EN ISO 15758:2014

Hygrothermal performance of building equipment and industrial installations - Calculation of water vapour diffusion - Cold pipe insulation systems (ISO 15758:2014)

ISO 15758:2014 specifies a method for calculating the density of the water vapour flow rate in cold pipe insulation systems, and the total amount of water diffused into the insulation over time. The calculation method presupposes that water vapour can only migrate into the insulation system by diffusion, with no contribution from airflow. It also assumes the use of homogeneous, isotropic insulation materials so that the water vapour partial pressure is constant at all points equidistant from the axis of the pipe.
ISO 15758:2014 is applicable when the temperature of the medium in the pipe is above 0 °C. It applies to pipes inside buildings as well as in the open air.

Wärme- und feuchtetechnisches Verhalten von haus- und betriebstechnischen Anlagen - Berechnung der Wasserdampfdiffusion - Dämmung von Kälteleitungen (ISO 15758:2014)

Diese Internationale Norm legt ein Verfahren zur Berechnung der Wasserdampf-Diffusionsstromdichte in Dämmsystemen für Kälteleitungen und der durch die Dämmung über die Zeit aufgenommenen Wassermenge fest. Bei diesem Berechnungsverfahren wird davon ausgegangen, dass die Absorption von Wasserdampf durch das Dämmsystem nur durch Diffusion ohne Mitwirkung einer Luftströmung erfolgt. Ferner wird davon ausgegangen, dass homogene isotrope Dämmstoffe verwendet werden, so dass der Wasserdampfteildruck an allen Punkten, die von der Rohrachse einen gleichen Abstand haben, konstant ist.
Die Norm gilt für Rohre im Inneren von Gebäuden sowie im Freien, wenn die Temperatur des im Rohr befindlichen Mediums über 0 °C liegt

Performance hygrothermique des équipements de bâtiments et installations industrielles - Calcul de la diffusion de vapeur d'eau - Systèmes d'isolation de tuyauteries froides (ISO 15758:2014)

L'ISO 15758:2014 donne une méthode permettant de calculer la densité du flux de vapeur d'eau dans les systèmes d'isolation de tuyauteries froides, ainsi que la quantité totale d'eau diffusée dans l'isolation au cours du temps. La méthode de calcul suppose que la vapeur d'eau ne peut migrer dans le système d'isolation que par diffusion, sans aucune contribution d'un flux d'air. Elle suppose également l'utilisation de matériaux isolants homogènes et isotropes, de telle sorte que la pression partielle de vapeur d'eau soit constante en tout point équidistant de l'axe du tuyau.
L'ISO 15758:2014 s'applique lorsque la température du fluide circulant dans le tuyau est supérieure à 0 °C. Elle s'applique aussi bien aux tuyauteries situées à l'intérieur de bâtiments qu'à celles situées à l'air libre.

Higrotermalno obnašanje opreme stavb in industrijskih inštalacij - Izračun difuzije vodne pare - Sistemi za izoliranje hladnih cevi (ISO 15758:2014)

Standard EN ISO 15758 določa metodo za izračun gostote hitrosti pretoka vodne pare v sistemih za izoliranje hladnih cevi ter skupne količine vode, sčasoma difundirane v izolacijo. Metoda izračuna predpostavlja, da lahko vodna para v sistem za izoliranje preide samo z difuzijo, brez prispevka pretoka zraka. Predvideva tudi uporabo homogenih, izotropnih izolacijskih materialov, da je delni tlak vodne pare stalen na vseh točkah, enako oddaljenih od osi cevi. Ta mednarodni standard se uporablja, kadar je temperatura medija v cevi nad 0 °C. Uporablja se za cevi v stavbah in na prostem.
