What is EN ISO 11092:2019?

EN ISO 11092:2019 is a technical standard that provides specifications for the measurement of thermal resistance and evaporative resistance of textiles, fabrics, and clothing. It is an important standard in the textile and apparel industry as it helps assess the thermal comfort properties of various products.

The Importance of Thermal Comfort

Thermal comfort plays a crucial role in our everyday lives. Whether we are outdoors or indoors, wearing the right clothing to maintain optimal body temperature is essential. This is where EN ISO 11092:2019 comes into play, helping manufacturers and consumers understand the performance of textiles and garments regarding their thermoregulatory properties.

Measuring Thermal Resistance

One of the key aspects covered by EN ISO 11092:2019 is the measurement of thermal resistance. This parameter quantifies how well a fabric or garment can insulate against heat transfer. The test method involves placing a fabric sample between two heat sources at different temperatures and measuring the resulting temperature difference. A higher thermal resistance value indicates better insulation properties.

Understanding Evaporative Resistance

In addition to thermal resistance, EN ISO 11092:2019 also addresses evaporative resistance. This property measures the ability of a textile or garment to allow sweat evaporation, thus regulating moisture and preventing discomfort caused by excessive perspiration. The test method involves exposing the sample to a controlled environment with specific humidity levels and measuring the rate of moisture transmission through the fabric.

Overall, EN ISO 11092:2019 is a comprehensive standard that aids in evaluating the thermal comfort performance of textiles and garments. By providing clear guidelines for measuring thermal resistance and evaporative resistance, it ensures that products meet the necessary requirements for maintaining optimal body temperature and moisture management. Manufacturers and consumers alike can rely on this standard to make informed decisions regarding the selection of suitable clothing for specific environmental conditions.
