NFPA 70E Cat 2 FR Fabric: Built for Durability (9.1 cal/cm²)
Unlike lighter alternatives, this NFPA 70E Cat 2 FR fabric features a mid-weight 260gsm twill construction. This provides enhanced mechanical strength for coveralls and jackets while maintaining a soft hand feel.
Tested by Aitex (Report No. 2025CN0637) under the EN IEC 61482-1-1:2019 (Method A) standard. This “Open Arc” test method is technically comparable to ASTM F1959, validating the ATPV 9.1 cal/cm² result. This allows the fabric to be confidently used for compliance, offering a solid safety margin above the 8.0 cal/cm² threshold.
FAQ: NFPA 70E Compliance & Fabric Durability
Q1: Is an ATPV of 9.1 cal/cm² sufficient for my workers?
A: Yes. For most industrial electrical maintenance tasks, the safety requirement is PPE Category 2, which demands a minimum of 8 cal/cm². With a rating of 9.1 cal/cm², this fabric provides a solid safety margin above the standard requirement while remaining breathable and comfortable.
Q2: When should I choose 260gsm (FRCOA260) over 220gsm?
A: Choose the 260gsm (FRCOA260) when you need higher physical durability. While 220gsm is ultra-light for hot climates, 260gsm is the industry standard for jackets and trousers that need to withstand daily wear and tear in mechanical environments (like welding or construction sites) while still offering Arc Flash protection.
Q3: Does the 2% antistatic fiber affect comfort?
A: No. The 2% carbon fiber is woven into the fabric specifically to prevent static buildup (spark hazards) without compromising the softness or breathability of the 98% cotton base.
Q4: My project requires NFPA 70E. Can I use this IEC 61482-1-1 certificate?
A: Yes. The EN IEC 61482-1-1 (Method A) test is physically identical to the American ASTM F1959 Open Arc test. Both generate an ATPV rating. Our result of 9.1 cal/cm² meets and exceeds the 8.0 cal/cm² requirement for NFPA 70E Category 2 (Cat 2).
