occupancy areas. This is the gold standard.
Our Test Results: 2.4x Safer Than the Requirement
Many suppliers barely scrape by with a “Pass.” We aim higher.
According to our SGS Test Report (No. AJFS2412015248FF), dated December 27, 2024, our EVA Mats performed exceptionally well.
| Performance Metric | US Class I Requirement | HRED Mat Result |
| Critical Radiant Flux | ≥ 0.45 W/cm² | 1.09 W/cm² 🚀 |
The Verdict: Our mats scored 1.09 W/cm².
This is more than double the safety requirement for Class I flooring. This massive safety margin proves that our high-density EVA foam is incredibly resistant to fire spread, giving you peace of mind and ensuring a smooth inspection process.
Why "High Density" EVA Makes the Difference
How did we achieve such a high score? It comes down to material quality.
The tested sample features a density of 1.9 kg/m ² (approx. 21.3mm thickness).Cheap, low-density foam acts like fuel for a fire. Our high-density EVA is engineered to resist ignition. This density also provides:
Better Durability: Won’t sink or deform under heavy gym equipment.
Superior Grip: The “Grain Surface” (tested) offers excellent slip resistance.
Long-Term Value: A mat that lasts longer and protects better.
Ideal Applications for Class I EVA Mats
Because our product meets NFPA 101 Class I, it is suitable for the most strictly regulated environments:
School Gymnasiums & Hallways
Martial Arts & MMA Studios
Daycare Centers & Indoor Playgrounds
Healthcare Facility Activity Areas
Conclusion
Not all foam is created equal. When you choose Suzhou Hengruida, you aren’t just buying a mat; you are investing in certified safety. Our fire retardant foam padding combines premium impact absorption with verified fire resistance that goes far beyond the minimum requirements.
