This standard specifies the method of measuring far infrared properties of textiles by far infrared emissivity and temperature rise tests, and gives the evaluation of far infrared properties.
This standard applies to various textile products, including fibers, yarns, fabrics, nonwovens and their products. This standard may also serve as a reference for products made of other materials.
This standard does not involve the evaluation of medical function.
