Full title and description

ISO 13029:2012 — Textiles — Determination of drying rate in dynamic state by the modified sweating‑guarded hotplate. This International Standard specifies a laboratory method to measure the drying behaviour (drying rate) of textile products with moisture‑management properties, primarily intended for sportswear, leisure garments and underwear that contact the skin.

Abstract

ISO 13029:2012 defines a test procedure using a modified sweating‑guarded hotplate (based on the SGHP concept) to evaluate drying rate under dynamic conditions (to characterise moisture management and drying performance rather than steady‑state thermal properties). The method uses distilled water to avoid artefacts from artificial sweat and is intended for fabrics that are vapour‑permeable and not thicker than 5 mm; it provides comparative drying information rather than direct physiological comfort metrics.

Scope

This standard specifies a laboratory test for measuring the drying rate of fabric products in a dynamic state using a modified sweating‑guarded hotplate apparatus. It is aimed at fabrics and products used next to the skin (sports, leisure, underwear). The method excludes textile materials that are impermeable to water vapour and those with thickness greater than about 5 mm. The procedure is intended to provide comparative drying performance under defined, limited environmental conditions rather than to assess physiological comfort directly.

Key topics and requirements

• Use of a modified sweating‑guarded hotplate (SGHP) arrangement to simulate dynamic drying conditions and measure mass‑loss/drying rate.
• Specimen preparation and mounting to represent fabrics used next to skin (sports/leisure/underwear).
• Requirement that tested textiles be vapour‑permeable and ≤ ~5 mm thick; materials outside those limits are not applicable.
• Use of distilled water (rather than artificial sweat) in the test to reduce analytical errors.
• Controlled environmental/test conditions and reference to calibration/steady‑state SGHP practice where relevant.

Typical use and users

Test laboratories, textile R&D and quality departments, manufacturers of performance apparel (sportswear, underwear, leisurewear), independent test houses and compliance/certification bodies use ISO 13029 to compare drying performance of fabrics and finished garments or to support product development and claims about moisture‑management/drying behaviour.

Related standards

ISO 13029 complements other textiles test methods for thermal and moisture properties. In particular ISO 11092 (sweating guarded‑hotplate test — steady‑state measurement of thermal and water‑vapour resistance) is closely related and provides the steady‑state SGHP method on which the modified dynamic technique is based. National/adopted versions and translations (for example GOST/R adoptions) exist for jurisdictions that publish national equivalents.

FAQ

Q: What is this standard?

A: ISO 13029:2012 is an ISO test method that specifies a laboratory procedure to measure the drying rate of textile products in a dynamic state using a modified sweating‑guarded hotplate.

Q: What does it cover?

A: It covers test apparatus modifications, specimen preparation and test procedure to obtain comparative drying‑rate data for vapour‑permeable textiles (primarily sports, leisure and underwear fabrics) under defined conditions; it excludes non‑vapour‑permeable materials and textiles thicker than about 5 mm.

Q: Who typically uses it?

A: Textile laboratories, manufacturers (R&D and QA), test houses and certification bodies that need objective, repeatable comparisons of fabric drying behaviour for product development, claims substantiation and quality control.

Q: Is it current or superseded?

A: ISO 13029:2012 is published and has been confirmed in subsequent ISO reviews (the text is listed as confirmed in ISO records); users should check their national standards body for any national adoptions or later revisions.

Q: Is it part of a series?

A: It is not a multi‑part series itself but is conceptually linked to the SGHP family of test methods (notably ISO 11092 for steady‑state thermal/water‑vapour resistance); it should be used alongside other textile performance standards when assessing overall garment comfort and performance.

Q: What are the key keywords?

A: Drying rate; dynamic drying; sweating‑guarded hotplate; moisture management; water‑vapour permeability; textiles; sportswear; underwear.
