Textiles - Physiological effects - Measurement of thermal and water-vapour resistance under steady-state conditions (sweating guarded-hotplate test) (ISO 11092:1993 + Amd.1:2012); German version EN 31092:1993 + A1:2012
Textilien - Physiologische Wirkungen - Messung des Wärme- und Wasserdampfdurchgangswiderstandes unter stationären Bedingungen (sweating guarded-hotplate test) (ISO 11092:1993 + Amd.1:2012); Deutsche Fassung EN 31092:1993 + A1:2012
This document (EN 31092:1993+A1:2012) has been prepared by Technical Committee ISO/TC 38 "Textiles", in collaboration with Technical Committee CEN/TC 248 "Textiles and textile products", the secretariat of which is held by BSI (United Kingdom). The responsible national committee is Working Committee NA 062-05-45 AA "Physiologische Prüfung von Textilien" ("Clothing physiological testing of textiles") at the Material Testing Standards Committee at DIN. This document specifies methods for the measurement of the thermal resistance and water-vapour-resistance, under steady-state conditions, of, for example, fabrics, films, coatings, foams and leather, including multilayer assemblies, for use in clothing, quilts, sleeping bags, upholstery and similar textile or textile-like products. The application of the measurement technique is restricted to specific maximum thermal resistance and water-vapour resistance values which depend on the dimensions and construction of the apparatus used (for example, 2 m2 K/W and 700 m2 Pa/W respectively, for the minimum specifications of the equipment referred to in this International Standard). The test conditions used in this standard are not intended to represent specific comfort situations, and performance specifications in relation to physiological comfort are not stated. This document (EN 31092:1993+A1:2012) contains Amendment A1:2012 for EN 31092:1993. Clause 5.3 "Test enclosure" and 7.2.1 have been modified and a new informative Annex C "Guidance on test specimen assembly for materials prone to swelling" has been incorporated.
