Introduction
In this document the measured properties of materials and seams of protective clothing and their
subsequent classification are intended to ensure an adequate protection level. Water proofness and
water vapour resistance are the essential properties tested and marked on the label.
Water proofness is the most important property and it is measured on material of the outer garment
layer. Tests are made on pretreated fabric samples and on parts with seams.
A test method for an optional readymade garment test after cleaning is described (rain tower test).
Some waterproof materials are impermeable to water vapour transmission. However other materials
on the market combine water proofness with water vapour permeability. This property expressed by
low water vapour resistance enhances sweat evaporation and significantly contribute to body cooling.
This is valuable, because it contributes to better comfort and less physiological strain and prolongs the
wearing time in certain climatic conditions (see Annex A).

1 Scope
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.
