Scope

Scope: This document specifies the terms and definitions, requirements, test methods, inspection rules, marking, packaging, transportation, and storage for cold-weather clothing. This document applies to all adult cold-weather clothing manufactured with textile fabrics as the main material, various insulating materials as fillings, or animal fur and artificial fur as linings or inner layers. Main technical content: 3. Terms and definitions: The following terms and definitions apply to this document. 3.1 Cold-weather clothing: Clothing with cold-weather and insulating functions, including single-piece or multi-piece garments such as upper garments, lower garments, and jumpsuits. 3.2 Thermal resistance (Rct): The ratio of the temperature difference between the two sides of the sample to the heat flux per unit area passing through the sample vertically. Note 1: This heat flux may include one or more forms of conduction, convection, and radiation. Note 2: Thermal resistance is expressed in units of m2·K/W. [Source: GB/T 11048-2018, Section 2.1] 3.3 Total thermal insulation of clothing (Itr): The total thermal insulation from the skin to the ambient air layer, measured using a dynamic thermal manikin under specified conditions. 3.4 Resultant effective thermal insulation (Icler): The thermal insulation from the skin to the outer surface of a single garment or suit, measured or calculated using a dynamic thermal manikin under specified conditions. 3.5 Water-vapour resistance (Ret): The ratio of the water vapour pressure difference between the two sides of the sample to the evaporation heat flux per unit area passing through the sample vertically. Note 1: The evaporation heat flux may be formed by diffusion and convection. Note 2: Water-vapour resistance (Ret) is expressed in units of m2·Pa/W.
