Full title and description

Textiles — Physiological effects — Measurement of thermal and water-vapour resistance under steady-state conditions (sweating guarded-hotplate test). This International Standard specifies a laboratory method using a sweating guarded‑hotplate to determine thermal resistance and water‑vapour (evaporative) resistance of fabrics, films, coatings, foams, leather and multilayer assemblies intended for clothing, quilts, sleeping bags, upholstery and similar products.

Abstract

ISO 11092:2014 specifies methods for measurement of thermal resistance and water‑vapour resistance under steady‑state conditions using a sweating guarded‑hotplate. The procedure covers single and multilayer textile assemblies and defines applicability limits tied to the apparatus (for example, minimum-equipment limits cited in the standard are approximately 2 m²·K/W for thermal resistance and 700 m²·Pa/W for water‑vapour resistance). The method is intended for laboratory determination of physiological properties relevant to comfort and performance of textile products.

Scope

Defines a steady‑state laboratory test (the sweating guarded‑hotplate) to measure thermal resistance and water‑vapour resistance of textile materials and assemblies used in clothing and similar products. The scope includes fabrics, films, coatings, foams and leather, and multilayer combinations; it also specifies limitations on maximum measurable resistances that depend on the apparatus design and dimensions. The method is intended for research, product development and quality assessment of comfort-related properties.

Key topics and requirements

• Measurement principle: sweating guarded‑hotplate (steady‑state) method for combined thermal and evaporative resistance testing.
• Test specimen types: single-layer and multilayer textile assemblies, films, coatings, foams and leather.
• Apparatus specification: requirements for guarded‑hotplate construction, heat flow control, sweating simulation, sensors and environmental control to achieve steady state.
• Performance limits: practical measurement upper limits tied to apparatus dimensions (example minimum-equipment limits cited in the standard: ~2 m²·K/W thermal resistance and ~700 m²·Pa/W water‑vapour resistance).
• Test conditions and reporting: conditioning, test atmosphere, specimen mounting, data reduction and required reporting elements for reproducibility and inter‑laboratory comparison.

Typical use and users

Used by textile and apparel laboratories, product developers, quality managers, standards bodies, research institutes and manufacturers of clothing, outdoor equipment (sleeping bags, quilts), upholstery and personal protective equipment where thermal comfort and evaporative resistance are relevant. Laboratories performing comfort testing, conformity assessment and comparative product evaluation commonly adopt this method.

Related standards

ISO 11092:2014 replaces earlier editions (ISO 11092:1993 and its 2012 amendment). It is referenced by subsequent textile test methods that use the sweating guarded‑hotplate principle (for example ISO 21232 series for microclimate/moisturizing-effect measurements) and has regional/adopted variants such as UNE‑EN ISO 11092. Comparable test methods (different organizations) include ASTM test methods for thermal/evaporative resistance using a sweating hot plate.

FAQ

Q: What is this standard?

A: ISO 11092:2014 is an International Standard that specifies a laboratory method (sweating guarded‑hotplate, steady‑state) to measure the thermal resistance and water‑vapour (evaporative) resistance of textile materials and assemblies.

Q: What does it cover?

A: It covers the test apparatus requirements, specimen preparation and mounting, environmental conditions, measurement procedure, limits of applicability (dependent on apparatus), data reduction and required reporting for fabrics, films, coatings, foams, leather and multilayer textile assemblies used in clothing and related products.

Q: Who typically uses it?

A: Textile and apparel manufacturers, test laboratories, R&D teams, standards organizations and suppliers of thermal‑comfort products (clothing, sleeping bags, upholstery) use this standard for product development, comparison and quality control.

Q: Is it current or superseded?

A: ISO 11092:2014 is listed as the current Edition 2 (2014). The ISO record shows the publication was reviewed and confirmed in the ISO review cycle (confirmation in 2020) and the document is in the ISO lifecycle for revision activity, so users should check for any newer FDIS or published replacement if absolute currency is critical.

Q: Is it part of a series?

A: It is part of the family of textile physiological‑effects test methods and is referenced by related standards (for example ISO 21232 series). Regional adoptions (UNE‑EN ISO 11092) and comparable methods (e.g., ASTM sweating hot‑plate methods) exist that align with or complement ISO 11092.

Q: What are the key keywords?

A: Sweating guarded‑hotplate; thermal resistance; evaporative/water‑vapour resistance; textile comfort; physiological effects; steady‑state testing; ISO 11092.
