Conservation of cultural property - Test methods - Determination of static contact angle
This European Standard specifies a method for the measurement of the static contact angle of a water drop on 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 - Messung des statischen Kontaktwinkels
Diese Europäische Norm legt ein Prüfverfahren zur Messung des statischen Kontaktwinkels eines Wasser-tropfens auf porösen anorganischen Materialien fest, die an kulturellem Erbe Verwendung finden. Das Verfahren darf auf entweder unbehandelte oder behandelte oder durch Alterung beanspruchte poröse anorga-nische Materialien angewendet werden.
Conservation des biens culturels - Méthodes d'essai - Détermination de l'angle de contact statique
La présente Norme européenne définit une méthode permettant de mesurer l'angle de contact statique d'une goutte d'eau sur les matériaux inorganiques poreux utilisés pour des biens culturels et constituant des biens culturels. La méthode peut être appliquée aux matériaux inorganiques poreux non traités, soumis à un traitement quelconque ou à un vieillissement.
Ohranjanje kulturne dediščine - Preskusne metode - Določanje statičnega kota omočenja
Ta evropski standard opredeljuje metodo za merjenje statičnega kota omočenja kaplje vode na porozne neorganske materiale, 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.

static contact angle, in degrees 6 Test equipment 6.1 Test equipment for the measurement of static contact angle consists of: i) an illumination source (1) that will not affect the temperature of the drop/specimen system, ii) a flat sample holder (2), iii) a drop deposition system, usually consisting of a graduated micro-pipette (3), with a flat head needle, positioned above and perpendicular to the specimen surface and able to deliver reproducible drops, iv) an optical system (4) that projects the image of the deposited water drop onto a screen (5) on which the height of the water drop and the diameter of the contact surface can be marked with a ruler (6). This part of the instrument can consist of a camera (4) able to record the image on a screen (5) where the parameters can be measured manually or automatically. The measurement principle of most commercial instruments available on the market is shown in Figure 2.
