EN 343 / EN ISO 24232
​​​​​​​rain

Certified and approved garments provide protection against rain and inclement weather.

Requirements and test methods for fabrics and seams of protective clothing against the influence of rain, snow, fog and ground humidity. Resistance to water penetration (A) and water vapour resistance (B) is measured.

A: Resistance to water penetration: 1-4, where class 4 provides the best waterproofness
B: Breathability – water vapour resistance: 1-4, where class 4 provides the best breathability
C: Impact from above with high energy droplets (optional)

EN 343 was replaced in 2025 by EN ISO 24232. The new standard has the same content, pictogram and classes, so there is no difference in the level of protection provided by the garment. For garments certified to EN 343, the certification remains valid for the entire duration of the certificate. When the certificate is updated, it will be converted to the new standard EN ISO 24232.
