Weight Reduction Method: 90%RH~70%RH Weight Gain Method: 10%RH~98%RH (National standard requirement 38°C 90%RH) The definition of humidity refers to the relative humidity on both sides of the film, that is, the weight reduction method is the humidity of the test cup 100%RH- the humidity of the test chamber (10%-30%RH). The weight gain method is the humidity of the test chamber (10%RH~98%RH) - the humidity of the test cup is 0%RH When the temperature is not the same, the humidity range has changed, as follows: (the following humidity customers must provide dry air source, otherwise affect the humidity generation) Temperature 15°C-40°C humidity 10% Rh-98% RH; Temperature 45 ° C Humidity 10%-90%RH Temperature 50°C Humidity 10%-80%RH; Temperature 55 ° C Humidity 10%-70%RH |

The test principle of permeable cup weighing method is adopted. At a certain temperature, a specific humidity difference is formed on both sides of the sample, and the water vapor enters the dry side through the sample in the permeable cup
The water vapor transmittance and other parameters of the sample can be obtained by the change of the weight of the moisture-permeating cup with time.
