NF EN 31092

<p>ISO 11092:2014 specifies methods for the measurement of the thermal resistance and water-vapour resistance, under steady-state conditions, of e.g. fabrics, films, coatings, foams and leather, including multilayer assemblies, for use in clothing, quilts, sleeping bags, upholstery and similar textile or textile-like products.</p> <p>The application of this measurement technique is restricted to a maximum thermal resistance and water-vapour resistance which depend on the dimensions and construction of the apparatus used (e.g. 2 m²·K/W and 700 m²·Pa/W respectively, for the minimum specifications of the equipment referred to in ISO 11092:2014).</p>
