When sourcing flame-resistant (FR) and inherently flame-resistant (IFR) garments, buyers often come across EN ISO 14116 Index 3 certification. This standard is a key indicator of safety in industrial personal protective equipment (PPE). Understanding the testing process behind Index 3 helps buyers ensure they are investing in garments that meet the highest flame spread protection requirements.
EN ISO 14116 is a European standard for limited flame spread protection. It classifies fabrics into three levels (Index 1, 2, and 3), with Index 3 offering the highest performance. Garments meeting Index 3 can be worn directly against the skin and provide superior resistance to flames without melting, dripping, or afterglow.
To achieve Index 3 certification, fabrics must pass strict laboratory testing:
Flame Spread Test – Material is exposed to a flame for a set duration to measure ignition resistance.
No Melting or Dripping – The fabric must not melt or drip when exposed to flame.
Afterflame & Afterglow Limits – The material must self-extinguish quickly and not continue to glow after testing.
Durability Verification – Testing is conducted after specified laundering cycles to confirm long-term performance.
These requirements ensure that garments certified to EN ISO 14116 Index 3 deliver consistent protection in real industrial conditions.
1. Worker Safety – Index 3 certified garments provide reliable protection for workers in oil & gas, petrochemical, utilities, and welding industries.
2. Compliance – Meeting international testing standards ensures legal and regulatory compliance across Europe and globally.
3. Confidence in Quality – Buyers can trust that FR and IFR workwear certified to Index 3 have passed rigorous testing and will perform in hazardous environments.
FR Garments: Fabrics treated with flame-resistant finishes can meet Index 3 standards but may require careful maintenance.
IFR Garments: Inherently flame-resistant fabrics maintain Index 3 performance for the entire lifetime of the garment, making them highly reliable.
