What is EN ISO 14158:2013?

EN ISO 14158:2013 is a technical standard that provides guidelines for determining the thermal resistance of textiles. It specifies a test method, equipment requirements, and procedures for conducting the test. This standard is important in the textile industry as it helps ensure the quality and performance of textile products.

Importance of Thermal Resistance in Textiles

Thermal resistance is a measure of a material's ability to resist heat transfer. In the context of textiles, thermal resistance is crucial as it directly impacts the comfort and functionality of clothing. Textiles with high thermal resistance can provide insulation, keeping the wearer warm in cold conditions, while those with low thermal resistance allow heat to escape, keeping the wearer cool in hot weather.

The Test Method

The test method described in EN ISO 14158:2013 involves placing a textile sample between a heated plate and a cooled plate. The temperature difference between the two plates is maintained for a certain period of time, and the rate of heat transfer through the sample is measured. By analyzing the data obtained from the test, the thermal resistance of the textile can be determined.

Equipment Requirements and Procedures

EN ISO 14158:2013 also specifies the equipment requirements for conducting the thermal resistance test. It provides detailed instructions on how to set up the testing apparatus, including the dimensions of the plates, the temperature control parameters, and the calibration procedures. Furthermore, the standard outlines the procedures for sample preparation, test conditions, and data analysis.
