EN 343 Guides

What Is EN 343?

EN343 is the European standard that applies to garments worn in adverse weather conditions. This standard specifies requirements and test methods applicable to the materials and seams of protective clothing against the influence of precipitation (e.g. rain, snowflakes), fog, and ground humidity.

What Is EN 343? - Pictogram Explanation

The pictogram to the left indicates that protection against rain is offered.

The standard provides for two performance parameters of which there are 4 levels with Class 4 offering the highest level of protection.

  • X - Water Penetration Resistance (Waterproofness) 4 Levels
  • Y - Water Vapour Resistance (Breathability) 4 Levels
  • R - Readymade Garment; Rain Tower Test (optional)
    R may be replaced by an X if the test has not been carried out or is not suitable.
