This document specifies test methods available for the measurement of thermoregulatory properties of textile materials for use in garments and gives guidance on the most suitable methods for selection where choices are available to the user. This document also establishes classification of the thermoregulatory properties in three performance levels. This document does not apply to garments or clothing intended to be worn by babies, infants and children whose thermoregulation within the body has not yet been fully developed. This document does not apply to the thermoregulatory properties of personal protective equipment (PPE) and clothing items or textile products for which a standard already specifies a particular requirement. This document does not apply also to heated textiles, phase change materials (PCM) and similar smart materials for thermoregulation, for which CEN ISO/TR 23383 can give better guidance.
