BS EN 343:2019 pdf free.Protective clothing – Protection against rain.
This document specifies requirements and test methods for the performance of materials and ready- made garments for protection against the effects of precipitation (e.g. rain, snowflakes), fog and ground humidity. Garments for protection against other effects than precipitation (e.g. water splashes, waves) are excluded from this standard. The protective effects and requirements of footwear, gloves and separate headwear are excluded from the scope of this document.

3.1 water vapour resistance water-vapour pressure difference between the two faces of a material divided by the resultant evaporative heat flux per unit area in the direction of the gradient
Note 1 to entry: It is a quantity specific to textile materials or composites, which determines the iatent evaporative heat flux across a given area in response to a steady applied water-vapour pressure gradient. The evaporative heat flux can consist of both diffusive and convective components.
Note 2 to entry: The water-vapour resistance is expressed in square metres pascal per watt.
