How can we determine the appropriate conditions for humidity controls during manufacturing?

Case Study 104PB

Proj.ID/DIMS: HYG-20050221/D21299

Let us consider Product A having the moisture uptake rate of

• 0.8 mg/min. at 43.2 %RH,
• 2.2 mg/min. at 75.3 %RH, and
• 3.0 mg/min. at 93.6 %RH.

What %RH control would be required to encapsulate Product A?

Based on the measurements we can extrapolate the maximum allowed humidity (i.e. 28 %RH at 0 mg/min. moisture uptake rate)
