WHAT DOES THE EN 343 STANDARD INVOLVE?
The EN 343 standard promotes two high values: waterproofness and water vapour resistance, also called breathing capacity. In the icon of the EN 343 standard, these values are represented by an X-value and a Y-value, in which the X-value stands for the class of waterproofness and the Y-value stands for the class of water vapour resistance. The work garment for both waterproofness and breathing capacity is classified under one of the three classes within the EN 343 standard, if a work garment satisfies a certain minimum value. The class for the waterproofness and the class for breathing capacity are not interdependent. For example, a product could have a strong waterproofness (class 3) and at the same time have a less strong breathing capacity (class 1).
