EN 343 – Certified workear for protection from rain

Protective clothing certified according to EN 343 protect against precipitation as rain or snow, fog and ground humidity. The garment and the seams are tested for its water resistance, but also water vapour resistivity. The garment is classified according to water resistant properties, and the water vapour resistivity gives the recommended working time.

A = Class waterpenetration (max 3)
B = Class water vapour resistance (max 3)

Water penetration resistance Class
1 2 3
Test on fabric ? 8 000 Pa, before pre-treatment ? 8 000 Pa , after pre-treatment ? 13 000 Pa, after pre-treatment
Tests on seam, before pre-treatment ? 8 000 Pa ? 8 000 Pa ? 13 000 Pa

1 mVc (meter water column) = 10 000 Pa

 

The preferred working hours based on the garment’s water vapour resistivity Class
Operating temp, °C 1 2 3

20 75 250
15 100
10 240
