Understanding Key FR Workwear Standards: A Quick Comparison Guide
[
30.05.2026]When selecting flame-resistant (FR) workwear and FR base layers, understanding the relevant certifications is essential. Different industries and regions may require different standards depending on the hazards involved.
The table below provides a quick overview of the most commonly requested FR standards.
|
Standard |
Region |
Protection Type |
Typical Industry |
Key Requirement |
|---|---|---|---|---|
|
EN ISO 11612 |
Europe |
Heat & Flame Protection |
Oil & Gas, Utilities, Manufacturing |

Why These Standards Matter
A complete FR clothing system often requires multiple certifications rather than a single standard.
For example:
|
Work Environment |
Recommended Standards |
|---|---|
|
Oil & Gas |
EN ISO 11612 + EN 1149-5 |
|
Electrical Utility |
IEC 61482-2 + EN ISO 11612 |
|
Petrochemical Plant |
EN ISO 11612 + EN 1149-5 + NFPA 2112 |
|
Arc Flash Risk Areas |
IEC 61482-2 or NFPA 70E |
The Importance of FR Base Layers
Many end users focus on the outer garment, but the base layer is also a critical component of the PPE system.
A certified FR base layer can:
-
Enhance overall thermal protection
-
Reduce the risk of burn injury
-
Improve moisture management and comfort
-
Support compliance with arc flash and flame protection requirements
At Keensun, we develop FR base layer fabrics and garments designed to meet the requirements of international protective clothing standards while maintaining comfort for long working shifts.
