T/SQICA 010-2024 The classification and evaluation of insulation performance of down feathers
Basic Information
Scope
Scope: This document specifies the method for determining the thermal insulation performance of down and feathers. This document is applicable to the detection of down and feathers and their products as fillings; Main technical content: Cover the sample on the test plate. The test plate and the thermal protection ring around it, as well as the protective plate at the bottom, can all maintain a constant temperature, so that the heat of the test plate can only be dissipated through the sample, and the air can flow parallel to the surface of the sample. After the test conditions reach a stable state, the thermal resistance value of the measured material can be obtained by subtracting the thermal resistance value of the air layer from the thermal resistance value of the measured sample added with an air layer.
