Outdoor industrial work often exposes employees to rain, wind, and harsh weather conditions. Ensuring their safety and comfort requires workwear certified to EN 343 Class 3:1 X, the international standard for waterproof and weather-resistant clothing. Understanding this standard helps companies choose FR and IFR garments that provide both hazard protection and weather resilience.
EN 343 is the European standard for protective clothing against rain and adverse weather. The classification system uses three elements:
Class 3: Highest waterproof rating – fabric can withstand prolonged exposure to heavy rain.
Class 1: Breathability rating – ensures comfort by allowing moisture vapor to escape, preventing overheating.
X: Additional performance feature, such as seam strength or resistance to water penetration at seams.
Garments certified to EN 343 Class 3:1 X offer a balance of maximum water protection and comfort, suitable for industrial workers exposed to wet conditions.
1. Worker Safety and Comfort – Prevents rain-related discomfort and reduces risks of cold stress in outdoor environments.
2. Layering with FR/IFR Garments – Can be worn over EN ISO 11612 or EN ISO 14116 certified garments, ensuring dual protection against fire and weather.
3. Durability – High-performance materials resist wear and tear, maintaining waterproofing even after repeated use.
4. Compliance – Helps companies meet European safety regulations and international industrial PPE standards.
EN 343 Class 3:1 X workwear comes in various styles to suit industrial and outdoor applications:
Waterproof coveralls – Full-body protection for chemical or flame-resistant base layers
Rain jackets and coats – Lightweight, breathable, and ideal for layering over FR or IFR garments
Rain trousers – Overpants that protect legs from water exposure
Hooded jackets – Adjustable hoods enhance protection in heavy rain or wind
These garments are designed to be comfortable, flexible, and compatible with other PPE.
