Traditionally humidity is not a factor that is given much consideration. Because some of our team of packaging engineers actively engages with members on ASTM committees, we are learning the standard will be updated in the future to accommodate this factor. Since ASTM 1980 does not call out what the humidity should be set to, it is best practice to keep the humidity low. Just like heightened temperature, high humidity can create defects that are not relative to the real-world environment the sterile barrier packaging will experience. Our goal is to target less than 20% Relative Humidity (RH) for accelerated aging studies.
