Introduction to Perpoability vepo & Test Transport

This paper focuses on various methods to test liquids and analyze the effect factors on test results. Meanwhile, outdoor sports are very active, outdoor clothing needs more attention. A good sports suit should be recognizable. River vepo perpoability is a very important factor.

WVT - Vapor Transport

WVT is a water vapor in which water flows through the region of the sample within a specified time at a speed of g / m² · h or g / m² · 24h under conditions in which the particle retains heat and humidity on both sides.

Description of WVP - Perpoability water vapor

The magnitude of the vapor exceeds the unbalanced sample area at the specified time at g / m² · Pa · h under the condition that the sample retains temperature and humidity on both sides, as well as n 'below the pressure drop in the vertical.
