Rain - EN 343:2019

Clothing to protect against rain

This standard specifies the requirements and testing methods for clothing to protect against inclement weather (precipitation such as rain or snow), fog and ground-level moisture and the seams of such clothing.

Protection against rain is measured in two ways: resistance to water penetration and evaporative resistance.

The icon must be accompanied by the relevant performance levels:

• Water vapour resistance classification: Class 1 to 4 (Class 4 being the highest)
• Water penetration resistance classification: Class 1 to 4 (Class 4 being the highest)
• Rain tower test result (optional)

By combining high water penetration resistance with low water vapour resistance, body temperature and humidity can be better controlled, resulting in increased comfort.
