EN 343
​​​​​​​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)

The EN 343 norm was updated during 2019 with the addition of class 4 (previously class 1-3). Fristads waterproof garments released during 2020 have been tested according to the new version of EN 343.
An ongoing update and recertification of existing garments is underway.
