Conservation of cultural property - Test methods - Determination of water vapour permeability (δp)

This European Standard specifies a method for determining the water vapour permeability (WVP) of porous inorganic materials used for and constituting cultural property. The method may be applied to porous inorganic materials either untreated or subjected to any treatment or ageing.

Erhaltung des kulturellen Erbes - Prüfverfahren - Bestimmung des Wasserdampfleitkoeffizienten (δp)

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Wasserdampfleitkoeffizienten (WVP) von porösen anorganischen Materialien fest, die an kulturellem Erbe Verwendung finden. Das Verfahren darf auf entweder unbehandelte oder behandelte oder durch Alterung beanspruchte poröse anorganische Materialien angewendet werden.

Conservation des biens culturels - Méthodes d'essai - Détermination de la perméabilité à la vapeur d'eau (δp)

La présente Norme européenne définit une méthode d’essai permettant de mesurer la perméabilité à la vapeur d’eau (PVE) des matériaux inorganiques poreux constituant des biens culturels. La méthode peut être appliquée aux matériaux inorganiques poreux non traités, soumis à un traitement quelconque ou faisant l’objet d’un vieillissement naturel.

Ohranjanje kulturne dediščine - Preskusne metode - Določanje prepustnosti vodne pare (δp)

Ta evropski standard določa metodo za določanje prepustnosti vodne pare  (WVP) poroznih neorganskih materialov, ki se uporablja za kulturno dediščino ter jo določa. Metoda se lahko uporablja tako za porozne neorganske materiale, ki niso obdelani, kot tudi tiste, ki so podvrženi kakršnikoli obdelavi ali staranju.
