Testing of microclimate properties
Using the equipment The Sweating Indentor, properties related to microclimate can be measured, which is essential for a product’s perceived comfort.
Syfte
For products with close-to-body use, such as clothes, furniture, and mattresses, their microclimate properties are important for them to be perceived as comfortable. Such properties are called “thermophysiological properties” within the comfort area, and are crucial for a product to be perceived as “moderately warm” and not cause discomfort due to sweating. By performing measurements with the sweating impression body, numerical values can be assigned to these material properties, which can be of great help in comparing different products and in product development.
Products for which this measurement method is suitable include: Beds, mattresses, seat cushions, and wound dressings.
Metod
The Sweating Indentor is heated to body temperature and contains water which can be released through a perforated surface in the form of water vapor at a rate that roughly corresponds to the moisture release from a human body at rest. The impression body can thus be considered to simulate a human body (which emits heat and moisture). By pressing the impression body against the test object, with a temperature and humidity sensor placed in the contact zone, the resulting temperature and relative humidity can be determined
Leverans
A test assignment results in measurement values for the microclimate that was measured, i.e., the temperature and relative humidity that the test body gave rise to. The test result is documented in a technical report.
