FIELD: physics, tests. ^ SUBSTANCE: invention is related to devices for testing of construction materials and may be used to detect moisture resistance of heat insulation materials of fibrous structure, in particular products of mineral wool. Device for moisture resistance testing of heat insulation fibrous material samples comprises untight chamber with detachable cover equipped with sources and controllers of water heating to boiling, inside of which there is a detachable meshy tray for installation of tested samples. Moreover, on detachable cover there is a standard instrument for detection of compressibility of fibrous heat insulation materials. Besides movable stem of standard instrument passes through detachable cover of untight chamber inside guide tube and rests on test sample via additionally introduced spatial frame, which eliminates distortions from effect of heat and moisture medium at sample in process of its moisture resistance testing, and on top and bottom of test sample, meshy gaskets are installed for even transfer of pressure to test sample. ^ EFFECT: development of device that has high efficiency in operation and improved authenticity of sample testing results. ^ 5 cl, 1 dwg |
