2.Introduction
In this European
Standard 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 to be 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 new and
pretreated fabric samples and on parts with seams.
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).

3-1 Scope
This European Standard
specifies requirements and test methods applicable to materials and seams of
protective clothing
against the influence of precipitation (e. g. rain, snowflakes), fog and ground
humidity.
The testing of rain
proofness of ready made garments is excluded in this standard at this time
because a
separate test method for
such a property is currently being prepared.
3-2 Normative references
This European Standard
incorporates by dated or undated reference, provisions from other publications.
These
normative references are
cited at the appropriate places in the text and the publications are listed
hereafter. For
dated references,
subsequent amendments to or revisions of any of these publications apply to this
European
Standard only when
