Physiological tests
1. Measuring the Thermal and Moisture Resistance - Thermal and moisture resistance of textiles can be measured by the skin model which simulates the skin's physiological reaction very closely. The skin model imitates the contact of the textile layer with the skin and allows the determination of the total thermal resistance from the skin to the surrounding air.
2. Measurement of effective thermal (and moisture) resistance of clothing with a life-size model - The above mentioned methods of measurement deal with the comfort characteristics of textile fabrics only, but the physiological properties of a clothing system are also influenced by the air within the system and the air adhering to its outer surface. To include these influences in the measurement without the need for a test person, a life size model may be used. The Institute for the Physiology of Clothing, at Hohenstein in Germany has a model which is placed in a climatic chamber with defined variable ambient conditions.
3. Controlled Wear Tests - Test persons may also be used wearing the whole clothing system with sensor elements. They rest or perform standardised tasks in a climate controlled chamber with defined variable ambient conditions. |
