Flexible sheets for waterproofing - Determination of emissivity

This European Standard specifies the method to determine the emissivity of plastic, rubber and bitumen vapour control layers, underlays for walls and underlays for discontinuous roofing.
It also defines a conditioning procedure for these product families in order to quantify the sensitivity of emissivity to humidity and temperature.

Abdichtungsbahnen - Bestimmung des Emissionsgrades

Diese Europäische Norm legt das Verfahren zur Bestimmung des Emissionsgrades von Kunststoff-, Elastomer- und Bitumendampfsperrbahnen sowie von Unterdeck- und Unterspannbahnen für Wände und für Dachdeckungen fest.
Darüber hinaus ist ein Konditionierungsverfahren für diese Produktfamilien festgelegt, um die Empfindlichkeit des Emissionsgrades gegenüber Luftfeuchte und Temperatur zu ermitteln.

Feuilles souples d'étanchéité - Détermination de l'émissivité

La présente norme européenne spécifie la méthode de détermination de l’émissivité des écrans souples plastiques, élastomères et bitumineux, écrans souples pour murs extérieurs et écrans souples de sous-toiture pour couverture en petits éléments discontinus.
Elle définit également un mode opératoire de conditionnement pour ces familles de produits, afin de quantifier la perte potentielle d’émissivité en fonction de l’humidité et de la température.

Hidroizolacijski trakovi - Ugotavljanje emisivnosti

Ta evropski standard določa metodo za ugotavljanje emisivnosti plastičnih, gumijastih in bitumenskih plasti za nadzor hlapov, podložnih folij za stene in podložnih folij za prekinjene strehe. Prav tako določa postopek za pogoje za te družine proizvodov, da se ovrednoti občutljivost emisivnosti na vlago in temperaturo.

2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
EN 13416, Flexible sheets for waterproofing — Bitumen, plastic and rubber sheets for roof waterproofing — Rules for sampling 3 Terms and definitions For the purposes of this document, the following terms and definitions apply 3.1 emissivity emissivity of a material (usually written 0) is the ratio (proportion) of the energy radiated by a surface relative to the energy radiated by a blackbody at the same temperature. It is a measure of a material's ability to radiate heat 3.2 blackbody blackbody is a theoretical object that absorbs all electromagnetic radiation that falls on it at all wavelengths. No electromagnetic radiation passes through it and none is reflected NOTE A blackbody is also a perfect emitter with a normal and corrected emissivity of 1.
3.3 TIR Thermal Infrared Radiation principle
4 Symbols For the purposes of this document, the following symbols apply c specific heat capacity is the measure of the heat energy required to increase the temperature of a unit quantity of a substance by a certain temperature interval.
the wavelength
is the distance between repeating units of a propagation wave of a given frequency. NOTE In this document it is understood the wave length is limited to the infrared light spectrum.
(epsilon) emissivity (see above definition of emissivity)
(0 ≤ 0 ≤ 1).
(rho) reflectivity coefficient is the proportion of the incident electromagnetic radiation reflected from a surface or an optical element.
