In hazardous industries, selecting the right flame-resistant (FR) garment is critical for worker safety and compliance. Two important European standards—EN ISO 14116 Index 3 and EN ISO 11612—define different levels of flame protection. Understanding how they differ and how they complement each other helps companies choose the most suitable FR and IFR garments for their workforce.
EN ISO 14116 specifies the performance of fabrics with limited flame spread. It uses three performance indices, with Index 3 offering the highest protection.
Index 1: Basic protection; fabric must not contact the skin directly.
Index 2: Better resistance but still requires layered use.
Index 3: Highest protection—no flame spread, no melting, and safe to wear directly against the skin.
Garments certified to Index 3 are often used as base layers or undergarments, providing an essential first layer of defense.
EN ISO 11612 is the European benchmark for protective clothing against heat and flame. It covers a wide range of hazards, including:
Convective heat (C)
Radiant heat (R)
Molten metal splashes (E, F)
Contact heat (B)
This standard applies to outer layers such as coveralls, jackets, and trousers, offering comprehensive protection in high-risk environments like oil & gas, welding, petrochemical, and utilities.
EN ISO 14116 Index 3 garments are ideal as base layers worn close to the skin.
EN ISO 11612 garments are designed as outer layers, protecting against a wider range of heat and flame hazards.
When combined, workers benefit from a layered PPE system that ensures maximum protection without compromising comfort.
FR workwear: Flame-resistant finishes can achieve compliance but may lose effectiveness over time.
IFR workwear: Inherently flame-resistant fibers maintain compliance for the lifetime of the garment, making them a preferred choice for long-term industrial safety.
At DOMEX SAFETY, we manufacture FR and IFR garments certified to EN ISO 14116 Index 3 and EN ISO 11612, including:
Coveralls, jackets, shirts, and trousers for outer protection
Base layer garments for full-body flame spread resistance
Multi-standard PPE also compliant with NFPA 2112, ASTM F1506, EN 1149, and IEC 61482
Our clothing provides durable, comfortable, and globally compliant protection for industrial workers.
EN ISO 14116 Index 3 and EN ISO 11612 serve different but complementary roles in industrial PPE. Index 3 ensures close-to-skin flame resistance, while EN ISO 11612 provides outer-layer protection against multiple heat hazards. Together, they create a reliable safety system for workers in high-risk environments.
