Textiles - Heat transfer performance test methods - Plate method
1 Scope
This standard specifies the textile heat transfer performance test methods.
This standard applies to all types of textile fabrics and their products, coated fabrics, leather and multi-layer composite materials can be implemented by reference.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version applies to this article
Pieces. For undated references, the latest edition (including all amendments) applies to this document.
GB/T 6529 Textiles conditioning and testing standard atmosphere
3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Thermal resistance thermalresistance
Rct
The ratio of the temperature difference between the two sides of the specimen and the heat flux per unit area passing vertically through the specimen.
Note 1. This dry heat flux may be one or more of conduction, convection and radiation.
Note 2. The thermal resistance, Rct, is measured in Kelvin per Watt (m2 · K/W).
3.2
Heat transfer coefficient heattransmissioncoefficient
When there is a unit temperature difference on both sides of the specimen, the heat flux per unit area passing through the specimen is expressed in units of W/(m2 · K).
3.3
Clovel clovalue
clo
A unit of thermal resistance. In the temperature of 21 ℃, the relative humidity does not exceed 50%, the air flow does not exceed 0.1m/s environmental conditions,
When the sitter (whose basal metabolism is 58 W/m2) feels comfortable, the thermal insulation value of the person wearing the garment is 1 clo.
4 principle
The sample is covered on the test board, the test board and the floor and the surrounding protective plate are electrically controlled, and can maintain a constant temperature, so that the test board
The heat can only be emitted in the direction of the sample, and the heating power required for the test plate to maintain a constant temperature for a certain period of time is measured to calculate the heat of the sample
Resistance, heat transfer coefficient, Clohms.
