European foreword
This document (prEN 16422:2023) has been prepared by Technical Committee CEN/TC 248 “Textiles
and textile products”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede CEN/TR 16422:2012.
EN 16422:2023 includes the following significant technical changes with respect to CEN/TR 16422:2012:
— updated normative references and move of all normative references into the Bibliography;
— informative Annex A becomes normative;
— informative Annex B has been replaced by an informative reference to EN 17534;
— informative references to manikin standards EN ISO 15831 and EN 17528 added;
— editorial changes were made throughout the document to bring it up-to-date.

Introduction
This document has been developed to help retailers, manufacturers and consumers with the evaluation
of thermoregulatory properties of textiles, and selection of the most appropriate methods to define their
individual material performance requirements.
In order to encourage the use of the widest possible selection of materials and technologies, this
document takes the form of advice and guidance on the tests or groups of tests which would verify the
defined performance characteristics of a material or a product composite. It summarizes the scope and
application of the test described and provides an indication of suggested range of results for the referred
test method or methods to allow the user to grade performance of the material under evaluation. Where
a choice of test methods is available for measuring the same parameter on a material, each is described
to allow the user of this document to select the most appropriate method for his/her requirements.
This document also introduces a system of three performance levels for the different thermoregulatory
properties:
— thermal insulation;
— water vapour transmission (breathability);
— air permeability;
— water penetration resistance and repellence;
— liquid sweat management.
The large differences in the conditions of use necessitate a flexible use of the properties and performance
levels. This allows a choice of the appropriate level for each property and so to compose a 'product
profile', adapted to each specific type of use. There is for example, a significant difference between
thermoregulatory properties required for outerwear clothing for cool, windy and rainy weather during
low activity, and socks for warm indoor use during intense physical or sport activity. In addition, the work
clothing for a shop assistant requires different properties of thermoregulation than the underwear
intended for skiing, or home wear for the elderly. The ambient temperature, ambient moisture, wind and
level of activity, the contact to skin or other layers of clothing influence the requirements.
At the point of issue, it is recognized that the industry is in a constant state of development with regard
to new technology for innovative fibres and performance applications, and that methods required to
evaluate these new technologies can in the future be different to those in this document. Subsequent
revisions will consider the addition of any new test methods required to keep advice current to the
industry and its changing needs.
This document includes an Annex A. In this Annex A, there is consideration for product design and use
situations, as material performance is not the sole contributory factor to the thermoregulatory
performance of the final product or ensemble in use. This Annex A also has examples of marking products.

1 Scope
This document specifies test methods available for the measurement of thermoregulatory properties of
textile materials for use in clothing 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 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 textile, phase change materials (PCM) and similar smart
materials for thermoregulation, for which CEN ISO/TR 23383 can give better guidance.
