CEN/TC 248/WG 28 - Thermoregulation

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.

This method of test specifies a test method for determining the thermal resistance of textile articles which may be filled, e.g. padded coats and jackets, child sleep bags, cot duvets, etc., or textiles articles with a thermal resistance of up to 0,5 m2K/W (5,0 tog) and/or which do not have uniform thickness.
The test method is applicable to products with a thermal resistance within the range 0,025 m2K/W (0,25 tog) to approximately 0,5 m2K/W (5,0 tog) but is limited only by the ability of the test apparatus to cope with the thickness of the test sample.

This document specifies a test method for measuring liquid sweat management properties of knitted, woven and nonwoven textile fabrics, namely buffering index, sweat transport and sweat uptake.

This document specifies the requirements of the sweating manikin and the test procedure used to measure the water vapour resistance of a clothing ensemble, as it becomes effective for the wearer in practical use in a defined environment, with the wearer either standing or moving. This water vapour resistance, among other parameters, can be used to determine the effect of clothing on the physiology of the wearer in specific climate/activity scenarios.

This Technical Report outlines test methods available for the measurement of thermoregulatory properties of textile materials for use in clothing, and provides guidance on the most suitable methods for selection where choices are available to the user.
The document also provides classification of the thermoregulatory properties in three performance levels.
This Technical Report excludes consideration for the thermoregulatory properties of Personal Protective Equipment (PPE) and clothing items or textile products for which a standard already specifies a particular requirement.
This Technical Report excludes also phase change materials (PCM) and similar smart materials for thermoregulation, for which CEN/TR 16298 may give better guidance.
