Поропласты. Определение проницаемости водяных паров через жесткие материалы
Название (англ.):
Cellular plastics; Determination of water vapour transmission rate of rigid materials
Описание (англ.):
This method provides the testing of rigid cellular materials,(thickness 3 to 80 mm), which may contain natural skins or adhered facings of different material. A test specimen is hermetically sealed to the open mouth of a test dish, containing a desiccant. This assembly is placed in an atmosphere, the temperature and humidity of which are controlled. Periodic weighings are made to determine the rate ofwater vapour transmission through the specimen into the desiccant.
