Method, device and test specimen for dynamic testing of building material thermal properties

摘要

method for dynamic testing of thermal properties of the material is based on the comparison of the temperature record at balancing temperature of liquids in containers (7) and (8) oddelenu00fdch in triple isolatedbox (5) prepu00e1u017ekou tvorenou tested the test sample (1), with prubehy temperatures identified by conforming experiment carried out on the reference or etalonovu00e9m material of known thermal characteristics.with the advantage of close to the subject material.the temperature t is scanned with at least in five places, in the center of a first vessel (7) hot liquidsin the center of the second container (8) cold liquids and in pru00edcnu00e9 axis of the test specimen (1) and that at least in three levels, with the advantage of 1 cm from the surface of the test sample (1), and in its midst.estimation of thermal conductivity is odvozovu00e1n from speed balancing temperature of liquids in containers (7) and (8) urcovanu00e9 in balanced temperature gradient in the test the test sample (1).mernu00e1 thermal capacity is derived from the changeprumernu00e9 temperature kapalinnu00fdch filling containers (7) and (8) reported to be after the settlement of their estimated on the basis of temperature or faster speed of thermal waves induced in the counter of the subject materiu00e1lu initial jump turn temperature some of the water filling of containers (7) and (8) or from the temperature difference merenu00fdch now in the test sample (1) teplomery (16) and (17).the pack is tvoreno triple isolated periodic ctyrboku00fdm box (5) with a first isolation layer (6) and with demountable lid (12) of the inner side of the second opatrenu00fdm isolation layer (13).in the middle of the box (5) and a lid (12) is created. the centre panel (12), the topic of the first side wall, and opposite to the third side wall of the box bottom (5) of the peripheral groove (9) for again
