Protective clothing - Ensembles and garments for protection against cold
This document specifies requirements and test methods for the performance of clothing ensembles (i. e. two piece suits or coveralls) and of single garments for protection against the effects of cold environments (see Annex B). These effects comprise not only low air temperatures but also humidity and velocity of the air. Water penetration is not considered in this standard, but water can strongly affect the insulation of a garment. In the cases where influence of water can be expected, the garments should be assessed by EN 343.
The protective effects and requirements of footwear, gloves and separate head wear are excluded from the scope of this standard. For these effects the specific product standards apply.

Introduction
This document is published to achieve a common basis in Europe for requirements and test methods for
protective clothing ensembles and garments against cold in the interest of manufacturers, test institutes
and end-users. The measured properties and their subsequent classification are intended to ensure an
adequate protection level under different user conditions. Thermal insulation of the ensemble or
garment and the air permeability are the essential properties to be tested and marked on the label.
Thermal insulation is the most important property and it is measured by using a full-sized thermal
manikin with the ensemble or garment and accompanying standard clothing in order to account for the
effect of layers, fit, drape, coverage and shape.
In this respect this standard differs from many other standards specifying only material properties. The
insulation is tested with complete ensembles and garments after a defined pretreatment ensuring that
processing the garment considers mechanical aspects making tests like flexibility or abrasion
unnecessary. It should be recognized that ensembles and garments in frequent use can lose significant
insulation capacity due to laundering and wear. In general high quality products and well maintained
clothing are less affected in this respect.
Wind can considerably increase convective heat losses. Therefore, the air permeability of the outer
garment material is an important factor to be taken into account in relation to the protection of the
wearer against cold.
In cold conditions as defined by the standard the possible exposure to water is seldom and considered
to be limited, therefore this standard contains only optional requirements to water penetration. In case
the exposure to water is not limited, EN 343 applies.
can be used to assess temperature ranges according
The resultant effective thermal insulation value Icler
to Tables C.1 and C.2. This guidance information for the selection of the appropriate cold protective
garment(s) is one of the benefits, if the resultant effective thermal insulation value I of the garment(s)
cler
has been measured on a thermal manikin.
Sweating should be avoided in continuous cold exposure, since moisture absorption will progressively
reduce insulation. This is best controlled by selecting optimal rather than maximal insulation and
flexible, adjustable garments rather than fixed and closed ensembles. It is more efficient to get rid of
heat and moisture by ventilation of clothing through adjustable openings and button-up, than by
passive diffusion through layers of garments. In some conditions with intermittent exposures (e.g. cold
store work) or in conditions close to and above 0 °C the water vapour resistance value of fabrics
become increasingly important and fabrics with a low value can contribute to improved heat balance
and thermal comfort.

5 Pretreatment
The specimens used for the tests specified in 6.2 to 6.5 shall be pretreated by cleaning, which shall be in
line with the manufacturer’s instructions on the basis of standardized processes.
If the number of cleaning cycles is not specified, the tests shall be carried out – in case of laundering
after 5 laundering cycles (one laundering cycle consisting of one washing and one drying), or – in case
of dry cleaning after 5 cycles of dry cleaning. This shall be reflected in the information supplied by the
manufacturer.
If the manufacturer’s instructions indicate that both cleaning methods are allowed, the test specimen
shall undergo the laundering procedure only.
NOTE Manufacturer’s instructions typically indicate one or several of the various methods and processes of
EN ISO 6330, EN ISO 3175, EN ISO 15797 and a qualification label according to EN ISO 30023 or equivalent as
standardized processes for cleaning.

calculations shall be carried out according to the parallel method as given in EN ISO 15831:2004. Tests
may be carried out on one clothing ensemble.
The resultant effective thermal insulation of the protective clothing ensemble shall be measured with
standard underwear C as specified by the manufacturer. If the manufacturer doesn`t specify any
underwear, standard underwear B (see Table B.1) shall be used.
Garments shall be tested with standard ensemble R as specified in Table B.1.
During the test with underwear B or a garment the manikin shall not be dressed with any hood not
attached to the garment, gloves or boots other than the standard items.
6.4 Air permeability, AP
Air permeability shall be measured from outside to inside in accordance with EN ISO 9237:1995 as the
arithmetic mean value out of 10 specimens. The mean value shall be used for classification of the
garment. Measurements shall be carried out at a pressure differential of 100 Pa and a test area of
2
20 cm .
In case that the composite material cannot be tested in one piece because of e.g. thick multilayer
samples, it is necessary to separate the individual components and measure the component with the
lowest value.
