ASTM F1291 1720 Warm Body Sweating Dummy Tester Human Body Heat Exchange Simulation Test Machine
Introduction
The warm body sweating dummy tester can simulate the heat exchange processes of conduction, convection, radiation between the human body, clothing and the environment, as well as the moisture exchange process of sweating in a set environment. It scientifically evaluates the thermal performance of the clothing or the environment as a whole, avoiding the need for human testing, achieving dataization, standardization of the perception results, high experimental accuracy, good repeatability, and can guide the research and production of functional fabrics and clothing. It can also be used to analyze the impact of the environment on human comfort and obtain the environmental conditions that meet human comfort requirements.
Compliant with standards
