Поропласты. Определение коэффициента линейного термического расширения жестких материалов при температурах ниже температуры окружающей среды
Название (англ.):
Cellular plastics; Determination of the coefficient of linear thermal expansion of rigid materials at sub-ambient temperatures
Описание (англ.):
Specifies two methods for determing the coefficient of linear thermal expansion. Method A is the preferred method, it gives a value on a large sample at a chosen temperature. Method B should be employed to obtain an average coefficient for the temperature interval between the cryogenic temperature and the ambient temperature. In an annex the test apparatures for both methods are described in detail.
