Introduction
TheThermal and Water-vapour Resistance Testeris a special measurement device used for measurement of thermal and water-vapour resistance under steady-state conditions („sweating guarded-hotplate test“) of textiles according to ISO 11092. is a special measurement device used for measurement of thermal and water-vapour resistance under steady-state conditions („sweating guarded-hotplate test“) oftextiles according to ISO 11092.
Working principle
The test method, as described in ISO 11092. is based on measurement of the heat losses through the sample in stable temperature (thermal resistance). Sample is placed on thehot plate; the hot plate is surrounded with active heat shields on all sides except for the side with the sample. Electrical power required to hold the hot plate temperature stable ismeasured and converted to temperature resistance of the sample: the better temperature resistance (better insulation), the lower power is needed.
The sample can be precisely moisturized in order to simulate human perspiration (and measure water-vapour resistance). To achieve this, the hot plate is porous and water can bepumped into the assembly. A digital regulator holds constant level of water/vapour mix in the hot plate assembly. The sample does not soak up with water as the sintered material of the hot plate is permeable only to water vapour.
The sample gets wet with the water vapour and is chilled with a wind, simulated with tangential fans: just like when wearing sweaty clothes. The air speed and turbulent flow areelectronically regulated. The water-vapour resistance is then measured from the hot plate heating power requirements.
Structure
The device consists of two parts: the hot plate device unit (HPD) and a trolley. The HPD is inserted into a customer-supplied climatic chamber. The trolley is then connected with the HPD by means of a water hose and an electrical connector.
