ISO 11092 (EN 31092)

Description of the test
Textiles -- Physiological effects -- Measurement of thermal and water-vapour resistance under steady-state conditions.

  • The test fabric is placed on the surface of a porous metal plate.
  • The plate is heated and water is channeled into the metal plate, simulating perspiration. The plate is then kept at a constant temperature.
  • As water vapor passes through the plate and the fabric, it causes Evaporative Heat Loss and therefore more energy is needed to keep the plate at a constant temperature.
  • Ret is the measurement of the resistance to evaporative heat loss. The lower the Ret value, the less resistance to moisture transfer and therefore higher breathability.

Third Party Validation
