Test Principle
Clothing is often made of materials that impede the flow of heat and moisture from the skin to the environment. Consequently, people may suffer from heat stress or cold stress when wearin clothing in different environmental conditions. Therefore, it is important to quantify the thermal resistance and evaporative resistance of clothing materials and to consider these properties when selecting materials for different clothing applications.
Application
Measurement of the thermal resistance and the evaporative resistance, under steady-state conditions, of fabrics, films, coatings, foams, and The quilt, including multi-layer assemblies, for use in Clothing production.
Configuration
Standard configuration: host test unit, a power line, LABTest analysis PC software
Optional accessories: Climate Chamber.
