3 Terms and definitions

The following terms and definitions as defined in GB/T 15557 apply to this document.

3.1 Wet resistance

Ret

The ratio of the water vapor pressure difference on both sides of the sample to the evaporation heat flow rate per unit area passing through the sample. Evaporative heat flow may be caused by diffusion and

One or more forms of convection are passed.

Note 1. The moisture resistance Ret is in squares per square watt (m2·Pa/W), which means that the textile is under a stable water vapor pressure gradient condition.

The evaporating heat flow rate of a given area.
