Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not

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 pre-treated fabric samples and on parts with seams. A test method for an
optional readymade garment test after cleaning is described (rain tower test).
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).

Protective clothing — Protection against rain
1 Scope
This document specifies requirements and test methods for the performance of materials and
readymade 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 document. The protective effects and requirements of footwear, gloves
and separate headwear are excluded from the scope of this document.

3.1
water vapour resistance
R
et
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 “latent”
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.

3.2
resistance to water penetration
WP
hydrostatic pressure supported by a material as a measure of the opposition to the passage of water
through material
Note 1 to entry: WP is expressed in pascal.

4 Performance assessment and requirements
4.1 General requirements and innocuousness
4.1.1 General requirements
All the individual results of the specimens of a test shall meet the performance requirement.If a
material exhibits differing behaviour for a property in the length and cross directions of the material,
the resultant property value shall be the value obtained in the lesser performing direction.In the event
that only one specimen fails, another set of specimens shall be tested and all the individual results of
this second set of specimens shall meet the requirements. Otherwise, the sample is considered to have
failed the requirement.
When tested in accordance with 5.2.1 the requirements according to ISO 13668:2013 and
ISO 13688:2013/Amd1: 2021, 4.3.1, 4.3.2, 4.4.1 and the following requirements shall be met:
— all pockets shall be constructed to avoid water penetration inside the garment;
— closures, such as slide fasteners, fasteners, buttons etc. shall not open inadvertently.
If the protective clothing claims to have other protective properties, it shall also meet applicable
requirements in relevant product standards.
For material testing the application of the single tests to each component is
