Scope

Scope: This standard specifies a method for testing the thermal resistance of adult garments using a torso warm-body test. This standard applies to the thermal resistance testing of adult garments. This standard does not apply to the thermal resistance testing of infant and children's clothing. Main technical content: 1. Scope: This standard specifies a method for testing the thermal resistance of adult garments using a torso warm-body test. This standard applies to the thermal resistance testing of adult garments. This standard does not apply to the thermal resistance testing of infant and children's clothing. 2. Normative references 3. Terms and definitions: The terms and definitions defined in GB/T 11048 and the following terms and definitions apply to this document. 3.1 Thermal resistance: The ratio of the temperature difference between the two sides of the sample to the heat flux per unit area passing vertically through the sample. Thermal resistance is expressed in units of m2?K/W. 3.2 Base ensemble upwears: The reference inner garments worn with the warm body when testing the garments to be tested. 3.3 Clothing thermal resistance: The resistance of clothing to heat flow during the heat exchange between humans and the environment. 3.4 Clo value: A unit of thermal resistance. Under the environmental conditions of a temperature of 21°C and an airflow of no more than 0.1 m/s, when a person (with a basal metabolic rate of 58 W/m2) feels comfortable, the insulation value of the clothing they are wearing is 1 clo value. 4. Principle: Place the torso warm-body in a stable climate chamber, put on the single garment or combination garment (for coat-type samples, a reference inner garment must be worn) to be tested, simulate the heat exchange process between the human body, clothing, and environment under the state of human clothing, and calculate the total thermal resistance of the warm-body and clothing system by measuring the temperature difference between the surfac
