Steam Quality (Pure Steam) for Pharmaceutical use shall be ensured by- 1. Test for Level Non- Condensable Gases (Oxygen, Carbon di-oxide, Nitrogen, Ammonia, and some halogenated hydrocarbon gases etc). Limit= Should not be more than 3.5 %. 2. Dryness Value Test or Moisture Level in Steam 0.90- For porous Loads 0.95- For Metal Loads Excess moisture in steam will cause dumping of Loads. Less moisture cause raising of superheat value. Value for porous Load= Value for Non-porous Load= 3. Super heat value of steam at expansion tube. 25 degree Celsius
