Textiles - Solar UV protective properties - Part 1: Method of test for apparel fabrics
This European Standard specifies a method for the determination of the erythemally weighted ultraviolet (UV) radiation transmittance of standard conditioned apparel fabrics to assess their solar UV protective properties.
This method is not suitable for fabrics which offer protection at a distance such as umbrellas, shade structures or artificial sources.
NOTE This standard may not be appropriate for fabrics with small colour and construction variations.
Textilien - Schutzeigenschaften gegen ultraviolette Sonnenstrahlung - Teil 1: Prüfverfahren für Bekleidungstextilien
Diese Europäische Norm legt ein Verfahren zur Bestimmung der Durchlässigkeit der hinsichtlich Erythem gewichteten ultravioletten Strahlung für normgerecht konditionierte Bekleidungstextilien zur Feststellung ihrer Schutzeigenschaften gegen ultraviolette Sonnenstrahlung fest.
Dieses Verfahren ist nicht für Textilien geeignet, die einen Schutz aus einem Abstand bieten, wie zum Beispiel Schirme, Konstruktionen zur Abschattung oder Vergleichbares.
ANMERKUNG Diese Norm braucht nicht für Textilien mit kleinen Variationen in der Farbe und im Aufbau geeignet zu sein.
Textiles - Propriétés de protection contre le rayonnement UV solaire - Partie 1: Méthode d'essai pour étoffes destinées a l'habillement
La présente Norme européenne spécifie une méthode pour la détermination du facteur de transmission du rayonnement ultraviolet (UV) pondéré par la courbe d'érytheme d'étoffes pour vetements en conditionnement normal en vue 'évaluer leurs propriétés de protection contre le rayonnement UV solaire.
La présente méthode ne convient pas aux étoffes offrant une protection a distance telles que les parasols, les structures destinées a créer de l'ombre ou les sources de rayonnement artificielles.
NOTE La présente norme peut s'avérer inappropriée pour des étoffes comportant de petites variations de couleur et de structure.

EN 13758-1:2001 (E)5The total spectral transmittance is measured by irradiating the sample with monochromatic orpolychromatic UV radiation and collecting the total (diffuse and direct) transmitted radiation. In thecase of polychromatic incident radiation, the transmitted radiation is collected monochromatically. Theapparatus shall either irradiate the sample with a parallel beam and collect all transmitted radiationwith an integrating sphere or irradiate the sample hemispherically and collect a parallel beam oftransmitted radiation.5 ApparatusThe measurement device consists of the following:5.1A UV source, providing UV radiation throughout the wavelength range 290 nm to 400 nm.Suitable UV sources include Xenon arc lamps, Deuterium lamps and Solar simulators.5.2An integrating sphere, having total openings representing not more than 10 % of the internalspherical surface. The internal surface shall be lined with a highly reflective matt surface, e.g. bariumsulphate paint. It shall be fitted with baffles to shield the inner detector or the inner source from thespecimen port and, if applicable, the sphere wall where the incident flux is measured.5.3A monochromator, suited for measurements with a spectral bandwidth of 5 nm or less in thewavelength region 290 nm to 400 nm.5.4UV transmitting filter, which transmits significantly only at wavelengths less thanapproximately 400 nm and which does not fluoresce.5.5A specimen holder to hold a specimen in a flat, tensionless or in a predefined stretched state.This device shall not obstruct the entrance port of the integrating sphere and shall ideally position thefabric in the plane of the integrating sphere port.In the case where a parallel incident beam is used, the surface of the beam should be at least 25 mm2and should cover at least 3 times the repeat fabric construction. Moreover, in the case of amonochromatic incident beam and for reducing the sample recess error, the ratio of the smallestdimension of the port of the integrating sphere to the largest dimension of the illumination patch shallalso be larger than 1,5. The beam should be normal to the fabric to within ± 5 degrees. The angulardivergence of the beam should be less then 5 degrees about the beam axis. These conditions shouldapply to the collected beam if diffuse illumination is used.A suitable UV transmitting filter shall be positioned between the sample and the detector if theinstrument monochromates before the sample.
