RAIN

PROTECTION

US427
WATER RESISTANCE AND

BREATHABILITY TESTING
We cannot control the weather, and when it rains
you need clothing that protects you as you work.
EN343 protection against rain sets out the
requirements for clothing, materials and seams to
protect against rain, and also snowflakes, fog and
ground humidity.

The standard uses 2 performance parameters:
water resistance and breathability. There is an
optional rain tower test (EN 14360) where clothing
is exposed to the impact of high energy droplets
(450liters/m²/hr).
The performance is shown as e.g., EN343 Class
4:3:X, where 4 is the water resistance, 3 the
breathability and X indicates the optional rain
tower test was not undertaken.
