In high-risk industries, Personal Protective Equipment (PPE) must protect workers from hazards such as flames, heat, and static discharge. Among the global safety standards, EN ISO 14116 Index 3 plays a critical role in defining the flame-resistant (FR) performance of protective clothing. For companies selecting FR and IFR garments, understanding this standard ensures both safety and compliance.
EN ISO 14116 is the European standard for clothing with limited flame spread properties. The standard uses three indices (1, 2, and 3) to classify performance, with Index 3 providing the highest level of protection.
Index 1: Fabric may allow flame spread and should not contact the skin.
Index 2: Fabric resists flame spread better but still requires protective layering.
Index 3: The highest level, ensuring no flame spread, no melting, and no afterglow—making it suitable for garments worn directly against the skin.
1. Maximum Safety – Workers in oil & gas, welding, petrochemical, and utility industries face flash fire and heat hazards. Index 3 certified garments provide superior frontline protection.
2. Layering Compatibility – Index 3 fabrics can be safely used as base layers, complementing other FR and IFR garments certified to standards like EN ISO 11612 or NFPA 2112.
3. Worker Confidence – Wearing PPE certified to the highest flame spread index improves trust, compliance, and safety culture in hazardous environments.
FR Garments: Flame-resistant finishes applied to fabrics can achieve Index 3 performance, though durability depends on proper maintenance.
IFR Garments: Inherently flame-resistant fabrics retain their Index 3 protection throughout the garment's lifetime, offering long-term reliability.
At DOMEX SAFETY, we provide EN ISO 14116 Index 3 certified FR and IFR garments, including:
Coveralls, shirts, trousers, and jackets
Base layers and multi-standard PPE combining flame resistance, anti-static, and arc flash protection
Products also tested to EN ISO 11612, EN 1149, NFPA 2112, ASTM F1506, and IEC 61482
Our solutions ensure that workers remain protected, comfortable, and compliant in modern industrial workplaces.
EN ISO 14116 Index 3 sets the benchmark for flame spread protection in modern PPE. For industries where fire hazards are a daily risk, selecting Index 3 certified FR and IFR garments is essential for safeguarding workers and meeting global compliance standards.
