Textiles in the healthcare system
Textiles utilisés dans le domaine de la santé Textilien im Gesundheitswesen
This European Prestandard (ENV) was approved by CEN on 14 March 2002 as a prospective standard for provisional application.
The period of validity of this ENV is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the ENV can be converted into a European Standard.
CEN members are required to announce the existence of this ENV in the same way as for an EN and to make the ENV available promptly
at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the ENV) until the final
decision about the possible conversion of the ENV into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

3.2.3
colour fastness

as fastness ratings
[EN ISO 105-A01]
3.2.4
dimensional change
change in length and/or width of fabrics, garments or other textile articles which may occur when subjected to an
appropriate combination of specified washing and drying procedures

3.2.6
liquid absorbency time (wettability)
time required for a test specimen of fabric to become completely wetted by the test liquid and imbibe test liquid into

tensile strength
maximum tensile force recorded in extending a test-piece to breaking point, the tensile force recorded at the

NOTE The tensile strength and tensile strength at break may be different. If after yield the elongation continues and is
accompanied by a drop in force resulting in tensile strength at break being lower than tensile strength.
3.2.10
thermal resistance, R
ratio of the temperature difference between two faces of a test specimen to the rate of flow of heat per unit area
normal to the faces. It is analogous to eletrical resistance in the case of current flow through an electrical conductor
[ISO 5085-1]
3.2.11
water penetration
hydrostatic head supported by a fabric. It is measure of the opposition to the passage of water through the fabric
[EN 20811]
3.2.12
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. The evaporative heat flux may consist of both diffusive and convective
components
