EN343 Waterproof Rating Raincoat Supplier | Certified Workwear, Safety Gear & Custom Manufacturing
Why EN343 Raincoats Matter in Today's Market
What Makes EN343 Different From Regular Waterproof Ratings?
EN343 isn’t just another waterproof rating – it’s a comprehensive European standard that addresses both waterproofing and breathability, making it the gold standard for professional workwear. Unlike simple hydrostatic head measurements, EN343 certification ensures that rainwear performs reliably in real-world industrial conditions.
Key Differentiation Factors
- Double Certification: Tests both waterproofing AND breathability
- Industrial Grade: Designed for heavy-duty professional use
- European Compliance: Meets EU PPE regulation requirements
- Multi-Class System: Allows buyers to choose appropriate protection levels
Understanding EN343 Waterproof Ratings
What Is EN343?
EN343 is a European standard that specifies requirements for protective clothing against foul weather. Published by CEN (European Committee for Standardization), this standard has become the benchmark for waterproof and breathable workwear in Europe and increasingly worldwide.
The Two Key Requirements: Waterproofing & Breathability
EN343 uniquely combines two critical performance aspects that traditional ratings often treat separately:
Waterproof Performance (Class 1-3)
Tests resistance to water penetration under pressure, ensuring protection against heavy rain and extended exposure.
Breathability Performance (Class 1-3)
Measures moisture vapor transmission rate, preventing heat stress and maintaining wearer comfort during extended use.
The Meaning of Class 1, Class 2, and Class 3 Ratings
EN343 uses a sophisticated classification system that allows buyers to select appropriate protection levels for their specific applications:
| Class Level | Waterproofing (mm) | Breathability (g/m²/24h) | Typical Applications |
|---|---|---|---|
| Class 1 | 800+ mm | 1,000+ g/m² | Light rain, short exposure |
| Class 2 | 1,300+ mm | 2,000+ g/m² | Moderate rain, extended wear |
| Class 3 | 2,000+ mm | 3,000+ g/m² | Heavy rain, professional use |
EN343 vs. Other Ratings (e.g., HH, WP, Hydrostatic Head)
Understanding how EN343 compares to other waterproof ratings helps buyers make informed decisions:
Hydrostatic Head
Measures only waterproofing pressure. No breathability assessment.
WP (Waterproof)
Varies by manufacturer. No standardized testing protocol.
EN343
Standardized European testing. Both waterproofing AND breathability certified.
Why Businesses Need EN343-Certified Rainwear
Compliance With European PPE Regulations
For companies operating in Europe or serving European markets, EN343 certification isn’t optional – it’s a legal requirement for personal protective equipment. The PPE Regulation (EU) 2016/425 mandates that protective clothing meets specific performance standards, and EN343 provides the framework for weather protection.
⚠️ Regulatory Requirements
- Mandatory for PPE suppliers in EU market
- Required for government and public sector procurement
- Essential for ISO 9001 certified organizations
- Critical for insurance and liability protection
Worker Safety in Harsh Weather
Non-certified rainwear creates genuine safety risks for outdoor workers. Inadequate waterproofing leads to wet clothing, while poor breathability causes overheating and heat stress – both serious workplace hazards.
Liability Protection for Employers
Using certified EN343 rainwear demonstrates due diligence in worker protection. In case of weather-related incidents, certified equipment provides legal protection and reduces liability exposure.
Why Buyers Prefer Certified Gear
Professional buyers consistently choose EN343-certified products because they offer:
- Predictable Performance: Certified products perform consistently across batches
- Reduced Risk: Lower failure rates and warranty claims
- Procurement Efficiency: Standardized specifications simplify purchasing
- Brand Protection: Quality standards protect brand reputation
